Description

Technical Field

[0001] This invention relates to the field of AC charging control technology for new energy electric vehicles, specifically a method for controlling an electronic lock during AC charging of new energy vehicles. Background Technology

[0002] With technological advancements, automobiles are becoming increasingly diversified in terms of energy sources, and new energy vehicles such as hybrid vehicles and pure electric vehicles have now emerged.

[0003] The national standards for AC charging stipulate that when a car is using AC charging, an electronic lock is required to ensure a safe connection between the AC charging gun and the AC charging socket. In the current technology, the car must be unlocked through the central control screen or a specific button when charging. This control scheme is not only cumbersome, but also lacks the advantages of scheduled locking, setting locking time, and remote control. Summary of the Invention

[0004] The purpose of this invention is to provide a control method for the electronic lock of AC charging for new energy vehicles, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A method for controlling an AC charging electronic lock for a new energy vehicle includes: an AC charging dock, an on-board charger (OBC), a body control module (BCM), a remote key, an on-board T-BOX, a vehicle control system, an audio-visual entertainment system, a mobile app, and a back-end control system, comprising the following steps:

[0007] Step 1: When the owner approaches the vehicle with the remote key within the vehicle's control range, the Body Control Module (BCM) detects the radio wave signal. The BCM then communicates with the On-Board Charger (OBC) via the vehicle's T-BOX. The OBC sends a high-level signal to the AC charging dock via a hard-wired signal, unlocking the electronic lock. When the owner moves away from the vehicle with the remote key and is outside the vehicle's control range, the BCM no longer detects the radio wave signal emitted by the remote key. The BCM then communicates with the OBC via the vehicle's T-BOX, and the OBC sends a high-level signal to the AC charging dock via a hard-wired signal, locking the electronic lock.

[0008] Step 2: When the car owner sets the charging lock-up time, automatic locking during charging, and automatic unlocking during charging through the audio-visual entertainment system, the audio-visual entertainment system transmits the signal to the vehicle control system through the CAN network. The vehicle control system then transmits the signal to the on-board charger (OBC) through the CAN network. The OBC uses hard-wired high and low level control to control the AC charging socket to achieve the functions of charging lock-up time, automatic locking during charging, and automatic unlocking during charging.

[0009] Step 3: The car owner sets up scheduled locking, charging lock time, and remote unlocking and locking via a mobile app. The mobile app transmits this signal to the backend system via 5G, and the backend system transmits this signal to the vehicle T-BOX via 5G. The vehicle T-BOX and the vehicle control system transmit signals via CAN network. The vehicle control system and the on-board charger (OBC) transmit signals via CAN communication. The OBC uses hard-wired high and low voltage levels to control the AC charging socket to achieve scheduled locking, charging lock time setting, and remote unlocking and locking functions. After the OBC detects the electronic lock locking and unlocking, it transmits this signal to the vehicle control system via CAN network. The vehicle control system transmits this signal to the vehicle T-BOX via CAN network, and the vehicle T-BOX transmits this signal to the backend system via 5G network. The backend system then transmits this signal to the mobile app via 5G network. At this point, the mobile app displays the electronic lock's locking status.

[0010] As a further aspect of the present invention: in step two, the audio-visual entertainment system can realize scheduled locking and setting of charging lock-up time.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] This invention interacts with the vehicle's Body Control Module (BCM) via radio waves when the remote key approaches or moves away from the car. Simultaneously, the BCM and the On-Board Charger (OBC) communicate via a CAN network to control the electronic lock's locking and unlocking. This achieves automatic unlocking when the owner approaches and automatic locking when the owner moves away, eliminating the need for frequent button presses to unlock the electronic lock. Furthermore, the reduced need for frequent opening and closing extends the electronic lock's lifespan. The invention also allows the owner to control the locking time by setting a timer on the infotainment system. Additionally, the invention facilitates interaction between a mobile app and the vehicle's T-BOX via 4G signals. The T-BOX communicates with the vehicle control system via a CAN network, and the vehicle control system communicates with the OBC via a CAN network. The OBC then controls the electronic lock's locking and unlocking, enabling the owner to remotely control the electronic lock via a mobile app. Attached Figure Description

Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0015] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0016] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application. Example

[0017] Please see Figure 1 A method for controlling an AC charging electronic lock for a new energy vehicle includes: an AC charging dock, an on-board charger (OBC), a body control module (BCM), a remote key, an on-board T-BOX, a vehicle control system, an audio-visual entertainment system, a mobile app, and a back-end control system, comprising the following steps:

[0018] Step 1: When the owner approaches the vehicle with the remote key within the vehicle's control range, the Body Control Module (BCM) detects the radio wave signal. The BCM then communicates with the On-Board Charger (OBC) via the vehicle's T-BOX. The OBC sends a high-level signal to the AC charging dock via a hard-wired signal, unlocking the electronic lock. When the owner moves away from the vehicle with the remote key and is outside the vehicle's control range, the BCM no longer detects the radio wave signal emitted by the remote key. The BCM then communicates with the OBC via the vehicle's T-BOX, and the OBC sends a high-level signal to the AC charging dock via a hard-wired signal, locking the electronic lock.

