[0051] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0052] In order to facilitate a clearer understanding of the embodiments of the present application, some relevant technical knowledge is first introduced as follows.

[0053] The national standard for the conductive charging system of electric vehicles requires that when the rated current of the power supply equipment is greater than 16A, the vehicle plug and the power plug must be locked to ensure reliable connection. At present, in order to improve the efficiency of AC charging, the maximum AC charging current of the charger is usually greater than 16A, so the vehicle plug and the power plug need to be locked during AC charging. In addition, the national standard clearly states that for the vehicle interface of DC charging, an electronic lock should be installed on the vehicle plug to prevent the vehicle interface from disconnecting under load.

[0054] At present, the AC charging socket connection methods of domestic OEMs basically adopt the method that the AC charging electronic lock is controlled by the vehicle end, and the DC charging electronic lock is controlled by the charging pile.

[0055] However, considering the advancement of the globalization strategy of electric vehicles and the trend of electric vehicles going overseas, in order to adapt to the charging ports in Europe and other countries (AC and DC charging ports use the same electronic lock) and European standards, it is urgent to develop an electronic lock control strategy that is compatible with domestic and foreign charging needs. At the same time, considering the convenience of user charging operations, it is necessary to optimize the electronic lock control for different charging scenarios to improve the user experience.

[0056] The electronic lock control method, device and vehicle controller provided in the embodiments of the present application are exemplarily introduced below in conjunction with the drawings in the embodiments of the present application.

[0057] Figure 1 This is one of the flow charts of an electronic lock control method provided in an embodiment of the present application, and the method is applied to a vehicle control unit (VCU). Figure 1 As shown, the method includes:

[0058] S101: Obtain a charging mode of a vehicle.

[0059] It should be noted that the vehicle controller VCU, as the central control unit of the electric vehicle, is the core of the entire control system. It is responsible for collecting and processing sensor data from various components of the vehicle, and based on these data and the driver's instructions, comprehensively controls the drive motor, power battery, brake system, steering system and other systems to achieve coordinated operation of the entire vehicle.

[0060] It should be noted that the vehicle charging mode mainly includes DC charging mode and AC charging mode. Among them, the DC charging mode has the characteristics of high charging power and fast charging speed, which is suitable for places that require fast charging; while the AC charging mode has the characteristics of low charging power and slow charging speed, which is suitable for places that require long-term charging.

[0061] In some embodiments, the vehicle controller VCU can communicate with the charging pile, the vehicle's battery management system (BMS), and other components. Through a specific communication protocol, the VCU can receive charging instructions and status information from the charging pile or BMS to determine the current charging mode of the vehicle.

[0062] In some embodiments, the battery control unit (BCU) in the BMS can identify the charging mode of the vehicle through the built-in resistor of the charging gun. Therefore, the VCU can communicate with the BCU to obtain the charging mode of the vehicle.

[0063] S102: When it is determined that the charging mode is a DC charging mode, based on an electronic lock unlocking request signal sent by an electric vehicle communication controller (EVCC), controlling a charging electronic lock built into a charging socket of the vehicle.

[0064] It should be noted that EVCC is a key component in the electric vehicle charging system and a communication hub between electric vehicles and charging piles. It can convert the Controller Area Network (CAN) signal in the national standard charging into the Power Line Communication (PLC) signal in the Combined Charging System (CCS) charging mode, and control the charging process and data exchange. EVCC has the functions of controlling current, voltage, charging mode, pre-charge (Pre-Charge, PNC), vehicle-to-grid (V2G), etc. It can dynamically adjust the output current and voltage of the charging pile according to the charging needs of the electric vehicle and the characteristics of the charging pile to ensure the efficiency and safety of the charging process.

[0065] It should be noted that the vehicle's charging socket has a built-in charging electronic lock. The charging electronic lock is mainly used to ensure that the charging gun can be firmly locked after being inserted into the vehicle's charging socket to prevent others from unauthorized removal of the gun. This can avoid accidental disconnection during charging and ensure the stability and safety of the charging process.

