[0027] In order to make the technical problems, technical solutions and beneficial technical effects to be solved by the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0028] As mentioned above, Figure 1 As shown, the vehicle charging socket 3' generally includes a panel 33' and a DC charging socket 31' and an AC charging socket 32' arranged on the panel. The two charging sockets have different socket arrangements. For example, the DC charging socket 31' has a nine-hole DC charging socket arrangement that meets the national standard, and the AC charging socket 32' has a seven-hole AC charging socket arrangement that meets the national standard. Here, the national standard can be, for example, GB / T 18487.1. However, there is always a distance between the two separate charging sockets, which means that the charging socket requires a certain amount of assembly space, which is not friendly to vehicles with smaller spaces, such as compact vehicles. To this end, it is necessary to propose an integrated solution for AC and DC charging sockets.

[0029] Figure 2 A conceptual diagram illustrating the technical concept of the present invention is provided. According to the technical concept of the present invention, a charging socket 3 is provided on the vehicle body, retaining only a DC charging socket 31. When DC charging is required, a DC charging gun can be directly plugged into the DC charging socket. When AC charging is required, a conversion adapter 1 is used to achieve physical compatibility between the AC charging gun 2 and the DC charging socket 31.

[0030] Therefore, according to some embodiments of the present invention, a conversion adapter 1 for charging a vehicle includes an input portion 11 and an output portion 12, wherein the input portion 11 is provided with an AC socket arrangement structure adapted to the AC charging gun 2, and the output portion 12 is provided with a DC pin arrangement structure adapted to the DC charging socket 31 of the vehicle. The AC socket arrangement structure includes a plurality of sockets, and the DC pin arrangement structure includes a plurality of pins, and the plurality of sockets and the plurality of pins are electrically connected so that the AC power from the AC charging gun 2 can be delivered to the DC charging socket 31 to charge the vehicle. Here, the input portion 11 may, for example, have a structure such as Figure 1 The output portion 12 may have a socket arrangement structure like the AC charging socket 32 ′ shown, and may have a pin arrangement structure like a conventional DC charging gun, in particular a socket / pin arrangement structure that meets the national standard GB / T 18487.1.

[0031] By using the adapter 1, the AC charging gun 2 can be adapted to the DC charging socket 31, which further allows the conventional AC charging socket (such as Figure 1 32 ') and only retain the DC charging socket, thereby realizing the integrated solution design of AC and DC dual charging modes.

[0032] Based on this, Figure 3 As shown, in some embodiments according to the present invention, the charging socket 3 may include a panel 33 and a DC charging socket 31 thereon. Since only the DC charging socket 31 is provided on the panel 33, a miniaturized charging socket can be advantageously realized.

[0033] Figure 4 FIG. 1 shows a schematic diagram of electrical connections between the adapter 1, the AC charging gun 2, and the DC charging socket 31 according to an exemplary embodiment of the present invention. Figure 4 As shown, in the adapter 1, the AC jack arrangement structure of the input part 11 includes a live wire jack L1, a neutral wire jack N, and a grounding jack PE1, and the DC pin arrangement structure of the output part 12 includes a DC positive pin DC+, a DC negative pin DC-, and a grounding pin PE2, wherein the live wire jack L1 is electrically connected to the DC positive pin DC+, the neutral wire jack N is electrically connected to the DC negative pin DC-, and the grounding jack PE1 is electrically connected to the grounding pin PE2. The electrical connection between the jack pins of the AC jack arrangement structure and the DC pin arrangement structure can be as follows: Figure 2 The input portion 11 and the output portion 12 extend into the intermediate connecting portion 13 shown. In this case, the adapter 1 may include the intermediate connecting portion 13, with the input portion 11 and the output portion 12 located on either side of the intermediate connecting portion 13 and connected by the intermediate connecting portion 13. In the illustrated embodiment, the intermediate connecting portion 13 is generally plate-shaped, and the input portion 11 and the output portion 12 are generally parallel to the intermediate connecting portion 13. In some unillustrated embodiments, the input portion 11 and the output portion 12 may not be parallel, but may be perpendicular or at an angle in three-dimensional space, for example.

[0034] In addition, in the transfer adapter 1, as Figure 4 As shown, the AC socket arrangement structure of the input part 11 also includes a connection confirmation socket CC and a control guide socket CP, and the DC pin arrangement structure of the output part 12 also includes a charging device connection confirmation pin CC1 and a vehicle connection confirmation pin CC2, wherein the connection confirmation socket CC is electrically connected to the vehicle connection confirmation pin CC2, and the control guide socket CP is electrically connected to the charging device connection confirmation pin CC1. It should be understood that Figure 4In the diagram, there is a correspondence between ports or pin sockets with the same or corresponding numbers. For example, when the AC charging gun 2 is connected to the DC charging socket 31 through the adapter 1, the live wire pin L1 of the AC charging gun 2 is inserted into the live wire socket L1 of the adapter 1, and the DC positive pin DC+ of the adapter 1 is inserted into the DC positive socket DC+ of the DC charging socket 31 of the vehicle charging socket 3, and so on.

