Description

Technical Field

[0001] This application relates to the technical field of new energy vehicles, and particularly to a charging adapter device, a vehicle charging method, and an electronic device. Background Art

[0002] With the popularization of new energy vehicles, the requirements for vehicles are also getting higher and higher. For example, it is required that the vehicle can achieve fast charging. In related technologies, a vehicle has two charging sockets, and each of these two charging sockets can plug in a charging gun, so that the two charging guns can charge the vehicle simultaneously, thereby improving the charging speed.

[0003] However, having two charging sockets on the vehicle requires more space to arrange these two charging sockets and the lines of these two charging sockets, resulting in a relatively large occupied space of the charging sockets in the vehicle. Summary of the Invention

[0004] This application provides a charging adapter device, a vehicle charging method, and an electronic device to solve the problems provided by related technologies. The technical solutions are as follows:

[0005] In a first aspect, a charging adapter device is provided. The charging adapter device includes: a first interface, a first charging port, and a second charging port. Among them, the first interface is electrically connected to the first charging port and the second charging port respectively. The first interface is used to electrically connect to the charging socket of the vehicle. The first charging port is used to electrically connect to the first charging gun of the first charging pile. The second charging port is used to electrically connect to the second charging gun of the second charging pile. In this application, through the charging adapter device, one charging socket of the vehicle can be expanded into two or more charging ports. In this way, the vehicle only needs to arrange one charging socket, without arranging two charging sockets, reducing the occupied space of the charging socket on the vehicle.

[0006] If the vehicle needs to be charged quickly, the vehicle can use the charging adapter device to expand two or more charging ports. Each of these charging ports can insert a charging gun, and multiple charging guns can charge the vehicle simultaneously, thereby improving the charging speed of the vehicle.

[0007] In addition, in this application, the vehicle only needs to arrange one charging socket. Compared with the vehicle in related technologies that arranges two charging sockets, the number of lines, connectors, and charging sockets of the charging socket can be reduced, and the cost of the vehicle can be reduced.

[0008] Of course, the vehicle is not limited to having one charging socket, and it can also have two or more charging sockets to achieve the effect of dual charging guns with one charging socket. Since the charging adapter device provided in this application can expand more charging ports on the basis of the existing charging sockets of the vehicle, it can not only reduce the occupied space of the charging sockets on the vehicle, but also improve the charging speed of the vehicle.

[0009] In a possible implementation, there are multiple electrically conductive contacts that correspond one-to-one on the first interface, the charging socket, the first charging port, and the first charging gun. The electrically conductive contacts corresponding to each other on the first interface and the first charging port are electrically connected by a wire. When the electrically conductive contacts corresponding to each other on the first interface and the charging socket are in contact, the first interface is electrically connected to the charging socket. When the electrically conductive contacts corresponding to each other on the first charging port and the first charging gun are in contact, the first charging port is electrically connected to the first charging gun. It can be seen that the circuit of the charging adapter device is simple, the cost is reduced, and it is easy to implement.

[0010] In a possible implementation, when the first charging gun is electrically connected to the first charging port, the first electrically conductive contact of the first interface is electrically connected to one end of the first resistor of the charging socket, and the other end of the first resistor is electrically connected to the ground point of the vehicle. The first electrically conductive contact of the first charging port is electrically connected to one end of the second resistor of the first charging gun, the first controller of the first charging pile, and one end of the third resistor of the first charging pile; the other end of the second resistor is used for electrically connecting to the ground point of the first charging pile; the other end of the third resistor is grounded.

[0011] In a possible implementation, there are multiple electrically conductive contacts that correspond one-to-one on the first interface, the second charging port, and the second charging gun. The charging adapter device further includes: a fourth resistor, one end of the fourth resistor is electrically connected to the second electrically conductive contact of the first interface, and the other end of the fourth resistor is electrically connected to the first electrically conductive contact of the second charging port. The electrically conductive contacts corresponding to each other between the other electrically conductive contacts on the second charging port except the first electrically conductive contact and the first interface are electrically connected by a wire. When the electrically conductive contacts corresponding to each other on the second charging port and the second charging gun are in contact, the second charging port is electrically connected to the second charging gun. It can be seen that the circuit of the charging adapter device is simple, the cost is reduced, and it is easy to implement.

[0012] In a possible implementation, when the second charging gun is electrically connected to the second charging port, one end of the fourth resistor is electrically connected to the ground point of the vehicle, and the other end of the fourth resistor is electrically connected to one end of the fifth resistor of the second charging gun, one end of the sixth resistor of the second charging pile, and the second controller of the second charging pile; the other end of the fifth resistor is used for electrically connecting to the ground point of the second charging pile; the other end of the sixth resistor is grounded.

[0013] In a possible implementation, the charging adapter device further includes: a first connection surface and a second connection surface opposite to the first connection surface. A first interface is provided on the first connection surface. A first charging port and a second charging port are provided on the second connection surface. In the present application, the first interface, the first charging port, and the second charging port are respectively arranged on two opposite surfaces. In this way, combined with the placement position of the charging pile in the actual application scenario, it is more convenient for the charging adapter device to fit with the vehicle.

[0014] In a possible implementation, the device further includes: a locking module. The locking module is used to lock with the card slot on the charging seat of the vehicle. In this way, the setting of the locking module can fix the charging adapter device on the vehicle, making the connection between the charging adapter device and the vehicle more firm.

[0015] In a possible implementation, the charging adapter device further includes: a third connection surface adjacent to the first connection surface and the second connection surface respectively. The locking module is provided on the third connection surface. In this way, combined with the actual application scenario, it is more convenient for the charging adapter device to fit with the vehicle.

[0016] In a second aspect, a charging method for a vehicle is provided. The vehicle includes a vehicle body, and the vehicle body includes a charging seat for connecting to the above-mentioned charging adapter device; the method includes: when a first charging gun is electrically connected to the first charging port and a second charging gun is electrically connected to the second charging port, sending a first request to a first charging pile through the first charging port of the charging adapter device, and receiving a first current output by the first charging pile based on the first request through the first charging port of the charging adapter device; sending a second request to a second charging pile through the second charging port of the charging adapter device, and receiving a second current output by the second charging pile based on the second request through the second charging port of the charging adapter device; performing a charging operation on the vehicle according to the first current and the second current. In the present application, by using the charging adapter device, one charging seat of the vehicle can be expanded to have two or more charging ports, so as to achieve the effect of double charging guns charging with one charging seat, reducing the occupied space of the charging seat on the vehicle.

[0017] If the vehicle needs to be quickly charged, the vehicle can use the charging adapter device to expand two or more charging ports. Each of these charging ports can insert a charging gun, and multiple charging guns can charge the vehicle simultaneously, thereby improving the charging speed of the vehicle.

