[0042] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0043] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0044] Figure 1 This is a flowchart illustrating a method for controlling a vehicle's charging port cover, as provided in an embodiment of this disclosure. The method can be applied to application scenarios requiring control of the vehicle's charging port cover. It can be executed by the vehicle charging port cover control device provided in this embodiment, which can be implemented using software and / or hardware. Figure 1 As shown, the vehicle's charging port cover control method includes:

[0045] S101. Obtain the working status of the charging gun, including the charging idle status.

[0046] Specifically, the charging gun is used to send control signals to the vehicle. For example, the control signal can be a radio frequency (RF) signal to control the opening of the charging port cover. The charging gun may contain a signal transmitting module, such as an RF transmitting module, and the vehicle may contain a signal receiving module. The signal transmitting module in the charging gun sends the control signal, such as the RF signal, to the vehicle, and the signal receiving module in the vehicle, such as the RF receiving module, controls the charging port cover to open automatically upon receiving the RF signal. For example, the charging gun may have a trigger component, such as a push-button switch. The user can trigger the RF transmitting module in the charging gun to send an RF signal to the vehicle by pressing the trigger component, and the RF transmitting module in the charging gun will stop sending RF signals to the vehicle when the user stops pressing the trigger component.

[0047] Furthermore, compared to integrating the RF transmitter module into other devices, such as the charging station, embedding the RF transmitter module within the charging gun shortens the transmission distance of the RF signal, i.e., the distance for wireless connection with the vehicle. This improves the stability of the RF signal transmission and increases the success rate of opening the charging port cover using the RF signal. Additionally, triggering the charging port cover using the RF signal is faster than triggering it using Bluetooth.

[0048] Optionally, the working status of the charging gun can be obtained by acquiring the working status flag signal of the charging gun and determining the working status of the charging gun based on the voltage value of the working status flag signal.

[0049] S102. When the charging gun is in an idle charging state, control the charging gun to send a control signal to the vehicle according to the external trigger command to open the charging port cover.

[0050] For example, when it is determined that the charging gun is in an idle charging state, the control gun sends a control signal, such as a radio frequency signal, to the vehicle according to an external trigger command. Specifically, Figure 3 In the signal 's', the 's' represents the on / off status signal of the trigger component on the charging gun. A high level 's' indicates that the trigger component is pressed, and a low level 's' indicates that the trigger component is not pressed. Figure 3 In this context, RF represents the radio frequency (RF) transmission status signal. Setting RF to a high level indicates that a control signal, such as an RF signal, is being transmitted. Setting RF to a low level indicates that the RF signal is idle, meaning that no control signal is being transmitted, such as an RF signal.

[0051] Therefore, the charging port cover control method provided in this embodiment first acquires the working state of the charging gun, including a charging idle state. When the charging gun is in the charging idle state, it controls the charging gun to send a control signal to the vehicle according to an external trigger command to open the charging port cover. Through the coordination of the working state and the external trigger command, the charging port cover can be automatically opened to charge the vehicle without any operation on the vehicle side, improving the user's charging experience and enhancing the intelligence of the charging process.

[0052] In addition, in some specific implementations, the control signal is a radio frequency (RF) signal. The system is set to acquire the working status of the charging gun and control whether the charging gun sends an RF signal to the vehicle to open the charging port cover based on the working status of the charging gun. This allows the system to adjust when to send an RF signal to the vehicle to control the opening of the charging port cover, rather than allowing the user to open the charging port cover at any time by operating the charging gun. This improves the accuracy of the RF signal control process for opening the charging port cover and avoids user misoperation of opening the charging port cover.

[0053] Figure 2 This is a schematic diagram of a vehicle charging port cover control system provided in an embodiment of this disclosure. Figure 2 As shown, the charging gun 1 includes a working status flag port CP. The working status flag port CP is used to output a working status flag signal. The working status of the charging gun 1 can be determined according to the voltage value of the working status flag signal. The working status of the charging gun 1 includes the charging gun 1 being in the charging idle state, that is, the state of the charging gun 1 when the vehicle is not being charged. At this time, the charging gun 1 is generally placed on the charging pile. The working status of the charging gun 1 also includes the charging gun 1 being connected to the vehicle's charging port. At this time, the charging gun 1 has been inserted into the vehicle's charging port. The working status of the charging gun 1 also includes the charging gun 1 being unplugged from the vehicle's charging port, that is, the charging gun 1 is unplugged from the vehicle's charging port after the vehicle is fully charged.

