[0064] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0065] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions 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 only 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, including but not limited to the combination of multiple embodiments, belong to the scope of protection of this application.

[0066] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0067] When charging of existing electric vehicles is finished, the user needs to stop the charging through the charging pile or the screen on the mobile phone or the stop button on the charging gun, and then wait for the voltage or current to drop to 0 before unlocking the charging gun. Only then can the user pull out the charging gun. In the prior art, both the owner and non-owner can unlock and pull out the gun. Even if the operation is optimized to only click one button, the user still feels that the waiting time is too long, and there is an obvious pause and waiting phenomenon, which gives the user a feeling of slow response and greatly affects the user experience.

[0068] In addition, in the prior art, non-owners can also stop charging and unplug the gun, which may lead to malicious interruption of charging and malicious unplugging of the gun, and the owner cannot fully charge the electric vehicle. This will affect the integrity and safety of charging.

[0069] That is, the prior art has the technical problems that the time period from issuing the command to end charging to unlocking the charging gun is too long, and non-car owners may maliciously interrupt charging and pull out the gun.

[0070] To solve the above problems, the inventive concept of this application is:

[0071] From the time the user presses the stop button to the time the voltage or current drops to a sufficiently small safety threshold, the locking state of the vehicle is obtained in parallel to determine whether the charging gun can be unlocked. In this way, the serial processing method in the prior art can be changed to parallel processing, which greatly reduces the waiting time of the user. Before or when the voltage or current drops to the safety threshold, the charging gun can be unlocked, so that the user can feel that it can be stopped and the gun can be drawn at once, and it is done in one go, and basically no delay or pause can be felt, which improves the user's experience. And the ability to stop and draw the gun at the same time allows users to drive away as quickly as possible when dealing with emergencies, providing protection for users to avoid danger in an emergency. It can also solve the situation where non-owners maliciously stop charging and draw the gun, because non-owners cannot unlock the vehicle without the vehicle key.

[0072] In addition, in a possible design, whether it is a dedicated protocol vehicle with a dedicated protocol or a non-dedicated protocol vehicle, it can be set to: long press the charging gun micro switch for a preset time such as 1s to directly stop charging and unlock the charging gun, that is, allow the user to unplug the charging gun, so that vehicles with different charging protocols can be adapted to stop charging of vehicles with different protocols and allow users to unplug the charging gun.

[0073] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0074] Figure 1 A schematic diagram of an application scenario of vehicle charging control provided in an embodiment of the present application. Figure 1 As shown, the charging pile 1 is connected to the charging socket 7 on the body of the electric car 8 through the charging cable 3 and the charging gun 4. The charging gun 4 is provided with a micro switch 5 and an electronic lock 6, the charging pile 1 is provided with an ECU (Electronic Control Unit) electronic controller 2, and the electric car 8 is also provided with an ECU electronic controller 9 and a BMS (Battery Management System) battery management system 10.

[0075] The following is a detailed introduction on how to implement the vehicle charging control method provided by this application.

[0076] Figure 2 A flow chart of a vehicle charging control method provided in an embodiment of the present application. Figure 2 As shown, the vehicle charging control method is applied to a charging pile, and the specific steps include:

[0077] S201: When the vehicle is in charging state, if the charging gun detects that the user has made a preset trigger action, a stop command is sent to the charging module.

[0078] In this step, the vehicle is in a charging state when: Figure 1 As shown, before the electric car 8 is fully charged, the charging pile 1 charges the electric car 8 via the charging gun 4 .

[0079] The preset triggering action includes at least one of: grasping the handle of the charging gun, pressing the micro switch 5 on the charging gun, and the hand passing through the gesture sensing area when reaching out to the charging gun.

[0080] It should be noted that when grasping the handle of the charging gun, the preset trigger action can be detected by setting a pressure sensor on the handle; the electrical signal generated by the micro switch 5 when being pressed can detect the preset action; when the hand passes through the posture sensing area, the preset trigger action can be detected by the image acquisition device (such as a camera, infrared spectrometer) or radar on the charging gun.

[0081] like Figure 1 As shown, the ECU electronic controller 2 of the charging pile receives a trigger signal that the charging gun detects a preset trigger action, and then sends a stop command to the charging module inside the charging pile, such as the AC-DC (Alternating Current to Direct Current) conversion module, to stop the output of charging energy.

[0082] It should be noted that due to the physical characteristics of electric energy and the shutdown characteristics of the charging module, when it stops, it does not ideally become 0 directly, but needs to go through a period of time to fall. This is also the fundamental reason why the existing technology will cause a delay when the charging is turned off.

[0083] S202: While sending the stop command, or when it is detected that the output state of the charging module begins to change and the output state has not yet reached a preset safety state, determine whether the vehicle is locked based on the received door state signal in parallel.

