揭秘新能源车主5大伪省电习惯：误操作竟让续航折半

揭秘新能源车主5大伪省电习惯：误操作竟让续航折半

“空调开26度最省电”“起步要像蜗牛一样慢”“下坡一定要挂空挡”……在新能源汽车保有量持续攀升的当下，诸如此类的“省电秘籍”在车主圈层中广泛流传，被不少追求长续航的车主奉为圭臬。

"Setting the air conditioner to 26 degrees is the most energy-efficient", "Starting should be as slow as a snail", "Must shift to neutral when going downhill",,, With the continuous rise in the ownership of new energy vehicles, such "energy-saving tips" have spread widely among car owners and are regarded as the golden rule by many car owners pursuing long battery life,

为了多跑出几十公里的续航，大量新能源车主在日常用车中严格践行这些操作，坚信只要将电耗压到极致，车辆续航就能无限接近厂商标称值。但现实往往事与愿违：他们小心翼翼地控制油门、紧盯电耗表，表显电耗确实维持在较低水平，可实际行驶里程却大打折扣；反观那些驾驶风格更为激进、“大脚油门起步、空调随意调节”的老司机，车辆续航反而表现得更为扎实。

To drive a few dozen more kilometers, a large number of new energy vehicle owners strictly practice these operations in daily use, firmly believing that as long as the power consumption is pressed to the limit, the vehicle's battery life can be infinitely close to the manufacturer's nominal value, But reality often backfires: they carefully control the accelerator and keep an eye on the power consumption meter, The displayed power consumption is indeed maintained at a low level, but the actual driving mileage is greatly reduced; on the contrary, those experienced drivers with a more aggressive driving style, such as "stepping on the accelerator hard when starting and adjusting the air conditioner at will", have a more solid vehicle battery life,

面对这种反差，不少车主心生疑惑：难道是自己的车出现了故障？其实并非如此。很多看似“省电”的操作，在物理规律和新能源汽车的核心工作逻辑面前，实则是彻头彻尾的“费电”行为。车主不仅无法达到省电目的，反而会因操作不当，导致电池提前进入“保护模式”或“低效工作区间”，最终造成续航大幅缩水。

Faced with this contrast, many car owners are confused: could there be a fault with their cars? Actually, that's not the case, Many operations that seem "energy-saving" are actually completely "power-consuming" behaviors in the face of physical laws and the core working logic of new energy vehicles, Car owners not only fail to achieve the purpose of saving electricity, but also cause the battery to enter the "protection mode" or "inefficient working range" in advance due to improper operation, eventually leading to a significant reduction in battery life,

基于此，我们打破传统认知误区，从能量守恒定律和新能源汽车电机、电池的核心特性出发，深入揭秘5个正在“偷走”续航的伪省电习惯，进而为广大车主科普真正科学高效的用车之道，帮助大家充分发挥车辆的续航潜力。

Based on this, we break the traditional cognitive misunderstandings, start from the law of conservation of energy and the core characteristics of motors and batteries of new energy vehicles, in-depth reveal 5 false energy-saving habits that are "stealing" battery life, and then popularize the real scientific and efficient way of using cars for the majority of car owners, helping everyone give full play to the battery life potential of the vehicles,

一、误区一：起步“蠕行”，温柔操作实则最费电

Myth 1: "Creeping" when starting, gentle operation is actually the most power-consuming

在新能源汽车车主群体中，普遍存在这样一种错误认知：“电机的扭矩输出大，起步时猛踩油门肯定会消耗大量电能，只要慢慢蹭着走，让电机功率保持在低位，就能实现最省电的效果。”这种认知看似符合“低功率对应低能耗”的常规逻辑，却忽略了电机的工作特性和车辆起步时的物理阻力规律。

Among the group of new energy vehicle owners, there is a common misunderstanding: "The torque output of the motor is large, Stepping on the accelerator hard when starting will definitely consume a lot of electrical energy, As long as you creep along slowly and keep the motor power at a low level, you can achieve the most energy-saving effect," This cognition seems to conform to the conventional logic of "low power corresponds to low energy consumption", but it ignores the working characteristics of the motor and the physical resistance law when the vehicle starts,

真相恰恰相反：起步过慢的“蠕行”操作，才是真正的“电老虎”，是导致续航缩水的重要原因之一。这一结论并非主观判断，而是基于基础物理原理的客观事实——汽车在起步瞬间，需要克服两大核心阻力：一是车辆与地面之间的静摩擦力，二是车辆自身的惯性阻力。这两大阻力在车辆静止状态向运动状态转变的过程中达到峰值，也是整个行驶过程中阻力最大的阶段。

The truth is just the opposite: the "creeping" operation with too slow a start is the real "power hog" and one of the important reasons for the reduction in battery life, This conclusion is not a subjective judgment, but an objective fact based on basic physical principles - when a car starts, it needs to overcome two core resistances: one is the static friction between the vehicle and the ground, and the other is the inertial resistance of the vehicle itself, These two resistances reach their peak during the transition of the vehicle from a static state to a moving state, which is also the stage with the greatest resistance in the entire driving process,

要理解这一原理，我们首先需要明确新能源汽车电机的核心特性。与传统燃油发动机不同，电机具有“扭矩瞬间爆发”的优势，在启动瞬间就能输出最大扭矩的80%以上，而燃油发动机则需要通过提高转速逐步提升扭矩。这一特性使得电机在克服起步阻力时，具备天然的效率优势，关键在于如何合理利用这一优势。

