[0031] Among them, the second pins with the same function on at least two charging gun connectors 2 are connected one by one, wherein the second pins with the same function are used to connect the second pins with the same function in the charging gun; the common end of the connection of the second pins is connected to at least one first pin in the vehicle connector 1.

[0032] Specifically, the charging gun adapter provided by the utility model can be applicable to the charging gun on any charging pile, especially to the charging gun on the household charging pile. Figure 1 The case where the charging gun adapter includes two charging gun connectors 2 is schematically shown.

[0033] The second pin includes a first confirmation pin CP1 for connecting to a control confirmation pin CP in the charging gun, a second confirmation pin CC1 for connecting to a charging connection confirmation pin CC in the charging gun, a ground pin PE1 for connecting to a body ground pin PE in the charging gun, a power pin L1 for connecting to a live wire pin L of an AC power supply in the charging gun, and a neutral pin N1 for connecting to a neutral wire pin N of an AC power supply in the charging gun. Optionally, the second pin may also include a first spare pin NC1 and a second spare pin NC2. The first confirmation pins CP1 of different charging gun connectors 2 are connected to at least one first pin after being connected to each other, the second confirmation pin CC1 is connected to at least one first pin after being connected to each other, the ground pin PE1 is connected to at least one first pin after being connected to each other, the power pin L1 is connected to at least one first pin after being connected to each other, and the neutral pin N1 is connected to at least one first pin after being connected to each other.

The first confirmation pin CP1 of the first charging gun connector 201 is connected to the first confirmation pin CP1 of the second charging gun connector 202, and the common end A5 of the first confirmation pin CP1 is connected to the fifth first pin 5. In other words, the charging gun adapter allows the charging guns on the charging pile to be plugged together, so that the power of the charging guns on the charging pile is aggregated together, thereby shortening the charging time. For example, a 3.5KW slow charge can be increased to a 7KW slow charge, a 7KW slow charge can be increased to a 14KW slow charge, and an 11KW slow charge can be increased to a 22KW slow charge.

[0035] In some embodiments, the connection wires connected to the power pin L1 and the neutral pin N1 can be made of copper busbars with a specification of not less than 20 mm. 2 The connecting wire can also be equipped with an insulating sleeve or an insulating rubber-dipped skin.

[0036] The charging gun adapter provided by the utility model does not use power electronic devices, and all functions are completed by mechanical structures. The main circuit impedance is extremely low, and the heat loss is almost negligible, so it has high reliability and high efficiency. In addition, there is no software protocol matching requirement, and it can be adapted to various slow-charging vehicles.

[0037] The charging gun adapter of the utility model comprises a vehicle connector and at least two charging gun connectors, wherein the charging gun connector is connected to the charging gun on the charging pile. By connecting the second pins with the same function on the at least two charging gun connectors one by one, and then connecting the common end of the second pins to at least one first pin in the vehicle connector, the charging guns on the charging pile can be plugged together, and the power of the charging guns on the charging pile can be aggregated together, thereby shortening the charging time.

[0038] Based on the above embodiments, Figure 8 This is a circuit diagram of another charging gun adapter provided by the utility model, refer to Figure 8 Optionally, the second pin includes a first confirmation pin CP1 for connecting to a control confirmation pin CP in the charging gun, and the charging gun adapter also includes a switch module 3.

[0039] A first end of the switch module 3 is connected to the first confirmation pin CP1 , and a second end of the switch module 3 is connected to the common end A5 of the first confirmation pin CP1 .

The switch module 3 can be arranged between the first confirmation pin CP1 of one of the charging gun connectors and the common terminal. The switch module 3 can be arranged between the first confirmation pin CP1 of the first charging gun connector 201 and the common terminal A5, or between the first confirmation pin CP1 of the second charging gun connector 201 and the common terminal A5.

[0041] The charging gun on the charging pile establishes a charging confirmation connection with the vehicle through the charging gun adapter. The charging confirmation connection process includes at least charging connection confirmation and charging control confirmation. The charging gun determines whether the charging gun and the vehicle charging port are fully connected by detecting the resistance value between the charging connection confirmation pin CC and the body ground pin PE. The charging gun confirms the maximum power supply current of the current power supply device through the control confirmation pin CP. When the charging gun establishes a charging confirmation connection with the vehicle, charging can be performed after the connection is successful. If the connection is unsuccessful, you need to press the normally closed button switch S1 to re-match. At a charging pile with a billing system, you can scan the identification code on the charging gun to re-match.

When the charging guns on the charging pile are connected together through the charging gun connector, the resistance value of the detection resistor in the charging gun will become smaller. By connecting the resistor module 4 in series between the second confirmation pin CC1 and the common end A1 of the second confirmation pin CC1, the resistance value of the detection resistor can be increased to ensure the normal use of the charging gun. Optionally, the wire connected to the second confirmation pin CC1 and the normally closed button switch S1 can be a No. 22 wire.

[0043] Based on the above embodiments, continue to refer to Figure 8 Optionally, the resistance module 4 includes at least one resistor R1; the first end of the resistor R1 serves as the first end of the resistance module 4, and the second end of the resistor R1 serves as the second end of the resistance module 4.

The second housing portion includes a second side surface B2, which is a surface of the second housing portion 601 away from the first housing portion.

[0048] The charging gun connector 2 is arranged on the first side surface B1, and the vehicle connector 1 is arranged on the second side surface B2. At least two charging gun connectors 2 are arranged on the first side surface B1 along the width direction of the first housing portion 601. Such an arrangement can help shorten the distance between the second pin and the first pin and reduce the length of the connecting wire inside the housing.

[0049] Optionally, the width of the first housing portion 601 gradually decreases in the direction X from the first side B1 to the second side B2. This arrangement can reduce the overall volume of the charging gun connector, reduce the weight of the charging gun adapter, facilitate gripping, and can be picked up and placed with one hand.