[0066] In an embodiment of the present application, when the charging mode of the vehicle is a DC charging mode, the EVCC can send an electronic lock unlocking request signal to the VCU of the vehicle according to the charging requirements of the vehicle and the characteristics of the charging pile to instruct the VCU to control the charging electronic lock built into the charging socket of the vehicle.

[0067] S103: When it is determined that the charging mode is the AC charging mode, control the charging electronic lock based on target information.

[0068] The target information includes at least one of the following: the connection status between the vehicle and the AC charging gun, the status of the charging electronic lock, the door status of the vehicle, the charging status of the vehicle, and the activation status of the automatic unlocking function of the charging electronic lock.

[0069] It should be noted that the connection status between the vehicle and the AC charging gun includes the fully connected state, the semi-connected state and the disconnected state. Among them, the unconnected state is the state where there is no physical or electrical connection between the vehicle and the AC charging gun; the semi-connected state is the process stage where the physical connection between the vehicle and the AC charging gun begins to form, but has not yet reached the fully connected state; the fully connected state is the state where a stable physical and electrical connection has been established between the vehicle and the AC charging gun.

[0070] It should be noted that the state of the charging electronic lock includes a locked state and an unlocked state (or an unlocked state). The unlocked state means that the charging electronic lock is in an unlocked state, allowing the charging gun to be unplugged from the charging port; the locked state means that the charging electronic lock is in a locked state, preventing the charging gun from being unplugged from the charging port.

[0071] It should be noted that the vehicle door status includes a locked state and an unlocked state. The locked state means that the vehicle door has been locked by a lock (such as a central lock, door lock, etc.) and cannot be opened directly from the outside or inside; the unlocked state means that the vehicle door is not locked and can be opened directly from the outside or inside.

[0072] It should be noted that the charging status of the vehicle includes an uncharged state, a charging state, and a charging completed (or charging ended) state.

[0073] It should be noted that the automatic unlocking function of the vehicle charging electronic lock means that when certain conditions are met (such as charging is completed, the vehicle is started, or the charging appointment time arrives), the charging electronic lock can be automatically unlocked, allowing the driver or operator to unplug the charging gun without manual operation. Users can turn on or off the automatic unlocking function of the charging electronic lock based on their own needs. Among them, the activation state of the automatic unlocking function of the charging electronic lock includes the activated state and the deactivated state.

[0074] In an embodiment of the present application, if it is determined that the charging mode of the vehicle is the AC charging mode, the VCU can control the charging electronic lock based on at least one target information including the connection status between the vehicle and the AC charging gun, the status of the charging electronic lock, the door status of the vehicle, the charging status of the vehicle, and the activation status of the automatic unlocking function of the charging electronic lock, thereby improving the safety and reliability of the charging process and enhancing the user experience and convenience.

[0075] It can be understood that the electronic lock control method provided in the embodiment of the present application controls the charging electronic lock built into the charging socket of the vehicle by utilizing the vehicle controller VCU, wherein when it is determined that the charging mode of the vehicle is the DC charging mode, the charging electronic lock is controlled based on the electronic lock unlocking request signal sent by the electric vehicle communication controller EVCC, and when it is determined that the charging mode is the AC charging mode, the charging electronic lock is controlled based on at least one target information including the connection status between the vehicle and the AC charging gun, the status of the charging electronic lock, the door status of the vehicle, the charging status of the vehicle, and the activation status of the automatic unlocking function of the charging electronic lock. In this way, compatible control of the charging electronic lock in the DC charging mode and the AC charging mode is achieved through the vehicle controller, thereby improving the compatibility of vehicle charging and user experience.

[0076] In some embodiments, the method of controlling the charging electronic lock built into the charging socket of the vehicle based on the electronic lock unlocking request signal sent by the electric vehicle communication controller EVCC includes:

[0077] Based on the electronic lock unlocking request signal, when it is determined that the EVCC requests to lock the charging electronic lock, and when it is determined that the state of the charging electronic lock is unlocked, and the connection state between the vehicle and the DC charging gun is fully connected, a locking instruction is sent to the charging electronic lock to control the charging electronic lock to lock; or,

[0078] Based on the electronic lock unlocking request signal, when it is determined that the EVCC requests to unlock the charging electronic lock, and when it is determined that the state of the charging electronic lock is a locked state, and the connection state between the vehicle and the DC charging gun is a fully connected state, an unlocking instruction is sent to the charging electronic lock to control the charging electronic lock to unlock.