[0018] In a possible implementation, the method further includes: when the first charging gun is electrically connected to the first charging port and the second charging gun is electrically connected to the second charging port, detecting the voltage of the detection point of the vehicle; when the voltage of the detection point of the vehicle is the first voltage, performing an operation of sending a first request to the first charging pile through the first charging port of the charging adapter, or performing an operation of sending a second request to the second charging pile through the second charging port of the charging adapter, where the first voltage is used to indicate that a single charging gun is allowed to charge the vehicle. In this application, detecting the voltage of the detection point of the vehicle to select the charging mode is more in line with the actual scenario and has higher practicability.

[0019] In a possible implementation, the method further includes: when the first charging gun is electrically connected to the first charging port and the second charging gun is electrically connected to the second charging port, detecting the voltage of the detection point of the vehicle; when the voltage of the detection point of the vehicle is the second voltage, performing an operation of sending a first request to the first charging pile through the first charging port of the charging adapter, and performing an operation of sending a second request to the second charging pile through the second charging port of the charging adapter, where the second voltage is used to indicate that two charging guns are allowed to charge the vehicle. In this application, detecting the voltage of the detection point of the vehicle to select the charging mode is more in line with the actual scenario and has higher practicability.

In this application, by displaying the options of the charging mode on the display screen of the vehicle, the user can trigger the vehicle to charge in different charging modes by selecting different options, realizing flexible selection of the charging mode, enabling the user to flexibly change the charging mode of the vehicle in combination with the actual scenario, and having higher practicability.

[0021] In a possible implementation, the charging mode option includes a master-slave charging mode, the first request is used to request the first charging pile to output according to the maximum charging current of the vehicle; the second request is used to request the second charging pile to dynamically output current according to the maximum charging current of the vehicle and the actual output current of the first charging pile.

[0042] The terms used in the implementation manners part of the present application are only for explaining the specific embodiments of the present application, rather than aiming to limit the present application

[0043] New energy vehicles (referred to as vehicles for short) can achieve fast charging. In the related technology, a vehicle has two charging sockets, and each of these two charging sockets can be plugged with a charging gun Figure 1 Schematic diagram of the structure of a vehicle for the related technology, as Figure 1 shown, the vehicle 10 has two charging sockets (or called dual charging sockets), namely the first charging socket 11 and the second charging socket 12. Among them, the first charging socket 11 and the second charging socket 12 can be respectively arranged at two rear wheel hub packages of the vehicle 10. Exemplarily, as Figure 2 shown as Figure 1Schematic diagram of the arrangement of the dual charging seats of the vehicle 10 shown. The first charging seat 11 is arranged at the left rear wheel arch of the vehicle 10, and the second charging seat 12 is arranged at the right rear wheel arch of the vehicle 10.

[0044] As Figure 2 shown, taking the vehicle 10 using DC fast charging as an example, the vehicle 10 may further include a high-voltage distribution box 13 and a power battery 14. The high-voltage distribution box 13 is electrically connected to the power battery 14. The high-voltage distribution box 13 is used to play roles such as on-off, control, or protection in power transmission, distribution, power conversion, and consumption. The high-voltage distribution box 13 is electrically connected to the first charging seat 11 through a high-voltage wire 1 to receive the DC electric energy output by the charging pile through the first charging seat 11 to charge the power battery 14 of the vehicle 10. Similarly, the high-voltage distribution box 13 is electrically connected to the second charging seat 12 through a high-voltage wire 2 to receive the DC electric energy output by the charging pile through the second charging seat 12 to charge the power battery 14 of the vehicle 10.

[0045] Figure 3 For Figure 1 the schematic diagram of the structure of the vehicle charging system of the vehicle shown. As Figure 3 shown, the system 100 may include a vehicle 10, a first charging pile 20, and a second charging pile 30. When the vehicle 10 needs to be charged with a dual charging gun, the user can insert the first charging gun 21 of the first charging pile 20 into the first charging seat 11 and insert the second charging gun 31 of the second charging pile 30 into the second charging seat 12. In this way, these two charging guns can charge the vehicle 10 simultaneously, improving the charging speed.

[0046] Figure 4 For Figure 3 the schematic circuit diagram of the charging principle of the vehicle charging system 100 shown. As Figure 4 shown, the vehicle 10 may include a first charging seat 11, a second charging seat 12, a high-voltage distribution box 13, and a power battery 14. The high-voltage distribution box 13 may further include a battery management system (BMS), which is used to manage the charging and discharging of the power battery. The first charging pile 20 may include a first charging gun 21. The second charging pile 30 may include a second charging gun 31. The first charging pile 20 charges the vehicle 10 by inserting the first charging gun 21 into the first charging seat 11. And, the second charging pile 30 charges the vehicle 10 by inserting the second charging gun 31 into the second charging seat 12.

[0047] The following is for Figure 4A detailed description of the circuit shown above: The first charging gun 21, the first charging base 11, the second charging gun 31, the second charging base 12, and the high-voltage power distribution box 13 all have the following electrical contacts: direct current positive (direct current +, DC+), direct current negative (direct current -, DC-), provider edge (PE), charging communication CAN_H (S+), charging communication CAN_L (S-), charging connection confirmation 1 (charging connection confirmation1, CC1), charging connection confirmation 2 (charging connection confirmation2, CC2), low-voltage auxiliary power positive (A+), and low-voltage auxiliary power negative (A-). As Figure 4 shown, the first charging base 11 and the second charging base 12 are connected in parallel and are both electrically connected to the high-voltage power distribution box 13. A resistor R4 is provided between CC1 and PE on the first charging base 11. Similarly, a resistor R4 is provided between CC1 and PE on the second charging base 12. A resistor R2 is provided between CC1 and PE on the first charging gun 21, and a resistor R3 is provided between CC2 and PE. Similarly, a resistor R2 is provided between CC1 and PE on the second charging gun 31, and a resistor R3 is provided between CC2 and PE.

