The invention relates to a power battery safety monitoring all-in-one low-voltage power supply and lithium battery energy complementing method, which is characterized in that an all-in-one controller is additionally arranged on a connecting circuit of a power battery, a power battery BMS (Battery Management System), a lithium battery and a lithium battery BMS, and the all-in-one controller is provided with a backup power supply and a DC/DC (Direct Current/Direct Current) converter for charging the lithium battery; low-voltage electricity is supplied to the power battery safety monitoring system through the lithium battery, power is supplied to a non-power battery through the DC/DC converter, and therefore the problems that due to the fact that the DC/DC converter is small in power and often needs to operate excessively, the fault rate is high, and monitoring cannot be achieved are solved; meanwhile, on the whole connecting circuit, the backup power supply of the all-in-one controller and the DC/DC converter used for charging the lithium battery are combined, low-power-consumption, high-stability and safe timing awakening power supply is achieved, energy supplementation is conducted on the lithium battery, and the whole circuit structure and the control method are simple and compact and high in safety and reliability.
本发明涉及一种动力电池安全监控多合一低压供电及锂电池补能方法,在动力电池、动力电池BMS、锂电池和锂电池BMS的连接电路上增设多合一控制器,多合一控制器设有备份电源和用于给锂电池充电的DC/DC转换器,通过锂电池给动力电池安全监控系统供低压电,而非动力电池本身通过DC/DC转换器来供电,从而避免DC/DC转换器因功率较小,经常需要超额运行工作,导致故障率高,无法监控的问题;同时,在整个连接电路上,结合多合一控制器的备份电源和用于给锂电池充电的DC/DC转换器,实现低功耗、高稳定和安全的定时唤醒供电,以及给锂电池进行补能,整个电路结构和控制方法简单紧凑,安全性和可靠性高。
