The invention discloses a storage battery safe charging circuit. The circuit comprises a charging main loop, a main control module and a controllable on-off module; the charging main loop is connectedwith an external charging power supply and an external storage battery; the main control module used for monitoring the charging state of the external storage battery and correspondingly sending outa control instruction; the controllable on-off module used for executing the control instruction of the main control module and correspondingly controlling the on-off of power supply; the controllableon-off module is arranged between the external charging power supply and the external storage battery; the input end of the controllable on-off module is connected to an input live wire of the external charging power supply; and the output end of thecontrollable on-off module is led out as an output live wire to be opened to the external storage battery; and the main control module is connected with the control end of the controllable on-off module. The invention further provides a storage battery safe charging method. Compared with the prior art, the storage battery safe charging circuit andmethod of the technical schemes provided by the invention have the advantages of high circuit safety and reliable charging, and can effectively eliminate the charging potential safety hazard caused by direct connection of the external charging power supply the an external storage battery in the prior art.

    本发明公开了一种蓄电池安全充电电路,该电路包括有用于连接外部充电电源以及外部蓄电池的充电主回路、用于监控外部蓄电池的充电状态并对应发出控制指令的主控模块以及用于执行主控模块的控制指令对应控制供电通断的可控通断模块;可控通断模块设置外部充电电源与外部蓄电池之间,其输入端接入外部充电电源的输入火线,其输出端引出作为输出火线向外部蓄电池开放;主控模块与可控通断模块的控制端连接。本发明还提供一种蓄电池安全充电方法。相比于现有技术,本发明提供的技术方案具有电路安全性高、充电可靠的有益效果,能有效解决现有技术中外部充电电源与外部蓄电池直接连接而带来的充电安全隐患。