[0048] The following is a detailed description of Figure 4 the charging principle of the circuit shown above: When the vehicle 10 needs to be charged with two charging guns, the first charging base 11 of the vehicle 10 is inserted into the first charging gun 21, and the second charging base 12 of the vehicle 10 is inserted into the second charging gun 31. After that, on the charging pile side: The first charging pile 20 detects whether the first charging gun 21 is properly connected to the first charging base 11 based on the resistor R2 of the first charging gun 21 and the resistor R4 of the first charging base 11. Similarly, the second charging pile 30 detects whether the second charging gun 31 is properly connected to the second charging base 12 based on the resistor R2 of the second charging gun 31 and the resistor R4 of the second charging base 12. On the vehicle 10 side: The vehicle 10 detects whether the first charging base 11 is properly connected to the first charging gun 21 based on the resistor R3 of the first charging gun 21. Similarly, the vehicle 10 detects whether the second charging base 12 is properly connected to the second charging gun 31 based on the resistor R3 of the second charging gun 31. When the first charging gun 21 is electrically connected to the first charging base 11 and the second charging gun 31 is electrically connected to the second charging base 12, the vehicle 10 sends requests for outputting current to the first charging pile 20 and the second charging pile 30 respectively through S+, and the first charging pile 20 and the second charging pile 30 output current according to the requests to charge the vehicle 10.

[0049] In the above solution, by inserting a charging gun into each of the two charging seats, the two charging guns can charge the vehicle simultaneously, thereby improving the charging speed. However, having two charging seats on the vehicle requires more space to arrange these two charging seats and the lines of these two charging seats, resulting in a relatively large occupied space for the charging seats in the vehicle.

[0050] To solve the above technical problems, as Figure 5 shown, the present application provides a schematic structural diagram of a vehicle charging system according to an embodiment. The difference between the system 100 and the vehicle charging system provided by the above related art is that the system 100 may include a charging adapter device 40. Through this charging adapter device 40, it is possible to achieve dual charging gun charging for the vehicle 10 even when there is only one charging seat, namely the charging seat 15. Among them, the charging adapter device 40 may include a first interface 41, a first charging port 42, and a second charging port 43. The first interface 41 is electrically connected to the first charging port 42 and the second charging port 43 respectively. Among them, the first interface 41 is used to electrically connect the charging seat 15 of the vehicle 10. The first charging port 42 is used to electrically connect the first charging gun 21 of the first charging pile 20. The second charging port 43 is used to electrically connect the second charging gun 31 of the second charging pile 30. The output power of the first charging pile 20 and the second charging pile 30 is less than the charging power of the charging seat of the vehicle 10. In this case, when the first charging port 42 is electrically connected to the first charging gun 21 and the second charging port 43 is electrically connected to the second charging gun 31, the first charging pile 20 is connected to the charging seat 15 through the first charging gun 21 and the first charging port 42 to charge the vehicle 10, and the second charging pile 30 is connected to the charging seat 15 through the second charging gun 31 and the second charging port 43 to charge the vehicle 10. It can be seen that in the embodiment of the present application, two or more charging ports can be extended from one charging seat of the vehicle through the charging adapter device. In this way, the vehicle only needs to arrange one charging seat, without arranging two charging seats, reducing the occupied space of the charging seat on the vehicle.

[0051] If the vehicle needs to be quickly charged, the vehicle can use the charging adapter device to extend two or more charging ports. Each of these charging ports can insert a charging gun, and multiple charging guns can charge the vehicle simultaneously, thereby improving the charging speed of the vehicle.

[0052] In addition, in the embodiment of the present application, the vehicle only needs to arrange one charging seat. Compared with the vehicle in the related art that arranges two charging seats, the number of lines, connectors, and charging seats of the charging seat can be reduced, reducing the cost of the vehicle.

[0053] Of course, in the embodiment of the present application, Figure 5For illustration purposes, only an example where the vehicle 10 includes a charging dock 15 is given, but the present application is not limited thereto. That is to say, the vehicle 10 is not limited to having one charging dock, and may also have two or more charging docks to achieve the effect of dual charging guns with one charging dock. Since the charging adapter device 40 provided in the embodiments of the present application can expand more charging ports on the basis of the existing charging dock of the vehicle 10, it can not only reduce the occupied space of the charging dock on the vehicle, but also improve the charging speed of the vehicle.

[0054] The charging dock 15 of the above vehicle 10 can be a DC charging dock or an AC charging dock. In the embodiments of the present application, the charging dock 15 is taken as an example of a DC charging dock for illustration.

[0055] The above first charging pile 20 and second charging pile 30 can be the same charging pile or different charging piles. Similarly, the above first charging gun 21 and second charging gun 31 can belong to the same charging pile or different charging piles. The embodiments of the present application do not make specific limitations. It can be set according to actual needs during specific implementation. In the embodiments of the present application, the first charging pile 20 and the second charging pile 30 are different charging piles, the first charging gun 21 belongs to the first charging pile 20, and the second charging gun 31 belongs to the second charging pile 30.

[0056] In a possible implementation manner, the above charging adapter device 40 can be a part of the vehicle 10. Or, the above charging adapter device 40 can also be independent of the vehicle 10, and the embodiments of the present application do not make specific limitations.

[0057] The arrangement manner, position and shape of the above first interface 41, first charging port 42 and second charging port 43 on the charging adapter device 40, and the relative distance between the first interface 41, first charging port 42 and second charging port 43 are set according to actual needs, and the embodiments of the present application do not make specific limitations. In some embodiments, in order to combine the placement position of the charging pile in the actual application scenario and make it more convenient for the charging adapter device 40 to fit with the vehicle 10, such as Figure 6 and Figure 7 shown, is a schematic structural diagram of the charging adapter device 40 provided in the embodiments of the present application. As Figure 6 and Figure 7 shown, the charging adapter device 40 may further include: Figure 6 The first connection surface 411 shown, and the second connection surface 412 opposite to the first connection surface 411 (as Figure 7 shown). Among them, the first connection surface 411 is a contact surface that contacts the charging dock 15 of the vehicle 10, and the first interface 41 is provided on the first connection surface 411. The second connection surface 412 is a connection surface for connecting with the charging gun, and the second charging port 42 and the third charging port 43 are provided on the second connection surface 412.

[0058] In some other embodiments, in order to fix the charging adapter device 40 on the vehicle 10, as Figure 6 shown, the charging adapter device 40 may further include: a locking module 44. The locking module 44 is used to lock with Figure 5 the card slot on the charging base 15 of the vehicle 10 as shown. Wherein, the specific implementation structure of the locking module 44 is not specifically limited. For example, the locking module 44 may be a hook matching the card slot, or the locking module 44 may also be a fixing block matching the card slot. For the convenience of the locking module 44 and the third connection surface 413 of the card slot on the charging base 15, the third connection surface 413 is adjacent to the first connection surface 411 and the second connection surface 412 respectively. As Figure 7 shown, the locking module 44 is arranged on the third connection surface 413.

