[0009] Wherein, the first connector is used to access the first port, and the second connector is used to access the second port (9), so that while the communication wire harness between the first charging socket and the battery control manager forms a first communication loop, a second communication loop is formed among the second charging socket, the transfer socket, the first transfer plug, and the battery control manager through the communication wire harness.

[0013] Wherein, the third connector is used to access the third port, and the fourth connector is used to access the first port, so that the communication wire harness between the first charging socket and the battery control manager and the communication wire harness between the second charging socket and the battery control manager form a third communication loop.

[0014] Optionally, there is also an on-off signal line between the battery control manager and the adapter socket;

[0024] The embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0025] The new energy vehicle charging communication system according to the embodiments of the present utility model will be described below with reference to the drawings.

[0026] In one embodiment of the present utility model, referring to Figure 1 , a new energy vehicle charging communication system is provided, including: a first charging socket 1, a second charging socket 2, a battery control manager 4, a transfer socket 5, and a first transfer plug 6;

[0027] The first charging socket 1 is connected to the battery control manager 4 through a communication wire harness 3;

[0028] The second charging socket 2 is connected to the first port 8 of the transfer socket 5 through a communication wire harness 3;

[0029] The battery control manager 4 is connected to the second port 9 of the transfer socket 5 through a communication wire harness 3;

[0030] The first transfer plug 6 includes a first connector 10 and a second connector 11, and a communication wire harness is connected between the first connector 10 and the second connector 11;

[0031] Wherein, the first connector 10 is used to access the first port 8, and the second connector 11 is used to access the second port 9, so that while the communication wire harness between the first charging socket 1 and the battery control manager 4 forms a first communication loop, a second communication loop is formed among the second charging socket 2, the transfer socket 5, the first transfer plug 6, and the battery control manager 4 through the communication wire harness.

[0032] The above battery management controller 4 may refer to a BMS (Battery Management System), which is used to monitor the battery state, control the power-on and power-off logic, and perform fault protection.

[0033] In one embodiment, the communication wire harness is a Controller Area Network (CAN) communication wire harness. Figure 1Take the CAN communication harness as an example. The CAN bus uses twisted pair for differential voltage transmission. S1+ and S1- are a set of CAN communication harnesses. S1+ is connected to CAN1_H to form the CAN high signal line, and S1- is connected to CAN1_L to form the CAN low signal line.

[0034] Similarly, S2+ and S2- are a set of communication harnesses.

[0035] Figure 2 For the case of using the first adapter plug 6, the dual-pile independent charging mode is realized. As Figure 2 shown, the second charging socket 2 is connected downward to the adapter socket 5 through the communication harness 3, and can be connected to the first port 8 through the internal harness in the adapter socket 5.

[0036] Ports matching the connectors of the communication harness 3 can be provided on the adapter socket 5, so that the communication harness 3 is connected to the adapter socket 5.

[0037] According to Figure 2 the alignment method, insert the first adapter plug 6 into the adapter socket 5. The first port 8 is connected to the first connector 10, the second connector 11 is connected to the second port 9, S2+ is connected to CAN2_H, and S2- is connected to CAN2_L to form the second communication loop.

[0038] At the same time, for the first charging socket 1, S1+ is connected to CAN2_1, and S1- is connected to CAN1_L to form the first communication loop.

[0039] In this way, by forming two independent communication loops, the charging sockets 1 and 2 can communicate with two independent charging piles respectively. Thus, after successful communication, two charging piles can be used for power supply, improving the power supply efficiency.

[0040] The specific charging method can be to insert the charging gun on the charging pile into each charging socket for power supply.

[0041] In one embodiment, the above system further includes: a second adapter plug 7;

[0042] The second adapter plug 7 includes a third connector 12 and a fourth connector 13, and a communication harness is connected between the third connector 12 and the fourth connector 13;

[0043] The communication harness 3 between the first charging socket 1 and the battery control manager 4 is connected in parallel to the third port 14 of the adapter socket 5;

[0044] Among them, the third connector 12 is used to access the third port 14, and the fourth connector 13 is used to access the first port 8, so that the communication wire harness between the first charging socket 1 and the battery control manager 4 and the communication wire harness between the second charging socket 2 and the battery control manager 4 form a third communication loop.

[0045] The third communication loop is as Figure 3 shown, realizing the single-pile dual-gun charging mode, corresponding to the scenario of using two charging guns belonging to one charging pile.

[0046] As Figure 3 shown, when the third connector 12 accesses the third port 14 and the fourth connector 13 accesses the first port 8, the second adapter plug 7 is inserted into the adapter socket 5.

[0047] In this way, S2+ is connected to CAN1_H, S2- is connected to CAN1_L, and at the same time, S1+ is connected to CAN1_H, S1- is connected to CAN1_L, forming a third communication loop in which the first charging socket 1 and the second charging socket 2 are in parallel.

[0048] Since the two charging guns belong to the same charging pile, only one communication loop needs to be used to communicate with the charging pile to trigger charging.

[0049] In one embodiment, there is also an on-off signal line between the battery control manager 4 and the adapter socket 5;

[0050] The on-off signal line is connected by the connection lines in the first adapter plug 6 when the first connector 10 is used to access the first port 8 and the second connector 11 is used to access the second port 9.

[0051] As Figure 1 shown, the on-off signal line is composed of A and B communication wire harnesses.

[0052] In the first adapter plug 6, there are connection lines corresponding to the A and B communication wire harnesses, located on the right side of the second connector 11. When docking with the adapter socket 5, the A and B communication wire harnesses and the connection lines form a loop, as Figure 2 shown. Thus, the on-off of the adapter socket can be controlled.

[0053] Taking the first port 8 and the first connector 10 as an example to illustrate the connection between each port and the corresponding connector, the first port 8 may include DB_9 terminals, among which there are pins corresponding to CAN high and pins corresponding to CSN low, so that the CAN high and CSN low lines connected by the first connector 10 complete the connection of the communication wire harness as the first connector is inserted into the pins.

[0054] The first connector 10 is the pin of the corresponding standard for the first port 8.

[0055] The second port, the third port, and the fourth port can all be connected to the corresponding interfaces in this way.

[0056] The above system further includes a battery high-voltage distribution box, and the battery high-voltage distribution box is respectively connected to the first charging socket and the second charging socket through power lines.

[0057] In the case of the existence of the first communication loop, after the charging pile obtains a charging instruction through the first communication loop, it accesses the first charging socket through the charging gun, is connected to the battery high-voltage distribution box via the power line of the first charging socket, and supplies power to the new energy vehicle battery. The process of supplying power to the second charging socket is similar. Thus, the embodiments of the present utility model can be used in various charging scenarios for new energy commercial vehicles. The above system can be integrated into the vehicle, and different charging modes can be realized by switching to use the first adapter plug or the second adapter plug. Only by replacing the first and second adapter plugs, the function switching of single-pile and double-pile charging can be flexibly realized without changing the in-vehicle wiring, achieving compatibility with two charging modes, without increasing additional costs, and expanding the charging scenarios for vehicle users.

[0058] The communication processes of the second communication loop and the third communication loop are similar to that of the first communication loop.

[0059] Since the first communication loop and the second communication loop are independent charging circuits, when using the first adapter plug, two communication loops, namely the first communication loop and the second communication loop, are formed, so that communication interaction can be independently carried out with two charging piles. Both charging piles can independently achieve charging based on communication without the situation of communication errors caused by sharing a charging loop between the two charging piles.
