Background Art

[0002] With the popularity of new energy electric vehicles, one of the scenarios that electric vehicle owners have to face is charging their electric vehicles. Currently, the charging cover of electric vehicles needs to be opened manually, and after charging is completed, the charging cover still needs to be manually closed, which causes inconvenience.

[0003] Summary of the Invention

[0004] In response to the above-mentioned problems in the prior art, the present invention proposes a charging cover automatic opening and closing method, an automatic opening and closing system, an automatic opening and closing device and a computer-readable storage medium, which can automatically open and close the charging cover before and after the charging gun is plugged in and out, thereby improving the user experience.

[0005] Specifically, the present invention proposes a method for automatically opening and closing a charging cover, which is applicable to a charging vehicle, wherein the charging cover is used to shield a charging port of the charging vehicle, comprising the steps of:

[0006] S1, detecting whether there is a command signal, where the command signal includes at least an ID of the charging gun and a low-frequency command characteristic value, where the low-frequency command characteristic value is used to represent the state of the charging gun, where the state of the charging gun includes at least a suspended state;

[0007] S2, identifying the command signal, and if the low-frequency command characteristic value in the command signal is in a suspended state, determining whether a charging cover opening condition is met based on the command signal, and if so, generating a charging cover opening instruction;

[0008] S3, executing a charging cover opening instruction according to the operating state of the charging vehicle to open the charging cover.

[0009] According to one embodiment of the present invention, the method for automatically opening and closing the charging cover further includes the steps of:

[0010] S4, the charging gun status also includes the state of being inserted into the charging port, detecting whether there is a command signal, and if so, identifying whether the low-frequency command characteristic value in the command signal indicates that the charging gun is inserted into the charging port, and if so, proceeding to step S5;

[0011] S5, determine whether the source of the current command signal is consistent with the command signal obtained in step S1, and detect whether there is an insertion signal on the vehicle side. The insertion signal is used to indicate that the charging gun is inserted into the charging port. If the source of the command signal is consistent and / or the insertion signal exists, the charging pairing is successful.

[0012] According to one embodiment of the present invention, the method for automatically opening and closing the charging cover further includes the steps of:

[0013] S6, detecting whether there is a pull-out signal on the vehicle side, the pull-out signal is used to indicate that the charging gun is pulled out of the charging port, if so, proceeding to step S7;

[0014] S7, detecting whether a command signal exists, and if so, determining whether a low-frequency command characteristic value in the command signal is in a suspended state, and if so, determining that the charging gun has been unplugged from the charging port;

[0015] S8, determining whether the charging cover closing condition is met, and if so, generating a charging cover closing instruction;

[0016] S9, executing the charging cover closing instruction to close the charging cover.

[0017] According to an embodiment of the present invention, the command signal is a continuous periodic signal. In step S2, the charging cover opening condition is that the accumulated number of the command signals reaches a set value.

[0018] According to an embodiment of the present invention, in step S5, if the current command signal and the command signal obtained in step S1 contain the same charging gun ID, it is determined that the two have the same source.

[0019] According to one embodiment of the present invention, in step S3, a charging cover opening instruction is executed according to the operating state of the charging vehicle to open the charging cover.

[0020] According to one embodiment of the present invention, in step S8, the charging cover closing condition is that no low-frequency command characteristic value is detected as a command signal inserted into the charging port within a set time period.

[0021] According to one embodiment of the present invention, in step S8, the command signal is no longer detected within a set time period after the charging cover closing instruction is generated.

[0022] The present invention also provides a charging cover automatic opening and closing system, which is applicable to the aforementioned charging cover automatic opening and closing method, and the charging cover automatic opening and closing system includes a charging pile and a charging vehicle;

[0023] The charging pile includes a charging pile body and a charging gun, and the charging gun includes a status detection module and a signal transmitter. The status detection module is used to detect the status of the charging gun to generate the low-frequency command characteristic value. The status detection module generates the command signal based on the ID and status of the charging gun, and the signal transmitter sends the command signal to the outside.

[0024] The charging vehicle includes a charging induction device, a signal receiving unit, a charging control unit and an action execution unit. The charging induction device is used to detect the command signal. The signal receiving unit sends the command signal detected by the charging induction device to the charging control unit. The charging control unit identifies the ID of the charging gun and the low-frequency command characteristic value contained in the command signal. If the low-frequency command characteristic value in the command signal is in a suspended state, it is determined based on the command signal whether the charging cover opening condition is met. If so, a charging cover opening instruction is generated, and the action execution unit opens the charging cover according to the charging cover opening instruction.

