[0081] Embodiments of the present disclosure are described in detail below with reference to the accompanying drawings, in which the same or like reference numerals in different drawings denote the same or like 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 explain the present disclosure, and cannot be understood as limiting the present disclosure.

[0082] The charging control device, the vehicle charging interface assembly, the charging control guide circuit, the charging control method, the computer readable storage medium, the vehicle controller and the vehicle proposed by the embodiments of the present disclosure are described below with reference to the accompanying drawings.

[0083] With the development of electric vehicles, more and more export models are available. In order to meet the demand of export market, vehicles need to realize JIS DC charging.

[0084] In the related art, a conversion module, such as an electric vehicle communication controller (EVCC), is installed on a GB (complying with Chinese national standard GB / T 20234) DC charging vehicle to realize JIS (such as complying with Japanese charging standard CHAdeMO) DC charging. The conversion module converts the JIS signal into a GB signal according to the received JIS signal after a certain logical judgment, and outputs the GB signal, and other controls in the vehicle remain unchanged in the GB state.

[0085] Based on the above scheme, the day standard charging vehicle type is installed on the national standard charging vehicle type, and other control modules such as the battery management system (BMS) of the vehicle can remain in a unified state.

[0086] The day standard direct current charging scheme in the related art is shown in FIG. 1, and the national standard direct current charging scheme is shown in FIG. 2. Among them, CHAdeMO refers to the day standard charging standard, EVCC realizes the conversion between the signals of the day standard charging standard and the signals of the national standard charging standard, and then outputs the signals meeting the national standard charging standard to the BMS of the vehicle, so that the BMS of the vehicle can continue to perform charging control according to the national standard charging standard. Among them, the national standard BMS refers to the BMS performing charging control according to the national standard charging standard.

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

[0088] ①EVCC is developed as an independent controller, resulting in a relatively large increase in the cost of the day standard charging vehicle;

[0089] ②In the case of using the day standard charging standard, the charging control signal needs to be processed and converted by the EVCC before being transmitted to the main controller (i.e., the national standard BMS), increasing the system failure probability and reducing the stability;

[0090] ③In the case of installing EVCC on the day standard charging vehicle type, the vehicle control system still has multiple states of the day standard and the national standard, which is not convenient for management.

[0091] To solve the above technical problems, some embodiments of the present disclosure provide a charging control device. In the charging control device, a first controller is connected with a first pin, a second pin and a third pin respectively, and the first controller determines the current charging standard to be executed based on at least one of the detection signals of the first pin, the second pin and the third pin. The charging control device can determine the charging standard according to one or more of the detection signals of the first pin, the detection signals of the second pin and the detection signals of the third pin, and execute charging according to the determined charging standard, thereby being compatible with multiple charging standards. Compared with the application of the adapter component (such as EVCC) in the related art, the application cost is greatly reduced in some embodiments of the present disclosure. Moreover, the first controller can directly receive the charging control signal, reducing the intermediate processing and conversion process of the signal, thereby reducing the failure points, improving the system stability, and reducing the system state, which is convenient for management.

[0092] It should be noted that, because the day standard and the national standard charging interfaces are inconsistent in physical shape, size, etc., the physical interface is not considered to be changed in the present disclosure, and the change of the interface will not be specifically described in the subsequent text. The goal is to be compatible with charging control.

[0093] The charging control device of some embodiments of the present disclosure will be described in detail below in combination with FIG. 3.

[0094] As shown in FIG. 3, the charging control device 100 of some embodiments of the present disclosure includes a first pin 10, a second pin 20, a third pin 30, and a first controller 40.

[0095] The first controller 40 is connected to the first pin 10, the second pin 20, and the third pin 30 respectively. The first controller 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. Here, "at least one of A, B, and C" has the same meaning as "at least one of A, B, or C", which includes the following combinations of A, B, and C: only A, only B, only C, a combination of A and B, a combination of A and C, a combination of B and C, and a combination of A, B, and C.

[0096] For example, the charging control device 100 can be applied in devices that need charging operation, such as vehicles, electric vehicles, energy storage systems, etc., without limitation. The charging control device 100 of some embodiments of the present disclosure will be described in detail below taking the application of the charging control device in vehicles as an example.

