The invention relates to a system and method for recharging a low-voltage battery after dormancy of an electric vehicle. The system comprises a recharging condition editing module which is used for editing a basic condition that the low-voltage battery enters recharging and a stopping condition that the low-voltage battery quits recharging during charging, a monitoring module which is used for monitoring state information data of the recharging system, a judgment module which is used for judging whether the state information data, obtained by a detection module before the low-voltage battery is charged, of the recharging system meets the basic condition or not and judging whether the state information data, obtained by the monitoring module when the low-voltage battery is charged, of the recharging system meets the stopping condition or not, and a control module which is used for adjusting the DCDC to charge the low-voltage battery according to the result of the judgment module. The low-voltage battery in the electric vehicle in the dormant state is charged in good time, and the problem that the vehicle cannot be started due to feed of the low-voltage battery caused by long-time parking of the vehicle is solved.

    本发明涉及一种电动车休眠后对低压电池的补电系统及方法,包括:补电条件编辑模块,用于编辑低压电池进入补电的基本条件和充电时低压电池退出补电的中止条件;监测模块,用于监测该补电系统的状态信息数据;判断模块,用于判断检测模块在低压电池充电前获得的补电系统的状态信息数据是否满足基本条件和判断监测模块在低压电池充电时获得的补电系统的状态信息数据是否满足中止条件;控制模块,根据判断模块结果调整DCDC对低压电池的充电。本发明适时对处于休眠状态的电动车中的低压电池进行补电,避免车辆由于长时间停放而造成低压电池的馈电,无法启动车辆的问题。
