The invention relates to the technical field of electric vehicles, in particular to a battery safety protection management system, and solves the problem that in the prior art, when an MCU (Microprogrammed Control Unit) or a control program in a BMS (Battery Management System) fails, the disconnection of a battery cannot be controlled in time, and the battery is damaged. A battery safety protection management system comprises a battery management system provided with a safety protection circuit, and the battery management system comprises a battery pack, a charger, a main control circuit, a detection circuit and an external circuit which are connected with one another, and the main control circuit comprises a battery management control device and a charging and discharging main loop. And a group of serially connected charging power MOS tubes and a group of serially connected discharging power MOS tubes which are connected in parallel are arranged at the negative electrode end of the charging and discharging main loop. According to the system disclosed by the invention, the circuit structure of the system is set, and the on-off of the high-voltage battery can be controlled only through a hardware circuit, so that the safety problem existing when a control system fails in an existing system is solved, and the working safety of the battery can be better ensured.

    本发明涉及电动汽车技术领域,尤其涉及电池安全保护管理系统,解决了现有技术中当BMS控制系统中MCU或控制程序发生失效时,就可能出现不能及时控制电池断开的问题,而使电池发生损坏的问题。电池安全保护管理系统,包括设有安全保护电路的电池管理系统包括相互连接的电池组、充电机、主控电路、检测电路,外部电路,主控电路包括电池管理控制装置、充放电主回路,充放电主回路负极端设有并联连接的一组串联的充电功率MOS管和一组串联的放电功率MOS管。本发明该系统通过对系统电路结构进行设置,增加了仅通过硬件电路即可对高压电池的通断进行控制,解决了现有系统中当控制系统失效时存在的安全问题,能够更好地保证电池工作的安全性。