[0025] According to one embodiment of the present invention, the charging gun state also includes a state of being inserted into a charging port;

[0026] After the charging cover is opened, the signal receiving unit continuously sends the command signal detected by the charging induction device to the charging control unit. The charging control unit identifies the charging gun ID and low-frequency command characteristic value in the current command signal. If the low-frequency command characteristic value indicates that the charging gun is inserted into the charging port, the charging control unit determines whether the source of the current command signal is consistent with the command signal before the charging cover is opened.

[0027] The charging vehicle further includes a body detection unit, which is used to detect whether there is an insertion signal, and the insertion signal is used to indicate that the charging gun is inserted into the vehicle charging port;

[0028] If the charging control unit determines that the sources of the command signals are consistent and / or receives the insertion signal, it is confirmed that the charging pairing is successful.

[0029] According to one embodiment of the present invention, the vehicle body detection unit is further configured to detect whether there is a pull-out signal, wherein the pull-out signal is used to indicate that the charging gun is pulled out of the vehicle charging port;

[0030] If the charging control unit receives the unplug signal and identifies that the low-frequency command characteristic value contained in the current command signal is in a suspended state, it determines that the charging gun has been unplugged from the charging port; after determining that the charging gun has been unplugged from the charging port, the charging control unit determines whether a charging cover closing condition is met, and if so, generates a charging cover closing instruction;

[0031] The action execution unit closes the charging cover according to the charging cover closing instruction.

[0032] According to an embodiment of the present invention, the action execution unit executes a charging cover opening instruction to open the charging cover according to the operating state of the charging vehicle.

[0033] The present invention also provides an automatic opening and closing device for a charging cover, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the steps of any of the aforementioned methods for automatically opening and closing the charging cover are implemented.

[0034] The present invention also provides a computer-readable storage medium having a computer program stored thereon, wherein when the computer program is executed by a processor, the steps of any of the aforementioned methods for automatically opening and closing the charging cover are implemented.

[0035] The present invention provides a charging cover automatic opening and closing method, automatic opening and closing system, automatic opening and closing device and computer-readable storage medium. Based on the charging gun ID and low-frequency command characteristic value contained in the command signal, the charging cover is automatically opened and closed, which facilitates charging operations and improves user experience.

[0047] Figure 1 shows a flowchart of a method for automatically opening and closing a charging cover according to an embodiment of the present invention. As shown in the figure, the present invention provides a method for automatically opening and closing a charging cover for a charging vehicle. The charging cover is used to shield the charging port of the charging vehicle. The automatic opening and closing method includes the following steps:

[0048] S1. Detect whether a command signal exists. The command signal includes at least the charging gun ID and a low-frequency command characteristic value. The charging gun ID is its unique identification number. Each charging gun has a unique identification number. The low-frequency command characteristic value is used to characterize the current state of the charging gun, which includes at least a suspended state. This suspended state is distinct from other states of the charging gun, such as when the charging gun is plugged into a charging station or inserted into a vehicle's charging port.

[0049] S2, identifying the command signal. If the low-frequency command characteristic value in the command signal is in a suspended state, determining whether the charging cover opening condition is met based on the command signal. If so, generating a charging cover opening instruction;

[0050] S3, executing the charging cover opening instruction to open the charging cover.

[0051] It is easy to understand that with the above-mentioned automatic opening and closing method, when the charging gun is unplugged from the charging pile and when the charging gun is close to a stationary vehicle, the vehicle can recognize the charging gun and automatically open the charging cover.

[0052] Preferably, the method for automatically opening and closing the charging cover further comprises the steps of:

[0053] S4: The charging gun status also includes the status of being inserted into the vehicle's charging port. Detect whether there is a command signal. If so, identify whether the low-frequency command characteristic value in the command signal indicates that the charging gun is inserted into the charging port. If so, proceed to step S5:

[0054] S5 determines whether the current command signal and the command signal obtained in step S1 have the same source, and detects whether an insertion signal exists on the vehicle side. The insertion signal is used to indicate that the charging gun is inserted into the charging port. If the source of the command signal is consistent and / or the insertion signal exists, the charging pairing is successful. A successful charging pairing indicates that the charging gun and the vehicle are operating smoothly and can charge the vehicle's power battery. In this embodiment, the preferred solution is to determine whether the command signal source is consistent and whether an insertion signal exists on the vehicle side to ensure that the charging gun and vehicle are fully matched and avoid misoperation.

