The invention discloses a battery temperature maintenance method and device. The method comprises the following steps: responding to an input operation of starting battery temperature maintenance; when the charging gun is to be inserted, a private message for starting battery temperature maintenance is sent to the charging private pile; when charging is finished, the charging target SOC of the vehicle, the current battery SOC and the power battery temperature are obtained; if the battery SOC is larger than the charging target SOC and the temperature of the power battery is smaller than or equal to the target temperature, temperature maintaining information is sent to the charging private pile, so that the charging private pile supplies power to the power battery for temperature maintaining; and disconnecting a main relay of the power battery. Therefore, on the premise of ensuring the electric quantity of the power battery, the temperature of the power battery can be maintained according to the actual battery temperature and the battery electric quantity.
本发明公开一种电池维温方法及装置,通过响应于开启电池维温的输入操作;在将插入充电枪时,向充电私桩发送开启电池维温的私有报文;在充电结束时,获取车辆的充电目标SOC、当前的电池SOC以及动力电池温度;若电池SOC大于充电目标SOC,且动力电池温度小于等于目标温度时,向充电私桩发送维温信息,使充电私桩供电给动力电池进行维温;断开动力电池的主继电器。如此,可以在确保在动力电池电量的前提下,根据实际电池温度以及电池电量对动力电池进行电池维温。