[0054] Optionally, the working state of the charging gun can be determined based on the voltage value of the working state indicator signal. Specifically, when the voltage value of the working state indicator signal maintains a first voltage, the charging gun is determined to be in a first state, which is a charging idle state; when the voltage value of the working state indicator signal changes from the first voltage to a second voltage, the charging gun is determined to be in a second state, which is a state where the charging gun is successfully connected to the vehicle's charging port; and when the voltage value of the working state indicator signal changes from the second voltage to the first voltage, the charging gun is determined to be in a third state, which is a state where the charging gun is disconnected from the vehicle's charging port. The first voltage is different from the second voltage.

[0055] For example, the first voltage can be 12V and the second voltage can be 9V. Of course, 12V and 9V are not limitations on the first and second voltages. The specific values ​​of the first and second voltages can be set according to the actual charging needs of the vehicle.

[0056] Figure 3 The diagram shows the waveforms of parameters involved in a vehicle charging port cover control method provided in this embodiment of the disclosure. Figure 3 The CP port in the middle represents the working status flag signal output by the charging gun. The working status of the charging gun can be divided into three stages: T0 to T1, the charging gun is in an idle charging state; T1 to T2, the charging gun is connected to the vehicle's charging port; T2 to T3, the charging gun is unplugged from the vehicle's charging port. Figure 3As can be seen, during the T0 to T1 period, the voltage value of the working status indicator signal cp remains at the first voltage, for example, 12V. From the T0 to T1 period to the T1 to T2 period, the voltage value of the working status indicator signal cp changes from the first voltage to the second voltage, for example, from 12V to 9V. From the T1 to T2 period to the T2 to T3 period, the voltage value of the working status indicator signal cp changes from the second voltage to the first voltage, for example, from 9V to 12V. Therefore, when the voltage value of the working status indicator signal cp remains at the first voltage, it can be determined that the charging gun is in an idle charging state; when the voltage value of the working status indicator signal cp changes from the first voltage to the second voltage, it can be determined that the charging gun is successfully connected to the vehicle's charging port; when the voltage value of the working status indicator signal cp changes from the second voltage to the first voltage, it can be determined that the charging gun has been unplugged from the vehicle's charging port.

[0057] like Figure 3 As shown, when the charging gun is in an idle charging state, i.e., during the T0 to T1 period, the charging gun controls the sending of control signals, such as radio frequency signals, to the vehicle based on external trigger commands. Specifically, when the user presses the trigger component on the charging gun, the charging gun sends a control signal, such as a radio frequency signal, to the vehicle; when the user does not press the trigger component, the charging gun does not send any control signals, such as radio frequency signals, and this is reflected in the charging output. Figure 3 That is, during the time period from T0 to T1, the waveforms of the switch state signal s and the radio frequency transmission state signal rf are consistent, i.e. Figure 3 It can be characterized that during the period from T0 to T1, when the user presses the trigger component on the charging gun, the switch state signal s is at a high level, and the charging gun sends a control signal to the vehicle, such as a radio frequency signal, i.e., the radio frequency transmission state signal rf is at a high level; when the user does not press the trigger component on the charging gun, the switch state signal s is at a low level, and the charging gun does not send a control signal, such as a radio frequency signal, i.e., the radio frequency transmission state signal rf is at a low level.

[0058] Therefore, when the charging gun is determined to be in an idle charging state, the control unit sends a control signal, such as a radio frequency (RF) signal, to the vehicle based on an external trigger command. Each press of the trigger component on the charging gun sends a control signal, such as an RF signal, to the vehicle; the duration of the press is the duration of the RF transmission. During the idle charging state, the charging port cover automatically opens to charge the vehicle without any on-vehicle operation, improving the user's charging experience and enhancing the intelligence of the charging process. Optionally, when the charging gun is in the second state, the control unit stops sending control signals; that is, when the connection between the charging gun and the vehicle's charging port is determined to be complete, the control unit stops sending control signals, such as RF signals.

