[0081] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0082] The following describes a charging control device, a vehicle charging interface assembly, a charging control steering circuit, a charging control method, a computer-readable storage medium, a vehicle controller, and a vehicle proposed in an embodiment of the present application with reference to the accompanying drawings.

[0083] With the development of electric vehicles, more and more models are exported. In order to meet the needs of the export market, vehicles need to achieve Japanese standard DC charging.

[0084] In the related technology, a conversion module EVCC is added to the national standard (complying with the Chinese national standard GB / T 20234) DC charging vehicle to achieve Japanese standard (complying with the Japanese charging standard CHAdeMO) DC charging. The conversion module EVCC converts and outputs the national standard signal after performing certain logical judgment based on the received Japanese standard signal, while other controls in the vehicle remain in the national standard state unchanged.

[0085] Based on the above solution, the Japanese standard charging vehicle model can simply add an EVCC conversion module to the national standard charging vehicle model, and other control modules such as the vehicle's BMS (Battery Management System) can remain in a unified state.

[0086] The Japanese standard DC charging implementation scheme in the related technology is as follows Figure 1 As shown in the figure, the national standard DC charging implementation scheme is as follows Figure 2 As shown. Among them, CHAdeMO refers to the Japanese charging standard, and the conversion module EVCC realizes the conversion between the signal of the Japanese charging standard and the signal of the national charging standard, and then outputs the signal that meets the national charging standard to the vehicle BMS, so that the vehicle BMS can continue to perform charging control according to the national charging standard. Among them, the national standard BMS refers to the BMS that performs charging control according to the national charging standard.

[0087] However, the above technical solution has the following disadvantages:

[0088] ① The conversion module EVCC is developed as an independent controller, which leads to a significant increase in the cost of Japanese standard charging vehicles;

[0089] ② When the Japanese charging standard is adopted, the charging control signal is processed and converted by the conversion module EVCC before being given to the main controller, i.e. the national standard BMS, which increases the probability of system failure and deteriorates stability;

[0090] ③ The Japanese standard charging vehicle model is equipped with a conversion module EVCC, but the vehicle control system still has multiple states of Japanese standard and national standard, which is not convenient for management.

[0091] In order to solve the above technical problems, the present application proposes a charging control device, wherein the first control unit is connected to the first pin, the second pin and the third pin respectively, and the first control unit determines the current charging standard to be executed based on at least one of the detection signal of the first pin, the detection signal of the second pin and the detection signal of the third pin. The charging control device can determine the charging standard according to one or more of the detection signal of the first pin, the detection signal of the second pin and the detection signal of the third pin, and perform charging according to the determined charging standard, so as to be compatible with multiple charging standards. Compared with the application of the adapter components in the related art, the present application greatly reduces the application cost. At the same time, the first control unit directly receives the charging control signal, reduces the intermediate processing and conversion process of the signal, reduces the failure points, strengthens the system stability, and reduces the system state, which is easy to manage.

[0092] It should be noted that due to the inconsistencies in physical shape, size, etc. between the Japanese standard and the national standard charging interface, this application does not consider changing the physical interface, and the changes to the interface will not be specifically explained in subsequent texts. The goal is to ensure compatibility with charging control.

[0093] Combine the following Figure 3 The charging control device of the embodiment of the present application is described in detail.

[0094] like Figure 3 As shown, the charging control device 100 according to the embodiment of the present application includes: a first pin 10 , a second pin 20 , a third pin 30 and a first control unit 40 .

[0095] Among them, the first control unit 40 is connected to the first pin 10, the second pin 20 and the third pin 30 respectively, and the first control unit 40 determines the current charging standard to be executed based on at least one of the detection signal of the first pin 10, the detection signal of the second pin 20 and the detection signal of the third pin 30.

[0096] Specifically, the charging control device 100 can be applied to vehicles, electric vehicles, energy storage systems and other devices that require charging operations, without limitation herein. The following takes the application of the charging control device in a vehicle as an example to describe the charging control device 100 of the present application in detail.