To understand this principle, we first need to clarify the core characteristics of new energy vehicle motors, Different from traditional fuel engines, motors have the advantage of "instant torque burst", which can output more than 80% of the maximum torque at the moment of startup, while fuel engines need to gradually increase torque by increasing speed, This characteristic enables the motor to have a natural efficiency advantage when overcoming starting resistance, and the key lies in how to reasonably use this advantage,

从能量消耗的逻辑来看，起步阶段的能耗高低，核心取决于“功率输出强度”与“持续时间”的乘积。我们可以将两种起步方式的能量消耗情况进行对比分析：

From the perspective of energy consumption logic, the level of energy consumption in the starting stage depends on the product of "power output intensity" and "duration", We can compare and analyze the energy consumption of two starting methods:

正确逻辑：起步瞬间，深踩一点油门（但无需地板油，油门深度控制在20%-30%即可），利用电机强大的低扭特性瞬间克服静摩擦力和惯性阻力，让车辆快速从静止状态切换到运动状态。在这一过程中，电机的瞬时功率确实较高，但由于阻力峰值持续时间极短（通常仅为1-2秒），因此总能耗反而较低。这就像我们推沉重的箱子，瞬间用力将箱子推动，后续只需较小的力就能维持其运动；而如果一直用小力慢慢推，可能始终无法推动，或者需要持续消耗大量体力。

Correct logic: At the moment of starting, step on the accelerator a little harder (but no need to floor it, the accelerator depth can be controlled at 20%-30%), and use the motor's powerful low-torque characteristic to instantly overcome static friction and inertial resistance, allowing the vehicle to quickly switch from a static state to a moving state, In this process, the instantaneous power of the motor is indeed high, but because the peak resistance duration is extremely short (usually only 1-2 seconds), the total energy consumption is relatively low, This is like pushing a heavy box: pushing the box instantly with force, and then only a small force is needed to maintain its movement; if you keep pushing slowly with a small force, you may never push it, or you need to continuously consume a lot of physical strength,

错误逻辑：如果像蜗牛一样慢慢踩油门“蠕行”，电机输出的扭矩刚好只能勉强对抗静摩擦力，车辆始终处于“动与不动”的临界边缘。此时，电机需要持续输出功率来维持这种临界状态，导致电流长时间维持在一个尴尬的“低效区间”。从电机的工作效率曲线来看，当电机处于低扭矩、低转速的临界工作状态时，效率通常不足50%，远低于正常行驶时80%以上的高效区间。这种持续的低效工作，会导致大量电能以热能的形式损耗，最终造成总能耗大幅增加。

Wrong logic: If you step on the accelerator slowly to "creep" like a snail, the torque output by the motor is just barely enough to resist static friction, and the vehicle is always on the critical edge of "moving or not moving", At this time, the motor needs to continuously output power to maintain this critical state, resulting in the current being maintained in an awkward "inefficient range" for a long time, From the perspective of the motor's working efficiency curve, when the motor is in the critical working state of low torque and low speed, the efficiency is usually less than 50%, which is much lower than the high-efficiency range of more than 80% during normal driving, This continuous inefficient work will cause a lot of electrical energy to be lost in the form of heat, eventually leading to a significant increase in total energy consumption,

结合大量实际测试数据来看，采用“蠕行”起步方式的车辆，在起步后前1公里的平均电耗，比采用“果断起步”方式的车辆高出15%-20%。以一台标称续航500公里的新能源汽车为例，仅起步方式的差异，全程就能导致近50公里的续航差距。

Combined with a large number of actual test data, the average power consumption of vehicles using the "creeping" starting method in the first 1 kilometer after starting is 15%-20% higher than that of vehicles using the "decisive starting" method, Taking a new energy vehicle with a nominal battery life of 500 kilometers as an example, the difference in starting methods alone can lead to a battery life gap of nearly 50 kilometers throughout the journey,

因此，真正科学的省电起步方式是：起步时果断踩下油门（油门深度控制在20%-30%），让车速在短时间内迅速提升到20-30km/h，然后松开油门利用车辆惯性滑行。这种“脉冲式”起步方式，能够最大限度地利用电机的低扭优势，避开低效工作区间，从而实现真正的省电效果。

Therefore, the real scientific and energy-saving starting method is: step on the accelerator decisively when starting (control the accelerator depth at 20%-30%), let the vehicle speed quickly increase to 20-30km/h in a short time, and then release the accelerator to glide using the vehicle's inertia, This "pulse-type" starting method can maximize the use of the motor's low-torque advantage, avoid the inefficient working range, and thus achieve the real energy-saving effect,

二、误区二：空调死守26度，忽视风量才是能耗元凶

Myth 2: Insisting on setting the air conditioner to 26 degrees, ignoring that air volume is the main culprit of energy consumption

在新能源汽车的空调使用场景中，“26度最省电”的说法流传最广。不少车主认为，26度是人体舒适温度区间，同时也是空调压缩机的高效工作温度，只要将温度设定在26度，就能实现空调系统的最低能耗。基于这一认知，很多车主在炎热天气下，会将空调温度固定在26度，然后为了快速降温，把风量开到最大档（5-6档），殊不知这种操作恰恰陷入了严重的能耗误区。

In the air conditioning usage scenarios of new energy vehicles, the statement that "26 degrees is the most energy-efficient" is the most widespread, Many car owners believe that 26 degrees is the human comfortable temperature range and also the efficient working temperature of the air conditioning compressor, As long as the temperature is set to 26 degrees, the minimum energy consumption of the air conditioning system can be achieved, Based on this cognition, many car owners will fix the air conditioning temperature at 26 degrees in hot weather, and then turn the air volume to the maximum gear (5-6 gears) to cool down quickly, Little do they know that this operation has fallen into a serious energy consumption misunderstanding,