[0097] The first pin 10, the second pin 20, and the third pin 30 can have different actions under different charging standards, such as different functions, different action timings, different connection relationships, etc., for distinguishing different charging standards. For example, the first pin 10 is used to receive a first voltage signal under the national standard charging standard and is used to receive a second voltage signal under the Japanese standard charging standard; the second pin 20 realizes function A under the national standard charging standard and realizes function B under the Japanese standard charging standard; and the third pin 30 realizes function C under the national standard charging standard and realizes function D under the Japanese standard charging standard. Thus, the type of function currently executed by each pin can be determined according to the detection signal of the first pin 10, the second pin 20, and the third pin 30, so as to distinguish the charging standard currently executed.

[0098] That is, in order to realize the compatibility of multiple charging standards, the same pin of the charging control device 100 corresponds to different charging interface signals when dealing with different charging modes, and the vehicle body is connected to different charging interface signals under different charging modes. 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 shown in Table 1 below. Among them, the pins A-F of the charging control device 100 are virtual codes, which can be any pin in actual application.

[0099] Table 1

[0100] The pin E and the pin F are used for communication in the Japanese charging standard and the Chinese charging standard, and have the same function. The pin A is connected to the charging interface in the Japanese charging standard and the Chinese charging standard, and is connected to the positive pole of the external power supply, 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 the connection relationship of the pin B and the pin C are different, and therefore the pin B and the pin C can be used as the second pin 20 and the third pin 30. The first controller 40 determines the charging standard to be executed based on the detection signal of at least one of the pin B and the pin C in the case that the external power supply is input on the pin A, and performs the charging control according to the determined charging standard.

[0101] It should be noted that the preset mapping relationship between the detection signal of the corresponding pin and the charging standard can be pre-stored, and the charging standard currently used is determined based on the acquired detection signal of the corresponding pin and the preset mapping relationship.

[0102] Therefore, the embodiment can determine the charging standard currently used based on the detection signal of the pin in the case that the external power supply is input, and perform the corresponding charging control program according to the corresponding charging standard, so as to realize the compatibility of multiple charging standards.

[0103] In some embodiments, the first controller 40 is further configured to determine the charging standard to be executed in at least one of the following cases: identifying the input of the external power supply 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. It should be noted that the use of “adapted to” or “configured to” in this document means open and inclusive language, which does not exclude devices adapted to or configured to perform additional tasks or steps.

[0104] For example, the first pin 10 can be used to connect the external power supply under different charging standards to identify the input of the external power supply. The second pin 20 can have different action timing under different charging standards, and the trigger timing of the corresponding detection signal of the second pin 20 is different under different charging standards. The third pin 30 can have different connection relationships under different charging standards, and the level size of the corresponding detection signal of the third pin 30 is different under different charging standards. In 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 input of the external power supply, the detection signal of the second pin 20 to identify the trigger timing, and the detection signal of the third pin 30 to identify the level size, so as to distinguish the charging standard currently executed.

[0105] In some embodiments, the first controller 40 is further configured to determine the charging standard to be performed currently according to at least one of the detection signal of the second pin 20 and the detection signal of the third pin 30, in a case that it is determined that the external power supply input exists based on the detection signal of the first pin 10.

[0106] For example, the first pin 10 can be used to connect the 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 having different functions, having different action timings, having different connection relationships, etc., for distinguishing different charging standards.

[0107] For example, the second pin 20 implements function A under the national standard charging standard and implements function B under the Japanese standard charging standard, and the third pin 30 implements function C under the national standard charging standard and implements function D under the Japanese standard charging standard. Thus, the type of function currently performed by each pin can be determined based on the detection signal of at least one of the second pin 20 and the third pin 30, so as to distinguish the charging standard to be performed currently.

[0108] In some embodiments, the first pin 10 is adapted to connect a first control signal port conforming to a second charging standard, the second pin 20 is adapted to connect a second control signal port conforming to the second charging standard, and the third pin 30 is adapted to connect a detection port conforming to the second charging standard.

[0109] For example, when the second charging standard is the Japanese standard charging standard, in combination with Table 1, the first control signal port is Charge sequence signal 1, and the second control signal port is Charge sequence signal 2. Charge sequence signal 1 and Charge sequence signal 2 output control signals for representing the progress of the process. The detection port is Connector proximity detection, which is used to detect whether the interface is completely connected.