[0097] Among them, the first pin 10, the second pin 20 and the third pin 30 may have different actions under different charging standards, such as different functions, different action timings, different connection relationships, etc., to distinguish different charging standards. For example, the first pin 10 is used to receive a first voltage signal under the national charging standard and to receive a second voltage signal under the Japanese charging standard; the second pin 20 implements function A under the national charging standard and function B under the Japanese charging standard; the third pin 30 implements function C under the national charging standard and function D under the Japanese charging standard. Therefore, the detection signals of the first pin 10, the second pin 20 and the third pin 30 can be used to determine the function type currently executed by each pin to distinguish the currently executed charging standard.

[0098] That is to say, in order to achieve compatibility with multiple charging standards, the same pins of the charging control device 100 are connected to different charging interface signals when dealing with different charging methods; at the same time, the vehicle body ground is connected to different charging interface signals under different charging methods. Taking the charging control device 100 compatible with the national standard charging standard and the Japanese standard charging standard as an example, the pin connection relationship under different charging standards is summarized as shown in Table 1 below, where pins AF of the charging control device 100 are virtual codes and can be any pins in actual applications.

[0099] Table 1

[0100]

[0101] Among them, pin E and pin F are used for communication in both the Japanese charging standard and the national charging standard, and have the same function. Pin A is connected to the positive pole of the external power supply when the charging interface is connected in both the Japanese charging standard and the national charging standard, and can be used as the first pin 10 to identify whether the external power supply is input. In the Japanese charging standard and the international charging standard, the control timing or connection relationship of pin B and pin C is different. Therefore, pin B and pin C can be used as the second pin 20 and the third pin 30. When there is an external power supply input on pin A, the first control unit 40 determines the charging standard to be executed based on the detection signal on pin B and / or pin C, and performs charging control according to the determined charging standard.

[0102] It should be noted that there may be a preset mapping relationship between the detection signal of the corresponding pin and the charging standard, and the currently adopted charging standard is determined based on the acquired detection signal of the corresponding pin and the preset mapping relationship.

[0103] Therefore, this embodiment can determine the currently adopted charging standard based on the detection signal of the pin when an external power supply is input, and execute the corresponding charging control program according to the corresponding charging standard to achieve compatibility with multiple charging standards.

[0104] According to one embodiment of the present application, the first control unit 40 is further used to determine the current charging standard to be executed by identifying at least one of the external power supply input condition based on the detection signal of the first pin 10, identifying the trigger timing based on the detection signal of the second pin 20, and identifying the level size based on the detection signal of the third pin 30.

[0105] Specifically, the first pin 10 can be used to connect an external power supply under different charging standards to identify the external power supply input. The second pin 20 can have different action timings under different charging standards, and the triggering timing of the corresponding detection signal is different. The third pin 30 can have different connection relationships under different charging standards, and the level of the corresponding detection signal is different. During the charging control process, the state of each pin can be determined based on the detection signal of the first pin 10 to identify the external power supply input, the detection signal of the second pin 20 to identify the triggering timing, and the detection signal of the third pin 30 to identify the level, so as to distinguish the currently executed charging standard.

[0106] According to another embodiment of the present application, the first control unit 40 is further used to determine the current charging standard to be executed based on at least one of the detection signal of the second pin 20 and the detection signal of the third pin 30 when it is determined that there is an external power supply input based on the detection signal of the first pin 10.

[0107] Specifically, the first pin 10 can be used to connect an external power supply under different charging standards, and the second pin 20 and the third pin 30 have different actions under different charging standards, such as different functions, different action timings, different connection relationships, etc., so as to distinguish different charging standards. For example, the second pin 20 implements function A under the national charging standard and function B under the Japanese charging standard; the third pin 30 implements function C under the national charging standard and function D under the Japanese charging standard. Therefore, the function type currently executed by each pin can be determined based on one of the detection signals of the second pin 20 and the third pin 30 to distinguish the currently executed charging standard.

[0108] According to another embodiment of the present application, the first pin 10 is suitable for connecting to a first control signal port that complies with a second charging standard, the second pin 20 is suitable for connecting to a second control signal port that complies with the second charging standard, and the third pin 30 is suitable for connecting to a detection port that complies with the second charging standard.

