[0002] With the increasing severity of environmental pollution and the international energy situation, new energy vehicles have attracted more and more attention due to their advantages such as low environmental pollution and high energy efficiency.
[0003] When charging new energy vehicles, the charging gun needs to be inserted into the vehicle's charging port to charge the vehicle's power battery. The charging gun electronic lock (also known as a charging gun electronic lock) is a device used to lock the charging gun to the charging port during the charging process. Its main function is to prevent the charging gun from being accidentally pulled out during charging. Especially under high-current charging conditions, it can prevent the generation of electric arcs caused by pulling out the gun, thereby ensuring equipment safety and operator safety.

[0093] Figure 5 This is a schematic diagram of the structure of a vehicle provided in an embodiment of this application. Detailed Implementation
[0094] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0095] In this application, the terms "first," "second," etc., are used to distinguish identical or similar items that have essentially the same function. It should be understood that there is no logical or temporal dependency between "first," "second," and "nth," nor does it limit the quantity or execution order. It should also be understood that although the following description uses the terms "first," "second," etc., to describe various elements, these elements should not be limited by the terms.
[0096] These terms are simply used to distinguish one element from another. For example, without departing from the various examples, the first element can be referred to as the second element, and similarly, the second element can be referred to as the first element. Both the first and second elements can be elements, and in some cases, they can be separate and distinct elements.
[0097] "At least one" refers to one or more elements. For example, at least one element can be one element, two elements, three elements, or any integer number of elements greater than or equal to one. "Multiple" refers to two or more elements. For example, multiple elements can be two elements, three elements, or any integer number of elements greater than or equal to two.
[0098] In this article, "and / or" indicates that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0099] It should be noted that all information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data used for analysis, stored data, displayed data, etc.), and signals involved in this application have been authorized by the user or fully authorized by all parties, and the collection, use, and processing of related data must comply with the relevant laws, regulations, and standards of the relevant regions. For example, the initial text and interest tags involved in this application were obtained with full authorization.
[0100] The control scheme for the charging electronic lock provided in this application is applicable to new energy vehicles. For example, during the AC slow charging process of a vehicle's power battery, this application embodiment is used to control the charging electronic lock to unlock and lock (also known as lock). Figure 1 This is a schematic diagram of the architecture of a control system for a rechargeable electronic lock provided in an embodiment of this application. Figure 1 As shown, the system includes: a Conversion Distribution Unit (CDU) 11, a Battery Management System (BMS) 12, a Front Left Zone Control Unit (FLZCU) 13, an Integrated Cockpit Controller (ICC) 14, a charging gun (e.g., for AC slow charging) 15, a charging electronic lock 16, and a remote control module 17.
[0101] Among them, CDU11 is used for slow charging control and charging electronic lock control; BMS12 is mainly used for intelligent management and maintenance of each battery cell, monitoring the battery status, preventing overcharging and over-discharging, and extending battery life; FLZCU13 is used to provide power mode control functions and vehicle arming / disarming status management functions; ICC14 is used to display vehicle charging information and control the unlocking of the charging electronic lock. For example, the remote control module 17 is a T-BOX module. The T-BOX module, as a wireless communication module, supports users to remotely view charging-related information and remotely control the unlocking of the charging electronic lock.
[0102] The control scheme for the charging electronic lock will be described in detail below through the following implementation method.
[0103] Figure 2 This is a flowchart illustrating a control method for a charging electronic lock according to an embodiment of this application. The execution subject of this method is the CDU on the vehicle, see [link / reference]. Figure 2 The method includes the following steps:
[0104] 201. The CDU acquires the battery charging status and vehicle status; wherein, the battery charging status is used to indicate whether the vehicle has experienced a charging failure; the vehicle status includes at least the vehicle disarming status and the vehicle thermal runaway status.
[0105] The first point to clarify is that if a vehicle experiences a charging malfunction, the car's battery cannot be charged, and the vehicle is in a state where the battery is not being charged; if the vehicle does not experience a charging malfunction, the car's battery can be charged, and the vehicle is in a state where the battery is being charged.
[0106] The second point to clarify is that the vehicle's arming / disarming status indicates whether the vehicle's anti-theft system is activated. Arming refers to a protected state entered via the remote key or vehicle system settings after all doors and charging port covers are closed. In this state, if a door or charging port cover is illegally opened, the anti-theft system will trigger an alarm to warn and deter potential intruders. Disarming, on the other hand, means disarming the vehicle, which typically involves deactivating the anti-theft system so that the vehicle can be returned to a drivable state.
[0107] The third point to note is that the vehicle thermal runaway status is used to indicate whether a thermal runaway fault has occurred in the vehicle.
[0108] 202. CDU obtains the unlocking method for the charging electronic lock.
[0109] In the embodiments of this application, the unlocking methods of the charging electronic lock include, but are not limited to: manual pull ring unlocking, remote unlocking via mobile APP, and vehicle ICC soft switch unlocking. This application does not limit the methods in this regard.