[0055] Preferably, the method for automatically opening and closing the charging cover further comprises the steps of:

[0056] S6, detecting whether there is a pull-out signal on the vehicle side, which indicates that the charging gun is pulled out of the charging port. If so, proceed to step S7;

[0057] S7: Checks for a command signal. If so, determines whether the low-frequency command characteristic value in the command signal indicates a suspended state. If so, the charging gun is determined to be unplugged from the charging port. The charging gun is in a suspended state before and after being plugged into the charging port, and the corresponding low-frequency command characteristic value in the command signal should indicate a suspended state. Step S6 confirms the presence of a disconnect signal from the vehicle, and step S7 confirms that the charging gun is in a suspended state to ensure that the charging gun completes the charging operation.

[0058] S8, determining whether the charging cover closing condition is met, and if so, generating a charging cover closing instruction;

[0059] S9: Execute the charging cover close command to close the charging cover. At this point, regardless of the operating state of the charging vehicle, the charging cover close command must be executed. If the charging cover cannot be closed, a charging cover not closed alarm is generated.

[0060] Preferably, the command signal is a continuous periodic signal. In step S2, the condition for opening the charging cover is that the cumulative number of command signals reaches a set value. Specifically, the command signals for the same ID can be accumulated and then judged whether a threshold is reached. The corresponding application scenario is that a lower threshold can be set for private paired charging piles, that is, only a lower set number value needs to be reached to meet the charging cover opening condition, thereby improving the user experience. For public charging piles, a relatively high threshold can be set to ensure the user experience while preventing the charging cover from being accidentally opened by other vehicles charging.

[0061] Preferably, in step S5, if the current command signal and the command signal obtained in step S1 contain the same charging gun ID, it is determined that the two have the same source, ensuring that the charging gun before and after the insertion operation is the same, thereby avoiding misoperation.

[0062] Preferably, in step S3, a charging lid opening instruction is executed based on the operating state of the charging vehicle to open the charging lid. The vehicle operating state includes two states: stationary and moving. If the vehicle is stationary, the charging lid opening instruction is executed. If the vehicle is moving, the charging lid opening instruction is not executed.

[0063] Preferably, in step S8, the charging cover closing condition is that no low-frequency command characteristic value indicating insertion into the charging port is detected within a set time period. This step is intended to prevent the charging gun from being inserted into the charging port while conflicting with a possible command to close the charging cover, thereby avoiding mechanical damage to the charging gun and charging cover.

[0064] Preferably, in step S8, no further command signals are detected for a set period of time after the charging cover close instruction is generated. This step is to prevent the charging cover from being re-generated after the charging cover is closed and a command signal related to a charging gun that has already completed a charging operation is detected again. The set period is preferably 5 seconds to prevent the charging cover from being reopened.

[0065] Figure 2 shows a schematic diagram of the structure of an automatic charging cover opening and closing system according to one embodiment of the present invention. Figure 3 shows a schematic diagram of an application scenario according to one embodiment of the present invention. As shown in the figure, the present invention also provides an automatic charging cover opening and closing system 200 for implementing the aforementioned automatic charging cover opening and closing method. The automatic charging cover opening and closing system 200 includes a charging station 201 and a charging vehicle 206.

[0066] Among them, the charging pile 201 includes a charging pile body 202 and a charging gun 203, and the charging gun 203 includes a status detection module 204 and a signal transmitter 205. The status detection module 204 is used to detect the status of the charging gun 203 to generate a low-frequency command characteristic value. The status detection module 204 generates a command signal based on the ID and status of the charging gun 203. The signal transmitter 205 sends a command signal to the outside. Conventionally, when the charging gun 203 is inserted into the charging pile body 202, the signal transmitter 205 is in a silent state and does not send a command signal. When the charging gun 203 leaves the charging pile body 202, the signal transmitter 205 enters an automatic low-frequency signal transmission mode, or a manual low-frequency signal transmission mode (for example, operated by a button trigger), which is used to continuously and periodically send a low-frequency signal containing the ID and status of the charging gun 203.

