The invention relates to the field of battery charging, in particular to a battery charging and discharging control system which comprises a controller, a discharging circuit and a charging circuit, the discharging circuit and the charging circuit are respectively connected with the controller, one end of the discharging circuit is connected with a battery cathode, and the other end is connected with a load in series and then connected with a battery anode to form a discharging loop. One end of the charging circuit is connected with the cathode of the battery, and the other end is connected with the cathode of the charging module; the anode of the charging module is connected with the anode of the battery to form a charging loop. The system has the beneficial effects that the discharging circuit and the charging circuit are two loops, the discharging circuit can be disconnected in the charging process, and the load cannot be used, so that the problem that the battery is forbidden to discharge to the load in the charging process is solved, and the safety of the lithium battery electric vehicle in the charging process is ensured.
本发明涉及电池充电领域,尤其涉及一种电池充放电控制系统,包括控制器以及分别与控制器连接的放电电路、充电电路,所述放电电路一端连接电池负极,另一端串接负载后连接电池的正极构成放电回路,所述充电电路的一端连接电池负极,另一端连接充电模块的负极,充电模块的正极连接电池的正极构成充电回路。本发明的有益效果:放电电路、充电电路为两个回路,在充电过程中可以断开放电电路,负载由于无法使用,进而解决了在充电过程中禁止电池向负载放电的问题,保证了锂电池电动车在充电过程中的安全性。
