From the perspective of traditional fuel-powered cars, preheating before starting is crucial for increasing oil temperature and lubrication effectiveness. However, for pure electric cars, the situation is somewhat different. The primary driving force of electric cars comes from the battery, so there are some differences in the preheating process compared to fuel-powered cars.
To achieve the effect of preheating, pure electric cars do not need to be idled to warm up before starting. Instead, it is recommended to drive slowly at low speeds for a few kilometers when starting. This practice allows the power system and circuits of the electric car to gradually reach optimal conditions, ensuring the entire system operates smoothly.
Why do pure electric cars need preheating?
Preheating can increase the driving range of new energy vehicles. In winter, the coolant is stored inside the power battery pack. If the vehicle accelerates without preheating, the efficiency of the battery will be affected, resulting in a reduction in driving range. By preheating at low speeds first, the coolant gradually warms up, ensuring the battery operates normally and thereby extending the lifespan of the electric motor.
Additionally, if a pure electric car is started in winter without preheating and immediately accelerates or brakes sharply, these actions will greatly consume battery energy and damage the battery's lifespan. To reduce power consumption and prolong the battery's lifespan, it is strongly recommended to preheat at low speeds before accelerating gradually when using a pure electric car in winter.