[0079] In the embodiment of the present application, after receiving the electronic lock unlocking request signal sent by the EVCC, the VCU determines whether the EVCC requests to lock or unlock the charging electronic lock based on the request signal; if the EVCC requests to lock the charging electronic lock, the VCU further determines the state of the charging electronic lock and the connection state between the vehicle and the DC charging gun. If the state of the charging electronic lock is unlocked and the connection state between the vehicle and the DC charging gun is fully connected, the VCU sends a locking instruction to the charging electronic lock to control the charging electronic lock to lock; if the EVCC requests to unlock the charging electronic lock, the VCU further determines the state of the charging electronic lock and the connection state between the vehicle and the DC charging gun. If the state of the charging electronic lock is locked and the connection state between the vehicle and the DC charging gun is fully connected, the VCU sends an unlocking instruction to the charging electronic lock to control the unlocking of the charging electronic lock.

[0080] It should be noted that in the European standard DC charging scenario, the BCU can identify the charging mode and the connection status between the vehicle and the DC charging gun through the built-in resistor of the DC charging gun. The VCU can obtain the connection status between the vehicle and the DC charging gun by communicating with the BCU.

[0081] In some embodiments, the VCU may obtain the status of the charging electronic lock by communicating with the vehicle's body domain controller (BDC).

[0082] It should be noted that BDC is an automotive electronic control unit that manages the vehicle's body electronic system and is one of the core components of the vehicle's electrical system. In terms of vehicle safety, BDC communicates with the vehicle's safety control unit to monitor and control the vehicle's safety status and provide safety protection measures such as anti-theft alarms, brake control, etc., including managing the vehicle's electronic lock system.

[0083] In some embodiments, after determining that the European standard certification is successful, the EVCC may send an electronic lock unlocking request signal as a "locking request" to the VCU to request the VCU to control the charging electronic lock to lock.

[0084] In some embodiments, in the DC charging mode, the VCU can control the locking of the charging electronic lock after receiving the electronic lock unlocking request signal sent by the EVCC to represent the DC electronic lock locking request; after charging is completed, the VCU can control the unlocking of the charging electronic lock after receiving the electronic lock unlocking request signal sent by the EVCC to represent the DC electronic lock unlocking request.

[0085] For example, Figure 2 A second flow chart of an electronic lock control method provided in an embodiment of the present application is as follows: Figure 2 As shown, the method includes:

[0086] S201: Obtain a charging mode of a vehicle.

[0087] S202: When it is determined that the charging mode is a DC charging mode, receiving an electronic lock unlocking request signal sent by an electric vehicle communication controller EVCC.

[0088] S203: Based on the electronic lock unlocking request signal, when it is determined that the EVCC requests to lock the charging electronic lock, and when it is determined that the state of the charging electronic lock is unlocked, and the connection state between the vehicle and the DC charging gun is fully connected, a locking instruction is sent to the charging electronic lock to control the charging electronic lock to lock.

[0089] S204: Based on the electronic lock unlocking request signal, when it is determined that the EVCC requests to unlock the charging electronic lock, and when it is determined that the state of the charging electronic lock is a locked state, and the connection state between the vehicle and the DC charging gun is a fully connected state, an unlocking instruction is sent to the charging electronic lock to control the charging electronic lock to unlock.

[0090] It should be noted that, for the description of the same steps and the same contents in this embodiment as those in other embodiments, reference can be made to the description in other embodiments and will not be repeated here.

[0091] It can be understood that the embodiment of the present application effectively realizes the control of the charging electronic lock in the DC charging mode by based on the electronic lock unlocking request signal sent by EVCC, the state of the charging electronic lock and the connection state between the vehicle and the DC charging gun.

