Description

Technical Field

[0001] This application relates to the technical field of electric vehicles, and particularly to a control method, device and electronic device for a charging and discharging electronic lock. Background Art

[0002] Most charging methods for electric vehicles still use a charging gun to connect the power grid and the vehicle to the charging pile for power supply. At the same time, the discharge of electric vehicles (external discharge) usually uses a discharge gun to connect to an external AC electrical appliance or the vehicle to be charged for external discharge of the vehicle.

[0003] Currently, the vehicle can control the opening and closing of the electronic lock according to the charging state, door lock state, electronic lock state, etc., which can appropriately solve the unlocking and locking requirements of the electronic lock in some scenarios and avoid the situation of the charging cable being stolen.

[0004] However, due to the complex charging and discharging application scenarios, the current control strategy for unlocking and locking the electronic lock is single and cannot fully cover various application scenarios. For example, in the scenario of scheduled charging, the vehicle is locked, but since the scheduled time has not yet arrived and charging has not been started, the charging gun is not locked, and there is a risk of the charging gun cable being stolen; it is impossible to identify a dedicated charging pile, and there may be a situation where the dedicated charging gun is stolen or the charging is interrupted; moreover, the control scenarios of AC discharge and European standard DC charging are not covered. Therefore, it will lead to the problem that the unlocking and locking control strategy of the electronic lock has low adaptability to the scenario, and further lead to the problem of poor user experience.

[0055] The following further elaborates the present application in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are merely for explaining the related invention and not for limiting the invention. Additionally, it should be noted that for the sake of description, only the parts related to the invention are shown in the accompanying drawings.

[0056] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will elaborate on the present application in detail with reference to the accompanying drawings and embodiments.

[0057] Figure 1 It is a flowchart of a control method for a charge-discharge electronic lock provided by an embodiment of the present application. The control method for the charge-discharge electronic lock is applicable to a control device for a charge-discharge electronic lock. The control device for the charge-discharge electronic lock includes an on-vehicle charger, a battery management system, a vehicle controller, a body control module, and an electronic lock. Refer to Figure 1 , the control method for the charge-discharge electronic lock specifically includes:

[0058] S110. The on-board charger obtains the charging gun connection signal and the maximum allowable current passing through the charging pile, determines the connection status and the valid status based on the charging gun connection signal and the maximum allowable current passing through the charging pile, sends the connection status to the battery management system and the vehicle controller, and sends the valid status to the battery management system.

[0059] Among them, the on-board charger (OBC) refers to the charger fixedly installed on the electric vehicle, which has the ability to quickly and conveniently charge the power battery safely. It dynamically adjusts the charging current and voltage parameters according to the data provided by the battery management system (BMS), performs corresponding charging actions, and completes the charging process. The charging gun connection signal can be the CC signal. By detecting the voltage of the CC signal, it is judged whether the AC charger is plugged in and the connection status. It is determined according to the CC value. CC is a constant current, that is, discharging continuously with the same current. CC can be 10A, 16A, 32A or 64A. The subsequent connection status can be determined according to the CC resistance value. Among them, 10A and 16A are for household charging gun products, that is, dedicated charging piles; 32A and 64A are usually for public charging piles. The maximum allowable current passing through the charging pile can be the CP signal. After identifying the CP signal, the maximum allowable current passing through the charging pile can be confirmed. The connection status (CC status) can include connected and not connected, which is used to describe whether the charging gun is successfully connected. The valid status (CP status) can include valid and invalid, which is used to describe whether the power supply capacity of the power supply device is valid. The battery management system is an intelligent management and maintenance battery unit. The vehicle controller (VCU) can control the operation of the electric vehicle motor and can also control the operation of other electronic devices on the electric vehicle.

[0060] Specifically, after inserting the charging gun, the on-board charger can obtain the charging gun connection signal. After the user swipes the card, the on-board charger can obtain the maximum allowable current passing through the charging pile. Furthermore, based on the charging gun connection signal and the maximum allowable current passing through the charging pile, the connection status and the valid status can be judged, and the connection status is sent to the battery management system and the vehicle controller, and the valid status is sent to the battery management system.

[0061] S120. The battery management system determines the charge and discharge mode and the charge and discharge status in the charge and discharge mode based on the connection status and the valid status, and sends the charge and discharge mode and the charge and discharge status to the vehicle controller.

