The invention relates to an electric vehicle storage battery charging method and system, and the method comprises the steps: carrying out the charging of a storage battery through employing a pre-dormancy active charging sub-method before the network dormancy of an electric vehicle, and presetting a charging starting standard and a charging ending standard through the pre-dormancy active charging sub-method, the charging module is used for realizing active charging before network dormancy; and after the electric vehicle network is dormant, the storage battery is charged by adopting an after-dormancy active charging method, the after-dormancy active charging method adopts a timing awakening charging strategy, and the shortest charging duration is dynamically adjusted according to the current consumption of the vehicle. Compared with the prior art, the invention has the advantages of effective prevention of power shortage of the storage battery, high safety and the like.

    本发明涉及一种电动汽车蓄电池补电方法及系统,其中蓄电池补电方法包括:在电动汽车网络休眠前采用休眠前主动补电子方法对蓄电池进行补电,休眠前主动补电子方法预设开始补电标准和结束补电标准,用于实现网络休眠前的主动补电;在电动汽车网络休眠后采用休眠后主动补电子方法对蓄电池进行补电,休眠后主动补电子方法采用定时唤醒补电策略,并根据车辆的电流消耗动态调整最短补电时长。与现有技术相比,本发明具有有效防止蓄电池亏电、安全性高等优点。