[0092] In some embodiments, the electronic lock control method further includes:

[0093] When it is determined that a communication failure occurs in the message containing the electronic lock unlocking request signal sent by the EVCC and the charging state of the vehicle is determined to be a charging completion state, an unlocking instruction is sent to the charging electronic lock to control the charging electronic lock to unlock.

[0094] It should be noted that after receiving the electronic lock unlocking request signal sent by EVCC, VCU will parse it to extract the specific request information for electronic lock unlocking. In addition, VCU will check whether the message containing the received electronic lock unlocking request signal complies with the predetermined communication protocol and format. This includes checking key fields such as the start bit, length, and check bit of the message. If the message format is incorrect or there are obvious errors (such as mismatched check bits), VCU may believe that there is a communication failure in the message. Alternatively, VCU will record the timestamp of the received message and compare it with the expected response time. If no response or confirmation signal is received from EVCC within the set timeout period, VCU may believe that there is a communication failure.

[0095] It should be noted that if a communication failure occurs in the transmission of the electronic lock unlocking request signal, the charging electronic lock should be controlled to be unlocked after the DC charging is completed or ended, so as to avoid the situation where the user is unable to unplug the charging gun due to the failure of the electronic lock unlocking request signal to be sent after the charging is completed, causing trouble to the user's use of the car.

[0096] For example, Figure 3 A third flow chart of an electronic lock control method provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, the method includes:

[0097] S301: Obtain a charging mode of a vehicle.

[0098] S302. When it is determined that the charging mode is a DC charging mode, an electronic lock unlocking request signal sent by an electric vehicle communication controller EVCC is received, and during the receiving process, when it is determined that a communication failure occurs in the message containing the electronic lock unlocking request signal sent by the EVCC, and when it is determined that the charging state of the vehicle is a charging completion state, an unlocking instruction is sent to the charging electronic lock to control the charging electronic lock to unlock.

[0099] It should be noted that, for the description of the same steps and the same contents in this embodiment as those in other embodiments, reference can be made to the description in other embodiments and will not be repeated here.

[0100] It can be understood that the embodiment of the present application can avoid the situation where the user is unable to unplug the charging gun due to the failure of sending the electronic lock unlocking request signal after charging is completed by automatically controlling the unlocking of the charging electronic lock after DC charging is completed or ended.

[0101] In some embodiments, the target information includes the connection status between the vehicle and the AC charging gun, the status of the charging electronic lock, and the door status of the vehicle;

[0102] The controlling the charging electronic lock based on the target information includes:

[0103] Based on the target information, when it is determined that the connection state between the vehicle and the AC charging gun is a fully connected state, the state of the charging electronic lock is an unlocked state, and the door state of the vehicle changes from an unlocked state to a locked state, a locking instruction is sent to the charging electronic lock to control the charging electronic lock to lock.

[0104] It should be noted that in the following charging scenario, if the user sets a scheduled charging, and the charging time has not yet reached the scheduled charging start time, the vehicle has not entered the charging process, and the charging electronic lock will not be actively locked, then other people can unplug the charging gun, making the charging task unable to proceed as the user expects, and may even affect the user's use of the vehicle. In the embodiment of the present application, by additionally considering the door status of the vehicle, when it is determined that the connection status between the vehicle and the AC charging gun is a fully connected state, and the state of the charging electronic lock is an unlocked state, and the door status of the vehicle changes from an unlocked state to a locked state, a locking instruction is sent to the charging electronic lock to control the locking of the charging electronic lock. When the user leaves the vehicle, the charging electronic lock can be locked according to the door status of the vehicle's passenger compartment to prevent others from unplugging the charging gun, making the charging task unable to proceed as the user expects.

[0105] For example, Figure 4 A fourth flow chart of an electronic lock control method provided in an embodiment of the present application is shown in FIG. Figure 4 As shown, the method includes:

[0106] S401: Obtain a charging mode of a vehicle.

[0107] S402: When it is determined that the charging mode is the AC charging mode, obtain target information; the target information includes a connection status between the vehicle and the AC charging gun, a status of the charging electronic lock, and a door status of the vehicle.