[0035] Optionally, in some embodiments, the adapter 1 may include an electronic lock to mechanically lock the adapter 1 from the DC charging socket 31 and / or the AC charging connector 2, thereby preventing accidental disconnection during AC charging operations. The electronic lock may be controlled by the vehicle controller of the vehicle charging system 100, described below.

[0036] Some embodiments of the present invention also provide a vehicle charging system. Figure 5 FIG. 1 shows a schematic structural diagram of a vehicle charging system 100 according to an exemplary embodiment of the present invention. Figure 5 As shown, the vehicle charging system 100 includes a charging socket 3, a high voltage battery 4, an onboard charger 5 and a vehicle controller (not shown). The charging socket 3 specifically has only a DC charging socket 31, ie, no AC charging socket.

[0037] The DC charging socket 31 can be Figure 4 As shown, it has DC positive and negative jacks DC+ and DC-, as well as a ground jack PE. The high-voltage battery 4 forms a battery circuit 40 with the DC positive and negative jacks of the DC charging socket 31. The onboard charger 5 forms a charger circuit 50 with the DC positive and negative jacks of the DC charging socket 31. The vehicle controller is configured to: when DC charging is determined to be in progress, control the battery circuit 40 to conduct, thereby transmitting DC power from the DC charging socket 31 to the high-voltage battery 4; and when AC charging is determined to be in progress, control the battery circuit 40 to disconnect and control the charger circuit 50 to conduct, thereby transmitting AC power from the DC charging socket 31 to the onboard charger 5. Here, AC power is specifically supplied from the AC charging plug 2 to the DC charging socket 31 via the aforementioned adapter 1.

[0038] The vehicle charging system 100 further includes, in particular, a power distribution unit 6 arranged between the charging socket 3 and the high-voltage battery 4 and the onboard charger 5 . Figure 6 FIG. 1 shows a schematic diagram of electrical connections between a high voltage battery 4, an onboard charger 5 and a power distribution unit 6 according to an exemplary embodiment of the present invention. Figure 6 As shown, the battery circuit 40 and the charger circuit 50 both pass through the power distribution unit 6 .

[0039] The battery circuit 40 is provided with a first switch unit 8, which is used to open and close the battery circuit 40. The charger circuit 50 is always kept open. The high-voltage battery 4 is electrically connected to the on-board charger 5 via the charger battery circuit (not shown).

[0040] Preferably, if Figure 6 As shown, the DC positive jack DC+ of the DC charging socket 31 can be connected to the positive terminal of the high-voltage battery 4 and the current input port of the on-board charger 5, respectively. The DC negative jack DC- of the DC charging socket 31 can be connected to the negative terminal of the high-voltage battery 4 and the current output port of the on-board charger 5, respectively, thereby forming a battery circuit 40 and a charger circuit 50, respectively. The high-voltage battery 4 and the on-board charger 5 are connected in parallel with respect to the DC charging socket 31.

[0041] Therefore, when performing AC charging via the adapter 1, the first switch unit 8 can be opened to disconnect the battery circuit 40. The AC power input from the DC charging socket 31 is transmitted to the onboard charger 5 via the charger circuit 50. In the onboard charger 5, the AC power is converted to DC power and then transmitted to the high-voltage battery 4 for charging. When performing DC charging by directly plugging a DC charging plug into the vehicle's DC charging socket 31, the first switch unit 8 can be closed to connect the battery circuit 40. The DC power input from the DC charging socket 31 can be transmitted directly to the high-voltage battery 4 via the battery circuit 40 for charging. In this case, the onboard charger 5 is in bypass mode, skipping its corresponding charging function.

[0042] Preferably, the first switch unit 8 is arranged in the power distribution unit 6, that is, on the high-voltage side of the on-board charging system 100, thereby efficiently integrating the functions of the power distribution unit 6. The first switch unit 8 can be electrically connected to the vehicle controller in various suitable communication methods to achieve data and / or command transmission, thereby achieving control of the first switch unit 8 by the vehicle controller. Preferably, the first switch unit 8 can be a single-pole double-throw switch.