[0110] The fourth point to note is that after obtaining the above information through steps 201-202, it can be used... Figure 3 The state transition diagram shown is used to control the working state of the charging electronic lock, as detailed in step 203 below.
[0111] 203. In the current working state of the charging electronic lock, the CDU controls the charging electronic lock to switch working states based on at least one of the following: battery charging status, vehicle status, unlocking method of the charging electronic lock, or malfunction of the charging electronic lock.
[0112] For example, the operating states of the rechargeable electronic lock include an unlocked state and a locked state. Further, the unlocked state is subdivided into a first unlocked state and a second unlocked state. The difference between these two unlocked states is that in the first unlocked state, the unlocking time of the rechargeable electronic lock is unlimited. In the second unlocked state, the unlocking time of the rechargeable electronic lock is a preset duration. That is, after the preset duration, the rechargeable electronic lock automatically returns to the locked state. For example, the preset duration is 30 seconds, meaning the lock is unlocked for 30 seconds, and then automatically returns to the locked state after 30 seconds.
[0113] The following is combined Figure 3 The scenarios shown in Scenario 1 to Scenario 5 illustrate how to control the charging electronic lock to switch working states.
[0114] Scenario 1: Switching from the first unlocked state to the locked state.
[0115] In this scenario, if the current working state of the charging electronic lock is the first unlocked state, then if any of the following conditions are met, the charging electronic lock will be controlled to switch from the first unlocked state to the locked state.
[0116] Condition 1: The charging gun is connected to the vehicle's charging interface, the CDU receives the target status information or battery heating request sent by the BMS, and the charging electronic lock is not malfunctioning.
[0117] For example, the charging gun mentioned herein is a charging gun for AC slow charging, and this application is not limited to this. The target state information is used to indicate whether the battery is in a charging state or a pre-charging state.
[0118] For example, if the charging gun for AC slow charging is connected to the vehicle's charging interface, and the CDU receives status information from the BMS indicating that the battery is in a charging state, and the charging electronic lock is fault-free, then the CDU drives the charging electronic lock to lock.
[0119] Condition 2: The vehicle is armed, the charging gun is connected to the vehicle's charging interface, the charging electronic lock is not malfunctioning, and the vehicle has not experienced thermal runaway.
[0120] For example, if the vehicle is armed, the charging gun for AC slow charging is connected to the vehicle's charging interface, the charging electronic lock is functioning properly, and the vehicle has not experienced thermal runaway, then the CDU will drive the charging electronic lock to lock.
[0121] Furthermore, if the charging electronic lock malfunctions in scenario one, it will not enter the locked state. Instead, the charging current must be controlled below a first value. Once the fault is resolved, if the conditions for entering the locked state are met, the charging electronic lock will be driven to lock, and the charging current will be restored. For example, the first value is 16A, but this application does not limit it to this value.
[0122] Scenario 2: Switching from the locked state to the first unlocked state.
[0123] In this scenario, if the current working state of the charging electronic lock is locked, then if any of the following conditions are met, the charging electronic lock will be controlled to switch from the locked state to the first unlocked state.
[0124] Condition 1: The vehicle is currently in an unlocked state, and the CDU has received a charging completion signal from the BMS, and the charging electronic lock is not malfunctioning.
[0125] For example, if the vehicle is in an unlocked state and the charging electronic lock is not malfunctioning, the CDU will drive the charging electronic lock to unlock after receiving a charging completion signal from the BMS.
[0126] Condition 2: The vehicle is currently in an unlocked state, the S3 switch on the charging gun is pressed, and the charging electronic lock is not malfunctioning.
[0127] For example, if the vehicle is in an unlocked state and the charging electronic lock is not malfunctioning, pressing the S3 switch will enter the unlocked state and drive the charging electronic lock to unlock.
[0128] Condition 3: The vehicle is currently in an unlocked state, the battery is currently not charging, and the charging electronic lock is not malfunctioning.
[0129] For example, if the vehicle is in an unlocked state and the battery cannot be charged due to a charging malfunction when the charging electronic lock is not faulty, it will enter an unlocked state and drive the charging electronic lock to unlock.
[0130] Condition 4: The vehicle is currently in an unlocked state, and a charging stop operation has been detected, and the charging electronic lock is not malfunctioning.
[0131] For example, if the vehicle is in an unlocked state and actively stops charging (e.g., power is cut off at the charging station) when the charging electronic lock is not malfunctioning, it will enter the unlocked state and drive the charging electronic lock to unlock.
[0132] Condition 5: Manually pull the ring to unlock.
[0133] If the user manually pulls the ring to unlock the charging electronic lock when the charging electronic lock is not malfunctioning, it will enter the unlock state and drive the charging electronic lock to unlock.
[0134] Condition 6: The vehicle experiences thermal runaway.
[0135] In the event of a thermal runaway fault in the vehicle, if the CDU receives a thermal runaway signal from the BMS, it will enter the unlocking state and drive the charging electronic lock to unlock.
[0136] Furthermore, if the charging electronic lock switches from the locked state to the first unlocked state due to a thermal runaway fault in the vehicle, the charging electronic lock is prohibited from switching to the locked state for a preset number of ignition cycles. For example, the preset number is 1, but this application does not limit this.
