CHARGING DEVICE AND OPERATING METHOD THEREOF

A charging device and an operating method thereof are provided. The charging device is installed to a power system through a first power line, a second power line and a ground line. The charging device includes a first processor, a second processor and a microcontroller. The first processor is coupled to the first power line and the second power line and is used to generate a first voltage determination signal. The second processor is coupled to the second power line and the ground line, and is used to generate a second voltage determination signal. The microcontroller is coupled to the first processor and the second processor, and is used to determine a power standard of the power system according to the first voltage determination signal and the second voltage determination signal.
