[0002] With the rapid growth of the electric vehicle (EV) market, the demand for convenient and efficient charging solutions is growing. Traditional EV charging methods typically rely on dedicated charging stations or wall-mounted chargers, limiting users' ability to charge at home or at other non-dedicated charging locations. Furthermore, existing household power outlets are primarily designed to meet the power needs of traditional electrical devices and do not directly support the high power output required for EV charging. Therefore, users who want to charge their EVs from home power often need to use a conversion adapter or purchase a dedicated mobile charging device. Regardless of the method used, this increases user investment costs and may also pose safety risks, such as insufficient overload protection and aging wiring. Summary of the Invention

DETAILED DESCRIPTION

[0012] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0013] Although some current portable charging solutions can provide a certain degree of flexibility, they are often large in size, inconvenient to carry, and have a single function. They can only be used as temporary emergency measures and cannot meet long-term stable charging needs. The technical solution of the present application integrates the functions of the charging gun and the household socket strip. For example, when you need to charge an electric car, you can plug the charging gun directly into the car charging port. When you need to obtain electricity from the electric car, you can power other electrical appliances through a household three-plug. This allows users to conveniently use the same device for charging and discharging operations in different scenarios. At the same time, through the design of the CC charge and discharge conversion unit, the switching unit and the control unit, intelligent control of the charging and discharging process is also achieved. The combined use of the isolated power supply and the relay further ensures the stability and reliability of the circuit under high power conditions and avoids the risk of overload.

[0014] This embodiment provides a circuit that integrates a charging cable and a household power strip. The circuit includes a power strip module, a charging cable connector, and a conversion control module. The charging cable connector is electrically connected to the power strip module via the conversion control module. Specifically, the power strip module includes a socket unit and a household three-pin plug. The socket unit is electrically connected to the household three-pin plug, and both the socket unit and the household three-pin plug are electrically connected to the conversion control module.

[0015] In this embodiment, the socket unit is provided with multiple power sockets, and the multiple power sockets are connected in series. At the same time, one of the power sockets is electrically connected to a household three-plug. The power socket electrically connected to the household three-plug is provided with a determination discharge resistor, and the determination discharge resistor is electrically connected to the conversion control module.

[0016] Furthermore, the conversion control module includes a CC charge and discharge conversion unit, a switching unit and a control unit, wherein the gun head connector is electrically connected to the control unit through the CC charge and discharge conversion unit, the control unit is electrically connected to the discharge resistor and the switching unit, and the switching unit is electrically connected to a household three-plug.

[0017] Furthermore, the CC charge-discharge conversion unit includes an RC / resistor, an R4 / resistor, an RC resistor and an R4 resistor. The RC / resistor and the R4 / resistor are electrically connected to each other, the RC resistor and the R4 resistor are electrically connected to each other, and the R4 resistor is electrically connected to the control unit. At the same time, the series circuit composed of the RC / resistor and the R4 / resistor and the series circuit composed of the RC resistor and the R4 resistor are connected in parallel to each other, and the parallel circuit formed is electrically connected to the CC port of the gun head connector through the switch S3.

[0018] Furthermore, the switching unit includes a relay. Specifically, the L-OUT port of the gun head connector in this embodiment is electrically connected to the L1 port of the household three-plug through a relay, and the N-OUT port of the gun head connector is electrically connected to the N1 port of the household three-plug through a relay. At the same time, the L-OUT port, N-OUT port of the gun head connector and the L1 port and N1 port of the household three-plug are electrically connected to the isolated power supply 1 and the isolated power supply 2. Wherein the isolated power supply 1 and the isolated power supply 2 are respectively arranged at both ends of the relay, and the isolated power supply 1 and the isolated power supply 2 are electrically connected to the control unit. That is to say, the control unit is electrically connected to the L-OUT port and N-OUT port of the gun head connector, the L1 port and N1 port of the household three-plug, and the relay through the isolated power supply 1 and the isolated power supply 2. At the same time, the control unit is electrically connected to the CP port of the gun head connector, the parallel circuit in the CC charge-discharge conversion unit and the judgment discharge resistor, which is electrically connected to the PE port of the gun head connector and the PE port of the household three-plug.

[0019] In the specific implementation process, there are three socket units, namely power socket 1, power socket 2 and power socket 3, wherein power socket 3 is provided with a discharge judgment resistor, and power socket 3 is electrically connected to the household three-plug. Furthermore, the resistance value of the R4 resistor is set to 1.8kΩ, the resistance value of the RC resistor is set to 1.5kΩ, the resistance value of the R4 / resistor is set to 1.5kΩ, and the resistance value of the RC / resistor is set to 2kΩ. It is worth noting that in this embodiment, the resistance value of the discharge judgment resistor is set to 2K, and its resistance value can be specifically set according to actual conditions, and there is no specific restriction on its resistance value. At the same time, the relay switching current capacity is greater than 20A, and the power plug is 16A.

[0020] Furthermore, in the default state of the circuit in this embodiment, the gun tip connector is in a discharging state. Specifically, the control unit (e.g., BF7106AM64LBTX) determines the resistance value of the discharge resistor and sends a switching instruction to the relay. Specifically, when the control unit in this embodiment determines that the discharge resistor value is 2K, it sends a pull-in instruction to the relay, at which point the gun tip connector begins discharging, thereby powering the connected electric vehicle.

[0021] Similarly, when the control unit in this embodiment determines that the resistance value of the discharge resistor is not 2K, it sends an opening and closing instruction to the relay. At this time, the gun head connector can start charging, that is, the electric car connected to the gun head connector is used as a power source to supply power to the outside, and the multiple power sockets and household three-plugs connected to it all supply power to the outside.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is limited by the accompanying embodiments and their equivalents.