[0108] S403. Based on the target information, when it is determined that the connection state between the vehicle and the AC charging gun is a fully connected state, the state of the charging electronic lock is an unlocked state, and the door state of the vehicle changes from an unlocked state to a locked state, a locking instruction is sent to the charging electronic lock to control the charging electronic lock to lock.

[0109] It should be noted that, for the description of the same steps and the same contents in this embodiment as those in other embodiments, reference can be made to the description in other embodiments and will not be repeated here.

[0110] It should be noted that in AC charging mode, if the vehicle needs to be charged at full power, the charging electronic lock needs to be controlled to lock. In some embodiments, after the vehicle enters AC charging, if it is determined that the charging electronic lock is not locked and the connection state between the vehicle and the AC charging gun is fully connected, the VCU can send a locking instruction to the charging electronic lock to control the charging electronic lock to lock.

[0111] In some embodiments, the target information includes the connection status between the vehicle and the AC charging gun, the status of the charging electronic lock, and the door status of the vehicle;

[0112] The controlling the charging electronic lock based on the target information includes:

[0113] Based on the target information, when it is determined that the connection state between the vehicle and the AC charging gun is a fully connected state, the state of the charging electronic lock is a locked state, and the door state of the vehicle changes from a locked state to an unlocked state, an unlocking instruction is sent to the charging electronic lock to control the charging electronic lock to unlock.

[0114] It should be noted that in normal car use scenarios, users may intend to pull out their guns and leave when approaching the vehicle. Therefore, in order to simplify the user's operation process, the embodiment of the present application sets the charging electronic lock to unlock following the door status. If the VCU determines that the door status of the vehicle changes from a locked state to an unlocked state, and determines that the connection status between the vehicle and the AC charging gun is a fully connected state and the state of the charging electronic lock is a locked state, the VCU sends an unlocking command to the charging electronic lock to control the unlocking of the charging electronic lock, so that the user can directly unplug the charging gun and leave.

[0115] For example, Figure 5 A fifth flow chart of an electronic lock control method provided in an embodiment of the present application is as follows: Figure 5 As shown, the method includes:

[0116] S501: Obtain a charging mode of a vehicle.

[0117] S502: When it is determined that the charging mode is the AC charging mode, obtain target information; the target information includes a connection status between the vehicle and the AC charging gun, a status of the charging electronic lock, and a door status of the vehicle.

[0118] S503. Based on the target information, when it is determined that the connection state between the vehicle and the AC charging gun is a fully connected state, the state of the charging electronic lock is a locked state, and the door state of the vehicle changes from a locked state to an unlocked state, an unlocking instruction is sent to the charging electronic lock to control the charging electronic lock to unlock.

[0119] It should be noted that, for the description of the same steps and the same contents in this embodiment as those in other embodiments, reference can be made to the description in other embodiments and will not be repeated here.

[0120] In some embodiments, the target information includes a charging status of the vehicle and a door status of the vehicle;

[0121] The controlling the charging electronic lock based on the target information includes:

[0122] Based on the target information, when it is determined that the charging state of the vehicle is in an AC charging state and the door state of the vehicle changes from a locked state to an unlocked state, determining whether the charging current of the vehicle is less than a set current value;

[0123] When it is determined that the charging current of the vehicle is not less than the set current value, the charging current of the vehicle is controlled to be less than the set current value and then an unlocking instruction is sent to the charging electronic lock to control the charging electronic lock to be unlocked.

[0124] It should be noted that in common car use scenarios, users may intend to unplug the charging gun and leave when approaching the vehicle. If the vehicle is still in AC charging when the user approaches the vehicle, and the door status changes from locked to unlocked, in order to ensure user safety, the charging current can be reduced to below the set current value, and then the charging electronic lock can be controlled to unlock, so that the user can directly unplug the charging gun and leave.

[0125] It should be noted that the set current value in the embodiment of the present application can be 16A required by the national standard, or other current values ​​set based on actual applications that can ensure user safety. The embodiment of the present application does not make specific limitations on this.

[0126] For example, Figure 6 A sixth flow chart of an electronic lock control method provided in an embodiment of the present application is as follows: Figure 6 As shown, the method includes:

[0127] S601: Obtain a charging mode of a vehicle.