[0062] Among them, the charge and discharge mode includes any one of AC charging, AC discharging, and European standard DC charging; if the charge and discharge mode is AC charging or European standard DC charging, the charge and discharge status includes charging preparation, charging in progress, or charging completed; if the charge and discharge mode is AC discharging, the charge and discharge status includes discharging preparation, discharging in progress, or discharging completed.

[0063] Exemplarily, in the case where the charge and discharge mode is AC charging or European standard DC charging, the charge and discharge status can be understood as the charging status. Among them, charging preparation means the gun has been plugged in but charging has not started yet; charging in progress means the OBC outputs DC power to supply the vehicle; charging completed means the OBC has stopped outputting. In the case where the charge and discharge mode is AC discharging, the charge and discharge status can be understood as the discharging status. Among them, discharging preparation means the gun has been plugged in but discharging has not started yet; discharging in progress means the OBC outputs AC power to supply the external device; discharging ended means the OBC has stopped outputting.

[0064] It can be understood that when the BMS determines that the connection status is connected and the effective status is valid, it can perform a self-check to determine whether the current charging / discharging conditions are met. If the conditions are met, it can send the charge and discharge mode and the charge and discharge status to the VCU, and send a high-voltage request to the VCU, that is, the high-voltage request is a valid request.

[0065] S130. The vehicle controller obtains the electronic lock influence information from the body control module and / or the battery management system according to the connection status, the charge and discharge mode, and the charge and discharge status, and controls the electronic lock to perform an unlocking operation or a locking operation according to the charge and discharge mode, the charge and discharge status, and the electronic lock influence information.

[0066] Among them, the electronic lock influence information is the collected information related to controlling the unlocking and locking of the electronic lock, and is used to judge whether to perform an unlocking operation or a locking operation on the electronic lock subsequently. The electronic lock influence information includes at least one of the charging pile attribute, the charging start and stop instruction, the discharging start and stop instruction, the current status of the central control lock, the change status of the central control lock, the source of the change of the central control lock, and the discharging power. The charging pile attribute includes a dedicated charging pile and a public charging pile. The charging start and stop instruction includes a charging start instruction and a charging stop instruction. The discharging start and stop instruction includes a discharging start instruction and a discharging stop instruction. The current status of the central control lock includes a locked state and an unlocked state. The change status of the central control lock includes changing from the locked state to the unlocked state and changing from the unlocked state to the locked state. The source of the change of the central control lock includes a physical button and a non-physical button (key, NFC, or Bluetooth, etc.). The body control module (BCM) can control the electrical appliances of the vehicle body, such as the vehicle lamps, wipers, washers, door locks, electric windows, sunroofs, electric rearview mirrors, remote control, etc., and also has functions such as power management, high and low voltage protection, delayed power-off, and system sleep.

[0067] Specifically, after receiving the connection status, charge and discharge mode, and charge and discharge status, the VCU can determine the current scenario and determine the information for controlling the electronic lock to perform unlocking and locking operations in the current scenario, that is, the electronic lock impact information. Furthermore, the electronic lock impact information is obtained from the body control module and / or the battery management system, and in the current scenario, based on the obtained electronic lock impact information, it is analyzed to determine whether to perform an unlocking operation or a locking operation on the electronic lock.

[0068] Based on the above example, when the connection status of the vehicle control unit is connected, the charge and discharge mode is AC charging, and the charge and discharge mode is charging preparation, the electronic lock impact information can be obtained and the electronic lock can be controlled to perform unlocking or locking operations through the following methods:

[0069] When the connection status of the vehicle control unit is connected, the charge and discharge mode is AC charging, and the charge and discharge mode is charging preparation, the charging reservation status is determined;

[0070] If the charging reservation status is not reserved, when the vehicle control unit determines that the charge start and stop instruction sent by the battery management system is a charge start instruction, it controls the electronic lock to perform a locking operation;

[0071] If the charging reservation status is reserved, the vehicle control unit obtains the current status of the central locking from the body control module. If the current status of the central locking is the locked state, it controls the electronic lock to perform a locking operation.

[0072] Among them, the charging reservation status includes reserved and not reserved. Reserved means that a fixed time for charging has been reserved, and not reserved means that charging can start immediately after inserting the gun and swiping the card without waiting.

