Description

Technical Field

[0001] The present application relates to the field of new energy vehicles, and in particular to a control method and device for a charging electronic lock. Background Art

[0002] As environmental pollution problems and the international energy situation become increasingly severe, new energy vehicles have attracted more and more attention due to their advantages such as low environmental pollution and high energy utilization rate.

[0003] Among them, when charging new energy vehicles, it is necessary to insert the charging gun into the charging port on the vehicle to charge the vehicle's power battery. The charging gun electronic lock (also known as the charging gun electronic lock) is a device used to lock the charging gun and the charging port during the charging process. Its main function is to prevent the charging gun from being accidentally unplugged during the charging process. Especially in the case of high current charging, it can avoid the arc caused by pulling out the gun, thereby ensuring the safety of the equipment and the operator.

[0004] Based on the above description, it can be seen that the charging electronic lock plays a vital role in the charging process. Therefore, it is particularly important to perform intelligent state control on the charging electronic lock, because this can not only improve the charging efficiency but also achieve safe charging.

[0094] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0095] In this application, the terms "first", "second", etc. are used to distinguish the same or similar items with substantially the same role and function. It should be understood that there is no logical or temporal dependency between "first", "second", and "nth", nor is there a limitation on the quantity and 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 only used to distinguish one element from another element. For example, without departing from the scope of various examples, a first element can be referred to as a second element, and similarly, a second element can also be referred to as a first element. Both the first element and the second element can be elements, and in some cases, can be separate and different elements.

[0097] Here, at least one means one or more than one, for example, at least one element can be one element, two elements, three elements, or any other integer greater than or equal to one. And multiple means two or more than two, for example, multiple elements can be two elements, three elements, or any other integer greater than or equal to two.

[0098] The "and / or" mentioned in this article indicates that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects before and after are in an "or" relationship.

[0099] It should be noted that the 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 are all authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant 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 are obtained with full authorization.

[0100] The control scheme of the charging electronic lock provided in the embodiment of the present application is applicable to new energy vehicles. For example, during the AC slow charging process of the vehicle power battery, the embodiment of the present application is used to control the charging electronic lock to unlock and lock (also called lock). Figure 1 Schematic diagram of the control system of a charging electronic lock provided in an embodiment of the present application. Figure 1 As shown, the system includes: an on-board charging and discharging distribution unit (Conversion Distribution Unit, CDU) 11, a battery management system (Battery Management System, BMS) 12, a front left zone controller (Front Left Zone Control Unit, FLZCU) 13, an integrated cockpit controller (Integrated Cockpit Controller, ICC) 14, a charging gun (such as 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 unit, monitoring the status of the battery, preventing the battery from overcharging and over-discharging, so as to extend the battery life; FLZCU13 is used to provide power mode control function and vehicle disarming status management function; 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. Among them, 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 of the charging electronic lock is described in detail through the following implementation.

[0103] Figure 2 This is a flow chart of a control method for a charging electronic lock provided in an embodiment of the present application. The execution subject of this method is the CDU on the vehicle, see Figure 2 , the method comprises the following steps:

[0104] 201. The CDU obtains a battery charging status and a vehicle status; wherein the battery charging status is used to indicate whether a charging failure occurs in the vehicle; and the vehicle status at least includes a vehicle disarmed status and a vehicle thermal runaway status.

[0105] The first point that needs to be explained is that if a charging failure occurs in the vehicle, the vehicle power battery cannot be charged, and the vehicle is in a battery uncharged state; if no charging failure occurs in the vehicle, the vehicle power battery can be charged, and the vehicle is in a battery charged state.

[0106] The second point that needs to be explained is that the vehicle disarmed state is used to indicate whether the anti-theft system on the vehicle is turned on. Among them, the vehicle armed state refers to an anti-theft protection state that the vehicle enters through the remote control key or vehicle system settings after closing all doors and charging port covers. In this state, if the door or charging port cover is opened illegally, the anti-theft system will trigger an alarm to warn and deter potential intruders. The vehicle disarmed state is the opposite, which means disarming the vehicle, and disarming the vehicle usually means turning off the anti-theft system on the vehicle so that the vehicle can be restored to a normal drivable state.

[0107] The third point that needs to be explained is that the vehicle's thermal runaway status is used to indicate whether the vehicle has a thermal runaway failure.

[0108] 202. The CDU obtains a method for unlocking the charging electronic lock.

[0109] In the embodiments of the present application, the unlocking methods of the charging electronic lock include but are not limited to: manual pull ring unlocking, mobile phone APP remote unlocking, and vehicle ICC soft switch unlocking, which are not limited in the present application.

[0110] The fourth point to be explained is that after obtaining the above information through the above steps 201-202, Figure 3 The state flow diagram shown is used to control the working state of the charging electronic lock, as shown 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 the working state according to at least one of the battery charging state, the vehicle state, the unlocking mode of the charging electronic lock, or the fault condition of the charging electronic lock.