[0067] Furthermore, charging vehicle 206 includes a charging sensor 207, a signal receiving unit 208, a charging control unit 209, and an action execution unit 210. The charging sensor 207 can be located near the vehicle's charging cover and is used to detect (sensing) command signals from the charging gun 203 near the charging cover of the charging vehicle 206. The charging sensor 207 is also used to convert the received low-frequency signal into a high-frequency signal to facilitate subsequent processing. The signal receiving unit 208 transmits the command signal detected by the charging sensor 207 to the charging control unit 209 via the CAN bus. The signal receiving unit 208 is preferably a high-frequency RF receiving module or a bus (CAN, Lin, K) receiving module. The signal receiving unit 208 also includes a storage unit for storing historical IDs of the charging gun 203. The charging control unit 209 identifies the charging gun 203 ID and low-frequency command feature value contained in the command signal. If the low-frequency command feature value in the command signal indicates a floating state, the charging control unit 209 determines whether the charging cover opening condition is met based on the command signal. If so, it generates a charging cover opening instruction. The action execution unit 210 receives a charging cover opening instruction via the Lin bus, and executes the charging cover opening instruction to open the vehicle charging cover.

[0068] Preferably, the status of the charging gun 203 also includes the state of being inserted into the charging port. The status detection module 204 generates a command signal based on the ID and current state of the charging gun 203. The signal transmitter 205 continuously and periodically transmits the command signal. Although the command signal is still a low-frequency signal, the low-frequency command characteristic value contained therein varies depending on the state of the charging gun 203.

[0069] After the charging cover is opened, the signal receiving unit 208 continues to send the command signal detected by the charging induction device 207 to the charging control unit 209. The charging control unit 209 identifies the ID of the charging gun 203 and the low-frequency command characteristic value in the current command signal. If the low-frequency command characteristic value indicates that the charging gun 203 is inserted into the charging port, the charging control unit 209 determines whether the source of the current command signal is consistent with the command signal before the charging cover was opened. This ensures the consistency of the charging gun 203 before and after insertion, and avoids possible subsequent misoperation.

[0070] The charging vehicle 206 further includes a vehicle body detection unit 211 , which is used to detect whether there is an insertion signal, where the insertion signal is used to indicate that the charging gun 203 is inserted into the vehicle charging port.

[0071] If the charging control unit 209 determines that the command signal sources are consistent and / or receives an insertion signal, the charging gun and the charging vehicle are successfully paired. Successful pairing is determined based on the command signal from the charging gun 203 and the insertion signal from the vehicle. A preferred approach is to determine that the command signal sources are consistent and that the vehicle receives an insertion signal to ensure that subsequent charging operations proceed normally and avoid misoperation.

[0072] Preferably, the vehicle body detection unit 211 is further used to detect whether there is an unplug signal, which is used to indicate that the charging gun 203 is unplugged from the vehicle charging port;

[0073] If the charging control unit 209 receives the unplug signal and identifies the low-frequency command characteristic value contained in the current command signal as a suspended state, it determines that the charging gun 203 has been unplugged from the charging port. After determining that the charging gun 203 has been unplugged from the charging port, the charging control unit 209 determines whether the charging cover closing condition is met. If so, it generates a charging cover closing command. The unplug signal from the vehicle and the suspended state of the charging gun 203 confirm that the charging gun 203 has been unplugged from the vehicle's charging port, and then generates a charging cover closing command.

[0074] The action execution unit 210 closes the charging cover according to the charging cover closing instruction, so that the charging cover completes the automatic opening and closing action.

[0075] Preferably, the action execution unit 210 executes the charging cover opening instruction to open the charging cover according to the running state of the charging vehicle. If the vehicle is in a stationary state, the charging cover opening instruction is executed. If the vehicle is in a moving state, the charging cover opening instruction is not executed.

[0076] The following is a detailed description of the automatic opening and closing process of the charging cover in a specific application scenario in combination with all the accompanying drawings:

[0077] 1) The charging vehicle 206 stops at the charging parking space.

[0078] 2) The car owner gets off the car, and the state detection module 204 of the charging gun 203 detects that the charging gun 203 has left the charging pile body 202 and is in a suspended state.

[0079] 3) At this point, the status detection module 204 of the charging gun 203 generates a command signal containing the ID of the charging gun 203 and the low-frequency command characteristic value indicating that the charging gun 203 is in the suspended state. The signal transmitter 205 of the charging gun 203 continuously and periodically transmits this low-frequency command signal. In this embodiment, the ID of the charging gun 203 is 0xFE010102, and the low-frequency command characteristic value is A.

[0080] 4) When charging gun 203 approaches the charging port of vehicle 206 to be charged, it triggers charging induction device 207 installed at the charging port. Signal receiving unit 208 continuously transmits the low-frequency command signal detected by charging induction device 207 to charging control unit 209. Charging control unit 209 then determines whether the charging cover opening condition is met. The charging cover opening condition is that the signal received by charging induction device 207 contains a low-frequency signal with charging gun 203 ID 0xFE010102 and a low-frequency command characteristic value of A. If this signal is received n times cumulatively, the opening condition is considered met. Signal receiving unit 208 can be a tire pressure monitoring controller.

