[0036] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0037] Before introducing the specific implementation of the present disclosure in detail, first, the application scenario of the present disclosure is described. The present disclosure is applied to a charging device, which may be an IC-CPD (In-cable Control And Protection Device) or a charging pile, as in GB / T18487.1-2015. Figure 1 In the connection mode A shown, the charging device can also be a part of the vehicle, and the charging device is used to connect the power supply socket and the charger, such as Figure 1 As shown, Figure 1 The present invention is a schematic diagram of a charging device according to an exemplary embodiment of the present invention. The charging device may be a function box 1, a vehicle plug 2 and a power supply plug 3. The vehicle plug 2 may be used to connect a charger, and the power supply plug 3 may be used to connect a power supply end socket. The neutral point of the IT power grid system is not directly connected to the ground, but is isolated from the ground by an insulating resistor (e.g., an insulating transformer). The neutral point of the TN power grid is connected to the ground. In the case of abnormal grounding of the power supply end socket of the TN power grid system, there is a risk of leakage when charging the vehicle with alternating current. Since the charging device cannot detect the grounding state of the power supply end socket of the IT power grid system, it regards the grounding state of the power supply end socket of the IT power grid system as abnormal grounding. Therefore, when charging the vehicle in an area where the IT power grid system and the TN power grid system coexist, the charging device directly charges the vehicle when detecting an abnormality in the power supply end socket, and does not distinguish the power grid system charging the vehicle, resulting in a risk of leakage during the charging process of the vehicle, which is not conducive to improving the safety of vehicle charging.

[0038] In order to solve the above technical problems, the present disclosure provides a charging method, device, storage medium, program product and vehicle. The charging method is applied to a charging device, which is used to connect a power supply socket and a charger, and may include: obtaining the grounding state of the power supply socket; when it is determined that the grounding state is abnormal, obtaining ungrounded charging authority data from the charger, and the ungrounded charging authority data is used to characterize whether the vehicle is allowed to be charged when the power supply socket is abnormally grounded; according to the ungrounded charging authority data, the charger is controlled to charge the vehicle. In this way, when it is determined that the grounding state is abnormal, the ungrounded charging authority data can be effectively obtained from the charger, and the ungrounded charging authority data can be used to flexibly control whether the charger charges the vehicle in different power grid coverage areas, so as to avoid charging the vehicle in a power grid coverage area where charging is not allowed, eliminate hidden dangers in the vehicle charging process, and thus improve the safety performance of vehicle charging.

[0039] Figure 2 is a flow chart of a charging method according to an exemplary embodiment of the present disclosure. Figure 2 As shown, the charging method may include the following steps:

[0040] In step 201, the grounding state of the power supply socket is obtained.

[0041] Among them, the grounding status can be used to characterize whether the power supply end socket is grounded. The grounding status can include normal grounding and abnormal grounding. Normal grounding can mean that the power supply end socket is grounded and there is no grounding fault. Abnormal grounding can be other grounding states except normal grounding of the power supply end socket, for example, the power supply end socket is not grounded or the power supply end socket is poorly grounded.

[0042] It should be noted that, when the charging device determines that it is connected to the power supply socket and the charger, the charging device can detect whether the power supply socket is grounded. For example, the charging device can determine whether the power supply socket is grounded by detecting the voltage between the live wire and the ground wire in the power supply socket.

[0043] In step 202, when it is determined that the grounding state is abnormal grounding, ungrounded charging authority data is obtained from the charger.

[0044] The ungrounded charging permission data is used to indicate whether charging of the vehicle is allowed when the grounding of the power supply socket is abnormal.

[0045] In this step, a possible implementation may include: when it is determined that the grounding state is abnormal, sending an authorization query request to the charger, so that the charger sends the ungrounded charging authority data to the charging device in response to receiving the authorization query request.