[0112] Exemplarily, the working state of the charging electronic lock includes an unlocked state and a locked state. Furthermore, the unlocked state is further subdivided into a first unlocked state and a second unlocked state. The difference between these two unlocking states is that in the first unlocked state, the unlocking time of the charging electronic lock is not limited. In the second unlocked state, the unlocking time of the charging electronic lock is a preset time. That is, after the preset time, the charging electronic lock automatically returns to the locked state. Exemplarily, the value of the preset time is 30 seconds, that is, unlocked for 30 seconds, and the charging electronic lock automatically returns to the locked state after 30 seconds.

[0113] Combine the following Figure 3 Scenes 1 to 5 are shown to introduce how to control the charging electronic lock to switch the working state.

[0114] Scenario 1: Switching from the first unlocked state to the locked state.

[0115] For this scenario, if the current working state of the charging electronic lock is the first unlocked state, then any one of the following conditions is met, and the charging electronic lock is controlled to switch from the first unlocked state to the locked state.

[0116] Condition 1: The charging gun is connected to the vehicle charging port, the CDU receives the target status information or battery heating request sent by the BMS, and the charging electronic lock is not faulty.

[0117] Exemplarily, the charging gun mentioned in this article is a charging gun for AC slow charging, which is not limited in this application. The target state information is used to indicate that the battery is in a charging state or a pre-charging state.

[0118] Exemplarily, if the charging gun for AC slow charging is connected to the vehicle charging interface, and the CDU receives status information sent by the BMS indicating that the battery is in a charging state, and the charging electronic lock has no faults, the CDU drives the charging electronic lock to lock.

[0119] Condition 2: The vehicle is in the armed state, the charging gun is connected to the vehicle charging port, the charging electronic lock is not faulty, and the vehicle has no thermal runaway fault.

[0120] Exemplarily, if the vehicle is in the armed state, and the charging gun for AC slow charging is connected to the vehicle charging port, and the charging electronic lock is in good condition, and the vehicle has no thermal runaway fault, the CDU drives the charging electronic lock to lock.

[0121] In addition, if the charging electronic lock fails in the scenario, it will not enter the locked state, and the charging current needs to be controlled below the first value. After the fault is restored, if the conditions for entering the locked state are met, the charging electronic lock is driven to lock and the charging current is restored. For example, the first value is 16A, which is not limited in this application.

[0122] Scenario 2: Switching from the locked state to the first unlocked state.

[0123] For this scenario, if the current working state of the charging electronic lock is the locked state, then any one of the following conditions is met, and the charging electronic lock is controlled to switch from the locked state to the first unlocked state.

[0124] Condition 1: The vehicle is currently in the disarmed state, and the CDU receives the charging completion signal sent by the BMS, and the charging electronic lock is not faulty.

[0125] For example, when the charging electronic lock is not faulty and the vehicle is in an unlocked state, the CDU drives the charging electronic lock to unlock after receiving a charging completion signal sent by the BMS.

[0126] Condition 2: The vehicle is currently in the disarmed state, the S3 switch on the charging gun is pressed, and the charging electronic lock is not faulty.

[0127] For example, when the charging electronic lock is not faulty, if the vehicle is in the disarmed state, after the S3 switch is pressed, the vehicle enters the unlocked state and drives the charging electronic lock to unlock.

[0128] Condition 3: The vehicle is currently in the disarmed state, the battery is currently not charged, and the charging electronic lock is not faulty.

[0129] Exemplarily, when there is no failure in the charging electronic lock, if the vehicle is in the disarmed state and the battery cannot be charged due to a charging failure, the vehicle enters the unlocked state and drives the charging electronic lock to unlock.

[0130] Condition 4: The vehicle is currently in the disarmed state, and the charging stop operation is detected, and the charging electronic lock is not faulty.

[0131] Exemplarily, when there is no fault in the charging electronic lock, if the vehicle is in the disarmed state and charging is actively stopped (for example, the power supply to the charging pile is cut off), the vehicle enters the unlocked state and drives the charging electronic lock to unlock.

[0132] Condition 5: Manual pull ring unlocks.

[0133] Among them, if the charging electronic lock does not malfunction, if the user manually pulls the ring to unlock it, it enters the unlocking state and drives the charging electronic lock to unlock.

[0134] Condition 6: The vehicle suffers from thermal runaway failure.

[0135] Among them, when a thermal runaway fault occurs in the vehicle, if the CDU receives a thermal runaway signal sent by the BMS, it enters the unlocking state and drives the charging electronic lock to unlock.

