具体地，第十五电阻R15的第一端接电源+V，第十五电阻R15的第二端以及第十六电阻R16的第一端共接构成触发信号接收单元1011的输入端，第十六电阻R16的第二端与第八电容C8的第二端共接构成触发信号接收单元1011的输出端。
以下结合工作原理对上述的充电管理模块101作进一步说明：
当充电管理模块101106接入辅助电源（包括电源485_3V3、电源VC_3V3以及VCCS）时，若触发信号接收单元1011仅接入电源485_3V3而未接入充电触发信号，则通过上拉电阻（第十五电阻R15）和下拉电阻（第十六电阻R16）分压后仅有低压辅助电源485_3V3从触发信号接收单元1011输出。若触发信号接收单元1011接入电源485_3V3同时接入充电触发信号，则在低压辅助电源485_3V3输出的同时，触发信号接收单元1011还将输出充电触发信号至充电管理芯片U2的充电触发端T1_ID，则充电管理芯片U2将控制电池检测模块102建立通信以获取电池的电池信息，并对电池信息进行安全验证，在验证电池信息满足安全充电条件时，充电管理芯片U2根据电池信息生成安全充电参数范围，以控制充电控制模块104根据安全充电参数范围对电池充电，且通过第十电阻R10、第十一电阻R11、第十二电阻R12以及第六电容C6组成的电压反馈单元1013和第十三电阻R13、第十四电阻R14以及第七电容C7的电流反馈单元1014获取电压反馈信号和电流反馈信号以验证参数设置的状态并进行修正；在充电过程中，充电管理芯片U2根据获取的电池温度生成电压调节信号和电流调节信号，并通过充电管理芯片U2的电压调节端VO_TRIM和电流调节端IO_TRIM将信号输出至充电调节模块103。
因此，本申请实施例提供的充电管理模块101，通过触发信号接收单元1011接入充电触发信号，通过充电管理单元1012对电池信息进行安全验证，在验证电池信息满足安全充电条件时控制充电控制模块104根据安全充电参数范围进行充电，从而安全有效地对电池充电，并在充电的同时有效识别出电池的真伪，保护了用户的安全和消费权益；同时，在充电过程中，充电管理单元1012根据电池温度生成电压调节信号和电流调节信号，从而最终使充电控制模块104调节功率输出以确保电池安全充电，提高电池的使用寿命。

以下结合工作原理对上述的电池检测模块102作进一步说明：在电池检测模块102接入电源VC_3V3时，若通信串口芯片IC的通信受控端接收到充电管理模块101输出的使能控制信号时，则第一双向二极管D1和第二双向二极管D2导通，电池检测模块102将通过第十九电阻R19的第二端连接的RS_485-接口和第二十电阻R20的第二端连接的RS_485+接口获取电池信息和电池温度，并通过通信串口芯片IC的第一输出端、第二输出端以及第三输出端将电池信息和温度信息输出至充电管理模块101。