[0059] Specifically, once the charging gun is connected to the vehicle's charging port, operating during the T1 to T2 period, where T1 is the moment the charging gun is plugged in and T1 to T2 is the period during which the connection between the charging gun and the vehicle's charging port is complete, the charging gun stops sending control signals, such as radio frequency signals. Even if the user presses the trigger component on the charging gun, it will no longer send radio frequency signals to the vehicle. Figure 3 In other words, during the period from T1 to T2, regardless of whether the user presses the trigger component on the charging gun, or whether the switch status signal s is high, the charging gun will no longer send control signals, such as radio frequency signals, to the vehicle; that is, the radio frequency transmission status signal rf will remain low. Therefore, once the connection between the charging gun and the vehicle's charging port is determined to be complete, the charging gun will not send a radio frequency signal to the vehicle to control the opening of the charging port cover, no matter how the user presses the trigger component, because the charging port cover is already open during this stage, thus preventing accidental opening of the charging port cover by the user during this period.

[0060] Optionally, when the charging gun is in the third operating state, the charging gun is controlled to stop sending control signals. That is, when it is determined that the charging gun has been unplugged from the vehicle's charging port, the charging gun is controlled to stop sending control signals, such as radio frequency signals. Specifically, the charging gun is unplugged from the vehicle's charging port, which means the charging gun is operating during the T2 to T3 period. T2 is the moment the charging gun is unplugged, and T3 can be the moment the charging port cover is closed and the latch on the charging port cover is locked. The T2 to T3 period is the time during which the charging gun is unplugged from the vehicle's charging port. During this period, the charging gun is controlled to stop sending control signals, such as radio frequency signals. At this time, even if the user presses the trigger component on the charging gun, the charging gun will no longer send radio frequency signals to the vehicle, which is reflected in the charging port. Figure 3 In other words, during the T2 to T3 period, regardless of whether the user presses the trigger component on the charging gun, or whether the switch status signal s is high, the charging gun will no longer send control signals, such as radio frequency signals, to the vehicle; that is, the radio frequency transmission status signal rf remains low. Therefore, once it is determined that the charging gun has been unplugged from the vehicle's charging port, the charging gun enters a radio frequency delay state. This means that no matter how the user presses the trigger component on the charging gun, the charging gun will not send a radio frequency signal to the vehicle to open the charging port cover, because charging is complete at this stage, and the necessary action should be to close the charging port cover. This embodiment of the present disclosure employs a radio frequency delay strategy in its software logic, which effectively prevents the user from accidentally opening the charging port cover again due to a mis-triggered radio frequency signal when hanging the charging gun, thus avoiding malfunctions when the charging gun is attached to the mounting bracket.

[0061] Optionally, before the charging gun sends a control signal to the vehicle according to an external trigger command, the vehicle's first identification information and control signal, such as the second identification information of the radio frequency signal, can be obtained. The matching degree between the first identification information and the second identification information can be used to control whether the charging gun sends a control signal to the vehicle, such as the radio frequency signal, according to the working state of the charging gun, i.e., control the transmission period of the radio frequency signal.

[0062] Optionally, if the first identification information matches the second identification information, then the subsequent step of controlling the charging gun to send a control signal to the vehicle according to an external trigger command is executed, that is, controlling whether the charging gun sends a control signal to the vehicle, such as a radio frequency signal, according to the working state of the charging gun, that is, controlling the transmission period of the radio frequency signal; if the first identification information does not match the second identification information, then the subsequent step of controlling the charging gun to send a control signal to the vehicle according to an external trigger command is not executed, that is, controlling the charging gun to stop sending control signals, such as radio frequency signals.

[0063] Specifically, the first identity information may include the vehicle owner's information, and the second identity information may include control signals, such as the ID of a radio frequency (RF) signal. The RF ID can be pre-bound to the vehicle owner's information via the cloud. Before controlling the vehicle's charging port cover, the first identity information and the control signals (e.g., the second identity information of the RF signal) are obtained, and it is determined whether the first and second identity information match. Only when the first and second identity information match will the RF signal transmission period be controlled according to the charging gun's operating status. If the first and second identity information do not match, the charging gun will stop sending control signals (e.g., RF signals) to prevent the charging port covers of multiple vehicles from being opened after the charging gun sends RF signals. Therefore, the binding logic of this embodiment adopts a cloud-based approach, which can automatically complete the binding of the charging gun's RF ID and the vehicle owner's information without user intervention.