[0046] It should be noted that the authorization query request may be a PWM signal including a low level corresponding to the first preset current and a high level corresponding to the second preset current, and the difference between the first preset current and the second preset current may be greater than 2% of the first preset current. For example, the first preset current may be 8A, the second preset current may be 9.6A, 10A, 11.2A or 12A, etc., the first preset current may be 10A, the second preset current may be 10.5A, 11A or 12A, etc., the first preset current may be 12A, the second preset current may be 12.3A, 12.5A or 12.6A, etc. In the case where the charging device is an IC-CPD, a grounding indicator light is set on the function box. If it is determined that the grounding state is abnormal, the charging device controls the grounding indicator light to light up, prompting the vehicle user that the power supply end socket is not grounded. When it is determined that the grounding state is abnormal, the charging device can send multiple authorization query requests to the charger, and after sending the authorization query request, continue to send the high level in the authorization query request to the charger. When it is determined that the grounding charging authority data is authorized ungrounded charging, stop sending the high level in the authorization query request. The number of times the charging device sends the authorization query request can be adjusted according to the recognition accuracy of the charger, for example, 3 times, 5 times or 6 times. Before sending the authorization query request to the charger, the charging device can also detect the following: Figure 1 The standby voltage of the detection point 1 is shown in FIG. 1 . When it is determined that the standby voltage is within a preset voltage range (for example, the preset voltage range may be 8V-10V), it is determined that the charging device is connected to the charger.

[0047] In this step, another possible implementation method is to control the charger to charge the vehicle when it is determined that the grounding state is normal.

[0048] In step 203, the charger is controlled to charge the vehicle according to the ungrounded charging authority data.

[0049] It should be noted that the charging device can send a preset level signal to the charger (for example, the preset level range can be the level corresponding to 5V-7V), and when the on-board charger receives the preset level signal, it controls the S2 switch to close so that the charging device can charge the vehicle.

[0050] The above technical scheme can effectively obtain the ungrounded charging authority data from the charger when the grounding state is determined to be abnormal. Through the ungrounded charging authority data, it can flexibly control whether the charger charges the vehicle in different grid coverage areas, avoid charging the vehicle in grid coverage areas where charging is not allowed, eliminate hidden dangers in the vehicle charging process, and thus improve the safety performance of vehicle charging.

[0051] In this step, a possible implementation method can be as follows Figure 3 As shown, Figure 3 According to this disclosure Figure 2 The embodiment shown is a flowchart of a charging method, comprising the following steps:

[0052] In step 2031, when it is determined that the ungrounded charging authority data indicates that ungrounded charging is prohibited, a second preset prompt message is output.

[0053] The ungrounded charging authority data includes authorized ungrounded charging and prohibited ungrounded charging. The second preset prompt information is used to guide the user to input updated ungrounded charging authority data.

[0054] It should be noted that the charging device can output a second preset prompt message to the vehicle when it determines that the ungrounded charging authority data is to prohibit ungrounded charging. When the vehicle receives the second preset prompt message, it displays the second preset prompt message to the vehicle user through a display device (for example: an on-board terminal, an on-board display or an on-board instrument, etc.). For example, the second preset prompt message can be "Charging is completed, please disconnect the charging gun. If you need to continue charging, please enable the vehicle's ungrounded charging authority" or "The power supply socket is not grounded, do you want to enable the vehicle's ungrounded charging authority?"

[0055] In step 2032, the updated ungrounded charging authority data is obtained through a preset interface.

[0056] For example, a pop-up window may be displayed on a display device, the window displays "The power supply end socket is not grounded, do you want to enable the vehicle's ungrounded charging authority?", and a "confirm" button and a "cancel" button are displayed in the window, and the updated ungrounded charging authority data is obtained according to the button selected by the vehicle user. The vehicle user may also be prompted with a second preset prompt message to indicate the location of the vehicle's ungrounded charging authority "enable" button, and the updated ungrounded charging authority data is obtained by turning the "enable" button on or off.

[0057] In step 2033, the charger is controlled to charge the vehicle according to the updated ungrounded charging authority data.

[0058] If the updated ungrounded charging authority data is determined to authorize ungrounded charging, the charger is controlled to charge the vehicle. If the updated ungrounded charging authority data is determined to prohibit ungrounded charging, the charger is controlled to stop charging the vehicle.