[0137] Scenario 3: Switching from the locked state to the second unlocked state.
[0138] In this scenario, if the current working state of the charging electronic lock is locked, then if any of the following conditions are met, the charging electronic lock will be switched from the locked state to the second unlocked state.
[0139] Condition 1: Remote unlocking via application.
[0140] For example, if unlocking is done remotely via a mobile app, the CDU enters a second unlocking state after receiving the remote unlocking signal sent by the T-BOX module, drives the charging electronic lock to unlock, and starts timing.
[0141] Condition 2: Unlock via the virtual switch displayed on the vehicle's screen.
[0142] For example, if unlocked via the vehicle's ICC soft switch (large screen soft switch), the CDU enters the second unlocking state after receiving the unlocking signal sent by the ICC, drives the charging electronic lock to unlock, and starts timing.
[0143] Condition 3: The vehicle switches from armed to disarmed state.
[0144] For example, if the vehicle switches from armed to disarmed, the CDU enters the second unlocking state after receiving the transition edge indicating that the vehicle has switched from armed to disarmed, drives the charging electronic lock to unlock, and starts timing.
[0145] Furthermore, after the charging electronic lock switches from the locked state to the second unlocked state, if the battery is currently charging, the charging current is controlled below a second value. For example, the second value is 16A, but this application does not limit this value. Additionally, if the conditions for entering the locked state are met after the unlocking time exceeds a preset time, the charging electronic lock is driven to lock, and the charging current is restored.
[0146] Scenario 4: Switching from the second unlock state to the first unlock state.
[0147] In this scenario, if the current working state of the charging electronic lock is the second unlock state, then if any of the following conditions are met, the charging electronic lock will be controlled to switch from the second unlock state to the first unlock state.
[0148] Condition 1: No charging connection confirmation signal was detected, and the charging electronic lock is not malfunctioning.
[0149] For example, if no CC signal is detected (e.g., the S3 switch is pressed or the gun is pulled out within 30 seconds of unlocking), the system enters the first unlocking state, driving the charging electronic lock to unlock.
[0150] Condition 2: Charging is completed in the second unlocked state, the charging gun is connected to the vehicle's charging port, and the charging electronic lock is not malfunctioning.
[0151] For example, if charging is completed within 30 seconds of unlocking when the charging gun is connected and the charging electronic lock is not malfunctioning, the CDU will drive the charging electronic lock to unlock after receiving the charging completion signal sent by the BMS.
[0152] Condition 3: The vehicle is in the unlocked state, and a charging failure or a stopped charging operation is detected in the second unlocked state, and the charging electronic lock is not malfunctioning.
[0153] For example, if the vehicle is in an unlocked state and charging fails or stops actively within 30 seconds of unlocking, the CDU will drive the charging electronic lock to unlock.
[0154] Condition 4: Manually pull the ring to unlock.
[0155] Condition 5: The vehicle experiences thermal runaway in the second unlocked state.
[0156] For example, if the vehicle experiences thermal runaway within 30 seconds of unlocking, the CDU will drive the charging electronic lock to unlock after receiving the thermal runaway signal from the BMS.
[0157] In addition, if the charging electronic lock switches from the second unlocked state to the first unlocked state due to a thermal runaway fault in the vehicle, the charging electronic lock is prohibited from switching to the locked state within a preset number of ignition cycles.
[0158] Scenario 5: Switching from the second unlocked state to the locked state.
[0159] In this scenario, if the current working state of the charging electronic lock is the second unlocked state, then if any of the following conditions are met, the charging electronic lock will be controlled to switch from the second unlocked state to the locked state.
[0160] Condition 1: After the unlocking time exceeds the preset duration, the charging gun is connected to the vehicle's charging interface, and the charging electronic lock is not malfunctioning.
[0161] For example, if the charging gun for slow AC charging is connected after the unlocking time exceeds 30 seconds, the vehicle enters the locked state, and the CDU drives the charging electronic lock to lock. In this step, the unlocking method can be unlocking via a mobile app, unlocking via a large-screen soft switch, or switching the vehicle from armed to disarmed state.
[0162] Condition 2: The vehicle switches from the disarmed state to the armed state, and the charging gun is connected to the vehicle's charging interface, and the charging electronic lock is not malfunctioning.
[0163] Additionally, in scenario five, if the battery is in a charging state, the charging current will be restored after the state transition is executed, i.e., after entering the lockout state.
[0164] In summary, this application embodiment achieves intelligent state control of the charging electronic lock during the charging process of new energy vehicles. Specifically, after confirming the current operating state of the charging electronic lock, this application embodiment can intelligently and precisely control the charging electronic lock to switch operating states based on at least one of the following: battery charging state, vehicle state (e.g., vehicle arming / disarming state, vehicle thermal runaway state), unlocking method of the charging electronic lock, or fault condition. This method of controlling the operating state of the charging electronic lock based on diverse data not only improves charging efficiency but also ensures safe charging.