[0064] For example, the vehicle in this disclosure embodiment can be a new energy vehicle, such as a plug-in hybrid electric vehicle, a range-extended electric vehicle, or a pure electric vehicle, etc., and this disclosure embodiment does not specifically limit it.

[0065] This embodiment first acquires the operating status of the charging gun, including a charging idle state. When the charging gun is in the charging idle state, it controls the charging gun to send a control signal to the vehicle according to an external trigger command to open the charging port cover. Through the coordination of the operating status and external trigger commands, the charging port cover can be automatically opened to charge the vehicle without any on-vehicle operation, improving the user's charging experience and enhancing the intelligence of the charging process. Furthermore, in some specific embodiments, the control signal is a radio frequency (RF) signal. By acquiring the charging gun's operating status and controlling the RF signal transmission period based on that status, the timing of sending the RF signal to the vehicle to control the charging port cover opening can be adjusted according to the charging gun's operating status. This prevents the user from opening the charging port cover at any time by operating the charging gun, improving the accuracy of the RF signal-controlled charging port cover opening process and avoiding accidental opening by the user.

[0066] It should be noted that the specific execution order of the above steps is not specifically limited in this embodiment. The steps can be executed simultaneously or sequentially according to the actual charging needs of the vehicle. Furthermore, the vehicle charging port cover control method described in the above embodiments can be executed by a controller in the vehicle, or by a charging pile or charging gun.

[0067] This disclosure also provides a vehicle charging port cover control device. Figure 4 This is a schematic diagram of a vehicle charging port cover control device provided in an embodiment of this disclosure. Figure 4 As shown, the vehicle's charging port cover control device includes a status acquisition module 201 and a control module 202. The status acquisition module 201 is used to acquire the working status of the charging gun, including a charging idle state. The control module 202 is used to control the charging gun to send a control signal to the vehicle according to an external trigger command when the charging gun is in the charging idle state, so as to open the charging port cover. For example, in conjunction with... Figure 2 and Figure 4 The status acquisition module 201 and the control module 202 can be integrated into the control device 2, for example, integrated into the main control board 3 of the control device 2, or set up independently of the main control board 3.

[0068] Optionally, the status acquisition module 201 is specifically used to acquire the working status flag signal of the charging gun and determine the working status of the charging gun based on the voltage value of the working status flag signal.

[0069] This embodiment first acquires the working status of the charging gun, including a charging idle state. When the charging gun is in the charging idle state, it controls the charging gun to send a control signal to the vehicle according to an external trigger command to open the charging port cover. Through the coordination of the working status and external trigger commands, the charging port cover can be automatically opened to charge the vehicle without any operation on the vehicle side, improving the user's charging experience and enhancing the intelligence of the process of opening the charging port cover to charge the vehicle.

[0070] This disclosure also provides a vehicle charging port cover control system, such as... Figure 2 As shown, the vehicle's charging port cover control system includes a charging gun 1 and a control device 2. The control device 2 is communicatively connected to the charging gun 1, meaning they can be connected via wired or wireless means. The charging gun 1 includes a signal transmitting module 5, which sends control signals, such as radio frequency signals, to the vehicle to control the opening of the charging port cover. This allows the charging port cover to open automatically without user intervention, improving the user's charging experience and enhancing the intelligence of the charging process. Furthermore, compared to integrating the signal transmitting module 5 into other devices, such as the charging station, embedding it within the charging gun 1 shortens the transmission distance of the control signal, such as the radio frequency signal, thus reducing the distance for wireless connection with the vehicle. This improves the stability of the control signal, such as the radio frequency signal, and increases the success rate of opening the charging port cover using the radio frequency signal. Additionally, triggering the opening of the charging port cover using a radio frequency signal is faster than triggering it using a Bluetooth signal.