[0059] It should be noted that the charging device can send a preset level signal to the charger, and when the on-board charger receives the preset level signal, the control Figure 1The switch S2 shown is closed to enable the charging device to charge the vehicle. Other preset level signals other than the preset level signal can also be sent to the charger. When the on-board charger receives the other preset level signal, the control is as follows Figure 1 The S2 switch is shown open to allow the charging device to charge the vehicle.

[0060] For example, if it is determined that the vehicle user clicks the "Confirm" button in the window within the preset time period, it is determined that the updated ungrounded charging authority data is authorized ungrounded charging, and the charging device controls the charger to charge the vehicle. If it is determined that the vehicle user clicks the "Cancel" button in the window within the preset time period, or the vehicle user does not click the "Confirm" button, it is determined that the updated ungrounded charging authority data is prohibited ungrounded charging, and the charging device controls the charger to stop charging the vehicle. If it is determined that the vehicle user turns on the "Start" button within the preset time period, it is determined that the updated ungrounded charging authority data is authorized ungrounded charging, and the charging device controls the charger to charge the vehicle. If it is determined that the vehicle user does not turn on the "Start" button within the preset time period, it is determined that the updated ungrounded charging authority data is prohibited ungrounded charging, and the charging device controls the charger to stop charging the vehicle.

[0061] In this step, another possible implementation may include: when it is determined that the ungrounded charging authority data is for authorizing ungrounded charging, displaying first preset prompt information, and controlling the charger to charge the vehicle.

[0062] The first preset prompt information is used to indicate that the vehicle is currently in an ungrounded charging state. For example, the first preset prompt information may be "the power supply socket is poorly grounded. Avoid contact with the vehicle body during charging."

[0063] Optionally, the charging method may further include the following steps:

[0064] When it is determined that the ungrounded charging authority data is not received within a specified time period, the charger is controlled to charge the vehicle.

[0065] The pointing time period may be 2s, 3s or 5s.

[0066] It should be noted that the failure to receive the ungrounded charging authority data within the specified time period may include the absence of the ungrounded charging authority data in the vehicle, or a communication failure between the charging device and the charger. When the charging device determines that the grounding state is abnormal, it sends an authorization query request to the charger. When the charger receives the authorization query request, it searches for the ungrounded charging authority data. When the ungrounded charging authority data is not found, the charger may not send the ungrounded charging authority data to the charging device. When the charging device determines that the ungrounded charging authority data is not received within the specified time period, it controls the charger to charge the vehicle.

[0067] The technical solution of steps 2031 to 2033 can guide the vehicle user to update the ungrounded charging authority data through the second preset prompt information when it is determined that the ungrounded charging authority data is forbidding ungrounded charging, and flexibly and effectively control the charger to charge the vehicle according to the updated ungrounded charging authority data, thereby expanding the application scope of the charging equipment.

[0068] Figure 4 is a flow chart of another charging method according to an exemplary embodiment of the present disclosure, such as Figure 4 As shown, before controlling the charger to charge the vehicle, the charging method may further include the following steps:

[0069] In step 204, a target charging request is sent to the charger, where the target charging request includes a charging start instruction and a charging parameter, so that the charger charges the vehicle according to the charging start instruction and the charging parameter.

[0070] The charging parameter may be a charging current, a charging voltage or a charging power.

[0071] It should be noted that, when receiving the charge start instruction, the charger can use the minimum value of the charging current sent by the charging device, the preset charging current of the charger and the preset current corresponding to the resistance in the vehicle plug as the current for charging the vehicle.

[0072] The above technical solution can send a charging start instruction and charging parameters to the charger so that the charger can effectively charge the vehicle through the charging start instruction and the charging parameters. The parameters for charging the vehicle in time can avoid damage to the vehicle caused by excessive charging current, thereby improving the safety of vehicle charging.

[0073] Figure 5 is a flow chart of another charging method according to an exemplary embodiment of the present disclosure, such as Figure 5 As shown, before controlling the charger to charge the vehicle, the charging method may further include the following steps:

[0074] In step 501, the grounding state of the power supply socket is obtained.

[0075] Among them, the grounding status can be used to characterize whether the power supply socket is grounded. The grounding status can include normal grounding and abnormal grounding. Normal grounding can mean that the power supply socket is grounded and there is no grounding fault. Abnormal grounding can mean that the power supply socket is not grounded or the power supply socket is poorly grounded.