[0073] Specifically, in the scenario where the connection status is connected, the charge and discharge mode is AC charging, and the charge and discharge mode is charging preparation, first, it is judged whether the user has set a reserved charge, that is, the charging reservation status is determined. If the charging reservation status is not reserved, it indicates that charging can be started immediately in the current scenario. Therefore, after the user triggers and issues a charge start instruction based on the battery management system, the electronic lock is controlled to perform a locking operation, and the specific process is as Figure 2 shown. If the charging reservation status is reserved, it indicates that charging is not required at present. When the user leaves the vehicle, the electronic lock can be locked. Therefore, the vehicle control unit obtains the current status of the central locking from the body control module. If it is in the locked state, it indicates that the user has left the vehicle, and the electronic lock should be controlled to perform a locking operation so that the reserved charge operation can be performed after the user leaves. The specific process is as Figure 3 shown.

[0074] Based on the above examples, when the vehicle controller is in the connected state, the charging and discharging mode is the European standard DC charging, and the charging and discharging mode is the charging preparation mode, or when the vehicle controller is in the connected state, the charging and discharging mode is the AC discharge mode, and the charging and discharging mode is the discharge preparation mode, the electronic lock influence information can be obtained in the following ways, and the electronic lock can be controlled to perform an unlocking operation or a locking operation:

[0075] When the vehicle controller is in the connected state, the charging and discharging mode is the European standard DC charging, and the charging and discharging mode is the charging preparation mode, and when it is determined that the charging start and stop command sent by the battery management system is a charging start command, the electronic lock is controlled to perform a locking operation;

[0076] When the vehicle controller is in the connected state, the charge and discharge mode is AC discharge, and the charge and discharge mode is discharge preparation, and when it is determined that the discharge start and stop command sent by the battery management system is a discharge start command, the electronic lock is controlled to perform a locking operation.

[0077] Specifically, when the connection status is connected, the charge and discharge mode is European standard DC charging, and the charge and discharge mode is ready for charging, it indicates that the current scene cannot be reserved and charging is required immediately. Therefore, after the user triggers and initiates the charge start instruction based on the battery management system, the electronic lock is controlled to perform the locking operation. When the connection status is connected, the charge and discharge mode is AC discharge, and the charge and discharge mode is ready for discharge, it indicates that the current scene cannot be reserved and discharging is required immediately. Therefore, after the user triggers and initiates the discharge start instruction based on the battery management system, the electronic lock is controlled to perform the locking operation.

[0078] Based on the above example, when the vehicle controller is in the connected state, the charging and discharging mode is AC charging, and the charging and discharging mode is charging, the electronic lock influence information can be obtained in the following ways, and the electronic lock can be controlled to perform an unlocking operation or a locking operation:

[0079] When the vehicle controller is in the connected state, the charging and discharging mode is AC charging, and the charging and discharging mode is charging, the vehicle controller obtains the central lock change state from the body control module;

[0080] If the central lock changes state from locked to unlocked, the vehicle controller controls the electronic lock to perform the unlocking operation and sends a start current limiting signal to the battery management system;

[0081] If the electronic lock is in the unlocked state for a preset time and the vehicle controller determines that the battery management system has not sent a charging stop command, the vehicle controller controls the electronic lock to perform a locking operation and sends a current limit release signal to the battery management system.

[0082] Among them, the start current limiting signal can be a signal that limits the charging current and the discharging current to a safe range. The release current limiting signal can be a signal that restores the charging current and the discharging current to the current during normal charging and discharging. The preset duration can be the duration used to determine whether to restore the original electronic lock and current conditions during charging, for example, it can be 30s, etc. The specific value can be set according to actual needs.

[0083] Specifically, when the connection status is connected, the charge and discharge mode is AC charging, and the charge and discharge mode is charging, it is possible to preliminarily determine whether the user has the need to unplug the charging gun based on the change in the central lock, that is, the change in the central lock state. If the central lock changes from a locked state to an unlocked state, it indicates that the user opens the central lock and may want to start the vehicle, so there may be a need to unplug the charging gun. Based on this, the electronic lock can be controlled to perform an unlocking operation, and a start current limiting signal can be sent to the battery management system to limit the current charging current and avoid danger when the charging gun is unplugged. However, if the duration of the electronic lock being in the unlocked state reaches a preset duration and the vehicle controller determines that the battery management system has not sent a charging stop instruction, it indicates that the user has no need to stop charging, and may just unlock the central lock to perform some operations that have nothing to do with stopping charging. Therefore, the vehicle controller controls the electronic lock to perform a locking operation, and sends a release current limiting signal to the battery management system to restore the current during normal charging when the electronic lock is locked. The specific process is as follows: Figure 4 shown.