[0084] In this step, two implementation methods are included. One is that the ECU electronic controller 2 of the charging pile sends a stop command to the charging module and simultaneously determines whether the vehicle is unlocked; the other is that when the charging module receives the stop command and starts to cut off the charging energy supply, the output state of the charging module begins to change. At this time, there are also two methods. One is that the charging module feeds back a response signal to the ECU electronic controller 2, and the other is to monitor the output state of the output end in real time through the sensor at the output end of the charging module. If it is found that the output state of the output end begins to change, the ECU electronic controller 2 synchronously and in parallel determines whether the vehicle is unlocked.

[0085] Specifically, the implementation method of determining whether the vehicle is unlocked includes: Figure 1 As shown, after charging starts and the charging gun 4 is connected to the vehicle charging socket 7 , the electric car 8 starts to periodically send a door status signal to the ECU electronic controller 2 on the charging pile 1 .

[0086] Compared with the methods and techniques in the prior art of first receiving a door status signal, then issuing a stop command, and finally waiting for the charging module to shut down and fall to a safe range, the method of the embodiment of the present application of concurrently determining whether the vehicle is unlocked can greatly save waiting time.

[0087] It should be noted that in the prior art, the vehicle is not locked until the output voltage or output current of the charging module drops to 0. This makes the user feel the delay obviously, and the system feels unresponsive, which affects the user experience. The present application changes this method. While waiting for the voltage / current output of the charging pile to drop, the judgment of whether the vehicle is locked is completed in parallel. The charging gun can be unlocked immediately when it drops to a safe range, greatly reducing the delay time. In addition, the user can unlock and pull out the charging gun as soon as possible in an emergency, and drive away for emergency avoidance. Because in an emergency, 1 second can be a matter of life and death.

[0088] If it is determined in parallel and synchronously that the vehicle has been unlocked, step S203 is executed, otherwise, step S204 is executed.

[0089] S203: When or before the preset safety state is reached, an unlocking instruction is sent to the locking mechanism so that the user can take out the charging gun.

[0090] In this step, when or before the preset safety state is reached, if it is determined that the vehicle has been unlocked, that is, the user has unlocked the vehicle with the car key, then an unlocking instruction is sent to the locking mechanism used to lock the connection between the vehicle and the charging gun, so that the unlocking mechanism changes from the locked state to the unlocked state, so that the user can remove the charging gun 4 from the charging socket 7 on the body of the electric car 8. It should be noted that the function of the locking mechanism is to prevent the charging gun from being pulled out during the charging process of the vehicle, that is, pulling out the gun with power on, which may cause a safety hazard of electric shock.

[0091] Optionally, a gun-drawing reminder light or a buzzer is provided on the charging gun, and the reminder light lights up or changes color, or the buzzer emits a buzzer when the gun can be drawn.

[0092] Furthermore, in order to avoid electric shock caused by the user pulling out the gun when the output state of the output end has not reached the preset safety state, if the user can unlock the gun before the preset safety state is reached, the locking mechanism can be unlocked synchronously when the preset safety state is reached. Alternatively, a prompt message that the user can draw the gun is output only when the preset safety state is reached.

[0093] In one possible design, when it is detected that the charging gun has not been removed from the vehicle within a first preset period of time, a locking command is sent to the locking mechanism to re-lock the charging gun; and an opening command is sent to the charging module to recharge the vehicle.

[0094] Specifically, if the user does not remove the charging gun 4 from the charging socket 7 of the electric car 8 within 5 to 10 seconds, for example, the contact sensor or contact switch of the charging socket 7 or the charging gun 4 detects that the charging gun is still connected to the charging socket 7, it is considered that the user has temporarily changed his intention, the charging gun is locked again, and charging is restarted.

[0095] Optionally, before sending a locking command to the locking mechanism, or before sending an opening command to the charging module, the battery level of the vehicle is detected. If the battery level is greater than a preset threshold, the vehicle is no longer locked and / or recharged.

[0096] S204: Maintain the locking state of the locking mechanism.

[0097] In this step, when or before the preset safety state is reached, if it is determined that the vehicle is not unlocked, that is, the user has not unlocked it with the vehicle key, it is possible that the owner does not want to end charging, but someone else wants to end charging without the owner's consent, or the owner forgets to unlock the vehicle. In either case, the locking mechanism will remain locked to prevent the charging gun from being pulled out.

[0098] Optionally, the vehicle can simultaneously send out a prompt message, such as turning on the double flash and / or honking the horn to remind the owner to unlock the vehicle. It can also send a text message to remind the owner that someone wants to unplug the charging gun so that the owner can conduct a safety check in time.

