AI Technical Summary
Technical Problem
Existing charging stations consume a lot of power in standby mode, resulting in energy waste.
Method used
By introducing switching devices and an auxiliary power supply into the charging module, and using a control unit to control the switching devices to turn on and off, the auxiliary power supply is not supplied in standby mode, thereby reducing the power consumption of the charging module.
Benefits of technology
This significantly reduces the energy consumption of the charging module in standby mode, thus reducing energy waste.

Abstract
The application provides a charging device, which comprises a charging module and a second control unit. The charging module comprises a switching device, an auxiliary power supply, a first control unit and a rectifier circuit. The auxiliary power supply supplies power to the first control unit, and the first control unit is used for controlling the rectifier circuit. The first end of the switching device is connected to the output end of the rectifier circuit or an alternating current power supply, and the second end of the switching device is connected to the input end of the auxiliary power supply. The second control unit is used for controlling the conduction and the turn-off of the switching device. In response to the conduction of the switching device, the auxiliary power supply supplies power to the first control unit; and in response to the turn-off of the switching device, the auxiliary power supply stops supplying power to the first control unit.