[0109] Specifically, when the second charging standard is the Japanese charging standard, as shown in Table 1, the first control signal port is Charge sequence signal 1, and the second control signal port is Charge sequence signal 2, wherein Charge sequence signal 1 and Charge sequence signal 2 output control signals for characterizing process progress, and the detection port is Connector proximity detection, which is used to detect whether the interface is fully connected.

[0110] According to an embodiment of the present application, the first control unit 40 is further configured to determine a charging standard to be currently executed according to a triggering timing of a detection signal of the second pin 20 .

[0111] Specifically, combining Table 1 and Figure 4 As shown, the first pin 10 is pin A, and the second pin 20 is pin B.

[0112] When using the national standard charging standard, Figure 5 As shown, after the user inserts the gun and swipes the card, the off-board charger controller controls K3 and K4 to close at the same time to output A+ and A-, where the role of A+ and A- is that the national standard charging pile provides a low-voltage auxiliary power supply for the vehicle, which will be output simultaneously after the user inserts the gun and swipes the card, that is, the first pin 10 and the second pin 20 are triggered at the same time.

[0113] When using the Japanese charging standard, Figure 6 As shown in the figure, after the user inserts the gun and swipes the card, the Charge sequence signal 1 will be activated first, and then the charging pile will send the Charge sequence signal 2 activation after interaction with the vehicle, electric lock judgment, and insulation detection. Among them, Charge sequence signal 1 (corresponding to A+ in the international charging standard) and Charge sequence signal 2 (corresponding to A- in the international charging standard) are used to represent the progress of the process, not to power the vehicle. After the user inserts the gun and swipes the card, they will be output successively, that is, the first pin 10 and the second pin 20 are not triggered at the same time.

[0114] Therefore, in the national charging standard and the Japanese charging standard, although pin A and pin B receive high and low level signals, the meaning and triggering timing of the received signals are different in the two standards. Therefore, the current charging standard to be executed can be determined based on the triggering timing of the detection signal of the second pin 20.

[0115] According to one embodiment of the present application, the first control unit 40 is specifically used to determine that the charging standard currently to be executed is the first charging standard when the time difference of the detection signal between the first pin 10 and the second pin 20 is less than or equal to the first preset time threshold; and to determine that the charging standard currently to be executed is the second charging standard when the time difference of the detection signal between the first pin 10 and the second pin 20 is greater than the first preset time threshold.

[0116] Specifically, taking the first charging standard as the national charging standard and the second charging standard as the Japanese charging standard as an example, when the time difference of the detection signal between the first pin 10 and the second pin 20 is less than or equal to the first preset time threshold, it is considered that the first pin 10 and the second pin 20 are triggered simultaneously, and the signals received by the first pin 10 and the second pin 20 are used to provide a low-voltage auxiliary power supply to the vehicle, confirming that the current charging standard to be executed is the national charging standard;

[0117] When the time difference of the detection signal between the first pin 10 and the second pin 20 is greater than the first preset time threshold, it is considered that the first pin 10 and the second pin 20 are not triggered at the same time, and the signals received by the first pin 10 and the second pin 20 are used to characterize the progress of the process, and it is confirmed that the current charging standard to be executed is the Japanese standard charging standard. The first preset time threshold can be set according to actual conditions.

[0118] According to an embodiment of the present application, the first control unit 40 is further configured to determine a charging standard to be currently executed according to the level of the detection signal of the third pin 30 .

[0119] Specifically, as shown in Table 1, the first pin 10 is pin A, and the third pin 30 is pin C. The third pin 30 is used to identify whether a charging gun is connected. For different charging standards, the signal resistance of the charging gun is different. Therefore, when it is determined that the first pin 10 has an external power supply input, the level of the detection signal of the third pin 30 is obtained to determine the current charging standard to be executed.

[0120] It should be noted that the current charging standard to be executed can be determined directly by the level, or the resistance value of the connected resistor can be determined according to the obtained level, and the current charging standard to be executed can be determined according to the range of the resistance value. There is no limitation here.