要打破这一误区，我们首先需要明确空调系统的能耗构成。新能源汽车的空调系统主要由压缩机和鼓风机两大部分组成，其总能耗是压缩机能耗与鼓风机能耗的总和。单纯将温度设定为26度，并不能决定空调系统的总能耗，因为鼓风机的能耗占比往往被严重低估。

To break this misunderstanding, we first need to clarify the energy consumption composition of the air conditioning system, The air conditioning system of new energy vehicles is mainly composed of two parts: the compressor and the blower, Its total energy consumption is the sum of the compressor's energy consumption and the blower's energy consumption, Simply setting the temperature to 26 degrees cannot determine the total energy consumption of the air conditioning system, because the energy consumption ratio of the blower is often seriously underestimated,

从压缩机的工作原理来看，设定温度确实会影响其能耗。空调压缩机的核心作用是压缩制冷剂，通过制冷剂的循环实现车内热量的转移。当设定温度较低时（如18度），压缩机需要长时间高负荷运转，才能将车内温度降至设定值，能耗相对较高；而当设定温度为26度时，压缩机的负荷相对较小，能耗确实比低温设定时更低。这也是“26度省电”说法的由来，但这一说法只考虑了压缩机的能耗，忽略了鼓风机的能耗影响。

From the working principle of the compressor, the set temperature will indeed affect its energy consumption, The core function of the air conditioning compressor is to compress the refrigerant and realize the transfer of heat inside the car through the circulation of the refrigerant, When the set temperature is low (such as 18 degrees), the compressor needs to run at high load for a long time to reduce the temperature inside the car to the set value, and the energy consumption is relatively high; when the set temperature is 26 degrees, the load of the compressor is relatively small, and the energy consumption is indeed lower than that at low temperature settings, This is the origin of the statement that "26 degrees is energy-saving", but this statement only considers the energy consumption of the compressor and ignores the impact of the blower's energy consumption,

鼓风机是空调系统中被普遍忽视的“电耗子”。鼓风机的作用是将经过制冷或加热的空气吹入车内，其能耗与风量档位直接相关——风量越大，鼓风机电机的转速越高，做功越多，耗电量也就直线上升。根据实测数据，当空调风量从1档提升至6档时，鼓风机的能耗会增加3-4倍，其能耗占比甚至会超过压缩机，成为空调系统的主要能耗来源。

The blower is a generally ignored "power hog" in the air conditioning system, The function of the blower is to blow the cooled or heated air into the car, Its energy consumption is directly related to the air volume gear - the larger the air volume, the higher the speed of the blower motor, the more work it does, and the power consumption rises linearly, According to the actual test data, when the air conditioning air volume is increased from 1st gear to 6th gear, the energy consumption of the blower will increase by 3-4 times, and its energy consumption ratio may even exceed that of the compressor, becoming the main energy consumption source of the air conditioning system,

更关键的是，大风量会加速车内空气流动，形成强气流吹拂人体，让人在短时间内产生“凉爽”的体感错觉。这种错觉会让车主误以为“26度的制冷效果不足”，进而进一步调低温度（如降至24度以下），导致压缩机负荷增加，最终形成“大风量+低温度”的双重高能耗模式，让空调系统的总能耗大幅飙升。

More importantly, the large air volume will accelerate the air flow inside the car, forming a strong air current blowing the human body, making people have an illusion of "coolness" in a short time, This illusion will make car owners mistakenly think that "the cooling effect at 26 degrees is insufficient", and then further lower the temperature (such as below 24 degrees), leading to an increase in compressor load, and finally forming a dual high-energy consumption mode of "large air volume + low temperature", which makes the total energy consumption of the air conditioning system soar sharply,

基于空调系统的能耗构成和工作原理，我们总结出真正科学的省电空调使用方法，核心原则是“温度适中+小风量+合理循环模式”，具体可分为以下三个要点：

Based on the energy consumption composition and working principle of the air conditioning system, we summarize the real scientific and energy-saving air conditioning usage methods, The core principle is "moderate temperature + small air volume + reasonable circulation mode", which can be specifically divided into the following three points:

1, 温度与风量的合理搭配：放弃“死守26度”的执念，采用“温度稍低+小风量”的组合模式。例如，将温度设定为24-25度，风量控制在2-3档。虽然此时压缩机的能耗比26度设定时略高，但鼓风机的能耗会大幅降低，综合能耗通常比“26度+5-6档风量”低20%-30%。同时，小风量模式下没有明显的气流噪音，体感也更为舒适，避免了强气流对人体的刺激。

1, Reasonable matching of temperature and air volume: Give up the obsession of "insisting on 26 degrees" and adopt the combination mode of "slightly lower temperature + small air volume", For example, set the temperature to 24-25 degrees and control the air volume at 2-3 gears, Although the energy consumption of the compressor is slightly higher than that at 26 degrees at this time, the energy consumption of the blower will be greatly reduced, and the comprehensive energy consumption is usually 20%-30% lower than that of "26 degrees + 5-6 gears of air volume", At the same time, there is no obvious air flow noise in the small air volume mode, and the body feeling is more comfortable, avoiding the stimulation of strong air flow to the human body,