[0059] In an example, the charging adapter device 40 may further include: Figure 7 the lock switch 45 and an elastic module (not shown in the figure) as shown. The lock switch 45 can be connected to the locking module 44 through the elastic module. When the user presses the lock switch 45, the elastic module connected to the lock switch 45 is in a compressed state. At this time, the elastic module pushes the locking module 44 under the action of the elastic force, so that the locking module 44 is engaged with the card slot on the charging base 15 of the vehicle 10 to fix the charging adapter device 40 on the vehicle 10. When the user presses the lock switch 45 again, the elastic module connected to the lock switch 45 is in a compressed state. At this time, the elastic module pushes the locking module 44 under the action of the elastic force, so that the locking module 44 is separated from the card slot on the charging base 15 of the vehicle 10 to detach the charging adapter device 40 from the vehicle 10. Of course, the above is only one implementation method, and other methods may also be adopted in the embodiments of the present application, which are not specifically limited in the embodiments of the present application.

[0060] The following will Figure 5 give a detailed description of the circuit involved in the vehicle charging system as shown.

[0061] Figure 8 For Figure 5 the circuit diagram of the charging adapter device in the vehicle charging system as shown. As Figure 8 shown, there are a plurality of electrically conductive contacts corresponding one by one on the first interface 41, the first charging port 42 and the second charging port 43. Of course, there are a plurality of electrically conductive contacts corresponding one by one on the first interface 41, the charging base 15, the first charging port 42, the first charging gun 21, the first charging pile 20, the second charging port 43, the second charging gun 31 and the second charging pile 30. Exemplarily, these electrically conductive contacts may include the above Figure 4The first charging gun 21, the first charging base 11, the second charging gun 31, and the second charging base 12 in have electrical contacts. In the embodiments of the present application, the same electrical contacts on the first interface 41, the charging base 15, the first charging port 42, the first charging gun 21, the first charging pile 20, the second charging port 43, the second charging gun 31, and the second charging pile 30 are collectively referred to as one type of electrical contact. Exemplarily, the CC1s on the first interface 41, the first charging port 42, and the second charging port 43 are collectively referred to as the first electrical contacts. Similarly, the PEs on the first interface 41, the first charging port 42, and the second charging port 43 are collectively referred to as the second electrical contacts. In Figure 8 , the corresponding electrical contacts between the first interface 41 and the first charging port 42 are electrically connected by a wire. The charging adapter device 40 may further include a fourth resistor R4. One end of the fourth resistor R4 is electrically connected to the second electrical contact PE of the first interface 41, and the other end of the fourth resistor R4 is electrically connected to the first electrical contact CC1 of the second charging port 43. The other electrical contacts on the second charging port 43 except the first electrical contact CC1 are electrically connected to the corresponding electrical contacts on the first interface 41 by wires. It can be seen that the circuit of the charging adapter device is simple, the cost is reduced, and it is easy to implement.

[0062] When the corresponding electrical contacts on the first interface 41 and the charging base 15 are in contact, the first interface 41 is inserted into the charging base 15, and the first interface 41 is electrically connected to the charging base 15. When the corresponding electrical contacts on the first charging port 42 and the first charging gun 21 are in contact, the first charging gun 21 is inserted into the first charging port 42, and the first charging port 42 is electrically connected to the first charging gun 21. In this case, a Figure 5 charging circuit of the vehicle charging system as shown is formed.

[0063] Figure 9 is Figure 5 the charging circuit diagram of the vehicle charging system as shown. In the circuit diagram, the charging base 15 may include a first resistor R1. One end of the first resistor R1 is electrically connected to the body ground of the vehicle 10, and the other end of the first resistor R1 is electrically connected to one end of a second resistor R2 of the first charging gun 21, a first controller 22 of the first charging pile 20, and one end of a third resistor R3 of the first charging pile 20. The other end of the second resistor R2 is used for electrically connecting to the grounding point of the first charging pile 20. The other end of the third resistor R3 is grounded.

[0064] Among them, the connection point of the third resistor R3 and the first controller 22 is the first detection point (such as Figure 9As shown in 1), the first detection point is used by the first charging pile 20 to detect the connection status between the first charging gun 21 and the first charging port 42. The connection status can be understood as: the first charging gun 21 is electrically connected to the first charging port 42, or the first charging gun 21 is not connected to the first charging port 42. The detection method can be: when the voltage at the first detection point is the first voltage U1, the first charging pile 20 determines that the first charging gun 21 is electrically connected to the first charging port 42; when the voltage at the first detection point is not the first voltage U1, the first charging pile 20 determines that the first charging gun 21 is not connected to the first charging port 42.

[0065] Among them, the first voltage U1 is determined according to the first resistor R1, the second resistor R2, and the third resistor R3. The expression of the first voltage U1 can be: U1 = U0 / (R3 + R2*R1 / (R2 + R1))*(R2*R1 / (R2 + R1)), where U0 is a preset value, and the voltage value range of U0 can be 11.4V - 28V. The resistance value ranges of R1, R2, and R3 can be 970Ω - 1030Ω. In practical applications, assume that R1 = 1000Ω, R2 = 1000Ω, and R3 = 1000Ω. Then, the voltage value range of U1 can be 3.2V - 4.8V. Exemplarily, U1 = 4V. In Figure 9 when the voltage of the detection 1 shown in is 4V, the first charging pile 20 determines that the first charging gun 21 is electrically connected to the first charging port 42; in Figure 9 when the voltage of the detection 1 shown in is not equal to 4V, the first charging pile 20 determines that the first charging gun 21 is not connected to the first charging port 42.

[0066] Figure 9 In ① represents the current detection circuit, ② represents the discharge circuit, and ③ represents the voltage detection circuit, which will not be introduced in detail here.

[0067] When the first interface 41 is in contact with the corresponding electrical contact on the charging seat 15, the first interface 41 is inserted into the charging seat 15, and the first interface 41 is electrically connected to the charging seat 15. When the second charging port 43 is in contact with the corresponding electrical contact on the second charging gun 31, the second charging gun 31 is inserted into the second charging port 43, and the second charging port 43 is electrically connected to the second charging gun 31. In this case, in Figure 9 the shown circuit diagram, on the second charging port 43, the PE in the first interface 41 is electrically connected to the CC2 of the second charging port 43 through the fourth resistor R4. One end of the fourth resistor R4 is used to be electrically connected to the vehicle body ground of the vehicle 10, and the other end of the fourth resistor R4 is used to be electrically connected to one end of the fifth resistor R5 of the second charging gun 31, one end of the sixth resistor R6 of the second charging pile 30, and the second controller 32 of the second charging pile 30. The other end of the fifth resistor R5 is used to be electrically connected to the grounding point of the second charging pile 30. The other end of the sixth resistor R6 is grounded.

