The buck-boost module 5 is controlled by the MCU control module 3 and is used to adjust the voltage. When the MCU control module 3 turns on the first charging mode, the buck-boost module 5 is used to receive the electrical signal output by the PFC inverter main power module 4, and then the buck-boost module 5 boosts or bucks the electrical signal output by the PFC inverter main power module 4.

When the discharge gun is inserted into the first discharge terminal 21, the discharge gun detection module 22 is used to detect the electrical signal parameters of the discharge gun. At the same time, the discharge gun detection module 22 sends a first discharge signal to the MCU control module 3, so that the MCU control module 3 turns on the first discharge mode.