[0121] According to one embodiment of the present application, the first control unit 40 is specifically used to determine that the charging standard to be executed is the first charging standard when the level of the detection signal of the third pin 30 is greater than or equal to the first preset level threshold; when the level of the detection signal of the third pin 30 is less than the first preset level threshold, determine that the charging standard to be executed is the second charging standard.

[0122] That is to say, this embodiment directly determines the current charging standard to be executed based on the level size. Taking the first charging standard as the national charging standard and the second charging standard as the Japanese charging standard as an example, when the level of the detection signal of the third pin 30 reaches the first preset level threshold, it is determined that the current charging standard to be executed is the national charging standard; when the level of the detection signal of the third pin 30 does not reach the first preset level threshold, it is determined that the current charging standard to be executed is the Japanese charging standard.

[0123] According to one embodiment of the present application, the first control unit 40 is specifically used to, when an external power supply input signal of the first pin 10 and a charging connection signal of the third pin 30 are detected, if it is detected that the input of the second pin 20 is not a low-level signal, determine that the current charging standard to be executed is the second charging standard; if it is detected that the input of the second pin 20 is a low-level signal, determine that the current charging standard to be executed is the first charging standard.

[0124] Specifically, taking the first charging standard as the national charging standard and the second charging standard as the Japanese charging standard as an example, when it is determined that the first pin 10 has an external power supply input and the third pin 30 has a charging connection signal, that is, the charging gun is successfully connected, if the second pin 20 input is not a low-level signal, the first pin 10 and the second pin 20 are not triggered at the same time, and the signals received by the first pin 10 and the second pin 20 are used to characterize the progress of the process, confirming that the current charging standard to be executed is the Japanese charging standard; if it is detected that the second pin 20 input is a low-level signal, the second pin 20 and the first pin 30 are triggered at the same time, and the signals received by the first pin 10 and the second pin 20 are used to provide a low-voltage auxiliary power supply to the vehicle, and it is determined that the current charging standard to be executed is the national charging standard.

[0125] In this embodiment, when an external power supply is input to the first pin 10 , the charging standard to be currently executed is determined based on the detection signal of the second pin 20 and the detection signal of the third pin 30 .

[0126] According to one embodiment of the present application, Figure 5 and Figure 6As shown, the first control unit 40 is specifically used for, when an external power supply input signal of the first pin 10 and a charging connection signal of the third pin 30 are detected, if it is determined according to the charging connection signal that the third pin 30 is connected to the first connection resistor R11, then the charging standard to be executed is determined to be the second charging standard; if it is determined according to the charging connection signal that the third pin 30 is connected to the second connection resistor R12, then the charging standard to be executed is determined to be the first charging standard, wherein the resistance value of the second connection resistor R12 is different from the resistance value of the first connection resistor R11, and can be specifically set based on actual conditions, for example, the first connection resistor R11 is 200Ω, and the second connection resistor R12 is 1KΩ.

[0127] Specifically, the third pin 30 is pin C in Table 1, and is used to determine whether a charging gun is connected.

[0128] Taking the first charging standard as the national charging standard and the second charging standard as the Japanese charging standard as an example, when the national standard charging pile is used to charge the vehicle, Figure 5 As shown, after the charging gun of the national standard charging pile is connected to the charging interface of the vehicle, it is connected to the battery pack based on DC+ and DC-, and is connected to each pin of the charging control device 100 based on the corresponding port, wherein the third pin 30 is connected to the second connection resistor R12 of the charging gun of the national standard charging pile; when the Japanese standard charging pile is used to charge the vehicle, Figure 6 As shown, after the charging gun of the Japanese standard charging pile is connected to the charging interface of the vehicle, it is connected to the battery pack based on DC+ and DC-, and is connected to each pin of the charging control device 100 based on the corresponding port, wherein the third pin 30 is connected to the first connection resistor R11 of the charging gun of the Japanese standard charging pile.

[0129] Therefore, when the external power supply input signal of the first pin 10 and the charging connection signal of the third pin 30 are detected, the size of the connected resistance can be judged based on the charging connection signal of the third pin 30, and when the connected resistance is judged to be the first connection resistance R11, it is determined that the current charging standard to be executed is the Japanese charging standard; when the connected resistance is judged to be the second connection resistance R12, it is determined that the current charging standard to be executed is the national charging standard, and then charging control is performed according to the determined charging standard.

