The invention provides a vehicle-mounted battery heating control method and device, and the method comprises the steps: judging whether the battery temperature accords with a preset heating interval or not when a vehicle-mounted battery is charged; when the battery temperature accords with the preset heating interval, a battery heater is controlled to heat the vehicle-mounted battery to a first heating closing temperature; judging whether the charging current is smaller than a first current threshold value or not; and when the charging current is smaller than the first current threshold value, the battery heater is stopped from continuously heating the vehicle-mounted battery. Therefore, according to the method, the vehicle-mounted battery can be charged with the most ideal charging current, so that the charging efficiency is improved.

    本申请提供一种车载电池加热控制方法及装置,该方法包括:当车载电池充电时,判断电池温度是否符合预设加热区间;当电池温度符合预设加热区间时,控制电池加热器对车载电池加热至第一加热关闭温度;判断充电电流是否小于第一电流阈值;当充电电流小于第一电流阈值时,停止电池加热器对车载电池进行继续加热。可见,该方法能够以最理想的充电电流对车载电池进行充电,从而提高充电效率。