2, 善用内循环模式：内循环模式的核心优势是利用车内已冷却的空气进行循环制冷，热交换效率远高于外循环模式（外循环需要持续冷却车外高温空气）。正确的使用方法是：刚上车时，由于车内温度较高，先开启外循环模式，快速排出车内的高温空气；待车内温度降至舒适区间后（通常为5-10分钟），立即切换至内循环模式。这样可以有效降低压缩机的工作负荷，减少能耗。实测数据显示，内循环模式下空调系统的能耗比外循环模式低35%-40%。

2, Make good use of the internal circulation mode: The core advantage of the internal circulation mode is to use the cooled air inside the car for circulating refrigeration, and the heat exchange efficiency is much higher than that of the external circulation mode (external circulation needs to continuously cool the high-temperature air outside the car), The correct usage method is: when getting in the car just now, due to the high temperature inside the car, first turn on the external circulation mode to quickly discharge the high-temperature air inside the car; after the temperature inside the car drops to the comfortable range (usually 5-10 minutes), immediately switch to the internal circulation mode, This can effectively reduce the working load of the compressor and reduce energy consumption, The actual test data shows that the energy consumption of the air conditioning system in the internal circulation mode is 35%-40% lower than that in the external circulation mode,

3, 开启空调ECO模式：目前市面上绝大多数新能源汽车的空调系统都配备了ECO模式。开启ECO模式后，车辆控制系统会自动限制空调压缩机的最大输出功率，优化压缩机的工作曲线，避免其长时间高负荷运转。虽然ECO模式下的降温速度会比标准模式慢一些，但能耗可以降低15%-20%，非常适合在车辆行驶过程中持续使用。需要注意的是，在车辆静止、车内温度极高的情况下，可先关闭ECO模式快速降温，待温度下降后再开启。

3, Turn on the air conditioning ECO mode: At present, the air conditioning systems of most new energy vehicles on the market are equipped with ECO mode, After turning on the ECO mode, the vehicle control system will automatically limit the maximum output power of the air conditioning compressor, optimize the working curve of the compressor, and avoid its long-term high-load operation, Although the cooling speed in ECO mode is slower than that in standard mode, the energy consumption can be reduced by 15%-20%, which is very suitable for continuous use during vehicle driving, It should be noted that when the vehicle is stationary and the temperature inside the car is extremely high, you can first turn off the ECO mode to cool down quickly, and then turn it on after the temperature drops,

三、误区三：下坡“放空挡”或“松油门滑行”，浪费免费续航

Myth 3: Shifting to neutral or "coasting with the accelerator released" when going downhill, wasting free battery life

“下坡不踩油门，让车自己滑下去，不用消耗电能，肯定最省电。”这一认知源自传统燃油车的驾驶经验，在新能源汽车时代，却成为了典型的续航浪费行为。不少从燃油车转型为新能源汽车的车主，会习惯性地在 downhill 时挂空挡或松开油门滑行，认为这样能节省电能，却殊不知自己正在把白送的“续航”白白扔出窗外。

"When going downhill, don't step on the accelerator, let the car slide down by itself, no need to consume electrical energy, it must be the most energy-saving," This cognition comes from the driving experience of traditional fuel vehicles, In the era of new energy vehicles, it has become a typical behavior of wasting battery life, Many car owners who have switched from fuel vehicles to new energy vehicles will habitually shift to neutral or release the accelerator to coast when going downhill, thinking that this can save electrical energy, but they don't know that they are throwing away the free "battery life" for nothing,

要理解这一误区，核心在于区分燃油车与新能源汽车的下坡能量管理逻辑。燃油车的发动机在不喷油的情况下，会因车轮带动而高速运转，产生一定的阻力（即发动机制动）。为了减少这种阻力带来的动力损耗，燃油车在下坡时放空挡滑行，让车辆依靠惯性行驶，确实能降低燃油消耗。但新能源汽车的电机与燃油发动机的工作原理完全不同，其下坡时的能量管理逻辑也存在本质差异。

To understand this misunderstanding, the core is to distinguish the downhill energy management logic between fuel vehicles and new energy vehicles, When the engine of a fuel vehicle is not injecting fuel, it will run at high speed driven by the wheels, generating a certain resistance (i,e,, engine braking), To reduce the power loss caused by this resistance, shifting the fuel vehicle to neutral and coasting when going downhill, allowing the vehicle to drive by inertia, can indeed reduce fuel consumption, However, the working principle of the motor of new energy vehicles is completely different from that of fuel engines, and there are essential differences in their energy management logic when going downhill,

新能源汽车的电机具有“可逆性”特征：当电机通电时，它是一个电动机，将电能转化为机械能驱动车辆行驶；当电机不通电时，它可以作为一个发电机，将车辆的动能或重力势能转化为电能储存回电池中，这一过程就是新能源汽车的核心节能技术——动能回收。

The motor of new energy vehicles has the characteristic of "reversibility": when the motor is energized, it is an electric motor that converts electrical energy into mechanical energy to drive the vehicle; when the motor is de-energized, it can act as a generator to convert the vehicle's kinetic energy or gravitational potential energy into electrical energy and store it back in the battery, This process is the core energy-saving technology of new energy vehicles - kinetic energy recovery,

当下坡时，车辆在重力作用下会自然加速，此时车辆具有大量的重力势能。如果车主选择挂空挡或进入“滑行模式”（部分车型松开油门后会自动进入滑行模式，切断电机与车轮的连接），就相当于切断了电机与车轮的传动关系，电机无法被车轮带动发电，原本可以回收的重力势能就会以惯性的形式白白消耗掉。更糟糕的是，为了控制车速，避免车辆因持续加速而失控，车主需要频繁踩下刹车，将宝贵的动能转化为刹车片的热能散发掉，造成双重能量浪费。

