Description
Technical Field
[0001] This invention relates to the field of electric vehicle charging technology, specifically to a charging control system and method based on Bluetooth Low Energy technology. Background Technology
[0002] With the increasing number of electric vehicles, public charging stations are no longer sufficient to meet user demand. More electric vehicle users are installing private charging stations in their parking spaces. However, since parking garages in residential communities are mostly public areas, authorization is required to prevent unauthorized use of charging stations. Currently, the mainstream charging station activation methods are card swiping or mobile app control. Card swiping has the problem of easily lost charging cards, while mobile app control is limited by the network signal in the parking garage. Existing Bluetooth-based charging control methods have problems such as unoptimized control logic to identify user charging intentions in advance, slow Bluetooth authorization and charging response speeds, increased vehicle power consumption due to prolonged Bluetooth operation, insufficient security, and the risk of battery theft. Furthermore, existing technologies also have drawbacks such as limited connectivity in scenarios with multiple vehicles bound by the master-slave relationship between the charging station and the vehicle, the need for manual operation, and complex authentication. Summary of the Invention
[0003] The purpose of this invention is to provide a charging control system and method based on Bluetooth Low Energy technology. This invention achieves fast, safe, and low-power electric vehicle charging control without human intervention.
[0004] To achieve this objective, the present invention provides a charging control system based on Bluetooth Low Energy technology, comprising: The list acquisition module is used to obtain vehicle information that is bound to the target charging station, thereby obtaining a list of legitimate target vehicles; The identity authentication module is used to initiate a Bluetooth connection request to all legitimate target vehicles in the list of legitimate target vehicles after the charging gun of the target charging pile is inserted into the charging interface of the current vehicle and the insertion event is triggered. It also establishes a Bluetooth communication connection with the legitimate target vehicles that respond to the Bluetooth connection request and performs interactive authentication of the legitimate target vehicles through the Bluetooth communication connection. After the interactive authentication is successful, the charging control module is used to detect whether the charging interface of the legitimate target vehicle is connected to the charging gun through the established Bluetooth communication connection, and to detect whether the charging gun of the target charging pile is connected to the charging interface of the vehicle. If the charging interface of the legitimate target vehicle is connected to the charging gun, and the charging gun of the target charging pile is connected to the charging interface of the vehicle, then the status is determined to be matched, and the target charging pile starts charging the current vehicle.
[0005] The preferred method for obtaining the list of legitimate target vehicles is as follows: Based on the preset binding relationship between charging piles and vehicles, the charging piles compare the format of all vehicle Bluetooth device names obtained by scanning Bluetooth broadcasts with the preset format of bound vehicle Bluetooth device names to filter out all candidate vehicles. Then, the MAC addresses of all candidate vehicles are compared with the preset database of bound legal Bluetooth MAC addresses to obtain a list of legal target vehicles.
[0006] Preferably, the charging gun is inserted into the charging interface of the target vehicle, and the insertion event is triggered based on the handshake signal between the charging pile and the target vehicle. The handshake signal includes a CC signal and a CP signal, wherein the CC signal is a connection confirmation signal; and the CP signal is a control pilot signal used to transmit charging control commands.
[0007] Preferably, the specific process by which the charging pile initiates Bluetooth connection requests to all legitimate target vehicles in the list of legitimate target vehicles and establishes Bluetooth communication connections with the legitimate target vehicles that respond to the Bluetooth connection requests is as follows: The connection level of each legitimate target vehicle is calculated based on the historical connection frequency and timestamp of all legitimate target vehicles, and all legitimate target vehicles are prioritized. After the charging gun is inserted into the charging port of the target vehicle and triggers the insertion event, the charging pile initiates Bluetooth connection requests to the legitimate target vehicles in descending order of connection level.
[0008] Preferably, the specific process of interactive authentication of the legitimate target vehicle via Bluetooth communication connection is as follows: During interactive authentication, the charging pile sends a random number to the legitimate target vehicle. The legitimate target vehicle uses a pre-shared key to encrypt the random number to generate a response value. The charging pile verifies the response value. If the verification is successful, the interactive authentication is completed.
[0009] Preferably, the specific method for detecting whether the charging port of a legitimate target vehicle is connected to the charging gun is as follows: After establishing a Bluetooth communication connection, the system monitors the connection confirmation signal and control pilot signal of the charging interface of the legitimate target vehicle in real time. When a valid signal level change is detected, the controller on the vehicle end generates a status command indicating that the interface is connected and sends the status command indicating that the interface is connected to the target charging pile through the established Bluetooth communication link.