[0081] 5) After the start-up conditions are met, the charging control unit 209 sends a high-frequency signal with the charging gun 203 ID being 0xFE010102 and the high-frequency command characteristic value being A to the signal receiving unit 208;

[0082] 6) The signal receiving unit 208 is activated by the high-frequency signal and sends a command containing A (charging cover opening instruction) to the action execution unit 210 via the CAN bus. The action execution unit 210 opens the charging cover according to the operating status of the charging vehicle.

[0083] 7) The tire pressure controller sends command A to the charging cover control unit via the CAN bus, and the charging cover control unit sends command A via the Lin line to execute the action of opening the charging cover.

[0084] If, after the vehicle's charging lid is opened, no low-frequency command signal with a characteristic value of C is detected within a set time period, and no plug-in signal is detected on the vehicle side, the charging control unit 209 generates a charging lid closing command, and the action execution unit 210 closes the charging lid. The set time period is preferably 1 minute.

[0085] 8) When charging gun 203 (ID: 0xFE010102) is inserted into the vehicle's charging port, the status detection module 204 of charging gun 203 detects that charging gun 203 is currently inserted into the vehicle's charging port. At this point, the signal transmitter 205 of charging gun 203 periodically transmits a low-frequency signal with a low-frequency command characteristic value of C. Preferably, the low-frequency signal is transmitted for a period of 3 seconds, and after approximately 30 seconds, the transmission stops to conserve power consumption of charging gun 203.

[0086] 9) The low-frequency signal triggers the charging induction device 207, and the charging control unit 209 recognizes the low-frequency signal including the ID 0xFE010102 and the low-frequency command characteristic value C.

[0087] 10) During the process of opening the charging cover, the received ID is 0xFE010102 and the low-frequency command characteristic value is A. After that, the received ID is 0xFE010102 and the low-frequency command characteristic value is C.

[0088] 11) In addition, when the charging gun 203 is inserted into the charging port, the vehicle body detection unit 211 detects that the charging gun 203 has been inserted into the charging port and notifies the signal receiving unit 208 of the insertion signal via a CAN bus signal or a high-frequency signal.

[0089] 12) If the charging gun 203 ID received twice by the charging induction device 207 is the same ID and there is an insertion signal, it means that the charging gun 203 is successfully paired with the charging vehicle 206 and charging is performed.

[0090] 13) After the vehicle is fully charged, the owner unplugs the charging gun 203 (ID: 0xFE010102).

[0091] 14) The vehicle body detection module immediately recognizes the action and sends an unplug signal via a high-frequency signal or a CAN bus signal to wake up the signal receiving unit 208.

[0092] 15) The state detection module 204 of the charging gun 203 detects that the charging gun 203 has left the vehicle charging port and is in a suspended state, and the signal transmitting device 205 starts to send a command signal with a low-frequency command characteristic value of A.

[0093] 16) If the charging sensor 207 detects a low-frequency command signal with an A and the signal receiving unit 208 receives a removal signal, it indicates that the charging gun 203 has been removed from the charging port. When the charging gun 203 is removed from the charging port, the charging sensor 207 will no longer detect any low-frequency commands, and the vehicle body detection unit 211 will also be unable to detect the presence of the charging gun 203 in the charging port. After a 5-second wait, the charging cover automatically closes. After the charging gun 203 is inserted into the charging station body 202, the status detection module 204 detects this state for a short period of time, shutting down the signal transmitter 205 and ceasing to send low-frequency command signals.

[0094] The present invention also provides an automatic opening and closing device for a charging cover, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the steps of any of the aforementioned methods for automatically opening and closing a charging cover are implemented.

[0095] The present invention also provides a computer-readable storage medium having a computer program stored thereon, which implements the steps of any of the aforementioned methods for automatically opening and closing a charging cover when the computer program is executed by a processor.

[0096] Among them, the specific implementation methods and technical effects of the automatic opening and closing system of the charging cover, the automatic opening and closing device of the charging cover, and the computer-readable storage medium can all be referred to the embodiments of the automatic opening and closing method of the charging cover provided by the above-mentioned present invention, and will not be repeated here.

[0097] Those skilled in the art will further appreciate that the various illustrative logic blocks, modules, circuits, and algorithmic steps described in conjunction with the embodiments disclosed herein can be implemented as electronic hardware, computer software, or a combination of the two.
