Compared with the previous single-gun single-use space occupied and carrying weight can be improved, so as to significantly improve the use experience, reduce production costs, and allow users to combine them according to needs for easy use.

[0019] It should be emphasized that the utility model mainly benefits from the CC loop between the ground wire and the charging connection confirmation wire in the charging and discharging gun head 21 being replaced by a gun head circuit board. The gun head circuit board is simple in design, but reasonable and efficient. The specific structure is as follows:

[0020] The gun head circuit board includes a key closing button 50 and multiple resistors and switch tubes 51, which have eight branches in total.

[0021] It can be further explained that the switch tube of the fifth branch is between the resistor R8 and the ground wire, and the resistor R4 of the third branch is set between the resistor R3 and the wire, and the resistor R10 of the second branch is set between the resistor R9 and the resistor R1. With such a design, when the portable charging and discharging gun is plugged into the charging and discharging interface of the car, the internal circuit of the portable charging and discharging gun changes the voltage of the CC port to notify the vehicle whether it is in the charging or discharging state at this time, and on this basis, with the detachable combination structure, it can meet the charging and discharging function requirements.

[0022] In order to ensure that the components in the utility model can be electrically connected to each other, each component has an output and an input terminal, and the general design is as follows: the fixed charging pile 1 leads out a power line to be electrically connected to the mains, and it also has a first plug-in port 10 and is assembled and fixed with the portable charging and discharging gun 2 to connect and transmit current; the portable charging and discharging gun 2 has one end as a second plug-in port 20 connected to the first plug-in port 10, the fourth plug-in port 40 or the third plug-in port 30, and the other end is a charging and discharging port that is plugged into the charging and discharging interface of the car.