[0068] Among them, the connection point of the sixth resistor R6 and the second controller 32 is the second detection point (such as Figure 9 shown as detection point 2), and the second detection point is used for the second charging pile 30 to detect the connection situation between the second charging gun 31 and the second charging port 43. The connection situation can be understood as: the second charging gun 31 is electrically connected to the second charging port 43, or the second charging gun 31 is not connected to the second charging port 43. The detection method can be: when the voltage at the second detection point is the second voltage U2, the second charging pile 30 determines that the second charging gun 31 is electrically connected to the second charging port 43; when the voltage at the second detection point is not the second voltage U2, the second charging pile 30 determines that the second charging gun 31 is not connected to the second charging port 43.

[0069] Similarly, the same as the voltage detection method of the above-mentioned first detection point, the second voltage U2 is determined according to the fourth resistor R4, the fifth resistor R5, and the sixth resistor R6. The expression of the second voltage U2 can be: U2 = U0 / (R6 + R5 * R4 / (R5 + R4)) * (R5 * R4 / (R5 + R4)), where U0 is a preset value, and the voltage value range of U0 can be 11.4V - 28V. The resistance value ranges of the fourth resistor R4, the fifth resistor R5, and the sixth resistor R6 can be 970Ω - 1030Ω. In practical applications, assume that R4 = 1000Ω, R5 = 1000Ω, and R6 = 1000Ω. Then, the voltage value range of U2 can be 3.2V - 4.8V. Exemplarily, U2 = 4V. When Figure 9 the voltage of detection point 2 shown is 4V, the second charging pile 30 determines that the second charging gun 31 is electrically connected to the second charging port 43; when Figure 9 the voltage of detection point 2 shown is not equal to 4V, the second charging pile 30 determines that the second charging gun 31 is not connected to the second charging port 43.

[0070] In a possible implementation manner, on the vehicle side, the vehicle can also determine whether the two charging guns are connected to the two charging ports. The determination methods include but are not limited to: the vehicle body includes a third controller and a seventh resistor R7. One end of the seventh resistor R7 is electrically connected to the vehicle body ground, and the other end of the seventh resistor R7 is electrically connected to the third controller, one end of an eighth resistor R8 of the first charging gun 21, and one end of a ninth resistor R9 of the second charging gun 31. The other end of the eighth resistor R8 is electrically connected to the other end of the second resistor R2 and the equipment ground of the first charging pile 20. The other end of the ninth resistor R9 is electrically connected to the other end of the fifth resistor R5 and the equipment ground of the second charging pile 30.

[0071] Among them, the connection point of the seventh resistor R7 and the third controller is the third detection point (such as Figure 9As shown in Fig. 3), the third detection point is used for the vehicle 10 to detect the connection status of the first charging gun 21 and the first charging port 42, and the connection status of the second charging gun 31 and the second charging port 43. It can be understood that: the first charging gun 21 is electrically connected to the first charging port 42, and the second charging gun 31 is electrically connected to the second charging port 43; or, the first charging gun 21 is electrically connected to the first charging port 42, and the second charging gun 31 is not connected to the second charging port 43; or, the first charging gun 21 is not connected to the first charging port 42, and the second charging gun 31 is electrically connected to the second charging port 43; or, the first charging gun 21 is not connected to the first charging port 42, and the second charging gun 31 is not connected to the second charging port 43. The detection method can be:

[0072] 1) When the voltage at the third detection point is the third voltage U3, the vehicle 10 determines that the first charging gun 21 is electrically connected to the first charging port 42, and the second charging gun 31 is not connected to the second charging port 43. Among them, the third voltage U3 is determined according to the seventh resistor R7 and the eighth resistor R8. The expression of the third voltage U3 can be: U3 = U0 / (R8 + R7) * R8, where U0 is a preset value, and the voltage value range of U0 can be 11.4V - 28V. The resistance value ranges of the seventh resistor R7 and the eighth resistor R8 can be 970Ω - 1030Ω. In practical applications, assume that R7 = 1000Ω and R8 = 1000Ω. Then, the voltage value range of U3 can be 5.4mV - 14.8mV. Exemplarily, U3 = 12mV. In the case where Figure 9 the voltage at the third detection point shown in Fig. 3 is 12mV, the vehicle 10 determines that the first charging gun 21 is electrically connected to the first charging port 42, and the second charging gun 31 is not connected to the second charging port 43.

[0073] 2) When the voltage at the third detection point is the fourth voltage U4, the vehicle 10 determines that the first charging gun 21 is not connected to the first charging port 42, and the second charging gun 31 is electrically connected to the second charging port 43. Among them, the third voltage U3 is determined according to the seventh resistor R7 and the ninth resistor R9. The expression of the fourth voltage U4 can be: U4 = U0 / (R9 + R7) * R9, where U0 is a preset value, and the voltage value range of U0 can be 11.4V - 28V. The resistance value ranges of the seventh resistor R7 and the ninth resistor R9 can be 970Ω - 1030Ω. In practical applications, assume that R7 = 1000Ω and R9 = 1000Ω. Then, the voltage value range of U4 can be 5.4mV - 14.8mV. In practical applications, U4 = 12mV. In the case where Figure 9 the voltage at the third detection point shown in Fig. 3 is 13mV, the vehicle 10 determines that the first charging gun 21 is not connected to the first charging port 42, and the second charging gun 31 is electrically connected to the second charging port 43.

[0074] 3) When the voltage at the third detection point is the fifth voltage U5, the vehicle 10 determines that the first charging gun 21 is electrically connected to the first charging port 42, and the second charging gun 31 is electrically connected to the second charging port 43. Among them, the fifth voltage U5 is determined according to the seventh resistor R7, the eighth resistor R8, and the ninth resistor R9. The expression of the fifth voltage U5 can be: U5 = U0 / (R7+(R8+R9) / 2)*(R8+R9) / 2, where U0 is a preset value, and the voltage value range of U0 can be 11.4V - 28V. The resistance value ranges of the seventh resistor R7, the eighth resistor R8, and the ninth resistor R9 can be 970Ω - 1030Ω. In practical applications, R7 = 1000Ω, R8 = 1000Ω, R9 = 1000Ω. Then, the voltage value range of U5 can be 5.3mV - 14.8mV. Exemplarily, U5 = 14mV. In the case where Figure 9 as shown in the inspection 3, the voltage is 14mV, the vehicle 10 determines that the first charging gun 21 is electrically connected to the first charging port 42, and the second charging gun 31 is electrically connected to the second charging port 43.

[0075] 4) When the voltage at the third detection point is not the third voltage U3, the fourth voltage U4, and the fifth voltage U5, the vehicle 10 determines that the first charging gun 21 is not connected to the first charging port 42, and the second charging gun 31 is not connected to the second charging port 43. Continuing with the above example, in the case where Figure 9 as shown in the inspection 3, the voltage does not satisfy 5.3mV - 14.8mV, the vehicle 10 determines that the first charging gun 21 is not connected to the first charging port 42, and the second charging gun 31 is not connected to the second charging port 43.

