The invention relates to a battery heating method and device, a vehicle, a readable storage medium and a chip, and the method comprises the steps: obtaining the current battery discharge power of a vehicle battery, obtaining the demanded power of the vehicle, and closing a battery heating function when the environment temperature is lower than a preset threshold value and the current battery discharge power is greater than or equal to the demanded power. Starting a battery heating function under the condition that the environment temperature is lower than a preset threshold value and the current battery discharge power is lower than the required power; when the vehicle battery is heated, the environment temperature is considered, the size relation between the current battery discharging power of the vehicle and the required power of the vehicle is also considered, and the battery heating function is not started under the condition that the current battery discharging power is larger than or equal to the required power; the battery heating function is started under the condition that the current battery discharge power is smaller than the required power, namely the battery heating function is prevented from being started when the current battery discharge power can meet the required power, so that the power consumption of the vehicle is reduced.

    本公开涉及一种电池加热方法、装置、车辆、可读存储介质及芯片,包括获取车辆电池的当前电池放电功率,获取车辆的需求功率,在环境温度低于预定阈值,当前电池放电功率大于或等于需求功率的情况下,关闭电池加热功能,在环境温度低于预定阈值,当前电池放电功率小于需求功率的情况下,开启电池加热功能;在对车辆电池加热的时候,不仅考虑了环境温度,还考虑了车辆当前电池放电功率与车辆的需求功率之间的大小关系,当前电池放电功率大于或等于需求功率的情况下不开启电池加热功能,当前电池放电功率小于需求功率的情况下开启电池加热功能,即在当前电池放电功率能满足需求功率时避免开启电池加热功能,从而降低车辆功耗。
