A charge device includes a charge circuit and a monitoring circuit. The charge circuit includes a current limiting element, a rectifier element, and a DC voltage supply unit. The rectifier element is connected with the current limiting element in series. The DC voltage supply unit is used for providing a DC voltage to the battery to charge the battery via the current limiting element and the rectifier element connected with the current limiting element in series. The monitoring circuit includes a temperature sensing unit and a first control unit. The temperature sensing unit is used for sensing a surface temperature of the battery. The first control unit is used for controlling the DC voltage supply unit to stop charging the battery when the surface temperature is higher than a predetermined temperature.