[0130] In this embodiment, when an external power supply is input to the first pin 10 , the charging standard to be currently executed is determined based on the detection signal of the third pin 30 .

[0131] According to one embodiment of the present application, the third pin 30 is also connected to the first preset power supply U1 through the first pull-up resistor R13, and is suitable for connecting one end of the first connection resistor R11, wherein the other end of the first connection resistor R11 is connected to the protective ground; or is suitable for connecting one end of the second connection resistor R12, wherein the other end of the second connection resistor R12 is connected to the vehicle body ground.

[0132] Specifically, taking the first charging standard as the national charging standard and the second charging standard as the Japanese charging standard as an example, when the Japanese charging pile is used to charge the vehicle, Figure 6 As shown, the first connection resistor R11 and the first pull-up resistor R13 divide the voltage of the first preset power supply U1, and the first control unit 40 obtains the divided voltage of the detection point 2 through the detection point 2; when the national standard charging pile is used to charge the vehicle, Figure 5 As shown, the second connection resistor R12 and the first pull-up resistor R13 divide the voltage of the first preset power supply U1, and the first control unit 40 obtains the divided voltage of the detection point 2 through the detection point 2. The divided voltage of the detection point 2 is the voltage of the third pin 30. Therefore, the first control unit 40 can determine the connection resistor connected to the third pin 30 based on the voltage size of the third pin 30, and then determine that the current charging standard to be executed is the national standard charging standard.

[0133] According to one embodiment of the present application, Figure 5 and Figure 6 As shown, the charging control device 100 also includes: a fourth pin 50, the fourth pin 50 is connected to the first control unit 40 through the first resistor R21, wherein, when the current charging standard to be executed is the second charging standard, the first control unit 40 grounds the first resistor R21; when the current charging standard to be executed is the first charging standard, the first control unit 40 suspends the first resistor R21.

[0134] Specifically, the charging control device 100 is additionally provided with a fourth pin 50 and a first resistor R21 . As shown in Table 1, the fourth pin 50 is the pin D in Table 1.

[0135] Taking the first charging standard as the national charging standard and the second charging standard as the Japanese charging standard as an example, the first resistor R21 is initially set to be in a disconnected and suspended state. When the detection signal of the second pin 20 and / or the third pin 30 determines that the current charging standard to be executed is the Japanese charging standard, when the vehicle is allowed to charge, the first control unit 40 controls the first resistor R21 to be grounded, triggering the fourth pin 50 to be valid; when the detection signal of the second pin 20 and / or the third pin 30 determines that the current charging standard to be executed is the national charging standard, the first control unit 40 keeps the first resistor R21 in a disconnected and suspended state, and the fourth pin 50 is invalid, so as to meet the requirements of different charging standards.

[0136] According to one embodiment of the present application, the fourth pin 50 is further suitable for being connected to a CC1 port conforming to the second charging standard; or being connected to the vehicle body ground through a second resistor R22 and being connected to a CC1 port conforming to the first charging standard.

[0137] Specifically, taking the first charging standard as the national charging standard and the second charging standard as the Japanese charging standard as an example, when the Japanese charging standard is adopted, the CC1 port is the port corresponding to the Vehicle charge permission signal in Table 1. When it is determined that the current charging standard to be executed is the Japanese charging standard, when it is determined according to the interaction timing that the vehicle is allowed to charge, the first control unit 40 controls the first resistor R21 to be grounded, triggering the fourth pin 50 to be effective; when it is determined that the current charging standard to be executed is the national charging standard, the first control unit 40 keeps the first resistor R21 in a disconnected and suspended state, and the CC1 port of the national charging standard is connected to the vehicle body ground through the second resistor R22 to avoid affecting the CC1 detection of the national standard charging pile based on detection point 1.

[0138] In one embodiment of the present application, the first pin 10 , the second pin 20 , the third pin 30 and the fourth pin 50 are configured in a connector.

