The invention relates to a vehicle power battery monitoring wake-up circuit and a control method, the vehicle power battery monitoring wake-up circuit comprises a storage battery, a manual switch, a first switch, a second switch, a first diode, a second diode, a monitoring system and a low-voltage power supply control module, the manual switch is a mechanical power supply main switch, the first switch is an electromagnetic relay, and the second switch is an electromagnetic relay; the storage battery and the monitoring system are connected and electrified through parallel connection of the manual switch and the first switch, and the first switch can be controlled by the low-voltage power supply control module to be switched on and switched off. As long as the low-voltage power supply control module identifies the key signal, the charging signal and the clock signal to perform logical operation and output the wake-up signal, the monitoring system can be powered and waken up, so that continuous monitoring for a period of time after the vehicle key is powered off and charged is realized, and the safety of the vehicle is improved.
本发明涉及一种车辆动力电池监控唤醒电路及控制方法,包括蓄电池、手动开关、第一开关、第二开关、第一二极管、第二二极管、监控系统和低压电源控制模块,手动开关为机械式电源总开关,第一开关为电磁式继电器,蓄电池与监控系统之间通过手动开关和第一开关的并联来实现连接通电,并且第一开关可由低压电源控制模块控制闭合与断开,由此本发明无论机械式电源总开关是否处于闭合状态,只要低压电源控制模块识别钥匙信号、充电信号、时钟信号进行逻辑运算输出唤醒信号,即可给监控系统供电和唤醒,从而实现车辆钥匙下电和充电结束后一段时间的连续监控,以提升车辆安全性。
