The invention provides a power storage method and a power storage system for an electric vehicle. The electricity storage method comprises the steps that (A) when the electric vehicle is in a power-off state, the voltage of a low-voltage storage battery is detected; (B) executing the first judgment, if the result of the first judgment is yes, executing the second judgment, and skipping to the step (C); if the result of the second judgment is yes, starting a new detection period, taking the current moment as the initial moment of the new detection period, and skipping to the step (C); if the result of the second judgment is no, executing third judgment; if the result of the third judgment is yes, a power consumption abnormal fault is reported, and the power storage method is ended; if the result of the third judgment is no, skipping to the step (C); if the result of the first judgment is no, skipping to the step (A); (C) executing a charging operation, and charging the low-voltage storage battery until the voltage of the low-voltage storage battery reaches a preset charging voltage; and skipping to the step (A).

    本发明提供一种电动车的蓄电方法及蓄电系统。蓄电方法包括:步骤(A)当所述电动车处于下电状态时,检测低压蓄电池的电压;步骤(B)执行第一判断,若第一判断的结果为是,则执行第二判断,跳转到步骤(C);若第二判断的结果为是,则开始新的检测周期,将当前时刻作为新的检测周期的初始时刻,跳转到步骤(C);若第二判断的结果为否,则执行第三判断;若第三判断的结果为是,则报告耗电量异常故障,结束蓄电方法的步骤;若第三判断的结果为否,则跳转到步骤(C);若第一判断的结果为否,则跳转到步骤(A);步骤(C)执行充电操作,对低压蓄电池进行充电,直到低压蓄电池的电压达到预设充电电压;跳转到步骤(A)。