When going downhill, the vehicle will naturally accelerate under the action of gravity, and at this time the vehicle has a lot of gravitational potential energy, If the car owner chooses to shift to neutral or enter the "coasting mode" (some models will automatically enter the coasting mode after releasing the accelerator, cutting off the connection between the motor and the wheels), it is equivalent to cutting off the transmission relationship between the motor and the wheels, The motor cannot be driven by the wheels to generate electricity, and the gravitational potential energy that could have been recovered will be wasted in the form of inertia, What's worse, to control the vehicle speed and avoid the vehicle from getting out of control due to continuous acceleration, the car owner needs to step on the brake frequently, converting the precious kinetic energy into heat energy of the brake pads and dissipating it, resulting in double energy waste,

相反，正确的下坡操作不仅不会消耗电能，还能“免费”回收能量，增加车辆续航。根据不同的坡度和车速，我们可以将正确的下坡省电方法分为两种场景：

On the contrary, the correct downhill operation will not only not consume electrical energy, but also "freely" recover energy and increase vehicle battery life, According to different slopes and vehicle speeds, we can divide the correct downhill energy-saving methods into two scenarios:

1, 平缓下坡场景：当下坡坡度较缓（如城市道路的缓坡），车辆加速不明显时，可轻踩油门（油门深度控制在10%左右），让车辆进入“弱动能回收”状态。此时，电机与车轮保持连接，车辆依靠重力自然滑行加速，电机在车轮的带动下缓慢发电，功率表会显示为负数（代表能量回收）。这种方式既能利用重力势能回收电能，又能维持车辆的稳定速度，无需频繁刹车，实现能量的最大化利用。

1, Gentle downhill scenario: When the downhill slope is gentle (such as a gentle slope on urban roads) and the vehicle acceleration is not obvious, you can step on the accelerator lightly (the accelerator depth is controlled at about 10%) to let the vehicle enter the "weak kinetic energy recovery" state, At this time, the motor is connected to the wheels, the vehicle slides and accelerates naturally by gravity, the motor generates electricity slowly driven by the wheels, and the power meter will display a negative number (representing energy recovery), This method can not only recover electrical energy by using gravitational potential energy, but also maintain a stable speed of the vehicle, without frequent braking, realizing the maximum utilization of energy,

2, 陡峭下坡场景：当下坡坡度较陡（如山区公路的长下坡），车辆加速明显时，应松开油门，让车辆进入“强动能回收”状态。此时，电机的发电功率会增大，产生较大的制动力，减缓车辆的加速趋势，甚至可以让车辆保持匀速行驶。在这种状态下，能量回收效率最高，根据实测数据，长下坡路段的动能回收量可让车辆续航增加5-10公里（具体取决于坡度和下坡长度）。需要注意的是，强动能回收会产生明显的“拖拽感”，初次使用的车主需要适应，但无需担心车辆失控，因为动能回收的制动力是由车辆控制系统精准调控的，不会超过车辆的制动极限。

2, Steep downhill scenario: When the downhill slope is steep (such as a long downhill on a mountain road) and the vehicle acceleration is obvious, you should release the accelerator to let the vehicle enter the "strong kinetic energy recovery" state, At this time, the power generation power of the motor will increase, generating a large braking force, slowing down the acceleration trend of the vehicle, and even allowing the vehicle to maintain a constant speed, In this state, the energy recovery efficiency is the highest, According to the actual test data, the amount of kinetic energy recovered on long downhill sections can increase the vehicle's battery life by 5-10 kilometers (depending on the slope and downhill length), It should be noted that strong kinetic energy recovery will produce an obvious "drag feeling", which requires adaptation for first-time users, but there is no need to worry about vehicle loss of control, because the braking force of kinetic energy recovery is accurately regulated by the vehicle control system and will not exceed the vehicle's braking limit,

这里需要特别强调的是：在安全范围内，下坡时的车速越快，动能回收的效率越高。因为电机的发电功率与转速正相关，车速越高，车轮带动电机的转速越高，发电功率也就越大，回收的能量也就越多。但这必须建立在安全驾驶的前提下，严禁为了追求能量回收而超速行驶。

It should be emphasized here that within the safe range, the faster the vehicle speed when going downhill, the higher the efficiency of kinetic energy recovery, Because the power generation power of the motor is positively related to the speed, the higher the vehicle speed, the higher the speed of the motor driven by the wheels, the higher the power generation power, and the more energy recovered, But this must be based on safe driving, and it is strictly prohibited to overspeed for the purpose of pursuing energy recovery,

四、误区四：为省电不开“热管理”，电池“中暑”“感冒”更费电

Myth 4: Not turning on "thermal management" to save electricity, battery "heatstroke" and "cold" are more power-consuming

“电池预加热、预冷都需要耗电，我干脆不开，等上车后再开空调调节温度，这样能省不少电。”这是很多新能源车主的常见做法，尤其是在春秋季节温度适宜时，这种认知更为普遍。但实际上，这种“捡了芝麻丢西瓜”的操作，会让电池因工作温度不适而进入低效区间，最终导致续航大幅缩水，反而得不偿失。

"Battery pre-heating and pre-cooling both need to consume electricity, I simply don't turn them on, I'll turn on the air conditioner to adjust the temperature after getting in the car, This can save a lot of electricity," This is a common practice among many new energy vehicle owners, especially when the temperature is suitable in spring and autumn, this cognition is more common, But in fact, this kind of operation of "picking up sesame seeds and losing watermelons" will make the battery enter an inefficient range due to inappropriate working temperature, and eventually lead to a significant reduction in battery life, which is not worth the loss,

