The invention provides a storage battery charging method and system and a readable storage medium. The method comprises the steps that when TBOX detects that the SOC value of a storage battery is smaller than a first preset value and the time difference between the current moment and the moment when a charging request is initiated last time is larger than a preset time difference, the charging request is sent to a VCU; when receiving the charging request, the VCU detects whether a charging condition is met; when the charging condition is met, the VCU controls the high-voltage power battery tocharge the storage battery and feeds back charging start state information to the T-BOX; in the charging process, the VCU detects whether a charging quitting condition is met; and when the charging quitting condition is met, the VCU controls the high-voltage power battery to stop charging the storage battery and feeds back charging quitting state information to the T-BOX. According to the storagebattery charging method, when the charging condition is met, the storage battery is charged, and when the charging quitting condition is met, the charging of the storage battery is stopped, so that the flexible control of the charging of the storage battery is realized, and the situation of feeding of the storage battery is avoided as much as possible.

    本发明提供一种蓄电池补电方法、系统及可读存储介质。该方法包括:当T‑BOX检测到蓄电池的SOC值小于第一预设值,且当前时刻与上一次发起补电请求的时刻之间的时间差大于预设时间差时,发送补电请求至VCU;VCU收到补电请求时,检测是否满足进入补电条件;当满足进入补电条件时,VCU控制高压动力电池给蓄电池补电,并反馈补电开始状态信息给T‑BOX;在补电过程中,VCU检测是否满足退出补电条件;当满足退出补电条件时,VCU控制高压动力电池停止给蓄电池补电,并反馈退出补电状态信息给T‑BOX。通过本发明,在满足进入补电条件时,给蓄电池补电,在满足退出补电条件时,停止给蓄电池补电,实现对蓄电池补电的灵活控制,尽可能避免了蓄电池馈电的情况发生。