[0128] S602: When it is determined that the charging mode is the AC charging mode, obtain target information; the target information includes a charging state of the vehicle and a door state of the vehicle.

[0129] S603: Based on the target information, when it is determined that the charging state of the vehicle is in AC charging state and the door state of the vehicle changes from a locked state to an unlocked state, determine whether the charging current of the vehicle is less than a set current value.

[0130] S604: When it is determined that the charging current of the vehicle is not less than the set current value, control the charging current of the vehicle to be less than the set current value and then send an unlocking instruction to the charging electronic lock to control the charging electronic lock to unlock.

[0131] It should be noted that, for the description of the same steps and the same contents in this embodiment as those in other embodiments, reference can be made to the description in other embodiments and will not be repeated here.

[0132] It can be understood that the embodiment of the present application predicts the user's intention in advance through the door status, and when the vehicle is AC charged, the charging current is first controlled to below the set current value, and then the charging electronic lock is controlled to be unlocked, which can ensure user safety.

[0133] In some embodiments, after the charging current of the vehicle is controlled to be less than the set current value and an unlocking instruction is sent to the charging electronic lock to control the unlocking of the charging electronic lock, the method further includes:

[0134] After determining the set unlocking time of the charging electronic lock, when determining that the connection state between the vehicle and the AC charging gun is a fully connected state, and the charging state of the vehicle is an AC charging state, sending a locking instruction to the charging electronic lock to control the charging electronic lock to lock;

[0135] After determining that the charging electronic lock is locked, the charging current of the vehicle is controlled to enable the vehicle to enter a full-power charging state.

[0136] It should be noted that if the user has no intention of drawing the gun after unlocking the charging electronic lock, the vehicle is still charging at this time. Since the charging current has been limited below the set current value, the charging time of the vehicle is prolonged. Therefore, after unlocking the electronic lock for a set time, the charging electronic lock can be re-locked and the charging current can be controlled to restore the vehicle to full power charging, thereby improving charging efficiency.

[0137] It should be noted that the set duration in the embodiment of the present application can be adaptively set based on actual applications, and the embodiment of the present application does not specifically limit this, for example, the set duration is 2 minutes or 5 minutes.

[0138] In some embodiments, if the user has no intention to draw the gun after unlocking the charging electronic lock, and the vehicle is not being charged at this time, the charging electronic lock may not be re-locked.

[0139] For example, Figure 7 The seventh flow chart of an electronic lock control method provided in the embodiment of the present application is as follows: Figure 7 As shown, the method includes:

[0140] S701: Obtain a charging mode of a vehicle.

[0141] S702: When it is determined that the charging mode is the AC charging mode, obtain target information; the target information includes a charging state of the vehicle and a door state of the vehicle.

[0142] S703: Based on the target information, when it is determined that the charging state of the vehicle is in AC charging state and the door state of the vehicle changes from a locked state to an unlocked state, determine whether the charging current of the vehicle is less than a set current value.

[0143] S704: When it is determined that the charging current of the vehicle is not less than the set current value, control the charging current of the vehicle to be less than the set current value and then send an unlocking instruction to the charging electronic lock to control the charging electronic lock to unlock.

[0144] S705: After determining the set unlocking time of the charging electronic lock, when it is determined that the connection state between the vehicle and the AC charging gun is a fully connected state, and the charging state of the vehicle is an AC charging state, sending a locking instruction to the charging electronic lock to control the charging electronic lock to lock.

[0145] S706: After determining that the charging electronic lock is locked, control the charging current of the vehicle so that the vehicle enters a full-power charging state.

[0146] It should be noted that, for the description of the same steps and the same contents in this embodiment as those in other embodiments, reference can be made to the description in other embodiments and will not be repeated here.

[0147] It can be understood that the embodiment of the present application controls the charging electronic lock to follow the door status unlocking for a set period of time. If it is determined based on the connection status between the vehicle and the AC charging gun that the user has no intention of pulling out the gun, and the vehicle is still in AC charging, then the charging electronic lock is controlled again to lock, and the charging current of the vehicle is controlled so that the vehicle enters a full-power charging state, which can improve the charging efficiency of the vehicle and reduce the charging time of the vehicle.

