[0040] The plug-in component is the charge and discharge plug 2. Thus, power is supplied through the connection between the charge and discharge plug 2 and the connecting component. After the live wire end safety switch at the bottom of the charge and discharge plug 2 is inserted into the socket strip 1, when the switch is pressed, the live wire of the charge and discharge plug 2 becomes energized; the connecting component is a three-core cable 3. One end of the three-core cable 3 is fixed to the charge and discharge plug 2, and the other end of the three-core cable 3 is fixed to the charge and discharge gun head 4. Thus, the power of the charge and discharge plug 2 is transmitted to the charge and discharge gun head 4 through the three-core cable 3;

[0041] It further includes a socket strip 1. The charge and discharge plug 2 is plugged into the socket strip 1. Thus, power can be provided to the charge and discharge gun head 4 through the connection between the charge and discharge plug 2 and the socket strip 1. One end of the socket strip 1 is provided with a socket strip power-on / off indicator light. Furthermore, the user can be reminded whether it is powered on through the light of the indicator light.

[0042] At the bottom of one end of the charge and discharge gun head 4, there is a first charge and discharge emergency stop switch 5. Thus, after the first charge and discharge emergency stop switch 5 is pressed, the vehicle can be quickly stopped from charging and discharging. After it is pressed again, it resumes to the charging mode. From one end to the other end of the top of the charge and discharge gun head 4, there are successively fixed a first charging current adjustment switch 9, a first charging current indicator light 8, and a micro switch 7. Furthermore, by pressing the first charging current adjustment switch 9, the charging current can be adjusted to 5kw or 7.5kw. When the current is 5kw, two gears of 8A or 16A can be adjusted.

The safety lock 6 is connected to the micro switch 7. Furthermore, after the safety lock 6 is inserted into the charge and discharge gun head 4 and into the vehicle slow charging port, it can be unlocked by pressing the first charging current adjustment switch 9.

[0043] Inside the charge and discharge plug 2, there is a plug indicator light 10. Thus, the charge and discharge plug 2 being energized can be represented by the lighting of the plug indicator light 10. When the plug indicator light 10 is off, the charge and discharge plug 2 is not energized. Inside the charge and discharge plug 2 and at one end of the plug indicator light 10, there is a safety switch 11. Thus, after the charge and discharge plug 2 is inserted into the inside of the socket strip 1, it is energized when the safety switch 11 is pressed. When the socket strip is pulled out, the safety switch automatically rebounds and cuts off the power. Furthermore, the first wire of the three-core cable 3 is connected to the live wire point L on the charge and discharge plug 2, the third wire of the three-core cable 3 is connected to the neutral wire N on the charge and discharge plug 2, and the connection point of the first wire and the third wire forms the plug indicator light 10.

The other end at the top of the charging control module 12 is connected to a reset switch 14. The reset switch 14 is installed between the ground wire and CC at the top of the charging control module 12, so as to switch between 5kw or 7.5kw through the reset switch 14. When the reset switch 14 is long-pressed, the blue indicator light will be constantly on; after the blue indicator light goes out, release the button; it indicates that the power has been switched;

[0045] The normally closed contact at the bottom of the micro switch 7 is connected to the charging resistor 15. The charging resistor 15 is a 2000 resistor. The normally open contact at the bottom of the micro switch 7 is connected to the discharging resistor 16.

At this time, the power of the charging and discharging plug 2 enters the inside of the charging and discharging gun head 4 through the three-core cable 3. Then, the working state of the first charging current indicator light 8 is used to judge whether it is in the charging mode or the discharging mode through whether the indicator light emits light, and at the same time, the micro switch 7 is used to adjust to the charging mode or the discharging mode.