[0110] In some embodiments, the first controller 40 is further configured to determine the charging standard to be performed currently according to the triggering time of the detection signal of the second pin 20.

[0111] For example, in combination with Table 1 and FIG. 4, the first pin 10 is pin A, and the second pin 20 is pin B.

[0112] In the case of the national standard charging standard, as shown in FIG. 5, after the user inserts the gun and swipes the card, the non-vehicle-mounted charger controller controls the switch K3 and the switch K4 to be closed at the same time, so as to output the A+ and A- signals. The functions of A+ and A- are to provide low-voltage auxiliary power for the vehicle by the national standard charging pile. After the user inserts the gun and swipes the card, A+ and A- will output signals at the same time, that is, the first pin 10 and the second pin 20 are triggered at the same time.

[0113] In the case of the Japanese standard charging standard, as shown in FIG. 6, after the user inserts the gun and swipes the card, first, the Charge sequence signal 1 is activated, and then after the vehicle interaction, the lock judgment, and the insulation detection, the charging pile is activated Charge sequence signal 2. The signals output by 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, rather than to provide power to the vehicle. After the user inserts the gun and swipes the card, Charge sequence signal 1 and Charge sequence signal 2 will output signals in turn, that is, the first pin 10 and the second pin 20 are triggered at different times.

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

[0115] In some embodiments, the first controller 40 is configured to: in the case that the time difference of the detection signals between the first pin 10 and the second pin 20 is less than or equal to a first preset time threshold, determine that the current charging standard to be executed is the first charging standard; in the case that the time difference of the detection signals between the first pin 10 and the second pin 20 is greater than the first preset time threshold, determine that the current charging standard to be executed is the second charging standard.

[0116] For example, taking the first charging standard as the national standard charging standard and the second charging standard as the Japanese standard charging standard as an example, when the time difference of the detection signals 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 at the same time, and then the signals received by the first pin 10 and the second pin 20 are used to provide low-voltage auxiliary power for the vehicle, so as to confirm that the current charging standard to be executed is the national standard charging standard.

[0117] In a case where the time difference of the detection signals between the first pin 10 and the second pin 20 is greater than a first preset time threshold, it is considered that the first pin 10 and the second pin 20 are triggered at different times, and the signals received by the first pin 10 and the second pin 20 are used to represent the progress of the process, so as to confirm that the charging standard to be executed at present is the daily standard charging standard. The first preset time threshold can be set according to actual conditions.

[0118] In some embodiments, the first controller 40 is further configured to determine the charging standard to be executed at present according to the level of the detection signal of the third pin 30.

[0119] For example, in combination with 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 there is a charging gun connected. For different charging standards, the signals emitted by the connected charging guns correspond to different resistances, so that in a case where 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 charging standard to be executed at present.

[0120] It should be noted that the charging standard to be executed at present can be directly determined according to the level, or the resistance value of the connected resistance can be determined according to the obtained level, and the charging standard to be executed at present can be determined according to the range in which the resistance value is located, which is not limited here.

[0121] In some embodiments, the first controller 40 is configured to determine that the charging standard to be executed at present is a first charging standard in a case where the level of the detection signal of the third pin 30 is greater than or equal to a first preset level threshold, and determine that the charging standard to be executed at present is a second charging standard in a case where the level of the detection signal of the third pin 30 is less than the first preset level threshold.

[0122] That is, this embodiment directly determines the charging standard to be executed at present according to the level. Taking the first charging standard as the national standard charging standard and the second charging standard as the daily standard charging standard as an example, in a case where the level of the detection signal of the third pin 30 reaches (i.e., is greater than or equal to) the first preset level threshold, it is determined that the charging standard to be executed at present is the national standard charging standard, and in a case where the level of the detection signal of the third pin 30 does not reach (i.e., is less than) the first preset level threshold, it is determined that the charging standard to be executed at present is the daily standard charging standard.

[0123] In some embodiments, the first controller 40 is configured to, in the case of detecting the external power supply input signal of the first pin 10 and the charging connection signal of the third pin 30, determine that the current charging standard to be executed is the second charging standard if it is detected that the signal input from the second pin 20 is not a low-level signal (e.g., the signal is a high-level signal); and determine that the current charging standard to be executed is the first charging standard if it is detected that the signal input from the second pin 20 is a low-level signal.