新能源汽车的核心动力来源是锂电池，而锂电池对工作温度有着严格的要求——其最佳工作温度区间为25℃-35℃。在这个温度区间内，锂电池的内阻最小、充放电效率最高，能够充分发挥其能量输出能力；一旦温度偏离这个区间，无论是过高（中暑）还是过低（感冒），锂电池的性能都会急剧下降，电耗大幅增加。

The core power source of new energy vehicles is lithium batteries, and lithium batteries have strict requirements on working temperature - their optimal working temperature range is 25℃-35℃, Within this temperature range, the lithium battery has the smallest internal resistance and the highest charge-discharge efficiency, and can give full play to its energy output capacity; once the temperature deviates from this range, whether it is too high (heatstroke) or too low (cold), the performance of the lithium battery will drop sharply and the power consumption will increase significantly,

我们先来看高温场景的影响。在夏季高温天气下，新能源汽车长时间停放在露天停车场，车内和电池包的温度会快速升高，甚至可能达到50℃以上。此时，如果车主直接启动车辆行驶，电池会在高温环境下工作，导致两大问题：一是电池内阻增大，放电效率降低，为了维持车辆的动力输出，电机需要输出更大的电流，从而导致电耗飙升；二是高温会加速电池内部的化学反应，车辆控制系统为了保护电池安全，会自动限制电机的最大输出功率（即进入“功率限制模式”），车辆动力下降，同时空调压缩机需要高负荷运转来为座舱和电池降温，进一步增加能耗。实测数据显示，在50℃高温环境下，新能源汽车的续航会比25℃常温环境下减少30%-40%。

Let's first look at the impact of high-temperature scenarios, In high-temperature weather in summer, new energy vehicles parked in open-air parking lots for a long time will have the temperature inside the car and the battery pack rise rapidly, even possibly exceeding 50℃, At this time, if the car owner directly starts the vehicle to drive, the battery will work in a high-temperature environment, leading to two major problems: first, the internal resistance of the battery increases, and the discharge efficiency decreases, To maintain the vehicle's power output, the motor needs to output a larger current, resulting in a surge in power consumption; second, high temperature will accelerate the chemical reactions inside the battery, To protect the battery safety, the vehicle control system will automatically limit the maximum output power of the motor (that is, enter the "power limit mode"), the vehicle power decreases, and at the same time, the air conditioning compressor needs to run at high load to cool the cockpit and battery, further increasing energy consumption, The actual test data shows that in a high-temperature environment of 50℃, the battery life of new energy vehicles will be reduced by 30%-40% compared with that in a normal temperature environment of 25℃,

再来看低温场景的影响。在冬季低温环境下（如零下10℃以下），锂电池的活性会显著降低，内部的锂离子迁移速度变慢，导致电池的输出电压降低。为了维持车辆的正常动力，电机需要输出更大的电流，这会让电耗急剧增加。同时，低温会导致电池的可用容量减少，原本标称500公里的续航，在低温环境下可能只能跑250公里左右，续航直接腰斩。更重要的是，低温环境下电池的充电效率也会大幅降低，延长充电时间，进一步影响用车体验。

Let's look at the impact of low-temperature scenarios, In low-temperature environments in winter (such as below -10℃), the activity of lithium batteries will decrease significantly, and the migration speed of lithium ions inside will slow down, leading to a decrease in the output voltage of the battery, To maintain the normal power of the vehicle, the motor needs to output a larger current, which will cause a sharp increase in power consumption, At the same time, low temperature will reduce the available capacity of the battery, The original nominal battery life of 500 kilometers may only be able to run about 250 kilometers in a low-temperature environment, and the battery life is directly halved, More importantly, the charging efficiency of the battery will also be greatly reduced in a low-temperature environment, extending the charging time and further affecting the driving experience,

针对电池的温度特性，新能源汽车厂商都配备了专业的电池热管理系统，包括电池预加热、预冷功能。这一系统的核心作用，就是在车辆行驶前，将电池温度调节到最佳工作区间，确保电池以最高效率工作。而很多车主为了节省少量的预热/预冷电能，放弃使用这一功能，最终导致电池在低效区间工作，造成更大的能耗损失。

In response to the temperature characteristics of the battery, new energy vehicle manufacturers are equipped with professional battery thermal management systems, including battery pre-heating and pre-cooling functions, The core function of this system is to adjust the battery temperature to the optimal working range before the vehicle is driven, ensuring that the battery works at the highest efficiency, However, many car owners give up using this function to save a small amount of pre-heating/pre-cooling electrical energy, which eventually causes the battery to work in an inefficient range, resulting in greater energy consumption losses,

真正科学的省电秘籍，是充分利用充电桩的电能，在车辆充电时完成电池的预加热或预冷，让电池以最佳状态出发。具体操作方法如下：

The real scientific energy-saving tip is to make full use of the electrical energy of the charging pile to complete the pre-heating or pre-cooling of the battery when the vehicle is charging, so that the battery can start in the best state, The specific operation methods are as follows:

1, 夏季高温场景：在车辆充电时，通过手机APP远程开启“座舱预冷”和“电池降温”功能。此时车辆使用的是充电桩的电网电能，而非电池自身的电能，能够在不消耗续航的前提下，将座舱温度和电池温度降至最佳区间。待充电完成后，车辆已处于凉爽舒适的状态，行驶过程中空调只需维持小风量即可，大幅降低空调系统的能耗。