[0010] Preferably, the specific method for detecting whether the charging gun of the target charging station is connected to the vehicle's charging interface is as follows: The target charging pile uses an electrical sensor inside the charging gun connector to collect the voltage parameters at the contact point between the charging gun and the vehicle's charging interface in real time. When the voltage parameters meet the preset connection threshold range, the controller of the target charging pile determines that the charging gun and the vehicle's charging interface are connected and generates a corresponding electrical connection confirmation signal.
[0011] Preferably, after the charging gun is inserted into the charging port of the target vehicle and triggers the insertion event, the charging pile initiates a Bluetooth connection request to all legitimate target vehicles in the list of legitimate target vehicles, and establishes a Bluetooth communication connection with the legitimate target vehicle that responds to the Bluetooth connection request. The legitimate target vehicle is then interactively authenticated through the Bluetooth communication connection. If the interactive authentication fails, the Bluetooth connection between the charging pile and the legitimate target vehicle is disconnected.
[0012] A charging control method based on Bluetooth Low Energy technology includes the following steps: Obtain vehicle information that is associated with the target charging station to obtain a list of legitimate target vehicles; After the charging gun of the target charging station is inserted into the charging interface of the current vehicle and the insertion event is triggered, a Bluetooth connection request is initiated to all legitimate target vehicles in the list of legitimate target vehicles, and a Bluetooth communication connection is established with the legitimate target vehicles that respond to the Bluetooth connection request. The legitimate target vehicles are then interactively authenticated through the Bluetooth communication connection. After the interactive authentication is successful, the system detects whether the charging port of the legitimate target vehicle is connected to the charging gun through the established Bluetooth communication connection, and detects whether the charging gun of the target charging pile is connected to the charging port of the vehicle. If the charging port of the legitimate target vehicle is connected to the charging gun, and the charging gun of the target charging pile is connected to the charging port of the vehicle, the status is determined to be matched, and the target charging pile starts charging the current vehicle.
[0013] A computer program product includes a computer program that, when executed by a processor, implements the steps of the above-described method.
[0014] The beneficial effects of this invention are: This invention employs Bluetooth Low Energy technology, combined with the synergistic effects of list acquisition, identity authentication, and charging control, along with a clear screening, triggering, authentication, and detection process. After a legitimate target vehicle is bound to a target charging station, the user does not need to swipe a card or set up a mobile app; simply inserting the charging gun triggers Bluetooth communication connection, interactive authentication, and bidirectional electrical connection detection. This improves the convenience of using charging stations and charging response speed, while reducing overall vehicle power consumption. Through multiple screening, encrypted authentication, and bidirectional electrical connection verification mechanisms, this invention effectively avoids the risk of electricity theft, solves the connection problem in multi-vehicle binding scenarios, and ensures the safety, reliability, and efficiency of the charging process. Attached Figure Description
[0015] Figure 1 This is a schematic diagram of the structure of the present invention; Figure 2 This is a flowchart of the present invention. Detailed Implementation
[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Example 1 A charging control system based on Bluetooth Low Energy technology, such as Figure 1 As shown, it includes: The list acquisition module is used to acquire vehicle information that is bound to the target charging pile (the target charging pile is a bound legal charging pile that has received legal target vehicle information), thereby obtaining a list of legal target vehicles. This design forms a list of legal target vehicles by acquiring vehicle information that is bound to the target charging pile, directly excluding unbound illegal vehicles from participating in the subsequent connection and authentication process, reducing invalid Bluetooth connection requests and authentication operations, narrowing the scope of vehicle identity verification, and effectively avoiding interference from irrelevant vehicles. The identity authentication module initiates Bluetooth connection requests to all legitimate target vehicles in the list of legitimate target vehicles after the charging gun of the target charging station is inserted into the charging interface of the current vehicle and triggers the insertion event. It then establishes a Bluetooth communication connection with the legitimate target vehicle that responds to the request. Interactive authentication is performed on the legitimate target vehicle via Bluetooth. If the authentication is successful, the responding vehicle is determined to be the currently authorized vehicle awaiting charging, and subsequent battery connection checks are initiated. If authentication fails, the Bluetooth connection is disconnected. This design initiates the Bluetooth connection request and performs interactive authentication only after the insertion event is triggered, and only operates on vehicles in the list of legitimate target vehicles, avoiding the risk of unauthorized vehicles attempting to steal electricity via Bluetooth connection. Interactive authentication via Bluetooth communication eliminates the need for users to swipe cards or configure mobile apps, improving the convenience of using the charging station and reducing user operational complexity. After successful interactive authentication, the charging control module detects whether the charging port of the legitimate target vehicle is connected to the charging gun via the established Bluetooth communication connection, and also detects whether the charging gun of the target charging pile is connected to the vehicle's charging port. If both the legitimate target vehicle's charging port and the target charging pile's charging gun are connected, the status is considered matched, and the target charging pile starts charging the current vehicle. This design simultaneously detects the connection status of the legitimate target vehicle's charging port and the charging gun, as well as the connection status of the target charging pile's charging gun and the vehicle's charging port. Charging is only initiated when both conditions are met and the statuses match, forming a two-way verification mechanism. This effectively avoids false connections and electricity theft that may occur when only one side is detected, improving the safety and reliability of the charging process.