[0124] For example, taking the case that the first charging standard is the national standard charging standard and the second charging standard is the Japanese standard charging standard, in the case of determining that the first pin 10 has an external power supply input and the third pin 30 has a charging connection signal (i.e., the charging gun is successfully connected), if the signal input from the second pin 20 is not a low-level signal, the first pin 10 and the second pin 20 are triggered at different times, and the signals received by the first pin 10 and the second pin 20 are used to represent the progress of the process, thereby confirming that the current charging standard to be executed is the Japanese standard charging standard. If it is detected that the signal input from the second pin 20 is a low-level signal, the second pin 20 is triggered at the same time as the first pin 30, 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, thereby determining that the current charging standard to be executed is the national standard charging standard.

[0125] This embodiment determines the current charging standard to be executed based on the detection signal of the second pin 20 and the detection signal of the third pin 30 in the case of the first pin 10 having an external power supply input.

[0126] In some embodiments, as shown in FIGS. 5 and 6, the first controller 40 is configured to, in the case of detecting the external power supply input signal of the first pin 10 and the charging connection signal of the third pin 30, determine that the current charging standard to be executed is the second charging standard if it is determined from the charging connection signal that the third pin 30 is connected to the first connection resistor R11; and determine that the current charging standard to be executed is the first charging standard if it is determined from the charging connection signal that the third pin 30 is connected to the second connection resistor R12. The resistance value of the second connection resistor R12 is different from the resistance value of the first connection resistor R11, which can be set based on actual conditions. For example, the first connection resistor R11 is 200Ω, and the second connection resistor R12 is 1KΩ.

[0127] For example, the third pin 30 is the pin C in Table 1, which is used to determine whether the charging gun is connected.

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

[0129] Therefore, in the case that the external power supply input signal of the first pin 10 and the charging connection signal of the third pin 30 are detected, the resistance value of the connected resistor can be determined based on the charging connection signal of the third pin 30. In the case that the connected resistor is determined to be the first connection resistor R11, it is determined that the charging standard to be executed at present is the Japanese standard charging standard; in the case that the connected resistor is determined to be the second connection resistor R12, it is determined that the charging standard to be executed at present is the national standard charging standard. Then, the charging control is executed according to the determined charging standard.

[0130] In this embodiment, in the case that the first pin 10 has an external power supply input, the charging standard to be executed at present is determined based on the detection signal of the third pin 30.

[0131] In some embodiments, as shown in FIG. 6, the charging control device 100 further comprises a first pull-up resistor R13 and a first preset power supply U1. The third pin 30 is further connected to the first preset power supply U1 through the first pull-up resistor R13. Moreover, the third pin 30 is further adapted to connect one end of the first connection resistor R11, and the other end of the first connection resistor R11 is connected to the protection ground (such as the vehicle body ground). Alternatively, the third pin 30 is further adapted to connect one end of the second connection resistor R12, and the other end of the second connection resistor R12 is connected to the vehicle body ground.

[0132] For example, the first charging standard is the national standard charging standard, and the second charging standard is the Japanese standard charging standard. As shown in FIG. 6, when the vehicle is charged by the Japanese standard charging pile, the first connection resistor R11 and the first pull-up resistor R13 are used to divide the voltage of the first preset power supply U1, and the first controller 40 obtains the voltage at the detection point 2. As shown in FIG. 5, when the vehicle is charged by the national standard charging pile, the second connection resistor R12 and the first pull-up resistor R13 are used to divide the voltage of the first preset power supply U1, and the first controller 40 obtains the voltage at the detection point 2. Since the voltage at the detection point 2 is the voltage of the third pin 30, the first controller 40 can determine the connection resistor connected to the third pin 30 based on the voltage of the third pin 30, and then determine that the current charging standard to be executed is the national standard charging standard.

[0133] In some embodiments, as shown in FIG. 5 and FIG. 6, the charging control device 100 further comprises a fourth pin 50. The fourth pin 50 is connected to the first controller 40 through a first resistor R21. In the case that the current charging standard to be executed is the second charging standard, the first controller 40 grounds the first resistor R21; in the case that the current charging standard to be executed is the first charging standard, the first controller 40 leaves the first resistor R21 floating.