[0071] The control device 2 is used to execute the vehicle charging port cover control method as described in the above embodiment. Specifically, the control device 2 acquires the operating state of the charging gun 1 and controls the charging gun to send a radio frequency (RF) signal to the vehicle to open the charging port cover based on the operating state of the charging gun 1. Specifically, when the control device 2 determines that the charging gun 1 is in a charging idle state, it controls the charging gun 1 to send a control signal, such as an RF signal, to the vehicle according to an external trigger command. When the control device 2 determines that the connection between the charging gun 1 and the vehicle's charging port is complete, it controls the charging gun 1 to stop sending control signals, such as RF signals. When the control device 2 determines that the charging gun 1 is unplugged from the vehicle's charging port, it controls the charging gun 1 to stop sending control signals, such as RF signals. Therefore, the timing of sending control signals, such as RF signals, to the vehicle to control the opening of the charging port cover can be adjusted according to the operating state of the charging gun 1, rather than allowing the user to open the charging port cover at any time by operating the charging gun 1. This improves the accuracy of the RF signal-controlled charging port cover opening process and avoids user misoperation of opening the charging port cover.

[0072] Optionally, the control device 2 can be integrated into the vehicle or the charging pile. That is, the control device 2 can be integrated into the vehicle. For example, the control device 2 can be a controller within the vehicle. Exemplarily, the controller in the vehicle can be a VCU (Vehicle Control Unit). This embodiment does not specifically limit the type of controller. The control device 2 in the vehicle can obtain the operating status of the charging gun 1. In this case, the radio frequency receiving module can be integrated into the control device 2, for example, it can be integrated into the main control board 3, or it can be set independently of the main control board 3. Alternatively, the control device 2 can be integrated into the charging pile, and the charging pile can obtain the operating status of the charging gun 1.

[0073] Optionally, such as Figure 2 As shown, the charging gun 1 may also include a triggering component K1, and the signal transmitting module 5 is used to send an radio frequency signal to the vehicle according to the triggering state of the triggering component K1. Specifically, the triggering component K1, such as a push switch, may be disposed on the housing of the charging gun 1. The user can control the signal transmitting module 5 to send an radio frequency signal to the vehicle by pressing the triggering component K1 on the charging gun 1, such as the push switch, to control the opening of the vehicle's charging port cover.

[0074] Optionally, the signal transmitting module 5 can be an radio frequency transmitting module, and the control device 2 can include a switching circuit. Figure 2 The switching circuit is not shown. The control device 2 may include a main control board 3, and the switching circuit is integrated within the main control board 3. The switching circuit is connected in series between the RF power supply 4 and the signal transmission module 5, such as the RF transmission module. The control device 2 is used to control the conduction period of the switching circuit according to the working state of the charging gun 1. Specifically, the control device 2 obtains the working state of the charging gun 1. When the control device 2 determines that the charging gun 1 is in a charging idle state, the main control board 3 in the control device 2 controls the switching circuit to conduct, that is, controls the RF power supply 4 to connect with the signal transmission module 5, such as the RF transmission module. The RF power supply 4 can provide a power supply voltage of, for example, 12V. At this time, the user presses the trigger component K1 on the charging gun 1, such as pressing a switch. The trigger component K1 is electrically connected to the signal transmission module 5, such as the RF transmission module, so that the RF power supply 4 forms a loop to the ground terminal PE through the signal transmission module 5, such as the RF transmission module. The signal transmission module 5, such as the RF transmission module, is energized and then sends an RF signal to the vehicle according to the user's pressing action.

[0075] When the control device 2 determines that the charging gun 1 is successfully connected to the vehicle's charging port or that the charging gun 1 has been unplugged from the vehicle's charging port, the main control board 3 in the control device 2 shuts off the control switch circuit, that is, it disconnects the connection line from the RF power supply 4 to the signal transmission module 5, for example, the RF transmission module. At this time, even if the user presses the trigger component K1 on the charging gun 1, for example, by pressing a switch, the signal transmission module 5, for example, the RF transmission module, has no power source and cannot send RF signals. Therefore, once the control device 2 determines that the charging gun 1 is successfully connected to the vehicle's charging port or that the charging gun 1 has been unplugged from the vehicle's charging port, it controls the charging gun 1 to enter the RF delay state. That is, no matter how the user presses the trigger component K1 on the charging gun 1, for example, by pressing a switch, the charging gun 1 will not send an RF signal to the vehicle to open the charging port cover, effectively preventing the user from accidentally triggering the RF signal and opening the charging port cover again.