1, Summer high-temperature scenario: When the vehicle is charging, remotely turn on the "cockpit pre-cooling" and "battery cooling" functions through the mobile phone APP, At this time, the vehicle uses the grid electrical energy of the charging pile instead of the battery's own electrical energy, which can reduce the cockpit temperature and battery temperature to the optimal range without consuming battery life, After the charging is completed, the vehicle is already in a cool and comfortable state, and the air conditioner only needs to maintain a small air volume during driving, which greatly reduces the energy consumption of the air conditioning system,

2, 冬季低温场景：充电时，通过手机APP开启“电池预热”功能。车辆会利用充电桩的电能，将电池温度加热到20℃以上（接近最佳工作温度）。预热完成后，电池的活性得到充分恢复，放电效率大幅提升，续航可提升20%-30%。同时，也可以同步开启“座舱预热”功能，上车后无需等待即可享受温暖的驾乘环境，避免了行驶过程中空调高负荷制热消耗电能。

2, Winter low-temperature scenario: When charging, turn on the "battery pre-heating" function through the mobile phone APP, The vehicle will use the electrical energy of the charging pile to heat the battery temperature to above 20℃ (close to the optimal working temperature), After the pre-heating is completed, the activity of the battery is fully restored, the discharge efficiency is greatly improved, and the battery life can be increased by 20%-30%, At the same time, you can also turn on the "cockpit pre-heating" function synchronously, and you can enjoy a warm driving environment immediately after getting in the car, avoiding the high-load heating of the air conditioner during driving that consumes electrical energy,

简单来说，只要车辆插着充电桩，就可以放心大胆地使用空调和电池热管理功能，因为此时消耗的是“免费”的电网电能，而非电池的续航电能。这种方式看似“耗电”，实则是最划算的省电策略，能够最大限度地发挥电池的续航潜力。

Simply put, as long as the vehicle is connected to the charging pile, you can safely use the air conditioning and battery thermal management functions, because the electrical energy consumed at this time is the "free" grid electrical energy, not the battery's cruising electrical energy, This way seems "power-consuming", but it is actually the most cost-effective energy-saving strategy, which can maximize the battery life potential of the battery,

五、误区五：胎压打得过高，伤胎又费电

Myth 5: Inflating the tire pressure too high, damaging the tires and consuming more power

“胎压越高，轮胎与地面的接触面积越小，滚动阻力就越小，肯定越省电。我把胎压打到3,0bar，甚至更高，续航就能明显提升。”这一认知基于“滚动阻力与接触面积正相关”的理论逻辑，但在实际用车场景中，却忽略了路面平整度和车辆行驶稳定性的影响，最终导致“伤胎又费电”的双重后果。

"The higher the tire pressure, the smaller the contact area between the tire and the ground, the smaller the rolling resistance, and the more energy-saving it must be, I inflate the tire pressure to 3,0bar or even higher, and the battery life can be significantly improved," This cognition is based on the theoretical logic that "rolling resistance is positively related to contact area", but in actual driving scenarios, it ignores the impact of road flatness and vehicle driving stability, and ultimately leads to the double consequences of "damaging the tires and consuming more power",

从理论上讲，在绝对平整的路面上，提高胎压确实可以减小轮胎的接地面积，降低滚动阻力，从而减少车辆行驶过程中的能耗。但在实际路况中，无论是城市道路还是高速公路，路面都存在一定的颠簸和坑洼，绝对平整的路面几乎不存在。此时，过高的胎压会让轮胎的弹性大幅下降，无法有效吸收路面的颠簸，反而会导致车辆行驶过程中的能量损耗增加。

Theoretically, on an absolutely flat road, increasing the tire pressure can indeed reduce the contact area of the tire, reduce rolling resistance, and thus reduce energy consumption during vehicle driving, But in actual road conditions, whether it is urban roads or highways, the road surface has certain bumps and potholes, and an absolutely flat road surface almost does not exist, At this time, the excessively high tire pressure will greatly reduce the elasticity of the tire, making it unable to effectively absorb the bumps of the road surface, and instead will lead to an increase in energy loss during vehicle driving,

具体来看，过高胎压的负面影响主要体现在三个方面：一是轮胎接地面积过小，抓地力大幅下降，车辆在行驶过程中容易出现打滑现象，尤其是在雨天或湿滑路面上，制动距离会显著延长，存在严重的安全隐患；二是轮胎弹性不足，遇到路面坑洼时，会像皮球一样产生“弹跳”现象，车轮在瞬间失去抓地力，车辆会出现短暂的失控趋势，车主需要重新加速调整方向，这一过程会造成大量的能量浪费；三是过高的胎压会导致轮胎磨损不均匀，轮胎中间部位的磨损速度会远超两侧，大幅缩短轮胎的使用寿命，增加用车成本。

Specifically, the negative impacts of excessively high tire pressure are mainly reflected in three aspects: first, the tire contact area is too small, the grip is greatly reduced, and the vehicle is prone to slipping during driving, especially on rainy or slippery roads, the braking distance will be significantly extended, posing a serious safety hazard; second, the tire elasticity is insufficient, and when encountering road potholes

从能耗测试数据来看，当胎压超过厂家推荐值0,5bar以上时，车辆在城市颠簸路面上的电耗会增加10%-15%。以一台标称续航500公里的新能源汽车为例，全程电耗增加15%就意味着续航减少75公里，反而得不偿失。

From the energy consumption test data, when the tire pressure exceeds the manufacturer's recommended value by more than 0,5bar, the power consumption of the vehicle on urban bumpy roads will increase by 10%-15%, Taking a new energy vehicle with a nominal battery life of 500 kilometers as an example, an increase of 15% in full-range power consumption means a reduction of 75 kilometers in battery life, which is not worth the loss,