[0134] For example, the charging control device 100 further comprises a fourth pin 50 and a first resistor R21. In combination with Table 1, the fourth pin 50 is the pin D in Table 1.

[0135] For example, the first charging standard is the national standard charging standard, and the second charging standard is the Japanese standard charging standard. Initially, the first resistor R21 is in a disconnected floating state (i.e., the first resistor R21 is floating), in the case that the current charging standard to be executed is determined to be the Japanese standard charging standard based on the detection signal of at least one of the second pin 20 and the third pin 30, when the vehicle is allowed to be charged, the first controller 40 grounds the first resistor R21 to trigger the fourth pin 50 to be effective; in the case that the current charging standard to be executed is determined to be the national standard charging standard based on the detection signal of at least one of the second pin 20 and the third pin 30, the first controller 40 keeps the first resistor R21 in the disconnected floating state, and the fourth pin 50 is ineffective. In this way, the charging standard requirements of different countries can be met.

[0136] It should be noted that the pin floating can be understood as that the pin is not connected to any signal, and the pin is neither connected to a high level nor connected to a low level.

[0137] In some embodiments, the fourth pin 50 is further adapted to be connected to a CC1 port meeting the second charging standard, or connected to a vehicle body ground through a second resistor R22 and connected to a CC1 port meeting the first charging standard.

[0138] For example, the first charging standard is the national standard charging standard, and the second charging standard is the Japanese standard charging standard. In the case of the Japanese standard charging standard, the CC1 port is the Vehicle charge permission port in Table 1. In the case where it is determined that the charging standard to be executed at present is the Japanese standard charging standard, when it is determined that the vehicle is allowed to charge according to the interaction timing, the first controller 40 controls the first resistor R21 to be grounded, triggering the fourth pin 50 to be active. In the case where it is determined that the charging standard to be executed at present is the national standard charging standard, the first controller 40 keeps the first resistor R21 in the open state, and the CC1 port of the national standard charging standard is connected to the vehicle body ground through the second resistor R22, so as to avoid affecting the detection of the CC1 of the national standard charging pile based on the detection point 1.

[0139] In some embodiments, the charging control device 100 further comprises a connector, and the first pin 10, the second pin 20, the third pin 30 and the fourth pin 50 are arranged in the connector.

[0140] For example, in order to better realize the switching between charging modes of different standards, the connection relationship of the pins is fixed through the connector. As shown in FIG. 7, when the national standard charging and the Japanese standard charging are switched, the charging socket and the low-voltage connector of the charging socket need to be simply replaced. For example, when the connector 1 is plugged in, A+ is connected to the pin A (i.e., the first pin 10), and A- is connected to the pin B (i.e., the second pin 20). When the connector 2 is plugged in, Charge sequence signal 1 is connected to the pin A (i.e., the first pin 10), and Charge sequence signal 2 is connected to the pin B (i.e., the second pin 20). Here, the pin A, the pin B and the pin C are arranged in the connector 3.

[0141] The charging control device 100 in some embodiments of the present disclosure makes as few changes as possible based on the national standard BMS, thereby obtaining the control guide circuit when the national standard charging and the Japanese standard charging, as shown in FIGS. 5 and 6, respectively.

[0142] In order to enable the charging control scheme of some embodiments of the present disclosure to realize the compatibility of the Chinese and Japanese standards, i.e., the first charging standard and the second charging standard, the following requirements are made on the hardware scheme:

[0143] 1. Independent sampling is adopted for the first pin 10 for A+ or Charge sequence signal 1, and the second pin 20 for A- or Charge sequence signal 2, so as to ensure that the connection states of A+ or Charge sequence signal 1, A- or Charge sequence signal 2 can be judged in real time.

[0144] 2、hardware increases Vehicle charge permission control pin, to control the first resistor R21, that is, in the national standard (the first charging standard) charging, the first resistor R21 is not needed to be controlled, the first resistor R21 keeps the state of suspension, in the Japanese standard (the second charging standard) charging, it is needed to act according to the demand, that is, the first resistor R21 is grounded.

[0145] In summary, according to the charging control device of some embodiments of the present disclosure, the first controller is connected with the first pin, the second pin and the third pin respectively, and the first controller 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 in the case that the external power supply input is identified through the first pin. The charging control device determines the charging standard according to at least one of the detection signal of the second pin and the detection signal of the third pin in the case that the external power supply input is in the first pin, and executes the charging with the determined charging standard, thereby being compatible with multiple charging standards. Compared with the application of the adapter component in the related art, the charging control device 100 in some embodiments of the present disclosure greatly reduces the application cost.