[0076] After detecting that the first charging gun and / or the second charging gun is electrically connected to the vehicle, the above charging pile can charge the vehicle. The following details the charging principle of the vehicle for different connection scenarios.

[0077] Case 1, when the first charging gun 21 is electrically connected to the first charging port 42 and the second charging gun 31 is not connected to the second charging port 43, the vehicle 10 can charge in a single-gun mode. At this time, as Figure 9 shown, the third controller of the vehicle 10 sends a first request to the first controller 22 of the first charging pile 20 through the charging base 15, the first charging port 42, and the first charging gun 21. The first request is used to request the first charging pile 20 to output a first current, and the first current can be selected according to the charging requirements of the vehicle 10. The first charging pile 20 outputs the first current according to the first request. Correspondingly, the first charging pile 20 transmits the first current to the power battery of the vehicle 10 through the first charging gun 21, the first charging port 42, and the charging base 15 to realize single-gun charging of the vehicle 10.

[0078] In Case 2, similar to Case 1, when the first charging gun 21 is not connected to the first charging port 42 and the second charging gun 31 is electrically connected to the second charging port 43, the vehicle 10 can charge in a single-gun mode. At this time, as Figure 9 shown, the third controller of the vehicle 10 sends a second request to the second controller 32 of the second charging pile 30 through the charging base 15, the second charging port 43, and the second charging gun 31. The second request is used to request the second charging pile 30 to output a second current, and the second current can be selected according to the charging demand of the vehicle 10. The second charging pile 30 outputs the second current according to the second request. Correspondingly, the second charging pile 30 transmits the second current to the power battery of the vehicle 10 through the second charging gun 31, the second charging port 43, and the charging base 15 to achieve single-gun charging of the vehicle 10.

[0079] In Case 3, when the first charging gun 21 is electrically connected to the first charging port 42 and the second charging gun 31 is electrically connected to the second charging port 43, the vehicle 10 can charge in a dual-gun charging mode. Among them, the dual-gun charging mode can also include a master-slave charging mode and an equal-sharing charging mode. The master-slave charging mode can be understood as one charging pile serving as the main charging force and the other charging pile serving as the assistant of the main charging force. The equal-sharing charging mode can be understood as two charging piles outputting the same current to charge the vehicle.

[0080] The charging principles of the vehicle in different charging modes are introduced below, including but not limited to the following two charging methods.

[0081] Charging Method 1: The vehicle charges in the master-slave charging mode.

[0082] Continuing with the above example, assume that the first charging pile 20 serves as the main charging force and the second charging pile 30 serves as the assistant of the first charging pile 20. The charging principle of the vehicle can be: As Figure 9As shown, the third controller of the vehicle 10 sends a third request to the first controller 22 of the first charging pile 20 through the charging base 15, the first charging port 42, and the first charging gun 21. The third request is used to request the first charging pile 20 to output according to the maximum charging current of the vehicle 10. The first charging pile 20 outputs the maximum charging current of the vehicle 10 according to the first request. Similarly, the third controller of the vehicle 10 sends a fourth request to the second controller 32 of the second charging pile 30 through the charging base 15, the second charging port 43, and the second charging gun 31. The fourth request is used to request the second charging pile 30 to dynamically output a third current according to the maximum charging current of the vehicle 10 and the actual output current of the first charging pile 20. The third current is the difference between the maximum charging current of the vehicle 10 and the actual output current of the first charging pile 20. Correspondingly, the first charging pile 20 transmits the actual output current of the first charging pile 20 to the power battery of the vehicle 10 through the first charging gun 21, the first charging port 42, and the charging base 15. And the second charging pile 30 transmits the third current to the power battery of the vehicle 10 through the second charging gun 31, the second charging port 43, and the charging base 15 to realize dual-gun charging of the vehicle 10.

[0083] Charging method two, the vehicle charges in an equal-sharing charging mode.

[0084] Continuing with the above example, the charging principle of the vehicle can be: As Figure 9 shown, the third controller of the vehicle 10 sends a fifth request to the first controller 22 of the first charging pile 20 through the charging base 15, the first charging port 42, and the first charging gun 21. The fifth request is used to request the first charging pile to output half of the maximum charging current of the vehicle 10. The first charging pile 20 outputs half of the maximum charging current of the vehicle 10 according to the fifth request. Similarly, the third controller of the vehicle 10 sends a sixth request to the second controller 32 of the second charging pile 30 through the charging base 15, the second charging port 43, and the second charging gun 31. The sixth request is used to request the second charging pile to output half of the maximum charging current of the vehicle. The second charging pile 30 outputs half of the maximum charging current of the vehicle 10 according to the sixth request. Correspondingly, the first charging pile 20 transmits half of the maximum charging current of the vehicle 10 to the power battery of the vehicle 10 through the first charging gun 21, the first charging port 42, and the charging base 15. And the second charging pile 30 transmits half of the maximum charging current of the vehicle 10 to the power battery of the vehicle 10 through the second charging gun 31, the second charging port 43, and the charging base 15 to realize dual-gun charging of the vehicle 10.

[0085] In some embodiments, the charging mode of the vehicle can be selected in the following ways: Method one, the vehicle 10 can independently select the charging mode; Method two, the vehicle 10 can also respond to the user's operation to select the charging mode. The determination methods of these two charging modes are introduced in detail below:

[0086] The first method for determining the charging mode is that vehicle 10 can autonomously select the charging mode.

[0087] During the vehicle development stage, programmers store the relevant programs of the charging mode selection rules in the vehicle's memory, and these programs are loaded and executed by the vehicle's controller so that the vehicle can implement the charging mode selection method.

[0088] During the vehicle usage stage, the vehicle can select the charging mode for charging according to the pre-set charging mode selection rules. Continuing with the above example, a detailed introduction is as follows.

[0089] Example 1, when the voltage at the third detection point (i.e., the detection point 3 shown in Figure 9 is the above-mentioned third voltage U3, it means that the first charging gun 21 is electrically connected to the first charging port 42, and the second charging gun 31 is not connected to the second charging port 43. At this time, the third controller of vehicle 10 can determine to adopt the single-gun charging mode, that is, the third controller of vehicle 10 can determine to charge vehicle 10 with the first charging pile 20. At this time, the third controller of vehicle 10 sends the above-mentioned first request to the first charging pile.