[0136] In addition, if the charging electronic lock switches from the locked state to the first unlocked state due to a thermal runaway fault of the vehicle, the charging electronic lock is prohibited from switching to the locked state within a preset number of ignition cycles. For example, the preset number is 1, and this application does not limit this.

[0137] Scenario 3: Switching from the locked state to the second unlocked state.

[0138] For this scenario, if the current working state of the charging electronic lock is the locked state, then any one of the following conditions is met, and the charging electronic lock is controlled to switch from the locked state to the second unlocked state.

[0139] Condition 1: Remote unlocking of the application.

[0140] For example, if the remote unlocking is performed through a mobile phone APP, the CDU enters the second unlocking state after receiving the remote unlocking signal sent by the T-BOX module, drives the charging electronic lock to unlock, and performs timing.

[0141] Condition 2: Unlock via the virtual switch displayed on the vehicle screen.

[0142] Exemplarily, if the vehicle is unlocked through the 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 the armed state to the disarmed state.

[0144] For example, if the vehicle switches from the armed state to the disarmed state, the CDU enters the second unlocked state after receiving the transition edge of the vehicle switching from the armed state to the disarmed state, drives the charging electronic lock to unlock, and performs timing.

[0145] In addition, after the charging electronic lock switches from the locked state to the second unlocked state, if the battery is currently in the charging state, the charging current is controlled below the second value. For example, the second value is 16A, which is not limited in this application. In addition, after the unlocking time exceeds the preset time, if the conditions for entering the locked state are met, the charging electronic lock is driven to lock and the charging current is restored.

[0146] Scenario 4: Switching from the second unlocked state to the first unlocked state.

[0147] For this scenario, if the current working state of the charging electronic lock is the second unlocking state, any of the following conditions is met, and the charging electronic lock is controlled to switch from the second unlocking state to the first unlocking state.

[0148] Condition 1: No charging connection confirmation signal is detected and the charging electronic lock is not faulty.

[0149] Exemplarily, if the CC signal is not detected (for example, the S3 switch is pressed or the gun is drawn within 30 seconds of unlocking), the first unlocking state is entered, and the charging electronic lock is driven to unlock.

[0150] Condition 2: Charging is completed in the second unlocked state, the charging gun is connected to the vehicle charging port, and the charging electronic lock is not faulty.

[0151] For example, when the charging gun is in a connected state and the charging electronic lock is not faulty, if charging is completed within 30 seconds of unlocking, the CDU drives the charging electronic lock to unlock after receiving the charging completion signal sent by the BMS.

[0152] Condition 3: The vehicle is in the disarmed state, and a charging failure occurs or a charging stop operation is detected in the second unlocked state, and the charging electronic lock is not faulty.

[0153] For example, when the vehicle is in the disarmed state, if charging is unable to be performed or charging is actively stopped within 30 seconds of unlocking, the CDU drives the charging electronic lock to unlock.

[0154] Condition 4: Manually unlock the pull ring.

[0155] Condition 5: The vehicle experiences thermal runaway failure in the second unlocked state.

[0156] For example, if a thermal runaway fault occurs in the vehicle within 30 seconds of unlocking, the CDU drives the charging electronic lock to unlock after receiving the thermal runaway signal sent by 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 of the vehicle, the charging electronic lock is prohibited from switching to the locked state within a preset number of ignition cycles.

[0158] Scene 5: Switching from the second unlocked state to the locked state.

[0159] For this scenario, if the current working state of the charging electronic lock is the second unlocking state, any of the following conditions is met, and the charging electronic lock is controlled to switch from the second unlocking state to the locking state.

[0160] Condition 1: After the unlocking time exceeds the preset time, the charging gun is connected to the vehicle charging port and the charging electronic lock is not faulty.

[0161] For example, after the unlocking time exceeds 30 seconds, if the charging gun for AC slow charging is in the connected state, it enters the locked state, and the CDU drives the charging electronic lock to lock. In this step, the unlocking method can be unlocking by mobile phone APP, unlocking by large screen soft switch, or switching the vehicle from the armed state to the disarmed state.

[0162] Condition 2: The vehicle switches from the disarmed state to the armed state, the charging gun is connected to the vehicle charging port, and the charging electronic lock is not faulty.

[0163] In addition, in scenario five, if the battery is in a charging state, the charging current is restored after the state transition is performed, that is, after entering the locked state.

[0164] In summary, during the charging process of new energy vehicles, the embodiments of the present application realize intelligent state control of the charging electronic lock. In detail, after confirming the current working state of the charging electronic lock, the embodiments of the present application can intelligently and accurately control the charging electronic lock to switch the working state according to at least one of the battery charging state, vehicle state (such as vehicle disarmed state, vehicle thermal runaway state), unlocking method of the charging electronic lock, or fault conditions. This method of controlling the working state of the charging electronic lock based on diversified data can not only improve the charging efficiency but also achieve safe charging.
