The invention provides an electric vehicle high-voltage power storage battery inspection control method and device. The method comprises the steps that when a power management system BMS is in a dormant state, the BMS is awakened according to preset time intervals in multiple preset time periods, and the preset time interval in the later time period is larger than the preset time interval in the previous time period; and detecting a battery after the BMS is awakened, and judging a condition of the battery according to a detection result. In the invention, the battery management system is awakened regularly at the preset time intervals; and the battery management system detects the battery after being awakened, judges the condition of the battery according to a monitoring result and takes corresponding measures according to the condition of the battery so that a battery fault of the electric vehicle is effectively pre-judged, a problem of frequent faults during standing of the battery of the existing electric vehicle is solved, and a fault probability of the battery of the electric vehicle is reduced.
本发明提供一种电动汽车高压动力蓄电池巡检控制方法及装置,所述方法包括在电源管理系统BMS处于休眠状态时,在预设的多个时间段根据预设时间间隔分别唤醒BMS,后一时间段内的预设时间间隔大于前一时间段内的预设时间间隔;所述BMS被唤醒后对电池进行检测,根据检测结果判断电池状况。本发明通过预设时间间隔定时唤醒电池管理系统,电池管理系统被唤醒后对电池进行检测,根据监测结果判断电池状况,根据电池状况采取对应措施,有效地预判电动车电池故障,解决了现有电动汽车电池静置时经常出现故障的问题,降低电动车电池出现故障的概率。
