For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0041] The embodiments of the present application will be described below with reference to Figures 1 to 5 .

[0042] According to the embodiments of the present application, a conversion wire harness 100 is provided, as shown in Figure 1 , both ends of the conversion wire harness 100 are charging bases, wherein the first charging base 10 at one end of the conversion wire harness 100 is connected with the charging gun of the external power supply, and the second charging base 20 at the other end of the conversion wire harness 100 is connected with the charging gun of the power supply vehicle, so as to charge the power supply vehicle by the external power supply. Moreover, the charging gun of the power supply vehicle is also used to charge the external load, and the charging gun of the external power supply and the charging gun of the power supply vehicle both have electronic locks.

[0043] In the embodiment, the charging seat of the power supply vehicle is not necessary. When the external power supply charges the power supply vehicle, the charging gun of the external power supply can be connected with the charging gun of the power supply vehicle through the adapter wire harness 100, so as to charge the power supply vehicle. When the power supply vehicle discharges to the external load, the charging gun of the power supply vehicle can be directly connected with the external load. Through the adapter wire harness 100 of the application, the charging and discharging of the power supply vehicle can be realized only by using the charging gun of the power supply vehicle. Since the charging gun of the external power supply and the charging gun of the power supply vehicle are both provided with electronic locks, the safety of the user can be ensured when the user plugs and unplugs the charging gun.

[0044] It should be noted that the external power supply can be a charging pile, a vehicle-mounted power supply of an external vehicle, etc., and the external load can be an electric vehicle such as an electric heavy truck or an electric engineering machinery, but the application is not limited thereto.

[0045] Since the electronic lock with the charging protection function is located in the charging gun, the charging seat is not provided with the electronic lock, and the related art generally realizes the charging and discharging of the power supply vehicle through the cooperation of the charging seat and the charging gun. That is to say, the existing power supply vehicle discharges and charges through two independent discharging circuits and charging circuits, or the charging and discharging of the same circuit are controlled to be mutually exclusive through a switching component. However, the hardware circuit design of the above two schemes is relatively complex and has a high cost.

[0046] In the application, when the power supply vehicle is charged, the charging gun of the power supply vehicle is connected with the charging gun of the external power supply through the adapter wire harness 100, so as to charge the power supply vehicle itself. When the power supply vehicle is discharged, the charging gun of the power supply vehicle is directly connected with the external load. In the embodiment of the application, the adapter wire harness 100 enables the power supply vehicle to realize the charging of the external load and the charging of the power supply vehicle itself only by using the charging gun of the power supply vehicle, and the hardware cost is low.

[0047] In the embodiment of the application, when the power supply vehicle is charged, the charging seats at both ends of the adapter wire harness 100 are connected with the charging gun of the power supply vehicle and the charging gun of the external power supply, respectively. Since the charging gun itself is provided with an electronic lock mechanism, the accidental situation that the user unplugs the charging gun during charging is avoided, so as to prevent electric shock and electric arc caused by unplugging the gun during charging, reduce the safety hidden danger, and ensure the personal safety of the user.

[0048] In the embodiment of the application, the two ends of the adapter wire harness are charging seat structures, and the power supply vehicle which does not have a charging seat (or the charging seat is damaged) and only has a charging gun can also use the adapter wire harness 100 for charging, and the application scenarios are more extensive. The electronic lock mechanism of the charging gun can ensure that the charging gun of the power supply vehicle and the adapter wire harness 100 and the charging gun of the external power supply and the adapter wire harness 100 are in a connected state during charging of the power supply vehicle, so that the user does not need to guard the power supply vehicle during charging, the labor cost is reduced, and the user experience is improved.

[0049] It should be noted that the specific structure of the adapter wire harness 100 is not limited in the embodiments of the present application, because the main innovation of the present application is the connection between the adapter wire harness, the charging gun of the power supply vehicle and the charging gun of the external power supply, so as to realize the effect that the power supply vehicle is charged only by using the charging gun and the adapter wire harness and is discharged by using the charging gun. As for the specific structure of the adapter wire harness 100, it can be set according to the actual use environment, for example, the cross section of the adapter wire harness 100 can be circular, polygonal, etc., and the length of the adapter wire harness 100 can be set according to the distance between the power supply vehicle and the external power supply. These adjustments all belong to the protection scope of the embodiments of the present application.

[0050] In some optional embodiments, as shown in Figure 2 , the pin specifications of the first charging seat 10 and the second charging seat 20 are consistent.

[0051] Specifically, the pin definitions of the first charging seat 10 and the second charging seat 20 should follow the preset standard, and the pin connection mode of the first charging seat 10 and the second charging seat 20 can be designed according to the actual application scene of the power supply vehicle. The pin specifications of the first charging seat 10 and the second charging seat 20 are consistent, so that the electrical signals such as current and communication signals can be transmitted in the adapter wire harness 100, and transmitted to the power supply vehicle and the external power supply through the interface between the charging gun and the charging seat, so that the power supply vehicle and the external power supply can control the charging process of the power supply vehicle based on the electrical signals in the charging process.

