The invention discloses a control method and control system for gun insertion parking heat preservation of a power battery, and the method comprises the steps: the highest temperature and the lowest temperature of a battery are detected after charging is completed; according to the highest temperature and the lowest temperature, the whole vehicle is controlled to selectively enter a heat preservation state; and after the whole vehicle enters the heat preservation state, the charging mode of the battery is judged, wherein when the charging mode is judged to be a slow charging mode, the whole vehicle is controlled to selectively enter a slow charging heating mode, and when the charging mode is judged to be a fast charging mode, the whole vehicle is controlled to selectively enter a fast charging heating mode. According to the power battery gun insertion parking heat preservation control method, different heat preservation strategies are executed under different charging conditions, so that the electric quantity needed in the heat preservation process is saved, it is guaranteed to the maximum extent that when a driver starts the vehicle, the battery temperature is within a proper interval, the utilization rate of the electric quantity of the whole vehicle battery is increased, and the endurance mileage of the whole vehicle in a low-temperature environment is improved.
本申请公开了一种动力电池插枪驻车保温的控制方法和控制系统,包括:在充电完成后,检测电池的最高温度和最低温度;根据所述最高温度和所述最低温度控制整车选择性地进入保温状态:在进入所述保温状态后,判断所述电池的充电模式;其中在判定所述充电模式为慢充模式时,控制所述整车选择性地进入慢充加热模式,以及在判定所述充电模式为快充模式时,控制所述整车选择性地进入快充加热模式。本申请实施例的动力电池插枪驻车保温的控制方法,通过在不同充电情况下执行不同的保温策略,以节约保温过程中所需的电量,并最大程度地保证在驾驶员启动车辆时,电池温度处在适宜的区间内,提高整车电池电量的利用率,提高了整车在低温环境下的续航里程。
