According to the automatic charging method for the low-voltage storage battery of the electric vehicle, the charging starting condition is qualitatively judged through the open loop of the power-off storage days of the vehicle instead of a storage battery sensor, and the charging stopping condition is qualitatively judged through the open loop of the DCDC output current and the charging time whenthe storage battery is charged instead of the storage battery sensor; a storage battery charging management program is placed at the cloud end, parameter setting and parameter supplementing can be conveniently adjusted, the automatic storage battery charging function is achieved without using a storage battery sensor, the method is not limited to hardware, and the vehicle cost is reduced.

    本发明提出一种电动车低压蓄电池自动充电方法,不通过蓄电池传感器而是通过车辆下电存放天数开环定性判定开始充电条件,不通过蓄电池传感器而是通过蓄电池充电时DCDC输出电流和充电时间开环定性判断停止充电条件,蓄电池充电管理程序放在云端,可以方便的进行设置参数、补充参数的调整,本发明不使用蓄电池传感器实现蓄电池自动充电功能,不局限于硬件,降低了车辆成本。