[0076] Optionally, such as Figure 2 As shown, the charging gun 1 may also include an unlocking control circuit. The unlocking control circuit sends an unlocking trigger signal to the vehicle's controller to control the vehicle's charging port to unlock from the charging gun 1. The unlocking control circuit is used to send an unlocking trigger signal to the vehicle's controller according to the triggering state of the triggering component K1, thereby controlling the vehicle's charging port to unlock from the charging gun 1.

[0077] Optionally, the unlocking control circuit may include a first path, a second path, and an unlocking controller 7. The triggering component K1 triggers the unlocking control circuit to select the first path or the second path to connect to the unlocking controller 7. The first path, as a valid path, corresponds to the vehicle's charging port being locked with the charging gun 1, and the second path, as a valid path, corresponds to the vehicle's charging port being unlocked with the charging gun 1. The equivalent resistance of the first path is different from that of the second path.

[0078] For example, such as Figure 2As shown, a first path can be configured including a first impedance element R1, and a second path can include a first impedance element R1 and a second impedance element R2. The triggering component K1 can be, for example, a single-pole double-throw switch. When it is necessary to unplug the charging gun 1 from the vehicle's charging port, pressing the triggering component K1 on the charging gun 1 connects the RF transmitting module to the ground terminal PE. The control device 2 can control the RF transmitting module not to transmit RF signals by disconnecting the internal switching circuit. At this time, the first impedance element R1 and the second impedance element R2 are connected in series to the ground terminal PE and the unlocking controller 7. When the unlocking controller 7 detects that the first impedance element R1 and the second impedance element R2 are connected, it controls the vehicle's charging port and the charging gun 1 to automatically unlock, so that the charging gun 1 can be unplugged from the vehicle's charging port. That is, the unlocking controller 7 is used to control the vehicle and the charging gun 1 to unlock when the second path is connected. Thus, in this embodiment of the present disclosure, the unlocking of the vehicle's charging port and the charging gun 1 can be automatically completed by pressing the triggering component K1, simplifying the operation process of unplugging the charging gun 1 from the vehicle's charging port.

[0079] In addition, such as Figure 2 As shown, when the charging gun 1 is connected to the vehicle's charging port, the trigger component K1 on the charging gun 1 is no longer pressed. At this time, the second impedance element R2 is short-circuited by the trigger component K1, and only the first impedance element R1 is connected to the ground terminal PE and the unlocking controller 7. When the unlocking controller 7 detects that only the first impedance element R1 is connected, it controls the vehicle's charging port and the charging gun 1 to automatically lock together. That is, the unlocking controller 7 is used to control the vehicle and the charging gun 1 to lock together when the first channel is connected, so that the charging gun 1 and the vehicle's charging port are automatically locked together when the connection is completed, thereby improving the connection stability between the charging gun 1 and the vehicle's charging port during charging.

[0080] Alternatively, the first impedance element R1 and the second impedance element R2 can be connected in series to the grounding terminal PE and the unlocking controller 7. Compared with only the first impedance element R1 being connected to the grounding terminal PE and the unlocking controller 7, the voltage of the electrical signal monitored by the unlocking controller 7 is different. The unlocking controller 7 can determine whether the first impedance element R1 and the second impedance element R2 are connected in series or only the first impedance element R1 is connected based on the voltage of the monitored electrical signal.

[0081] Therefore, this embodiment of the present disclosure utilizes the same triggering component K1 in the charging gun 1 to control the control signals in the charging gun 1, such as the transmission of radio frequency signals, and the unlocking of the vehicle charging port and the charging gun 1. By sending radio frequency signals from the charging gun 1 to the vehicle to control the opening of the charging port cover, the charging port cover can be automatically opened to charge the vehicle without any operation on the vehicle side. This improves the user's charging experience, enhances the intelligence of the process of opening the charging port cover to charge the vehicle, and automatically unlocks the vehicle's charging port and the charging gun 1 by pressing the triggering component K1. This simplifies the process of unplugging the charging gun 1 from the vehicle's charging port, simplifies the implementation structure of using control signals, such as radio frequency signals, to open the charging port cover and unlock the vehicle's charging port and the charging gun 1, and reduces the implementation cost of using radio frequency signals to open the charging port cover and unlock the vehicle's charging port and the charging gun 1.