[0090] Example 2, when the voltage at the third detection point (i.e., the detection point 3 shown in Figure 9 is the above-mentioned fourth voltage U4, it means that the first charging gun 21 is not connected to the first charging port 42, and the second charging gun 31 is electrically connected to the second charging port 43. At this time, the third controller of vehicle 10 can determine to adopt the single-gun charging mode, that is, the third controller of vehicle 10 can determine to charge vehicle 10 with the second charging pile 30. At this time, the third controller of vehicle 10 sends the above-mentioned second request to the second charging pile.

[0091] Example 3, when the voltage at the third detection point (i.e., the detection point 3 shown in Figure 9 is the above-mentioned fifth voltage U5, it means that the first charging gun 21 is electrically connected to the first charging port 42, and the second charging gun 31 is electrically connected to the second charging port 43. At this time, the third controller of vehicle 10 can determine to adopt the single-gun charging mode. The third controller of vehicle 10 can send the above-mentioned third request to the first charging pile and the above-mentioned fourth request to the second charging pile. Or, the third controller of vehicle 10 can send the above-mentioned fifth request to the first charging pile and the above-mentioned sixth request to the second charging pile.

[0092] Then, the third controller of vehicle 10 needs to select a charging pile to send the request. The selection methods can include but are not limited to the following several.

[0093] The first selection method is that the third controller of vehicle 10 can randomly specify a charging pile.

[0094] In the second selection method, the third controller of the vehicle 10 can also select a charging pile according to a preset order. For example, the preset order can include the sorting of the charging ports. Exemplarily, the third controller of the vehicle 10 can sort according to the serial numbers of the charging ports and select a charging pile. For example, assuming that the serial number of the first charging port is 1 and the serial number of the second charging port is 2, the third controller of the vehicle 10 selects the first charging pile electrically connected to the first charging port with the serial number 1 to charge the vehicle 10.

[0095] In the third selection method, the third controller of the vehicle 10 can also select according to the information of the charging pile. For example, the vehicle can obtain the output power of the first charging pile and the output power of the second charging pile. When the vehicle determines that the output power of the first charging pile is greater than the output power of the second charging pile and the output power of the first charging pile is less than the charging power of the vehicle, the third controller of the vehicle can select the first charging pile to charge the vehicle.

[0096] Determination method of charging mode II: The vehicle 10 can also select a charging mode in response to a user operation.

[0097] The vehicle 10 provided in the embodiment of the present application may further include a display screen 16. Figure 10 It is a schematic diagram of an interface of a display screen 16 of a vehicle 10 provided in the embodiment of the present application. As Figure 10 shown, when the first charging gun is electrically connected to the first charging port and the second charging gun is electrically connected to the second charging port, the display screen 16 of the vehicle 10 displays a first interface 161, and the first interface 161 includes at least one charging mode option. Among them, the charging mode options can include a single-gun charging mode and a double-gun charging mode. The double-gun charging module can include a master-slave charging mode and an equal-sharing charging mode. Of course, the double-gun charging mode can also include other modes, such as a specified-ratio charging mode, which is not specifically limited in the embodiment of the present application.

[0098] Exemplarily, as Figure 10The first interface 161 shown may include a first option and a second option. The first option represents the master-slave charging mode. The second option represents the equal-sharing charging mode. When the user selects the first option, in response to the user's selection operation, the third controller of the vehicle 10 may designate the first charging pile as the main charging force and the second charging pile as the charging assistant. At this time, the third controller of the vehicle 10 sends the above-mentioned third request to the first charging pile, and the third request is used to request the first charging pile to output current according to the maximum charging current of the vehicle. And, the third controller of the vehicle 10 sends the above-mentioned fourth request to the second charging pile, and the fourth request is to request the second charging pile to output current according to the maximum charging current of the vehicle and the actual output current of the first charging pile. When the user selects the second option, in response to the user's selection operation, the third controller of the vehicle 10 sends the above-mentioned fifth request to the first charging pile, and the fifth request is used to request the first charging pile to output current at half of the maximum charging current of the vehicle. And, the third controller of the vehicle 10 sends the above-mentioned sixth request to the second charging pile, and the sixth request is used to request the second charging pile to output current at half of the maximum charging current of the vehicle.

[0099] In a possible implementation manner, the first interface may further include a third option, and the third option represents charging using the first charging pile. When the user selects the third option, in response to the user's selection operation, the third controller of the vehicle sends the above-mentioned first request to the first charging pile, and the first request is used to request the first charging pile to output current. Similarly, the first interface may further include a fourth option, and the fourth option may represent charging using the second charging pile. When the user selects the fourth option, in response to the user's selection operation, the third controller of the vehicle sends the above-mentioned second request to the second charging pile, and the second request is used to request the second charging pile to output current.

[0100] In the embodiments of the present application, by displaying options of charging modes on the display screen of the vehicle, the user can trigger the vehicle to charge the vehicle using different charging modes by selecting different options, realizing flexible selection of charging modes, enabling the user to flexibly change the charging mode of the vehicle in combination with the actual scenario, and having higher practicability.

[0101] The embodiments of the present application provide a charging method for a vehicle, and this method can be applied to the above Figures 5 - 10 shown implementation environment. Among them, the vehicle may include a vehicle body. The vehicle body may include a charging seat, and the charging adapter device includes a first interface, a first charging port, and a second charging port, and the first interface is respectively conducted with the first charging port and the second charging port; the first interface is used for electrically connecting to the charging seat, the first charging port is used for electrically connecting to the first charging gun of the first charging pile, and the second charging port is used for electrically connecting to the second charging gun of the second charging pile. Figure 11 is a schematic flowchart of the charging method for the vehicle provided by the embodiments of the present application, asFigure 11 As shown, the method may include S111 - S122 (where some steps are optional steps).

[0102] S111. The first charging pile detects the connection status between the first charging gun and the first charging port.

[0103] The connection status between the first charging gun and the first charging port can be understood as: the first charging gun is electrically connected to the first charging port, or, the first charging gun is not connected to the first charging port.

[0104] In an implementable manner, S111 may include S1111 - S1112.

[0105] S1111. When it is detected that the voltage value at the first detection point of the first charging pile is the first threshold, it is determined that the first charging gun is electrically connected to the first charging port. Wherein, the first detection point of the first charging pile is the Figure 9 detector 1 shown. The first threshold may be a preset value. Exemplarily, the first threshold can be determined according to Figure 9 the first resistor R1 of the charging base 15, the second resistor R2 of the first charging gun 21, and the third resistor R3 of the first charging pile 20 shown, that is, the above-mentioned first voltage U1. The implementation of S1111 can refer to the above relevant description and will not be elaborated here.

[0106] S1112. When it is detected that the voltage value at the first detection point of the first charging pile is not the first threshold, it is determined that the first charging gun is not connected to the first charging port. Wherein, the implementation of S1112 can refer to the above relevant description and will not be elaborated here.