[0084] Based on the above example, when the vehicle controller is in the connected state, the charge and discharge mode is AC discharge, and the charge and discharge mode is discharging, the electronic lock influence information can be obtained in the following ways, and the electronic lock can be controlled to perform an unlocking operation or a locking operation:

[0085] When the vehicle controller is in the connected state, the charge and discharge mode is in AC discharge, and the charge and discharge mode is in discharge, the vehicle controller obtains the central lock change state from the body control module;

[0086] If the central lock changes state from locked state to unlocked state, the vehicle controller obtains the discharge power from the battery management system;

[0087] If the discharge power is greater than the power threshold, the vehicle controller obtains the source of the central lock change from the body control module. If the source of the central lock change is a physical button, the vehicle controller sends a discharge stop command to the battery management system and controls the electronic lock to perform an unlocking operation. If the source of the central lock change is a non-physical button, the vehicle controller controls the electronic lock to remain locked.

[0088] If the discharge power is not greater than the power threshold, the vehicle controller controls the electronic lock to perform an unlocking operation and sends a start current-limiting signal to the battery management system. If the duration of the electronic lock in the unlocked state reaches the preset duration and the vehicle controller determines that the battery management system has not sent a discharge stop command, the vehicle controller controls the electronic lock to perform a locking operation and sends a cancel current-limiting signal to the battery management system.

[0089] Among them, the power threshold can be the discharge power used to determine whether the electronic lock can be unlocked by current limiting under safe conditions.

[0090] Specifically, when the connection state is connected, the charge and discharge mode is AC discharge, and the charge and discharge mode is discharging, it indicates that the change state of the central control lock can be continuously obtained from the body control module, so as to preliminarily judge whether the user has the need to pull out the charging gun according to the change state of the central control lock. If the change state of the central control lock is from the locked state to the unlocked state, it indicates that the user has opened the central control lock and may start the vehicle, so there may be a need to pull out the charging gun. Accordingly, the vehicle controller obtains the discharge power from the battery management system. If the discharge power is greater than the power threshold, it indicates that the charging gun cannot be safely pulled out by current limiting at present. Therefore, the source of the central control lock change can be further judged. When the source of the central control lock change is a physical button, since the physical button is located inside the vehicle, it indicates that the user is inside the vehicle, and it can be determined that the user has the need to pull out the charging gun. Therefore, a discharge stop command can be sent to the battery management system to stop the discharge, ensure safety, and control the electronic lock to perform an unlocking operation. When the source of the central control lock change is not a physical button, it indicates that the user may not be inside the vehicle. At this time, the remote control method is used to control the central control lock. Therefore, the electronic lock can be controlled to remain in the locked state. If the discharge power is not greater than the power threshold, it indicates that the charging gun can be safely pulled out by current limiting. Therefore, the electronic lock can be controlled to perform an unlocking operation, and a start current-limiting signal can be sent to the battery management system to limit the current discharge current and avoid danger when pulling out the charging gun. However, if the duration of the electronic lock in the unlocked state reaches the preset duration and the vehicle controller determines that the battery management system has not sent a discharge stop command, it indicates that the user does not have the need to stop the discharge, and may just unlock the central control lock for some operations, which has nothing to do with stopping the discharge. Therefore, the vehicle controller controls the electronic lock to perform a locking operation and sends a cancel current-limiting signal to the battery management system to restore the current during normal discharge when the electronic lock is locked.

[0091] Based on the above example, when the connection state is connected, the charge and discharge mode is European standard DC charging, and the charge and discharge mode is charging, the vehicle controller can obtain the electronic lock influence information and control the electronic lock to perform an unlocking operation or a locking operation through the following method:

[0092] When the connection status of the vehicle control unit is connected, the charge and discharge mode is European standard DC charging, and the charge and discharge mode is charging, the vehicle control unit obtains the central locking change status from the body control module;

[0093] If the central locking change status is from the locked state to the unlocked state, the vehicle control unit obtains the source of the central locking change from the body control module;

[0094] When the source of the central locking change is a physical button, the vehicle control unit sends a charging stop command to the battery management system and controls the electronic lock to perform an unlocking operation;

[0095] When the source of the central locking change is not a physical button, the vehicle control unit controls the electronic lock to remain in the locked state.