[0139] Specifically, in order to better achieve the switching between charging methods compatible with different standards, the docking relationship of each pin is fixed by a connector, such as Figure 7 As shown, when switching between national standard charging and Japanese standard charging, it is only necessary to simply replace the charging socket and its low-voltage connector. For example: when connector 1 is plugged in, A+ is connected to pin A, i.e., the first pin 10, and A- is connected to pin B, i.e., the second pin 20; when connector 2 is plugged in, charge sequence signal 1 is connected to pin A, i.e., the first pin 10, and charge sequence signal 2 is connected to pin B, i.e., the second pin 20.

[0140] Furthermore, this application makes as few changes as possible based on the national standard version of BMS, and obtains the control guidance circuits for national standard charging and Japanese standard charging, as shown in the attached Figure 5 and Figure 6 shown.

[0141] In order to support the charging control solution of this application to achieve compatibility between the Chinese and Japanese standards, i.e., the first charging standard and the second charging standard, the following specific requirements are placed on the hardware solution:

[0142] 1. The first pin 10 and the second pin 20 use independent sampling for A+ / Charge sequence signal 1 and A- / Charge sequence signal 2 to ensure that the access status of A+ / Charge sequence signal 1 and A- / Charge sequence signal 2 can be judged in real time;

[0143] 2. The hardware adds a vehicle charge permission control pin to control the first resistor R21. That is, when charging according to the national standard (the first charging standard), there is no need to control it to remain in a suspended state. When charging according to the Japanese standard (the second charging standard), it must be grounded as required.

[0144] In summary, according to the charging control device of the embodiment of the present application, the first control unit is connected to the first pin, the second pin and the third pin respectively. When the first control unit recognizes the input of the external power supply through the first pin, it determines the current charging standard to be executed based on at least one of the detection signal of the second pin and the detection signal of the third pin. When the first pin has an external power supply input, the charging control device determines the charging standard according to the detection signal of the second pin and / or the detection signal of the third pin, and performs charging according to the determined charging standard, thereby being compatible with multiple charging standards. Compared with the application of the adapter component in the related art, the present application greatly reduces the application cost.

[0145] Corresponding to the above embodiments, the present application also proposes a vehicle charging interface assembly.

[0146] like Figure 8 As shown, the vehicle charging interface assembly 200 of the embodiment of the present application includes a first pin 10 , a second pin 20 and a third pin 30 .

[0147] Among them, the first pin 10 is suitable for connecting the power pin 210 of the external power supply. The second pin 20 is suitable for connecting the ground pin 220 of the external power supply. The third pin 30 is suitable for connecting the plug pin 230 of the external charging pile. When the first pin 10 and the third pin 30 are recognized by the vehicle controller 400 as the external power supply is connected and the charging gun is inserted, the type of the external charging pile is determined based on at least one of the high and low level signals of the second pin 20 and the resistance signal of the third pin 30.

[0148] Specifically, in combination with Table 1, when the national standard charging standard is adopted, the power pin 210 of the external power supply corresponds to A+ in Table 1, the ground pin 220 of the external power supply corresponds to A- in Table 1, and the plug-in pin 230 of the external charging pile corresponds to CC2 in Table 1, wherein the function of A+ and A- is that the national standard charging pile provides a low-voltage auxiliary power supply for the vehicle, which will be output simultaneously after the user inserts the gun and swipes the card, that is, the first pin 10 and the second pin 20 are triggered simultaneously. When the Japanese standard charging standard is adopted, the power pin 210 of the external power supply corresponds to the Charge sequence signal 1 in Table 1, the ground pin 220 of the external power supply corresponds to the Charge sequence signal 2 in Table 1, and the plug-in pin 230 of the external charging pile corresponds to the Connectorproximity detection in Table 1, wherein, after the user inserts the gun and swipes the card, the Charge sequence signal 1 will be activated first, and then the charging pile will send the Charge sequence signal 2 activation after the interaction with the vehicle, the electric lock judgment, and the insulation detection. Among them, Charge sequence signal 1 and Charge sequence signal 2 are used to characterize the progress of the process, not to power the vehicle. They will be output successively after the user inserts the gun and swipes the card, that is, the first pin 10 and the second pin 20 are not triggered at the same time.

