The invention discloses an intelligent battery charging and replacing system and method supporting battery charging and replacing after power outage, and a storage medium. The system comprises a direct current bus, an AC-DC module, a plurality of bidirectional DC-DC modules and a main control unit, wherein the AC-DC module is used for converting alternating current into direct current, all the bidirectional DC-DC modules are arranged in parallel through the direct current bus, and all the bidirectional DC-DC modules are connected in parallel through the main control unit; the bidirectional DC-DC module is used for charging/discharging the corresponding battery module; the main control unit respectively adjusts the charging/discharging action of each bidirectional DC-DC module so as to charge/discharge any battery module through the alternating current when the alternating current is normally supplied, and discharge any battery module and charge a specific battery module by using the discharge electric quantity when the alternating current is cut off. The system is advantaged in that any battery module can be discharged and the specific battery module can be charged by using the discharged electric quantity when the power grid is in the conditions of power failure, tripping and the like, so battery charging and replacing requirements of a user are met, the use experience is effectively improved, and the turnover rate of the battery module is improved.

    本发明公开了一种支持停电后充换电的智能充换电系统、方法和存储介质,该系统包括直流母线、AC‑DC模块、多个双向DC‑DC模块和一个主控单元,AC‑DC模块用于将交流电转化为直流电,所有双向DC‑DC模块通过直流母线呈并联设置,双向DC‑DC模块用于对对应的电池模块充电/放电;主控单元分别调整各个双向DC‑DC模块的充电/放电动作,以在交流电正常供电时,通过交流电对任意电池模块充电/放电,及在交流电断电时,通过对任意电池模块放电并利用放电电量对特定的电池模块充电;本发明能够在电网发生停电、跳闸等状况时,通过对任意电池模块放电并利用放电电量对特定的电池模块充电,以满足使用者的充换电需求,有效改善使用体验并提升电池模块的周转率。
