The invention discloses a battery preheating control method for a new energy automobile and the energy automobile. The battery preheating control method comprises the steps of acquiring battery charging start time, specifically, detecting the real-time temperature of a battery of the new energy automobile, and calculating the heating time when the battery is heated to a fast charging working temperature according to the real-time temperature of the battery; and controlling a thermistor to heat the battery, specifically, obtaining the walking time of the new energy automobile arriving at a charging station, and starting the thermistor to heat the battery when the walking time is less than or equal to the heating time. According to the invention, the thermistor (PTC) is controlled in advance to preheat the battery in the using process of the new energy automobile, when the automobile arrives at the direct current charging pile, the battery core temperature of the battery reaches the normal working temperature, and the charging time of direct current fast charging can be effectively shortened.

    本申请公开了一种用于新能源汽车的电池预加热控制方法及能源汽车。电池预加热控制方法包括步骤:获取电池充电开始时间步骤,检测新能源汽车的电池实时温度,根据所述电池的实时温度计算该电池被加热至快充工作温度的加热时间;以及控制热敏电阻加热电池步骤,通过获取新能源汽车到达一充电站的行走时间,当所述行走时间小于或等于所述加热时间时开启热敏电阻加热电池。本申请通过在用于新能源汽车的使用过程中提前控制热敏电阻(PTC)对电池预加热,当车辆到达直流充电桩时电池的电芯温度已达到正常工作温度,可有效缩短直流快充的充电时间。