[0099] In one possible design, when the vehicle unlocking is not detected within the second preset time period, an opening instruction is sent to the charging module to recharge the vehicle.

[0100] Optionally, before sending a start command to the charging module, the battery level of the vehicle is detected, and if the battery level is greater than a preset threshold, recharging is no longer performed.

[0101] This embodiment provides a vehicle charging control method, by sending a stop command to the charging module when the vehicle is in the charging state, if the charging gun detects that the user has made a preset trigger action; at the same time as sending the stop command, or when it is detected that the output state of the charging module begins to change and the output state has not yet reached the preset safety state, it is judged in parallel based on the received door state signal whether the vehicle is locked; if not, an unlocking command is sent to the locking mechanism when or before the preset safety state is reached, so that the user can take out the charging gun; if so, the locking state of the locking mechanism is maintained. After the stop charging command is issued, the charging gun is unlocked during the process of the output state of the charging module decreasing, which solves the technical problem of the prior art that the time period corresponding to the issuance of the command to end charging to the unlocking of the charging gun is too long. The charging gun can be stopped and pulled out as soon as it is pressed, which improves the user's experience.

[0102] Figure 3 A flow chart of another vehicle charging control method provided for the implementation of this application. Figure 3 As shown, the specific steps of the vehicle charging control include:

[0103] S301: When the vehicle is in a charging state, if the charging gun detects that the user has made a preset trigger action, a stop command is sent to the charging module.

[0104] The specific implementation principle and name explanation of this step can be referred to S201 and will not be repeated here.

[0105] S302. While sending a stop instruction, simultaneously obtain an output voltage and / or an output current of the charging module.

[0106] In this step, the output voltage and / or output current is detected by a voltage and / or current sensor at the output end of the charging module.

[0107] S303: Determine whether the output voltage and / or the output current begins to change and does not reach a preset safety voltage or a preset safety current.

[0108] In this step, when the output voltage and / or output current begins to decrease, it is determined that the output state begins to change, and when the output voltage does not reach the preset safety voltage, and / or the output current does not reach the preset safety current, it is determined that the output state has not yet reached the preset safety state.

[0109] It should be noted that the preset safety voltage and the preset safety current include: the limit values ​​of the DC voltage and DC current that the human body can withstand, such as a DC voltage of 36V and a DC current of 10mA.

[0110] Optionally, the preset safety voltage and the preset safety current are both 0, which is a preset safety state.

[0111] S304: Determine whether the vehicle is locked according to the received door status signal.

[0112] In this step, if yes, execute step S305, if no, execute step S306.

[0113] S305: When or before the preset safety state is reached, an unlocking instruction is sent to the locking mechanism so that the user can take out the charging gun.

[0114] S306: Maintain the locking state of the locking mechanism, and send notification information to the vehicle or the mobile user terminal, so as to output prompt information through the vehicle and / or the mobile user terminal.

[0115] In this step, the prompt information may be used to indicate that the vehicle is in a locked state, and / or to indicate that someone is trying to stop charging the vehicle.

[0116] S307: When it is detected that the output state reaches a preset safety state, a disconnection instruction is sent to the contactor to cut off the output of charging energy.

[0117] In this step, the contactor is used to output charging energy.

[0118] In this embodiment, regardless of whether the vehicle is locked as determined in S304, this step will be executed when the output state reaches the preset safety state. Figure 3 In the figure, step S307 is set corresponding to both steps S305 and S306.

[0119] S308: Detect whether the charging gun is removed from the vehicle within a first preset period of time.

[0120] In this step, if yes, then the process ends directly; if no, then the process proceeds to S309.

[0121] It should be noted that this step is performed in the case corresponding to S305, that is, when the vehicle has been unlocked.

[0122] S309: Send a locking instruction to the locking mechanism to re-lock the charging gun.

[0123] In this step, if the charging gun is not removed, it means that the user may have temporarily changed his mind or need to deal with other matters. At this time, in order to prevent the charging gun from being removed by others and stealing the vehicle when the owner is not paying attention, the charging gun is locked again with the charging socket on the vehicle.

[0124] S310: Send an on command to the charging module to recharge the vehicle.

[0125] In this step, if the user does not remove the charging gun within the first preset time period, such as 5 to 10 seconds, it can be understood that the owner may have triggered it by mistake or wanted to continue charging after stopping.

[0126] S311. Detect whether the vehicle is unlocked within a second preset time period.

[0127] In this step, if yes, execute S308, if no, execute S309.

[0128] It should be noted that this step is performed in the case corresponding to S306, that is, when the vehicle is not unlocked.