[0019] Step 2: When the car owner sets the charging lock-up time, automatic locking during charging, and automatic unlocking during charging through the audio-visual entertainment system, the audio-visual entertainment system transmits the signal to the vehicle control system through the CAN network. The vehicle control system then transmits the signal to the on-board charger (OBC) through the CAN network. The OBC uses hard-wired high and low level control to control the AC charging socket to achieve the functions of charging lock-up time, automatic locking during charging, and automatic unlocking during charging.

[0020] Step 3: The car owner sets up scheduled locking, charging lock time, and remote unlocking and locking via a mobile app. The mobile app transmits this signal to the backend system via 5G, and the backend system transmits this signal to the vehicle T-BOX via 5G. The vehicle T-BOX and the vehicle control system transmit signals via CAN network. The vehicle control system and the on-board charger (OBC) transmit signals via CAN communication. The OBC uses hard-wired high and low voltage levels to control the AC charging socket to achieve scheduled locking, charging lock time setting, and remote unlocking and locking functions. After the OBC detects the electronic lock locking and unlocking, it transmits this signal to the vehicle control system via CAN network. The vehicle control system transmits this signal to the vehicle T-BOX via CAN network, and the vehicle T-BOX transmits this signal to the backend system via 5G network. The backend system then transmits this signal to the mobile app via 5G network. At this point, the mobile app displays the electronic lock's locking status.

[0021] It should be noted that the electronic lock automatically unlocks when the owner approaches the vehicle, eliminating the need for frequent button unlocking each time the charging gun is removed. This feature makes the electronic lock less prone to damage and extends its lifespan. Furthermore, the owner can control the unlocking and locking during charging through the audio-visual entertainment system, and remotely unlock and lock through the vehicle networking system. The owner can remotely control the charging and unlocking process and view the unlocking and locking status of the electronic lock via a mobile app. Example

[0022] Please see Figure 1 A method for controlling an AC charging electronic lock for a new energy vehicle includes: an AC charging dock, an on-board charger (OBC), a body control module (BCM), a remote key, an on-board T-BOX, a vehicle control system, an audio-visual entertainment system, a mobile app, and a back-end control system, comprising the following steps:

[0023] Step 1: When the owner approaches the vehicle with the remote key within the vehicle's control range, the Body Control Module (BCM) detects the radio wave signal. The BCM then communicates with the On-Board Charger (OBC) via the vehicle's T-BOX. The OBC sends a high-level signal to the AC charging dock via a hard-wired signal, unlocking the electronic lock. When the owner moves away from the vehicle with the remote key and is outside the vehicle's control range, the BCM no longer detects the radio wave signal emitted by the remote key. The BCM then communicates with the OBC via the vehicle's T-BOX, and the OBC sends a high-level signal to the AC charging dock via a hard-wired signal, locking the electronic lock.

[0024] Step 2: When the car owner sets the charging lock-up time, automatic locking during charging, and automatic unlocking during charging through the audio-visual entertainment system, the audio-visual entertainment system transmits the signal to the vehicle control system through the CAN network. The vehicle control system then transmits the signal to the on-board charger (OBC) through the CAN network. The OBC uses hard-wired high and low level control to control the AC charging socket to achieve the functions of charging lock-up time, automatic locking during charging, and automatic unlocking during charging.

[0025] Step 3: The car owner sets up scheduled locking, charging lock time, and remote unlocking and locking via a mobile app. The mobile app transmits this signal to the backend system via 5G, and the backend system transmits this signal to the vehicle T-BOX via 5G. The vehicle T-BOX and the vehicle control system transmit signals via CAN network. The vehicle control system and the on-board charger (OBC) transmit signals via CAN communication. The OBC uses hard-wired high and low voltage levels to control the AC charging socket to achieve scheduled locking, charging lock time setting, and remote unlocking and locking functions. After the OBC detects the electronic lock locking and unlocking, it transmits this signal to the vehicle control system via CAN network. The vehicle control system transmits this signal to the vehicle T-BOX via CAN network, and the vehicle T-BOX transmits this signal to the backend system via 5G network. The backend system then transmits this signal to the mobile app via 5G network. At this point, the mobile app displays the electronic lock's locking status.

[0026] Preferably, in this embodiment, in step two, the audio-visual entertainment system can perform scheduled locking and set charging lock-up time.

[0027] It should be noted that the audio-visual entertainment system can not only control unlocking and locking during charging, but also allows for scheduled locking and setting of lockout time.

[0028] It is important to note that this invention interacts with the vehicle's Body Control Module (BCM) via radio waves when the remote key approaches or moves away from the car. Simultaneously, the BCM and the On-Board Charger (OBC) communicate via a CAN network to control the electronic lock's locking and unlocking. This achieves the goal of automatically unlocking when the owner approaches and automatically locking when the owner moves away, eliminating the need for frequent button presses to unlock the electronic lock. Furthermore, the reduced need for frequent opening and closing extends the electronic lock's lifespan. The invention also allows the owner to control the locking time by setting a timer for the electronic lock on the infotainment system. Additionally, the mobile app interacts with the vehicle's T-BOX via 4G signals. The T-BOX communicates with the vehicle control system via a CAN network, and the vehicle control system communicates with the OBC via a CAN network. The OBC controls the electronic lock's locking and unlocking, enabling the owner to remotely control the electronic lock via a mobile app.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
