[0018] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0019] The new energy vehicle charging and discharging device of the present invention primarily utilizes some components used in the charging and discharging process for common use, thereby reducing manufacturing costs and reducing storage space. Specifically, various embodiments are provided below for illustration.

[0020] In an embodiment of a new energy vehicle charging and discharging device, Figure 3-4 As shown, it includes a gun cable assembly, a charging connector 6, and a discharge power strip 5. The gun cable assembly includes a gun head 1 that plugs into the vehicle and a cable 2 connected to the rear of the gun head 1. The end of the cable 2 is connected to an adapter 7. The charging connector 6 is used to connect an external power source to the adapter 7 on the gun cable assembly. It includes a housing, a plug 4 mounted on the housing, and an adapter connector. The plug 4 is designed to plug into a mains outlet or other power outlet. The adapter connector can be plugged into the adapter 7. The combination of the charging connector 6 and the gun cable assembly enables charging of new energy vehicles from an external power source. The discharge power strip 5 includes a housing, a receptacle provided on the housing, and an adapter connector. The discharge power strip 5 connects to the adapter 7 on the gun cable assembly through the adapter connector. It also has a receptacle for plugging into the adapter plug 4 of an electrical device. The adapter 7 and the adapter connector can be either a plug 4 or a receptacle, depending on the application.

[0021] In one embodiment, a control module for controlling charging is preferably provided in the charging connector 6. The control module can realize functions such as undervoltage protection, overcurrent protection, leakage protection, overtemperature protection, relay adhesion detection, fault prompt, vehicle-end diode detection, short-circuit protection, and status display during the charging process. The control module is a commonly used module in existing charging devices and can realize the above functions. It will not be described in detail herein. Of course, in other embodiments, the control module can be integrated into the gun head 1. Such a gun head 1 with an integrated control module is also an existing gun head 1 and will not be described in detail herein.

[0022] In an embodiment of a new energy vehicle charging and discharging device, Figure 5 As shown, it includes a gun head 1, a charging cable assembly for direct connection to an external power source, and a discharge cable assembly for connecting to an electrical device. The rear end of the gun head 1 is equipped with an adapter connector 7, and the front end is adapted to plug into the vehicle. The gun head 1 is a charging and discharging gun capable of both charging and discharging. Both the charging and discharge cable assemblies include a cable 2 and an adapter connector at the end of the cable 2 that mates with the adapter connector 7. The other end of the discharge cable assembly is connected to a discharge socket 5, and the other end of the charging cable assembly is connected to a plug 4.

[0023] By using the charging cable assembly in conjunction with the gun head 1, the plug 4 is connected to an external power source, the adapter connector 7 is plugged into the adapter connector, and the vehicle can be charged through the gun head 1. By using the discharging cable assembly in conjunction with the gun head 1, the adapter connector is plugged into the adapter connector, and the gun head 1 is plugged into the vehicle, external electrical devices can be powered through the discharging socket 5.