[0052] In some optional embodiments, the wire core of the adapter wire harness 100 includes a high-voltage wire harness, and the high-voltage wire harness is connected between the high-voltage pins of the first charging seat 10 and the second charging seat 20.

[0053] Specifically, referring again to Figure 2 , the high-voltage pins of the first charging seat 10 include a positive DC+ and a negative DC-, and the high-voltage pins of the second charging seat 20 also include a positive DC+ and a negative DC-. As shown in Figure 3 , the high-voltage wire harness includes a positive high-voltage wire harness and a negative high-voltage wire harness. One end of the positive high-voltage wire harness is connected with the positive DC+ of the high-voltage pins of the first charging seat 10, and the other end of the positive high-voltage wire harness is connected with the positive DC+ of the high-voltage pins of the second charging seat 20. One end of the negative high-voltage wire harness is connected with the negative DC- of the high-voltage pins of the first charging seat 10, and the other end of the negative high-voltage wire harness is connected with the negative DC- of the high-voltage pins of the second charging seat 20.

[0054] In the embodiments of the present application, the high-voltage wire harness is connected between the high-voltage pins of the first charging seat 10 and the second charging seat 20 of the adapter wire harness 100, so that high-voltage electricity can be transmitted in the adapter wire harness 100, and the charging of the power supply vehicle is realized.

[0055] It should be noted that the specific structure of the high-voltage wire harness is not limited in the embodiments of the present application, because the main innovation of the embodiments of the present application is the structural relationship among the high-voltage wire harness, the first charging base 10 and the second charging base 20, so as to realize the effect of transmission of high-voltage electricity in the adapter wire harness 100. As for the specific structure of the high-voltage wire harness, it can be set according to actual needs, for example, the high-voltage wire harness can use a bellows and the bellows is nested with a sleeve, the wire harness color of the negative high-voltage wire harness can be black, and the wire harness color of the positive high-voltage wire harness can be red. These adjustments are all within the protection scope of the embodiments of the present application.

[0056] In some optional embodiments, the wire core of the adapter wire harness 100 includes a communication wire harness, and the communication pins of the first charging base 10 and the communication pins of the second charging base 20 are connected through the communication wire harness. The communication wire harness includes a CAN signal communication wire harness.

[0057] Specifically, the communication wire harness can include a high-level signal line and a low-level signal line. Referring again to Figure 2 , the communication pins of the first charging base 10 include a high-level communication pin S+ and a low-level communication pin S-, and the communication pins of the second charging base 20 also include a high-level communication pin S+ and a low-level communication pin S-. One end of the high-level signal line is connected to the high-level communication pin S+ of the first charging base 10, and the other end of the high-level signal line is connected to the high-level communication pin S+ of the second charging base 20. One end of the low-level signal line is connected to the low-level communication pin S- of the first charging base 10, and the other end of the low-level signal line is connected to the low-level communication pin S- of the second charging base 20.

[0058] Specifically, since the charging bases at both ends of the adapter wire harness 100 are the same charging loop, the charging loop state parameters (current, voltage, etc.) of the charging bases at both ends of the adapter wire harness 100 are the same, and the same pins corresponding to the communication signals are directly connected, so that the power car and the external power supply can read all the charging loop state parameters. The power car and the external power supply can communicate using CAN signals, and the communication wire harness can be a CAN signal communication wire harness, but the present application is not limited thereto.

[0059] In the embodiments of the present application, the communication pins of the first charging base 10 and the communication pins of the second charging base 20 of the adapter wire harness 100 are connected with the communication wire harness, so that the communication signals can be transmitted in the adapter wire harness 100, and the power car and the external power supply can control the charging process of the power car based on the communication signals.

[0060] It should be noted that the specific structure of the communication wire harness is not limited in the embodiments of the present application, because the main innovation of the embodiments of the present application is the structural relationship among the communication wire harness, the first charging seat 10 and the second charging seat 20, so as to realize the effect of transmitting the communication signal in the adapter wire harness 100. As for the specific structure of the communication wire harness, such as the wire diameter and color, it can be set according to actual needs.

[0061] In some optional embodiments, the wire core of the adapter wire harness includes a first configuration channel wire and a second configuration channel wire, referring again to Figure 2 , the first interface CC1 of the configuration channel pin of the first charging seat 10 and the first interface CC1 of the configuration channel pin of the second charging seat 20 are connected through the first configuration channel wire, and the second interface CC2 of the configuration channel pin of the first charging seat 10 and the second interface CC2 of the configuration channel pin of the second charging seat 20 are connected through the second configuration channel wire.

[0062] Specifically, the first configuration channel wire and the second configuration channel wire are used to detect the connection state of the first charging seat and the second charging seat. The configuration channel (CC) can detect whether the charging seat is connected with the charging gun through the voltage of the two CC wires.