[0148] In some embodiments, the target information includes the state of the charging electronic lock, the charging state of the vehicle, and the activation state of the automatic unlocking function of the charging electronic lock;

[0149] The controlling the charging electronic lock based on the target information includes:

[0150] Based on the target information, when it is determined that the state of the charging electronic lock is a locked state, the charging state of the vehicle is a charging completion state, and the activation state of the automatic unlocking function of the charging electronic lock is activated, an unlocking instruction is sent to the charging electronic lock to control the unlocking of the charging electronic lock.

[0151] It should be noted that for the scenarios of public AC charging and private AC charging, it is hoped that the charging electronic lock can be automatically unlocked after the commercial operation pile (public pile) is charged, so that other users can use the charging pile conveniently; while for charging with home charging piles (private piles), some brands of charging piles are equipped with identity authentication functions. When the vehicle approaches, the charging pile is controlled to transmit electricity after the identity is identified through Bluetooth. When charging is completed, it is not desired to unlock the electronic lock to prevent others from stealing. Therefore, according to the needs of different scenarios, users can use the vehicle's central control soft switch to set whether to turn on the function of automatically unlocking the electronic lock after the vehicle is charged. After the user turns on the function of automatically unlocking the electronic lock after charging is completed, the charging electronic lock is controlled to unlock when the vehicle charging task is completed (for example, the vehicle charging reaches the cut-off state of charge (State of Charge, SOC) or the scheduled charging end time arrives) or the user actively ends charging.

[0152] In an embodiment of the present application, when the VCU determines that the state of the charging electronic lock is locked, the charging state of the vehicle is charging completion, and the automatic unlocking function of the charging electronic lock is turned on, the VCU can send an unlocking instruction to the charging electronic lock to control the unlocking of the charging electronic lock to facilitate other users to use the charging pile.

[0153] For example, Figure 8 The eighth flow chart of an electronic lock control method provided in the embodiment of the present application is as follows: Figure 8 As shown, the method includes:

[0154] S801. Obtain a charging mode of a vehicle.

[0155] S802. When it is determined that the charging mode is the AC charging mode, obtain target information; the target information includes the state of the charging electronic lock, the charging state of the vehicle, and the activation state of the automatic unlocking function of the charging electronic lock.

[0156] S803. Based on the target information, when it is determined that the state of the charging electronic lock is a locked state, the charging state of the vehicle is a charging completion state, and the activation state of the automatic unlocking function of the charging electronic lock is activated, an unlocking instruction is sent to the charging electronic lock to control the charging electronic lock to unlock.

[0157] It should be noted that, for the description of the same steps and the same contents in this embodiment as those in other embodiments, reference can be made to the description in other embodiments and will not be repeated here.

[0158] It should be noted that the vehicle system mainly involves the vehicle controller VCU, the electric vehicle communication controller EVCC, the body controller BDC, the battery control unit BCU, the on-board charger (OBC), the charging socket and the charging gun. Among them, the VCU can be used as the execution subject to execute the electronic lock control method provided in the embodiment of the present application; the EVCC can send an electronic lock unlocking request signal to the VCU according to the DC charging process; the BDC can collect the state of the charging electronic lock, execute the electronic lock drive and feedback the door state of the vehicle passenger compartment; the BCU can identify the charging gun, determine the connection state between the vehicle and the charging gun, and feedback the battery charging state; the OBC can identify the AC charging pile capacity and cooperate with the electronic lock control strategy to adjust the charging current; the charging socket has a built-in charging electronic lock, and the charging gun has a built-in charging identification resistor that can be used to distinguish between the AC charging mode and the DC charging mode.

[0159] It should be noted that the charging electronic lock control is divided into electronic lock control in AC charging scenarios and electronic lock control in DC charging scenarios. In DC charging, the electronic lock needs to be locked before the charging pile end supplies power, and the electronic lock is unlocked after the pile end stops supplying power, so as to ensure that the user operates the charging within the safe voltage range; in AC charging, the electronic lock control can be locked according to the charging requirements. In addition, the embodiment of the present application can also realize linkage response according to the door status. At the same time, the user can turn on or off the function of automatically unlocking the electronic lock after charging is completed according to the scene requirements.