[0129] Specifically, the entire process of this embodiment includes:

[0130] When a user's electric car needs to be charged, the vehicle enters the charging position, removes the charging gun, inserts the charging gun into the vehicle charging socket, and connects the gun to the socket. The charging pile is turned on, and the charging pile starts charging the vehicle.

[0131] When the vehicle is unlocked, when charging needs to be terminated, press the gun micro switch, and the charging pile will drop from the charging voltage / current to a safe voltage / current or voltage / current to zero (about 3000ms). While the user presses the gun micro switch, the charging pile detects the door lock unlocking signal (about 1000ms). If it detects that the car has been unlocked (for example, the user has unlocked it in advance through the remote control key), the gun electronic lock will be controlled to unlock; if it detects that the car has not been unlocked, the user can be notified that the vehicle is locked through the vehicle screen or APP. If the user does not unlock the vehicle, the gun electronic lock cannot be released. In the process of the charging pile dropping from the charging voltage and / or current to a safe voltage / safe current, or the voltage and / or current dropping to zero, the door unlocking signal is received at the same time and the gun electronic lock is unlocked after interpretation and processing. The user can draw the gun and drive the electric car away.

[0132] For ease of understanding, the following Figure 1 The following scenario is used as an example:

[0133] like Figure 1 As shown, when the user needs to charge the electric vehicle, the user connects the charging gun 4 to the charging socket 7 on the electric vehicle 8. After the connection is reliable, the electronic lock 6 on the charging gun 4 is closed.

[0134] After charging starts, the door system 11 detects the door lock and unlock signal controlled by the car key, and sends the door lock status to the ECU electronic controller 9 after processing. The ECU electronic controller 9 sends the door lock status to the ECU electronic controller 2 in the charging pile 1 through the BMS battery management system 10 on the electric car 8 → charging socket 7 → charging gun 4. Or the ECU electronic controller 9 sends the door lock status to the receiving device on the charging pile 1 by wireless means (radio frequency, Bluetooth, infrared, etc.) through the wireless transmitter on the door system, and the receiving device receives and processes it and sends it to the ECU electronic controller 2.

[0135] During the charging process, when the user needs to end charging, he presses the micro switch 5 on the charging gun 4, and the ECU electronic controller 2 in the charging pile 1 receives the trigger signal of the micro switch 5 being pressed, and issues a command for its internal charging module to stop output. When the output voltage and / or current drops to a safe voltage / current or the voltage and / or current is zero, the ECU electronic controller 2 of the charging pile 1 controls the contactor for energy output to the electric vehicle 8 to disconnect, and stops the charging energy output to the electric vehicle 8.

[0136] If the user needs to leave, unlock the electric car 8, and the door lock is unlocked, the ECU electronic controller 2 detects that the door lock is unlocked after the stop output command is issued, and then releases the electronic lock 6, allowing the user to remove the charging gun to end charging, so that the user can drive the electric car away. If the user does not remove the charging gun after pressing the charging gun micro switch 5 for a certain period of time (10s), the ECU electronic controller 2 detects that the charging gun 4 is connected to the charging socket 7, then closes the electronic lock, restarts the charging pile, and continues to charge the electric car 8.

[0137] If the user plugs in the gun to charge and then locks the car and leaves, the door lock is in the locked state. After the ECU electronic controller 2 sends the stop output command, it detects that the door lock state is locked, and keeps the electronic lock closed. After a certain period of time (10s), the charging pile is restarted to continue charging the electric car 8.

[0138] This embodiment provides a vehicle charging control method, by sending a stop command to the charging module when the vehicle is in the charging state, if the charging gun detects that the user has made a preset trigger action; while sending the stop command, or when it is detected that the output state of the charging module begins to change and the output state has not yet reached the preset safety state, it is judged in parallel whether the vehicle is locked according to the received door state signal; if not, when or before the preset safety state is reached, an unlocking command is sent to the locking mechanism so that the user can take out the charging gun; if so, the locking state of the locking mechanism is maintained. After the stop charging command is issued, the unlocking of the charging gun is completed during the process of the output state of the charging module decreasing. Compared with the method and technology of first receiving the door state signal, then issuing the stop command, and finally waiting for the charging module to stop and fall to the safe range, it can greatly save waiting time and solve the technical problem of the long time period from issuing the command to end charging to unlocking the charging gun in the prior art. And solve the situation that non-owners (the vehicle cannot be unlocked without a key) maliciously stop charging and pull out the gun; realize the technical effect that the charging gun can be pulled out after pressing and stopping, and improve the user experience. In addition, whether it is a dedicated protocol vehicle or a non-dedicated protocol vehicle, long pressing the charging gun micro switch for 1s (settable) can directly stop charging and unlock to allow the gun to be pulled out. It can adapt to vehicles with different charging protocols and realize charging and gun pulling out of vehicles with different protocols.