[0146] Corresponding to the above-mentioned embodiments, some embodiments of the present disclosure also propose a vehicle charging interface assembly.

[0147] As shown in FIG. 8, the vehicle charging interface assembly 200 of some embodiments of the present disclosure includes a first pin 10, a second pin 20 and a third pin 30.

[0148] The first pin 10 is adapted to connect the power pin 210 of the external power supply. The second pin 20 is adapted to connect the ground pin 220 of the external power supply. The third pin 30 is adapted to connect the gun pin 230 of the external charging pile. In this case, the vehicle charging interface assembly 200 is configured to determine the type of the external charging pile based on at least one of the high-low level signal of the second pin 20 and the resistance signal of the third pin 30 through the vehicle controller 400 in the case that the external power supply is connected and the charging gun is inserted.

[0149] For example, 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 gun pin 230 of the external charging pile corresponds to CC2 in Table 1. The functions of A+ and A- are to provide low-voltage auxiliary power for the vehicle by the national standard charging pile, and A+ and A- will output signals at the same time after the user inserts the gun and brushes the card, that is, the first pin 10 and the second pin 20 are triggered at the same time.

[0150] In the case of the Japanese charging standard, the power supply pin 210 of the external power supply corresponds to Charge sequence signal 1 in Table 1, the ground pin 220 of the external power supply corresponds to Charge sequence signal 2 in Table 1, and the plug pin 230 of the external charging pile corresponds to Connector proximity detection in Table 1. After the user inserts the gun and swipes the card, Charge sequence signal 1 is activated first, and then after interacting with the vehicle, judging the electric lock, and detecting the insulation, the charging pile activates Charge sequence signal 2. The signals output by Charge sequence signal 1 and Charge sequence signal 2 are used to represent the progress of the process, rather than to power the vehicle. After the user inserts the gun and swipes the card, Charge sequence signal 1 and Charge sequence signal 2 output signals in turn, that is, the first pin 10 and the second pin 20 are triggered at different times.

[0151] Therefore, in the national charging standard and the Japanese charging standard, although the first pin A and the second pin B receive high and low level signals, the meanings and triggering times of the received signals in the two standards are different, so the type of the external charging pile currently connected can be determined according to the triggering time of the detection signal of the second pin 20.

[0152] The third pin 30 is used to identify whether a charging gun is connected. For different charging standards, the signals emitted by the connected charging gun have different resistances, so in the case where 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 the external charging pile currently connected.

[0153] In this embodiment, in the case where the external power supply is connected based on the detection signal of the first pin 10 and the 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 signals of the third pin 30, or according to the high and low level signals of the second pin 20 and the resistance signals of the third pin 30, without limitation. Then, the corresponding charging standard is determined according to the determined type of the charging pile, and the charging control is performed according to the corresponding charging standard.

[0154] In some embodiments, the vehicle charging interface assembly 200 is further configured to, by the vehicle controller 400, determine that the external charging pile is the first charging pile if the signal input from the second pin 20 is a low-level signal when the first pin 10 and the third pin 30 are identified to be connected to the external power supply and the charging gun is inserted; determine that the external charging pile is the second charging pile if the signal input from the second pin 20 is not a low-level signal (e.g., the signal is a high-level signal).

[0155] For example, 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. In the case that the first pin 10 has an external power supply input and the third pin 30 has a charging connection signal (i.e., the charging gun is successfully connected), if it is detected that the signal input from the second pin 20 is a low-level signal, the second pin 20 is triggered at the same time as the first pin 30, and the signals received by the first pin 10 and the second pin 20 are used to provide low-voltage auxiliary power to the vehicle, thereby confirming that the currently connected external charging pile is a national standard charging pile; if the signal input from the second pin 20 is not a low-level signal, the first pin 10 and the second pin 20 are triggered at different times, and the signals received by the first pin 10 and the second pin 20 are used to represent the progress of the process, thereby confirming that the currently connected external charging pile is a Japanese standard charging pile.