[0096] Specifically, when the connection status is connected, the charge and discharge mode is European standard DC charging, and the charge and discharge mode is charging, it is possible to judge whether the user has the need to unplug the charging gun according to the central locking change status. If the central locking change status is from the locked state to the unlocked state, it indicates that the user has opened the central locking and may start the vehicle, so there may be a need to unplug the charging gun. Based on this, the source of the central locking change can be further determined. When the source of the central locking change is a physical button, since the physical button is located inside the vehicle, it indicates that the user is inside the vehicle, and it can be determined that the user has the need to unplug the charging gun. Therefore, a charging stop command can be sent to the battery management system to stop charging, ensure safety, and control the electronic lock to perform an unlocking operation. When the source of the central locking change is not a physical button, it indicates that the user may not be inside the vehicle. At this time, the central locking is controlled by a remote control method, so the electronic lock can be controlled to remain in the locked state.

[0097] Based on the above example, when the connection status of the vehicle control unit is connected, the charge and discharge mode is AC charging, and the charge and discharge mode is charging completed, the following method can be used to obtain the electronic lock influence information and control the electronic lock to perform an unlocking operation or a locking operation:

[0098] When the connection status of the vehicle control unit is connected, the charge and discharge mode is AC charging, and the charge and discharge mode is charging completed, the vehicle control unit obtains the current central locking status from the body control module;

[0099] If the current central locking status is the unlocked state, the vehicle control unit controls the electronic lock to perform an unlocking operation;

[0100] If the current central locking status is the locked state, the charging pile attributes are obtained from the battery management system. When the charging pile attributes are for a dedicated charging pile, the vehicle control unit controls the electronic lock to remain in the locked state. When the charging pile attributes are for a public charging pile, the vehicle control unit controls the electronic lock to perform an unlocking operation.

[0101] Specifically, when the connection status is connected, the charge and discharge mode is AC charging, and the charge and discharge mode is charging completed, it is possible to first determine whether there is someone in the vehicle according to the current status of the central locking system. If the current status of the central locking system is the unlocked state, it indicates that there is someone in the vehicle, and the vehicle control unit can control the electronic lock to perform an unlocking operation to achieve the effect of automatic unlocking. The specific process is as Figure 5 shown. If the current status of the central locking system is the locked state, the charging pile attribute can be further determined. If the charging pile attribute is a dedicated charging pile, it indicates that if the electronic lock is controlled to perform an unlocking operation, the charging gun may be lost. Therefore, control the electronic lock to remain in the locked state. If an electronic lock unlocking request is triggered subsequently, then perform an unlocking operation on the electronic lock. The specific process is as Figure 6 shown, where it can be determined that the charging pile attribute is a dedicated charging pile according to CC resistance value = 16A. If the charging pile attribute is a public charging pile, it indicates that if the electronic lock is not unlocked for a long time, it will occupy public resources and prevent other vehicles from performing charging operations. Therefore, control the electronic lock to perform an unlocking operation.

[0102] Based on the above example, when the connection status is connected, the charge and discharge mode is AC discharging, and the charge and discharge mode is discharging completed, or when the connection status is connected, the charge and discharge mode is European standard DC charging, and the charge and discharge mode is charging completed, the vehicle control unit can obtain the electronic lock impact information and control the electronic lock to perform an unlocking operation or a locking operation through the following method:

[0103] When the connection status is connected, the charge and discharge mode is AC discharging, and the charge and discharge mode is discharging completed, the vehicle control unit obtains the current status of the central locking system from the body control module. If the current status of the central locking system is the locked state, control the electronic lock to remain in the locked state. If the current status of the central locking system is the unlocked state, control the electronic lock to perform an unlocking operation;

[0104] When the connection status is connected, the charge and discharge mode is European standard DC charging, and the charge and discharge mode is charging completed, the vehicle control unit controls the electronic lock to perform an unlocking operation.

[0105] Specifically, when the connection status is connected, the charge and discharge mode is AC discharging, and the charge and discharge mode is discharging completed, since the charging gun used for discharging is usually a dedicated charging gun, it is possible to judge whether there is someone around according to the current status of the central locking system. If the current status of the central locking system is the locked state, it indicates that there is no one around, avoiding the loss of the charging gun and keeping the electronic lock in the locked state. If the current status of the central locking system is the unlocked state, it indicates that there is someone around, and the electronic lock can be controlled to perform an unlocking operation to achieve the purpose of automatic unlocking for easy removal of the charging gun.