因此，真正科学的省电胎压，是严格按照车辆厂家的推荐值充气。厂家的推荐胎压值（通常标注在车辆B柱铭牌或油箱盖内侧）是综合考虑了车辆的行驶稳定性、舒适性、安全性和能耗的最佳平衡点，通常在2,5-2,8bar之间（具体数值因车型而异）。在这个胎压范围内，轮胎既能保证足够小的滚动阻力，又能具备良好的弹性和抓地力，能够在确保安全的前提下，实现最佳的能耗表现。

Therefore, the real scientific and energy-saving tire pressure is to inflate strictly according to the vehicle manufacturer's recommended value, The manufacturer's recommended tire pressure value (usually marked on the vehicle's B-pillar nameplate or inside the fuel tank cap) is the best balance that comprehensively considers the vehicle's driving stability, comfort, safety and energy consumption, usually between 2,5-2,8bar (the specific value varies by model), Within this tire pressure range, the tire can not only ensure a sufficiently small rolling resistance, but also have good elasticity and grip, and can achieve the best energy consumption performance on the premise of ensuring safety,

需要特别提醒的是，胎压会随温度变化而变化，夏季高温时胎压会升高，冬季低温时胎压会降低。车主应定期检查胎压（建议每月检查一次），根据季节温度变化适当调整，确保胎压始终维持在厂家推荐的合理范围内。

It should be specially reminded that the tire pressure will change with temperature, The tire pressure will increase in high temperature in summer and decrease in low temperature in winter, Car owners should check the tire pressure regularly (it is recommended to check once a month) and adjust it appropriately according to seasonal temperature changes to ensure that the tire pressure is always maintained within the reasonable range recommended by the manufacturer,

六、真正的省电：顺势而为，顺应物理规律与车辆逻辑

VI, Real energy saving: Go with the flow, comply with physical laws and vehicle logic

通过对以上5个伪省电习惯的深度解析，我们可以发现一个核心规律：真正的新能源汽车省电之道，并非是通过极端操作刻意压低电耗表显数值，而是顺应物理规律，遵循车辆的核心工作逻辑，让电机、电池等核心部件始终工作在高效区间。那些看似“精打细算”的省电操作，往往违背了基本的物理原理和车辆设计逻辑，最终导致续航缩水。

Through the in-depth analysis of the above 5 false energy-saving habits, we can find a core law: the real way to save electricity for new energy vehicles is not to deliberately lower the displayed value of power consumption through extreme operations, but to comply with physical laws and the core working logic of the vehicle, so that core components such as motors and batteries always work in the efficient range, Those seemingly "careful" energy-saving operations often violate basic physical principles and vehicle design logic, and ultimately lead to reduced battery life,

总结来看，真正科学高效的用车习惯可以归纳为以下5点，帮助车主轻松实现续航最大化：

In summary, the real scientific and efficient car usage habits can be summarized into the following 5 points, helping car owners easily maximize battery life:

1, 起步果断不磨蹭：利用电机低扭瞬间爆发的特性，起步时果断踩下油门（20%-30%深度），快速将车速提升至20-30km/h后滑行，避开电机低效工作区间，减少起步能耗。

1, Decisive start without hesitation: Take advantage of the motor's characteristic of instant low-torque burst, step on the accelerator decisively when starting (20%-30% depth), quickly increase the vehicle speed to 20-30km/h and then glide, avoid the motor's inefficient working range, and reduce starting energy consumption,

2, 空调使用讲策略：放弃“死守26度”的执念，采用“24-25度温度+2-3档风量”的组合模式，高温时先开外循环排热再切内循环，日常开启空调ECO模式，实现空调系统的高效节能。

2, Strategic use of air conditioning: Give up the obsession of "insisting on 26 degrees", adopt the combination mode of "24-25 degrees temperature + 2-3 gears of air volume", first turn on external circulation to discharge heat in high temperature and then switch to internal circulation, and turn on the air conditioning ECO mode daily to achieve efficient energy saving of the air conditioning system,

3, 下坡带电巧回收：摒弃燃油车放空挡滑行的习惯，下坡时根据坡度轻踩油门或松开油门，利用动能回收系统将重力势能转化为电能，实现“免费续航”的同时，保证行驶安全。

3, Charged downhill with clever recovery: Abandon the habit of shifting fuel vehicles to neutral and coasting, When going downhill, step on the accelerator lightly or release the accelerator according to the slope, and use the kinetic energy recovery system to convert gravitational potential energy into electrical energy, realizing "free battery life" while ensuring driving safety,

4, 温控优先保高效：充电时充分利用充电桩电能，开启电池预加热/预冷和座舱预热/预冷功能，让电池和座舱提前进入最佳状态，避免行驶过程中因温度不适导致的高能耗。

4, Temperature control first to ensure high efficiency: Make full use of the charging pile's electrical energy when charging, turn on the battery pre-heating/pre-cooling and cockpit pre-heating/pre-cooling functions, so that the battery and cockpit enter the best state in advance, avoiding high energy consumption caused by inappropriate temperature during driving,

5, 胎压标准守规矩：严格按照厂家推荐值（2,5-2,8bar）充气，定期检查胎压并根据季节温度调整，保证轮胎的最佳滚动阻力和抓地力，兼顾安全与节能。

5, Standard tire pressure compliance: Inflate strictly according to the manufacturer's recommended value (2,5-2,8bar), check the tire pressure regularly and adjust according to seasonal temperature, ensure the best rolling resistance and grip of the tire, and balance safety and energy saving,