[0156] In some embodiments, the vehicle charging interface assembly 200 is further configured to, by the vehicle controller 400, determine that the external charging pile is the second charging pile if it is determined according to the gun insertion signal of the third pin 30 that the third pin 30 is connected to the first connection resistor when the first pin 10 and the third pin 30 are identified to be connected to the external power supply and the charging gun is inserted; determine that the external charging pile is the first charging pile if it is determined according to the gun insertion signal of the third pin 30 that the third pin 30 is connected to the second connection resistor. The resistance value of the second connection resistor is different from that of the first connection resistor, which can be set according to actual conditions. For example, the resistance value of the second connection resistor is greater than that of the first connection resistor.

[0157] That is, for different charging standards, the resistance value of the connection resistor connected by the charging gun is different, so that, in the case that the external power supply is connected and the charging gun is inserted, the connection resistor connected by the third pin 30 can be determined based on the gun insertion signal of the third pin 30, and the type of the connected external charging pile can be determined based on different connection resistors. The mapping relationship between the level of the gun insertion signal and the resistance value of the connection resistor can be established in advance to determine the connection resistor connected by the third pin 30.

[0158] In some embodiments, the third pin 30 is further adapted to be connected to the first preset power source through the first pull-up resistor, and the third pin 30 is further adapted to connect one end of the first connection resistor, and the other end of the first connection resistor is connected to the protection ground; or, the third pin 30 is further adapted to be connected to the first preset power source through the first pull-up resistor, and the third pin 30 is further adapted to connect one end of the second connection resistor, and the other end of the second connection resistor is connected to the vehicle body ground.

[0159] For example, when charging the vehicle by using the Japanese standard charging pile, the first connection resistor and the first pull-up resistor divide the voltage of the first preset power source to obtain the corresponding plug-in signal; when charging the vehicle by using the national standard charging pile, the second connection resistor and the first pull-up resistor divide the voltage of the first preset power source to obtain the corresponding plug-in signal. Thus, the type of the connected external charging pile can be determined based on the plug-in signal of the third pin 30.

[0160] In some embodiments, as shown in FIG. 9, the vehicle charging interface assembly 200 further comprises a fourth pin 50. The fourth pin 50 is connected to the vehicle controller 400 through a first resistor R21, and is connected to the vehicle body ground through a second resistor R22, and the first resistor R21 and the second resistor R22 have the same resistance value. The vehicle charging interface assembly 200 is configured to: ground the first resistor R21 by the vehicle controller 400 in the case that the external charging pile is a second charging pile; and leave the first resistor R21 floating in the case that the external charging pile is a first charging pile.

[0161] That is, the vehicle charging interface assembly 200 further comprises the fourth pin 50, the first resistor R21 and the second resistor R22. In combination with Table 1, the fourth pin 50 is the pin D in Table 1.

[0162] Taking the first charging pile as the national standard charging pile and the second charging pile as the Japanese standard charging pile as an example. Initially, the first resistor is set to be in a disconnected floating state. In the case that the external charging pile is determined to be the Japanese standard charging pile, the vehicle controller 400 controls the first resistor R21 to be grounded when the vehicle allows charging, triggering the fourth pin 50 to be effective; in the case that the external charging pile is determined to be the national standard charging pile, the vehicle controller 400 keeps the first resistor R21 in a disconnected floating state, and the fourth pin 50 is ineffective. In this way, different charging standard requirements can be met.

[0163] In some embodiments, the vehicle charging interface assembly 200 further comprises a connector. The first pin 10, the second pin 20, the third pin 30 and the fourth pin 50 are arranged in the connector. In order to better realize the switching between the charging modes compatible with different standards, the connection relationship of the pins is fixed by the connector.

[0164] It should be noted that details not disclosed in the vehicle charging interface assembly 200 of some embodiments of the present disclosure can refer to the details disclosed in the charging control device 100 of the above-mentioned embodiments of the present disclosure, which will not be described here.

[0165] According to the vehicle charging interface assembly 200 of some embodiments of the present disclosure, the first pin is adapted to connect to the power pin of the external power supply, the second pin is adapted to connect to the ground pin of the external power supply, and the third pin is adapted to connect to the gun pin of the external charging pile. In the case that the first pin and the third pin are identified by the vehicle controller that 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 / low level signal of the second pin and the resistance signal of the third pin.