[0107] S112. The second charging pile detects the connection status between the second charging gun and the second charging port.

[0108] The connection status between the second charging gun and the second charging port can be understood as: the second charging gun is electrically connected to the second charging port, or, the second charging gun is not connected to the second charging port.

[0109] In a possible implementation manner, S112 may include S1121 and S1122.

[0110] S1121. When it is detected that the voltage value at the second detection point of the second charging pile is the second threshold, it is determined that the second charging gun is electrically connected to the second charging port. Wherein, the second detection point of the second charging pile is the Figure 9 detector 2 shown. The second threshold may be a preset value. Exemplarily, the second threshold can be determined according to Figure 9Determined by the first resistor R1 of the charging dock 15, the fifth resistor R5 of the second charging gun 31, and the sixth resistor R6 of the second charging pile 30 shown in [figure], the above-mentioned second voltage U2 is obtained. Exemplarily, the fifth resistor R5 can be the same as the second resistor R2, and the sixth resistor R6 can be the same as the third resistor R3. For the implementation of S1121, reference can be made to the above relevant description and will not be elaborated here.

[0111] S1122. When it is detected that the voltage value at the second detection point of the second charging pile is not the second threshold value, it is determined that the second charging gun is not connected to the second charging port. For the implementation of S1122, reference can be made to the above relevant description and will not be elaborated here.

[0112] Of course, the vehicle side will also detect the connection status of the first charging gun to the first charging port and the second charging gun to the second charging port. For the specific implementation method, reference can be made to the above relevant description and will not be elaborated here.

[0113] After it is detected that the first charging gun is electrically connected to the first charging port and the second charging gun is electrically connected to the second charging port, the vehicle will send requests to the first charging pile and the second charging pile respectively. However, the trigger timing for the vehicle to send requests to the charging piles can include:

[0114] Trigger timing one (such as Figure 11 the AND-1 shown in [figure]), the vehicle sends a request to the charging pile according to the voltage at the third detection point of the vehicle. Reference can be made to S113 - S116:

[0115] S113. When the first charging gun is electrically connected to the first charging port and the second charging gun is electrically connected to the second charging port, the vehicle detects the voltage at the detection point of the vehicle.

[0116] The detection point of the vehicle is Figure 8 the detection point 3 shown in [figure]. The voltage at the third detection point of the vehicle is determined by Figure 9 the seventh resistor R7, the eighth resistor R8, and the ninth resistor R9 shown in [figure].

[0117] S114. When the voltage at the detection point of the vehicle is the first target voltage, the vehicle sends a first request to the first charging pile. The first request is used to request the first charging pile to output the first current.

[0118] The above-mentioned first target voltage is the above-mentioned third voltage U3. The first target voltage is determined according to Figure 9 the seventh resistor R7 and the eighth resistor R8 shown in [figure].

[0119] Among them, the first request is the first request in the above embodiment. The first current can be any output current of the first charging pile, and the current is less than or equal to the maximum charging current of the vehicle. When the voltage at the detection point of the vehicle is the third voltage U3, it means that the first charging gun is electrically connected to the first charging port. At this time, the vehicle sends the first request to the first charging pile through the first charging port of the charging adapter device.

[0120] S115. When the voltage at the detection point of the vehicle is the second target voltage, the vehicle sends a second request to the second charging pile. The second request is used to request the second charging pile to output a second current.

The second current can be any output current of the second charging pile, and the current is less than or equal to the maximum charging current of the vehicle. Moreover, the sum of the second current and the first current is less than or equal to the maximum charging current of the vehicle.

[0122] When the voltage at the detection point of the vehicle is the fourth voltage U4, it means that the second charging gun is electrically connected to the second charging port.

[0125] The above third target voltage is the above fifth voltage U5, and the third target voltage is determined according to Figure 9 the seventh resistor R7, the eighth resistor R8 and the ninth resistor R9 shown.

[0126] When the voltage at the detection point of the vehicle is the fifth voltage U5, it means that the first charging gun is electrically connected to the first charging port, and the second charging gun is electrically connected to the second charging port. At this time, the vehicle can send the first request to the first charging pile or send the second request to the second charging pile.

[0127] To reasonably distribute the first current output by the first charging pile and the second current output by the second charging pile. Then, the vehicle can select the master-slave charging mode or the equal-sharing charging mode.

The first interface includes at least one charging mode option, and the charging mode option can include the master-slave charging mode, the equal-sharing charging mode, or the single-gun charging mode.

[0130] Exemplarily, the first interface can refer to Figure 10 the interface shown in

[0131] S118. In response to receiving the selection operation for the master-slave charging mode, the vehicle sends a first request to the first charging pile. The first request is used to request the first charging pile to output according to the maximum charging current of the vehicle; and, the vehicle sends a second request to the second charging pile. The second request is to request the second charging pile to dynamically output current according to the maximum charging current of the vehicle and the actual output current of the first charging pile.

[0132] S119. In response to receiving the selection operation for the equal-sharing charging mode, the vehicle sends a first request to the first charging pile. The first request is used to request the first charging pile to output at half of the maximum charging current of the vehicle; and, the vehicle sends a second request to the second charging pile. The second request is used to request the second charging pile to output at half of the maximum charging current of the vehicle.

The user can trigger the vehicle to charge in different charging modes by selecting different options, realizing the flexible selection of the charging mode, enabling the user to flexibly change the charging mode of the vehicle in combination with the actual scenario, and having higher practicability.

[0134] After the first charging pile receives the first request, the first charging pile executes S120, which can be:

[0135] S120. The first charging pile outputs the first current to the vehicle through the first charging gun and the first charging port of the charging adapter according to the first request. Correspondingly, the vehicle receives the first current.

[0136] After the second charging pile receives the second request, the first charging pile executes S121, which may be as follows:

[0137] S121. According to the second request, the second charging pile outputs a second current to the vehicle through the second charging gun and the second charging port of the charging adapter. Correspondingly, the vehicle receives the second current.

[0138] S122. The vehicle performs a charging operation on the vehicle according to the first current and the second current.

[0139] In the embodiment of the present application, two or more charging ports can be extended from one charging seat of the vehicle through the charging adapter. If the vehicle needs to be quickly charged, the vehicle can use the charging adapter to extend two charging ports, and each of these two charging ports can insert a charging gun. The vehicle can be electrically connected to two charging guns respectively through the two charging ports of the charging adapter, so that the current output by the charging pile can be transmitted to the charging seat of the vehicle through the two charging guns and the charging adapter, thereby realizing simultaneous charging of the vehicle by the two charging guns, and further improving the charging speed of the vehicle.