[0017] The specific method for obtaining the list of legitimate target vehicles in the above technical solution is as follows: Based on the preset binding relationship between charging piles and vehicles, the charging pile compares the format of all vehicle Bluetooth device names obtained by scanning Bluetooth broadcasts with the preset format of bound vehicle Bluetooth device names to filter out all candidate vehicles. Then, the MAC addresses of all candidate vehicles are compared with the preset database of bound legitimate Bluetooth MAC addresses (the preset database of bound legitimate Bluetooth MAC addresses refers to a list of MAC addresses of pre-authorized bound vehicle Bluetooth devices stored inside the charging pile) to obtain a list of legitimate target vehicles. The above design uses the Bluetooth device name format for initial comparison to filter candidate vehicles, and then uses the MAC address to perform a second comparison with the preset database of bound legitimate Bluetooth MAC addresses. This dual filtering mechanism ensures that no legitimate vehicles are missed, while accurately excluding illegal vehicles that do not meet the criteria, avoiding situations where legitimate vehicles cannot pass or illegal vehicles are mixed in due to ambiguous filtering standards.
[0018] In the above technical solution, the charging gun is inserted into the charging interface of the target vehicle. The insertion event is triggered based on the handshake signal between the charging pile and the target vehicle. The handshake signal includes a CC signal and a CP signal. The CC signal is a connection confirmation signal used to confirm the physical connection status. The CP signal is a control pilot signal used to transmit charging control commands. In the above design, the CC signal as a connection confirmation signal can accurately determine the physical connection status between the charging gun and the vehicle charging interface. The CP signal as a control pilot signal can ensure the transmission of charging control commands. The combination of the two can improve the reliability of the insertion event triggering and avoid false start or failure to start in time due to inaccurate triggering signals.
[0019] In the above technical solution, the specific process by which the charging pile initiates Bluetooth connection requests to all legitimate target vehicles in the list of legitimate target vehicles and establishes a Bluetooth communication connection with the legitimate target vehicles that respond to the Bluetooth connection requests is as follows: The system trains on all legal target vehicles in the list of legal target vehicles and calculates the connection level of each legal target vehicle based on the historical connection frequency and timestamp of all legal target vehicles. Based on the connection frequency and most recent connection timestamp of each legitimate target vehicle within a preset time period (which can be set to 30 days), a weighted score is calculated for each legitimate target vehicle. The calculation formula is: S n = ɑF + βT; Among them, S n denoted as the weighted score of the nth legitimate target vehicle, α represents the weight coefficient of the connection frequency within a preset time period, F represents the normalized value of the connection frequency within a preset time period, β represents the weight coefficient of the most recent connection timestamp, and T represents the normalized value of the most recent connection timestamp. Based on the weighted score of each legitimate target vehicle, all legitimate target vehicles are prioritized from highest to lowest to obtain the connection level of each legitimate target vehicle. After the charging gun is inserted into the charging port of the target vehicle and triggers the insertion event, the charging pile initiates Bluetooth connection requests to the legitimate target vehicles according to their connection levels from high to low. The above design allows the charging pile to initiate Bluetooth connection requests according to the connection level from high to low, which can prioritize establishing connections with legitimate target vehicles with high usage frequency and recent connection records. This conforms to the actual usage habits of users and avoids resource competition and connection failure problems caused by indiscriminate connection initiation. In scenarios where the charging pile is bound to multiple vehicles and some vehicles are nearby, it can effectively solve the problem of connection failure caused by the connection limit and improve the efficiency and reliability of the connection.
