The invention provides a battery heating method and a battery heating device.The battery heating method comprises the steps that according to the battery temperature of a vehicle, the environment temperature and a meteorological temperature model, the awakening moment before the battery temperature is lower than a first preset temperature threshold value is determined, and the meteorological temperature model describes the change relation between the environment temperature and the moment; and controlling to heat the battery at the wake-up moment. By means of the method, the battery can be heated when the battery temperature is about to be lower than the first preset temperature threshold value, the awakening frequency of the vehicle is reduced while battery failure is avoided, and therefore the heating power consumption of the battery is reduced.

    本申请提供了一种电池加热方法和电池加热装置,所述电池加热方法包括:根据车辆的电池温度、环境温度以及气象温度模型,确定电池温度低于第一预设温度阈值前的唤醒时刻,其中,所述气象温度模型描述了环境温度与时刻的变化关系;在所述唤醒时刻,控制对所述电池进行加热。通过本申请提供的方法,能够在电池温度即将低于第一预设温度阈值时加热电池,避免电池失效的同时减少车辆的唤醒次数,从而降低电池的加热功耗。
