The invention relates to a charger which comprises a first charging module, a first charging port, a second charging port, a switch matrix circuit and a control unit. The switch matrix circuit comprises a first charging module first switch used for connecting the first charging module and the first charging port, and a first charging module second switch used for connecting the first charging module and the second charging port. The control unit is used for controlling the on-off of the first switch of the first charging module and the on-off of the second switch of the first charging module, and when the charging of the first charging port by the first charging module is required to be switched to the charging of the second charging port, the control unit is used for controlling the first switch of the first charging module to be switched off, and controlling power-off of the first charging module, and when the current value detected by the current detection circuit is zero or the voltage difference value detected by the voltage detection circuit is zero, the first charging module is controlled to be powered on, and the second switch of the first charging module is controlled to be switched on. According to the charger and the method thereof, accurate and safe charging switching of the charging module among a plurality of charging ports can be realized.

    本发明涉及一种充电器,包括第一充电模块、第一充电端口和第二充电端口、开关矩阵电路以及控制单元,所述开关矩阵电路包括用于将第一充电模块和第一充电端口进行连接的第一充电模块第一开关、用于将第一充电模块和第二充电端口进行连接的第一充电模块第二开关,所述控制单元用于控制所述第一充电模块第一开关的开闭和所述第一充电模块第二开关的开闭,当需要将第一充电模块给第一充电端口充电切换到给第二充电端口充电时,所述控制单元用于控制所述第一充电模块第一开关断开,控制所述第一充电模块断电,并当所述电流检测电路检测的电流值为零或者是所述电压检测电路检测的两端电压差值为零时,控制所述第一充电模块通电,控制所述第一充电模块第二开关闭合。本发明充电器及其方法可实现充电模块在多个充电端口之间进行准确、安全充电切换。