[0020] In the above technical solution, the specific process of interactive authentication of the legitimate target vehicle via Bluetooth communication connection is as follows: During interactive authentication, the charging station sends a random number to the legitimate target vehicle. The legitimate target vehicle uses a pre-shared key to encrypt the random number and generate a response value. The charging station verifies the response value, and if the verification is successful, the interactive authentication is passed. In the above design, the encryption authentication mechanism of the pre-shared key has high security. The use of random numbers makes each authentication process unique, difficult to copy or crack, effectively preventing illegal vehicles from impersonating the Bluetooth information of legitimate target vehicles for authentication, and ensuring that only truly bound legitimate target vehicles can pass the authentication.
[0021] In the above technical solution, the specific method for detecting whether the charging port of a legitimate target vehicle is connected to the charging gun is as follows: After establishing a Bluetooth communication connection, the system monitors the connection confirmation signal and control pilot signal of the charging interface of the legitimate target vehicle in real time. When a valid signal level change is detected, the controller on the vehicle generates a status command indicating that the interface is connected and sends the status command to the target charging pile through the established Bluetooth communication link. This design, by monitoring the level changes of the CC and CP signals in real time, can accurately determine the actual connection status of the charging interface of the legitimate target vehicle. The generated status command is sent to the charging pile through the established Bluetooth communication connection, which can avoid status matching errors caused by inaccurate detection on the vehicle side or data transmission delay.
[0022] In the above technical solution, the specific method for detecting whether the charging gun of the target charging pile is connected to the vehicle's charging interface is as follows: The target charging pile uses an electrical sensor inside the charging gun connector to collect the voltage parameters at the contact point between the charging gun and the vehicle's charging interface in real time. When the voltage parameters meet the preset connection threshold range, the controller of the target charging pile determines that the charging gun and the vehicle's charging interface are connected and generates a corresponding electrical connection confirmation signal. This design, by collecting the voltage parameters at the contact point between the target charging gun and the vehicle's charging interface in real time using the electrical sensor of the target charging pile and using the preset connection threshold range as the judgment standard, can accurately determine the actual connection status of the target charging pile's charging gun. The generated electrical connection confirmation signal is authentic and reliable, avoiding misjudgments caused by unreasonable charging pile detection methods.
[0023] In the above technical solution, after the charging gun is inserted into the charging port of the target vehicle and triggers the insertion event, the charging pile initiates a Bluetooth connection request to all legitimate target vehicles in the list of legitimate target vehicles, and establishes a Bluetooth communication connection with the legitimate target vehicles that respond to the Bluetooth connection request. Interactive authentication is performed on the legitimate target vehicles through the Bluetooth communication connection. If the interactive authentication fails, the Bluetooth connection between the charging pile and the legitimate target vehicle is disconnected. This design immediately disconnects the Bluetooth connection after interactive authentication failure, preventing vehicles that have failed authentication from continuously occupying Bluetooth communication resources. This ensures that the charging pile can promptly provide Bluetooth connection opportunities for other legitimate target vehicles, prevents unauthorized vehicles from attempting to crack or interfere with the charging control system through continuous connection, reduces security risks, and ensures the stable operation of the entire charging control system.
[0024] Example 2 A charging control method based on Bluetooth Low Energy technology, such as Figure 2 As shown, the system obtains vehicle information bound to the target charging station to obtain a list of legitimate target vehicles. After the charging gun is inserted into the charging port of the current vehicle, triggering the insertion event, a Bluetooth connection request is initiated to all legitimate target vehicles in the list to establish a Bluetooth communication connection and perform interactive authentication. After successful interactive authentication, the system checks whether the charging port of the legitimate target vehicle is connected to the charging gun and whether the charging gun of the target charging station is connected to the charging port of the vehicle. If the charging port of the legitimate target vehicle is connected to the charging gun, and the charging gun of the target charging station is connected to the charging port of the vehicle, the status is considered to be matched, and the target charging station starts charging the current vehicle.
[0025] The specific methods for charging control include the following steps: Obtain vehicle information that is associated with the target charging station to obtain a list of legitimate target vehicles; After the charging gun of the target charging station is inserted into the charging interface of the current vehicle and the insertion event is triggered, a Bluetooth connection request is initiated to all legitimate target vehicles in the list of legitimate target vehicles, and a Bluetooth communication connection is established with the legitimate target vehicles that respond to the Bluetooth connection request. The legitimate target vehicles are then interactively authenticated through the Bluetooth communication connection. After the interactive authentication is successful, the system detects whether the charging port of the legitimate target vehicle is connected to the charging gun through the established Bluetooth communication connection, and detects whether the charging gun of the target charging pile is connected to the charging port of the vehicle. If the charging port of the legitimate target vehicle is connected to the charging gun, and the charging gun of the target charging pile is connected to the charging port of the vehicle, the status is determined to be matched, and the target charging pile starts charging the current vehicle.
