[0014] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0015] The new energy vehicle charging and discharging device of this utility model mainly adapts and shares some components used in the charging and discharging process, thereby reducing manufacturing costs and the space required for storage. Specifically, different embodiments are provided below for illustration.

[0016] In one embodiment of a new energy vehicle charging and discharging device, as shown in Figures 3-4, it includes a charging cable assembly, a charging connector 6, and a discharging power strip 5. The charging cable assembly includes a charging head 1 that plugs into the vehicle and a cable 2 connected to the tail of the charging head 1. An adapter connector 7 is connected to the end of the cable 2. The charging connector 6 connects to an external power source and the adapter connector 7 on the charging cable assembly. It includes a housing, a plug 4 mounted on the housing, and an adapter connector. The plug 4 is used to plug into a mains outlet or other power socket, and the adapter connector can be adapted to plug into the adapter connector 7. Thus, by combining the charging connector 6 and the charging cable assembly, the new energy vehicle can be charged using an external power source. The discharging power strip 5 includes a housing, a socket on the housing, and an adapter connector. The discharging power strip 5 connects to the adapter connector 7 on the charging cable assembly via the adapter connector, and it has a socket for the adapter plug 4 of the electrical device to plug into. Either the adapter connector 7 or the adapter connector can be a plug 4 and a socket, depending on the usage requirements.

[0017] In one embodiment, a control module for controlling charging is preferably provided within the charging connector 6. This control module enables functions such as undervoltage protection, overcurrent protection, leakage protection, overtemperature protection, relay sticking detection, fault indication, 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 perform the above functions; therefore, it will not be described in detail here. Of course, in other embodiments, the control module can be integrated within the charging head 1. Such a charging head 1 with an integrated control module is also a conventional charging head 1, and will not be described further here.

[0018] In one embodiment of a new energy vehicle charging and discharging device, as shown in Figure 5, it includes a charging head 1, a charging cable assembly for direct connection to an external power source, and a discharging cable assembly for connecting to electrical equipment. The tail of the charging head 1 is equipped with an adapter connector 7, and the front end is used for plugging into the vehicle. The charging head 1 is a charging and discharging gun capable of charging and discharging. Both the charging cable assembly and the discharging cable assembly include a cable 2 and an adapter connector at the end of the cable 2 that is compatible with the adapter connector 7. The other end of the discharging cable assembly is connected to a discharging power strip 5, and the other end of the charging cable assembly is connected to a plug 4.

[0019] When used with the charging cable assembly and the charging gun head 1, the plug 4 is connected to an external power source, and the adapter connector 7 is plugged into the matching connector. The vehicle can then be charged through the charging gun head 1. When used with the discharging cable assembly and the charging gun head 1, the adapter connector is plugged into the matching connector, and the charging gun head 1 is plugged into the vehicle. External electrical devices can then be powered through the discharging power strip 5.

[0020] Based on the above embodiments, in one embodiment, the discharge power strip 5 can be a socket with a single socket, allowing the adapter plug 4 of the electrical device to be plugged in; in a more preferred embodiment, the discharge power strip 5 is provided with multiple discharge sockets, at least some of which are different types of sockets, such as some three-hole sockets, some two-hole sockets, and some USB sockets, which can be adapted as needed. Both the adapter connector 7 and the adapter connector are provided with power and signal contacts. When the vehicle discharges externally, the vehicle confirms the discharge mode by detecting the CC resistance inside the external electrical product, and then the vehicle discharges.

[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