[0076] In step 502, it is determined whether the grounding state is a grounding abnormality.

[0077] It should be noted that, when it is determined that the grounding state is abnormal, step 503 is executed; when it is determined that the grounding state is normal, step 510 is executed.

[0078] In step 503, an authorization query request is sent to the charger, so that the charger sends the ungrounded charging authority data to the charging device in response to receiving the authorization query request.

[0079] The ungrounded charging permission data is used to characterize whether the vehicle is allowed to be charged when the grounding of the power supply socket is abnormal. The ungrounded charging permission data includes authorization of ungrounded charging and prohibition of ungrounded charging. The authorization query request can be a PWM signal including a low level corresponding to a first preset current and a high level corresponding to a second preset current, and the difference between the first preset current and the second preset current can be greater than 2% of the first preset current.

[0080] In step 504, it is determined whether the groundless charging authority data is received within a specified time period.

[0081] Among them, the pointing time period can be 2s, 3s or 5s, etc.

[0082] It should be noted that, if it is determined that the ungrounded charging authority data is received within the specified time period, step 505 is executed; if it is determined that the ungrounded charging authority data is not received within the specified time period, step 510 is executed.

[0083] In step 505 , it is determined whether the ungrounded charging authority data indicates that ungrounded charging is prohibited.

[0084] It should be noted that, when it is determined that the ungrounded charging authority data is forbidding ungrounded charging, step 506 is executed; when it is determined that the ungrounded charging authority data is for authorizing ungrounded charging, step 509 is executed.

[0085] In step 506, a second preset prompt message is output.

[0086] The second preset prompt information is used to guide the user to enter the updated ungrounded charging permission data. For example, the second preset prompt information can be "Charging is finished, please disconnect the charging gun. If you need to continue charging, please enable the vehicle's ungrounded charging permission" or "The power supply socket is not grounded, do you want to enable the vehicle's ungrounded charging permission?"

[0087] In step 507, the updated ungrounded charging authority data is obtained through a preset interface.

[0088] In step 508 , it is determined whether the updated groundless charging authority data authorizes groundless charging.

[0089] It should be noted that, when it is determined that the updated ungrounded charging authority data is for authorizing ungrounded charging, step 510 is executed; when it is determined that the updated ungrounded charging authority data is for prohibiting ungrounded charging, step 512 is executed.

[0090] In step 509, a first preset prompt message is displayed.

[0091] The first preset prompt information is used to indicate that the vehicle is currently in an ungrounded charging state. For example, the first preset prompt information may be "the power supply socket is poorly grounded. Avoid contact with the vehicle body during charging."

[0092] In step 510, a target charging request is sent to the charger, where the target charging request includes a charging start instruction and a charging parameter, so that the charger charges the vehicle according to the charging start instruction and the charging parameter.

[0093] The charging parameter may be a charging current, a charging voltage or a charging power.

[0094] It should be noted that, when receiving the charge start instruction, the charger can use the minimum value of the charging current sent by the charging device, the preset charging current of the charger and the preset current corresponding to the resistance in the vehicle plug as the current for charging the vehicle.

[0095] In step 511, the charger is controlled to charge the vehicle.

[0096] It should be noted that the charging device can send a preset level signal to the charger, and when the on-board charger receives the preset level signal, the control Figure 1 The S2 switch is shown closed to allow the charging device to charge the vehicle.

[0097] In step 512, the charger is controlled to stop charging the vehicle.

[0098] It should be noted that the charging device can send other preset level signals other than the preset level signal to the charger. When the on-board charger receives the other preset level signal, the control is as follows: Figure 1 The S2 switch is shown open to allow the charging device to charge the vehicle.

[0099] The above technical scheme can effectively obtain the ungrounded charging authority data from the charger when the grounding state is determined to be abnormal. Through the ungrounded charging authority data, it can flexibly control whether the charger charges the vehicle in different grid coverage areas, avoid charging the vehicle in grid coverage areas where charging is not allowed, eliminate hidden dangers in the vehicle charging process, and thus improve the safety performance of vehicle charging.