[0063] By setting the first configuration channel wire and the second configuration channel wire between the first charging seat 10 and the second charging seat 20, the external power supply can determine the connection state between the charging gun of the external power supply and the first charging seat 10 of the adapter wire harness 100, and the power supply vehicle can determine the connection state between the charging gun of the power supply vehicle and the second charging seat 20 of the adapter wire harness 100.

[0064] In some optional embodiments, the wire core of the adapter wire harness further includes a ground wire harness, referring again to Figure 2 , the ground pin G of the first charging seat and the ground pin G of the second charging seat are connected through the ground wire harness, so as to charge the adapter wire harness.

[0065] In some optional embodiments, the first interface CC1 of the configuration channel pin of the first charging seat 10 is connected with the ground pin G of the first charging seat 10 through a first resistor, and the second interface CC2 of the configuration channel pin of the first charging seat 10 is suspended, that is, not connected with a cable; the first interface CC1 of the configuration channel pin of the second charging seat 20 is connected with the ground pin G of the second charging seat 20 through a second resistor, and the second interface CC2 of the configuration channel pin of the second charging seat 20 is suspended.

[0066] Alternatively, the second interface CC2 of the configuration channel pin of the first charging base 10 is connected with the first resistance and the ground pin G of the first charging base 10, and the first interface CC1 of the configuration channel pin of the first charging base 10 is left floating. The second interface CC2 of the configuration channel pin of the second charging base 20 is connected with the second resistance and the ground pin G of the second charging base 20, and the first interface CC1 of the configuration channel pin of the second charging base 20 is left floating.

[0067] Specifically, the first resistance and the second resistance can be 1KΩ, and the application is not limited thereto. When the power supply vehicle is charging, the charging bases at both ends of the adapter wire harness 100 are connected with the charging gun, so that only the detection state of the charging gun needs to be detected, that is, the CC1 signal is detected, the CC1 pin is connected to the ground pin G of the charging base through a 1KΩ resistance, and the CC2 pin is directly left floating. Alternatively, the CC2 signal can also be detected, the CC2 pin is connected to the ground pin G of the charging base through a 1KΩ resistance, and the CC1 pin is directly left floating.

[0068] The application grounds the first interface CC1 of the configuration channel pin of the first charging base 10 and the second charging base 20, or grounds the second interface CC2 of the configuration channel pin of the first charging base 10 and the second charging base 20, so as to detect the connection state of the charging base according to the first configuration channel line or the second configuration channel line.

[0069] In some optional embodiments, the wire core of the adapter wire harness 100 includes a temperature detection wire harness, and the temperature detection pin of the first charging base 10 and the temperature detection pin of the second charging base 20 are connected through the temperature detection wire harness. The temperature detection pin is used to detect the temperature of the charging base.

[0070] Specifically, the temperature of the charging base at both ends of the adapter wire harness can be detected by the temperature sensor of the charging gun at both ends, so that the temperature detection pin of the charging base can be left floating.

[0071] The application detects the temperature of the charging base through the temperature detection pin, so as to facilitate the power supply vehicle and the external power supply to control the charging process of the power supply vehicle based on the temperature of the charging base, and prevent the charging base from overheating.

[0072] In some optional embodiments, the wire core of the adapter wire harness 100 includes an auxiliary power supply wire harness, and the auxiliary power supply pin of the first charging base and the auxiliary power supply pin of the second charging base are connected through the auxiliary power supply wire harness.

[0073] Specifically, referring again to Figure 2 The auxiliary power supply wire harness is used to provide control power for the charged device, and since the power supply vehicle is self-provided with control power, the auxiliary power supply pins A+ and A- of the first charging base 10 and the auxiliary power supply pins A+ and A- of the second charging base 120 can be left floating.

[0074] According to the embodiments of the present application, a power supply vehicle is provided, as shown in Figure 4 The power supply vehicle has a conversion wire harness 100, as shown in Figure 1

[0075] Exemplarily, as shown in Figure 5 When the power supply vehicle is charging, the charging gun of the power supply vehicle is connected with the charging gun of the external charging pile through the conversion socket of the conversion wire harness, and when the power supply vehicle is discharging, the charging gun of the power supply vehicle can be directly connected with the external electric vehicle. That is, when the power supply vehicle outputs current to the outside, it is realized only through the self-owned charging gun; when the external charging pile charges the power supply vehicle, the charging gun of the charging pile is connected with one end of the conversion wire harness, and the other end of the conversion wire harness is connected with the charging gun of the power supply vehicle, so as to realize inputting current (power compensation) to the power supply vehicle.

[0076] In the above embodiments, the charging seats at both ends of the conversion wire harness are connected with the charging guns, and the charging guns all have electronic lock structures. No matter the charging gun of the power supply vehicle or the charging gun of the external charging pile of the power supply vehicle, the electronic lock signal can be controlled through the corresponding controller, so as to avoid that the charging gun is mistakenly pulled out during charging and discharging.

[0077] Although the embodiments of the present application are described in combination with the drawings, various modifications and variations can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and variations all fall within the scope defined by the appended claims.​