[0160] In some embodiments, the VCU can control the electronic lock to lock during AC charging to meet the national standard requirement that "when the rated current of the power supply equipment is greater than 16A, the vehicle plug and the power plug must be locked to ensure reliable connection". After charging is completed, the user can choose to automatically unlock the electronic lock: the electronic lock can be automatically unlocked after the public pile AC charging is completed to avoid occupying the charging pile resources; the electronic lock can be unlocked after the private pile AC charging is completed to prevent others from stealing and causing unnecessary economic losses to the user.

[0161] For example, Fig. 9 A ninth flow chart of an electronic lock control method provided in an embodiment of the present application is as follows: Fig. 9As shown, after the user inserts the charging gun into the charging socket of the vehicle to start charging, it can be determined whether the AC charging gun is connected to the vehicle; if it is determined that the AC charging gun is connected to the vehicle, it can be further determined whether the vehicle is charging or whether the entire vehicle is locked; if the vehicle is charging or the entire vehicle is locked and the charging electronic lock is not locked, the charging electronic lock is controlled to be locked; if it is determined that the vehicle charging is completed after the charging electronic lock is locked, it is further determined whether the automatic unlocking electronic lock function switch of the vehicle is turned on; if it is turned on, the charging electronic lock is controlled to be unlocked; if it is determined that the passenger compartment door of the vehicle is unlocked after the charging electronic lock is locked, it is further determined whether the charging current of the vehicle is less than 16A; if it is not less than 16A, the charging current is controlled to be below 16A before the charging electronic lock is controlled to be unlocked; if the vehicle is still charging two minutes after the charging electronic lock is controlled to be unlocked, the charging electronic lock is controlled to be locked again. In addition, after the user inserts the charging gun into the charging socket of the vehicle to start charging, if a locking request sent by the EVCC is received, the charging electronic lock is controlled to be locked; after the charging electronic lock is successfully locked, the vehicle charging process begins, and then after receiving an unlocking request sent by the EVCC, the charging electronic lock is controlled to be unlocked.

[0162] It is understandable that the electronic lock control method provided in the embodiment of the present application is not only adaptable to domestic vehicle-side electronic lock control and AC / DC charging electronic lock control of European standard charging, but also realizes a vehicle charging electronic lock ecological control strategy that combines vehicle body characteristics and user intentions. The electronic lock control method provided in the embodiment of the present application can bring at least the following beneficial effects:

[0163] (1) An electronic lock control strategy compatible with AC charging mode and DC charging mode is implemented, which can support charging of domestic and foreign vehicles; (2) In AC charging mode, by associating the electronic lock control with the door status of the vehicle passenger compartment, no matter how the user controls the door unlocking (such as: Bluetooth key, radio frequency key and mobile phone APP, etc.), the electronic lock will follow the door unlocking state and is not restricted by the unlocking methods of different models; (3) In AC charging mode, when the user sets an appointment to charge during the off-peak period of the power grid, the charging electronic lock can be controlled to prevent malicious pulling of the gun by others; (4) In AC charging mode, the user relies on When approaching a vehicle, the charging electronic lock is controlled to automatically unlock along with the door of the vehicle's passenger compartment, allowing the user to directly unplug the gun to end charging, reducing the number of user operation steps and improving the user experience; (5) In AC charging mode, if the user has not ended charging after the charging electronic lock has been unlocked for a certain period of time, the charging electronic lock is re-locked to restore full-power charging of the vehicle, thereby improving the charging efficiency of the vehicle; (6) In AC charging mode, the user can flexibly set whether to automatically unlock the charging electronic lock. If the public charging pile turns on the automatic unlocking of the electronic lock after charging is completed, it can avoid wasting charging resources. If the private charging pile turns off the automatic unlocking of the electronic lock after charging is completed, it can prevent others from stealing charging.