[0149] Therefore, in the national charging standard and the Japanese charging standard, although pin A and pin B receive high and low level signals, the meaning and triggering timing of the received signals are different in the two standards. Therefore, the type of the currently connected external charging pile can be determined based on the triggering timing of the detection signal of the second pin 20.

[0150] The third pin 30 is used to identify whether a charging gun is connected. For different charging standards, the signal resistance of the charging gun connection is different. Therefore, when it is determined that the first pin 10 has an external power supply input, the resistance signal of the third pin 30 is obtained to determine the type of external charging pile currently connected.

[0151] In this embodiment, when it is determined that an external power supply is connected based on the detection signal of the first pin 10 and a charging gun is inserted based on the detection signal of the third pin 30, the type of the external charging pile can be determined according to the high and low level signals of the second pin 20, or according to the resistance signal of the third pin 30. The type of the external charging pile can also be determined by the high and low level signals of the second pin 20 and the resistance signal of the third pin 30. There is no limitation here, and then the corresponding charging standard is determined according to the determined charging pile type, and charging control is performed with the corresponding charging standard.

[0152] According to one embodiment of the present application, when the first pin 10 and the third pin 30 are recognized by the vehicle controller 400 that the external power supply is connected and the charging gun is inserted, if the second pin 20 inputs a low-level signal, the external charging pile is the first charging pile; if the second pin 20 does not input a low-level signal, the external charging pile is the second charging pile.

[0153] That is to say, taking the first charging pile as a national standard charging pile and the second charging pile as a Japanese standard charging pile as an example, when it is determined that the first pin 10 has an external power supply input, and the third pin 30 has a charging connection signal, that is, the charging gun is successfully connected, if it is detected that the second pin 20 input is a low-level signal, the second pin 20 and the first pin 30 are triggered at the same time, and the signals received by the first pin 10 and the second pin 20 are used to provide a low-voltage auxiliary power supply to the vehicle, confirming that the currently connected external charging pile is a national standard charging pile. If the second pin 20 does not input a low-level signal, the first pin 10 and the second pin 20 are not triggered at the same time, and the signals received by the first pin 10 and the second pin 20 are used to characterize the progress of the process, confirming that the currently connected external charging pile is a Japanese standard charging pile.

[0154] According to one embodiment of the present application, when the first pin 10 and the third pin 30 are recognized by the vehicle controller 400 as being connected to an external power supply and a charging gun being inserted, if it is determined that the third pin 30 is connected to a first connection resistor based on a gun insertion signal of the third pin 30, the external charging pile is a second charging pile; if it is determined that the third pin 30 is connected to a second connection resistor based on a gun insertion signal of the third pin 30, the external charging pile is a first charging pile, wherein the resistance value of the second connection resistor is different from the resistance value of the first connection resistor, and can be specifically set according to actual conditions, for example, the resistance value of the second connection resistor is greater than the resistance value of the first connection resistor.

[0155] That is to say, for different charging standards, the resistance value of the resistor connected to the charging gun is different. Therefore, when the external power supply is connected and the charging gun is inserted, the connection resistance connected to the third pin 30 can be determined based on the plug-in signal of the third pin 30, and then the type of the external charging pile connected can be determined based on the different connection resistances. Specifically, the connection resistance connected to the third pin 30 can be determined by pre-establishing a mapping relationship between the level of the plug-in signal and the resistance value of the connection resistance.

[0156] According to one embodiment of the present application, the third pin 30 is also suitable for connecting to a first preset power supply through a first pull-up resistor, and is also suitable for connecting to one end of the first connection resistor, wherein the other end of the first connection resistor is connected to the protective ground; or is suitable for connecting to one end of the second connection resistor, wherein the other end of the second connection resistor is connected to the vehicle body ground.

[0157] Specifically, when a Japanese standard charging pile is used to charge the vehicle, the first connection resistor and the first pull-up resistor divide the first preset power supply to obtain a corresponding plug-in signal; when a national standard charging pile is used to charge the vehicle, the second connection resistor and the first pull-up resistor divide the first preset power supply to obtain a corresponding plug-in signal. Therefore, the connection resistor connected to the third pin 30 can be determined based on the plug-in signal of the third pin 30, and then the type of external charging pile connected can be determined.

