The invention relates to the technical field of battery management, and discloses a power battery short circuit detection protection system and method. The system comprises a first current sensor group, an event detection management module, a control module and an execution module which are connected in sequence. The current sensor group is used for acquiring the working current of the power battery; the event detection management module is used for setting relevant parameters of a battery short-circuit early warning event and judging whether the battery short-circuit early warning event exists or not; the control module is used for configuring the priority and the operation cycle of a current sampling task and judging whether a battery short-circuit fault event is established or not; and the execution module is used for executing short-circuit protection operation according to the short-circuit protection instruction. By judging the possibility of battery short circuit in advance and making corresponding response, the reliability of short circuit detection is improved, the battery short circuit fault can be found and processed in time, and the safety of a battery system is guaranteed.

    本发明涉及电池管理技术领域,公开了一种动力电池短路探测保护系统和方法。本发明系统包括依次连接的第一电流传感器组、事件探测管理模块、控制模块和执行模块。电流传感器组用于获取动力电池的工作电流;事件探测管理模块用于设置电池短路预警事件的相关参数,以及判断是否存在电池短路预警事件;控制模块用于配置电流采样任务的优先级和运行周期,以及判断电池短路故障事件是否成立;执行模块用于根据短路保护指令,执行短路保护操作。本发明通过提前判断电池短路的可能性并做出相应的应对,提高短路探测的可靠性,有利于及时发现并处理电池短路故障,保障了电池系统的安全。