[0043] Alternatively, the DC charging operation or AC charging operation to be performed can be determined by detecting the control pilot (CP) signal of the DC charging socket 31. For example, after the charging gun is properly connected, if the detected CP signal is a level signal, it can be determined that the DC charging operation is to be performed. If the detected CP signal is a PWM signal, it can be determined that the AC charging operation is to be performed. In this way, the charging operation type can be identified solely by relying on logical control and electrical control.

[0044] In particular, the DC charging socket 31 includes a charging device connection confirmation CC1 port and a vehicle connection confirmation CC2 port. The vehicle controller can be configured to configure the CC1 port as a control guide line CP port and the CC2 port as a connection confirmation line CC port when it is determined that an AC charging operation is to be performed, thereby supporting AC charging operation.

[0045] Furthermore, if Figure 7 As shown, the vehicle charging system 100 may also specifically include a charging interface controller 7. The vehicle controller may be configured to implement the configuration of the charging device connection confirmation CC1 port and the vehicle connection confirmation CC2 port through the charging interface controller 7. Thus, the vehicle controller may send relevant instructions to the charging interface controller 7, and the charging interface controller 7 may execute the configuration of the charging device connection confirmation CC1 port and the vehicle connection confirmation CC2 port. For example, when the AC charging gun 2 is connected to the DC charging socket 31 through the adapter 1 for AC charging, the CP pin of the AC charging gun 2 will be connected to the CC1 port of the DC charging socket 31. At this time, the level signal of the CC1 port of the DC charging socket 31 can be converted into a PWM signal by the charging interface controller 7. Thus, the structure of the adapter 1 can be simplified, thereby reducing costs and improving adaptability.

[0046] Preferably, if Figure 7 As shown, the charging device connection confirmation CC1 port and the vehicle connection confirmation CC2 port can be electrically connected to the charging interface controller 7 via a second switch unit 9. The second switch unit 9 can be, in particular, a single-pole, double-throw switch to enable synchronous configuration of the charging device connection confirmation CC1 port and the vehicle connection confirmation CC2 port. Thus, when the second switch unit 9 is in a first state, the CC1 and CC2 ports of the DC charging socket 31 can be connected to a first circuit structure within the charging interface controller 7 corresponding to DC charging operation, thereby using electrical signals from the CC1 and CC2 ports to control DC charging operation. When the second switch unit 9 is in a second state, the CC1 and CC2 ports of the DC charging socket 31 can be connected to a second circuit structure within the charging interface controller 7 corresponding to AC charging operation, thereby using electrical signals from the CC1 and CC2 ports to control AC charging operation. This facilitates switching of electrical signals, circuit structures, and communication protocols, enabling multiplexing of the CC1 and CC2 ports and supporting the implementation of an integrated AC / DC design.

[0047] It should be understood that in the above-mentioned multiplexing configuration of the CC1 port and the CC2 port, in addition to the adjustment and switching of the vehicle charging system, it may also involve the adjustment and switching of the circuit structure inside the charging device (such as a charging pile), which may depend on the data and instruction transmission between the vehicle charging system and the charging device and the switching of the corresponding circuit based on the instructions.

[0048] like Figure 7 As shown, the DC charging socket 31 of the charging outlet 3 may also have an auxiliary power positive jack A+, an auxiliary power negative jack A-, a DC connection control guide positive jack S+, and a DC connection control negative jack S-. Sockets S+ and S- together form a CAN bus communication network, used to transmit various charging-related data and control signals between the vehicle and the charging device, such as information such as the vehicle battery voltage, current, and SOC (State of Charge), as well as charging power, charging status, and other instructions sent by the charging station to the vehicle. Sockets A+ and A- are the auxiliary power supply positive and negative terminals for the 12V or other suitable low-voltage DC power supply provided by the charging station to the vehicle. They are used to wake up the vehicle's vehicle controller and other related control units, providing power support for the vehicle's charging preparation and control and monitoring functions during the charging process. Specifically, when AC charging is determined to be performed, sockets A+, A-, S+, and S- are controlled to be left floating.

[0049] Some embodiments of the present invention further relate to a vehicle comprising the vehicle charging system 100. Here, the vehicle may be an electric vehicle or a plug-in hybrid vehicle.

[0050] Therefore, the physical interface compatibility between the AC charging gun and the DC charging socket is achieved through the adapter according to certain embodiments of the present invention, and the physical protocol switching of AC to DC is achieved through the vehicle charging system according to certain embodiments of the present invention, thereby realizing an AC / DC integrated design solution.

[0052] Although specific embodiments of the present invention are described in detail herein, they are provided for illustrative purposes only and should not be considered to limit the scope of the present invention. Various substitutions, changes, and modifications may be conceived without departing from the spirit and scope of the present invention.