[0158] According to one embodiment of the present application, Fig. 9 As shown, the vehicle charging interface assembly 200 also includes: a fourth pin 50, the fourth pin 50 is suitable for being connected to the vehicle controller 400 through the first resistor R21, and being connected to the vehicle body ground through the second resistor R22, the first resistor R11 and the second resistor R21 have the same resistance value, wherein, when the external charging pile is the second charging pile, the vehicle controller 400 connects the first resistor R21 to the ground; when the external charging pile is the first charging pile, the vehicle controller 400 suspends the first resistor R21.

[0159] That is to say, the vehicle charging interface assembly 200 is additionally provided with a fourth pin 50 and a first resistor R21 and a second resistor R22. As shown in Table 1, the fourth pin 50 is the pin D in Table 1.

[0160] Taking the first charging pile as a national standard charging pile and the second charging pile as a Japanese standard charging pile as an example, the first resistor is initially set to be in a disconnected and suspended state. When it is determined that the external charging pile is a Japanese standard charging pile, when the vehicle is allowed to charge, the first control unit 40 controls the first resistor R21 to be grounded, triggering the fourth pin 50 to be valid; when it is determined that the external charging pile is a national standard charging pile, the first control unit 40 keeps the first resistor R21 in a disconnected and suspended state, and the fourth pin 50 is invalid, so as to meet different charging standard requirements.

[0161] According to one embodiment of the present application, the vehicle charging interface assembly further includes a connector, wherein the first pin 10, the second pin 20, the third pin 30 and the fourth pin 50 are configured in the connector. That is, in order to better achieve the switching between charging methods compatible with different standards, the connector is used to fix the docking relationship of each pin.

[0162] It should be noted that for details not disclosed in the vehicle charging interface assembly of the embodiment of the present application, please refer to the details disclosed in the charging control device of the above embodiment of the present application, and the details will not be repeated here.

[0163] According to the vehicle charging interface assembly of the embodiment of the present application, the first pin is suitable for connecting the power pin of the external power supply, the second pin is suitable for connecting the ground pin of the external power supply, and the third pin is suitable for connecting the plug pin of the external charging pile. When the first pin and the third pin are identified by the vehicle controller as the external power supply is connected and the charging gun is inserted, the type of the external charging pile is determined based on at least one of the high and low level signals of the second pin and the resistance signal of the third pin. When the first pin has an external power supply input, the charging interface assembly determines the type of the external charging pile based on at least one of the high and low level signals of the second pin and the resistance signal of the third pin, and determines the charging standard based on the type of the external charging pile, and then performs the charging operation. Therefore, the charging interface assembly can be compatible with multiple types of charging piles. Compared with the application of adapter components in the related art, the present application greatly reduces the application cost.

[0164] Corresponding to the above embodiment, the present application also proposes a charging control steering circuit.

[0165] like Fig.10 As shown, the charging control steering circuit 300 of the embodiment of the present application includes: a power supply connection unit 310, a first charging confirmation unit 320 and a vehicle controller 400.

[0166] The power supply connection unit 310 is used to establish a DC power supply connection with an external charging pile. The first charging confirmation unit 320 is used to confirm whether the charging gun of the external charging pile is inserted. The vehicle controller 400 is used to determine the type of the external charging pile based on at least one of the ground connection signal of the power supply connection unit 310 and the plug-in signal of the first charging confirmation unit 320 when the DC power supply signal of the power supply connection unit 310 is detected, and execute the corresponding charging standard according to the type of the external charging pile.

[0167] According to one embodiment of the present application, the power supply connection unit 310 includes a first pin and a second pin, and the first pin and the second pin are suitable for connecting to a DC power supply of an external charging pile through a first switch and a second switch respectively.

[0168] According to one embodiment of the present application, the vehicle controller 400 is also used to determine that the external charging pile is a first charging pile when a DC power supply signal and a ground connection signal are detected simultaneously through the first pin and the second pin; and to determine that the external charging pile is a second charging pile when a DC power supply signal and a ground connection signal are detected successively through the first pin and the second pin.
