The invention discloses a functional circuit for preventing power shortage of a battery, which is characterized in that one port of the input end of a DC-DC voltage converter is connected with a relay, the DC-DC voltage converter is connected with a two-way reset switch in parallel, one way of the two-way reset switch is connected with the relay in parallel, the output end of the way of the two-way reset switch is connected with the input end of the DC-DC voltage converter, and the other way of the two-way reset switch is connected with the output end of the DC-DC voltage converter. The other path of the double-path reset switch is used for BMS detection, the output end of the DC-DC voltage converter is connected with the BMS module, and the BMS module is further connected with the relay to control the relay to act. In the current design of energy storage products, the power consumed by a part of BMS (battery management system) is supplied by converting the battery voltage into constant 12V or 24V through a DCDC (voltage converter-DC to DC), although the BMS can achieve good battery management, when the battery is about to lack of power, the battery stops supplying power to the external load, and the power consumption of the battery is reduced. However, the electricity taken by the BMS is converted by the DC-DC voltage converter.
本发明公开了一种防止电池亏电的功能电路,其特征在于,包括DC‑DC电压转换器的输入端一端口与继电器连接,DC‑DC电压转换器与双路复位开关并联,所述双路复位开关一路与继电器并联,该路的输出端与DC‑DC电压转换器输入端连接,双路复位开关的另一路用于BMS检测,所述DC‑DC电压转换器的输出端与BMS模块连接,所述BMS模块还与继电器连接,控制继电器动作。在目前储能产品设计中,部分产品BMS(电池管理系统)所吃的电是由DCDC(电压转换器‑直流转直流)将电池电压转换恒定12V或者24V供给,虽然BMS可以做到很好的电池管理,在电池快要亏电时候,停止电池给外界负载供电,但是由于BMS所吃的电是由DC‑DC电压转换器转换而来。
