[0089] To monitor the electromagnetic environment around electric vehicle charging facilities in real time and alleviate public concerns about the safety of the electromagnetic environment at these facilities, this application proposes an electromagnetic environment monitoring system for charging stations. The system includes electromagnetic detection equipment, temperature and humidity detection equipment, current detection equipment, vehicle detection equipment, human body detection equipment, computing and processing equipment, and a server.

[0090] Electromagnetic detection equipment is located in and / or between various charging areas of the charging station to detect the electromagnetic environment of the charging station. Temperature and humidity detection equipment is used to detect the temperature and humidity information of the charging station. Current detection equipment is used to detect the real-time charging current of each charging vehicle. Vehicle detection equipment is used to detect the number of vehicles in the charging station. Human body detection equipment is used to detect whether there are human bodies near the charging vehicles.

[0091] The computing and processing equipment determines whether the electromagnetic environment of the charging station is harmful to humans based on electromagnetic environment and temperature and humidity information. If it determines that the electromagnetic environment is harmful to humans and a human is present near the corresponding charging vehicle, it sends a stay-away warning message to that person. It also determines the current charging stage of each charging vehicle based on its real-time charging current and reports the electromagnetic environment, temperature and humidity information, the current charging stage of each vehicle, and the number of vehicles to the server. The server is used for electromagnetic environment monitoring and charging scheduling of various charging stations within the area.

[0092] In some embodiments, the process of the computing processing device monitoring the electromagnetic environment of the charging station can be as follows: receiving the electromagnetic environment of each charging area of ​​the charging station, the temperature and humidity information of the charging station, the real-time charging current of each charging vehicle, and the number of vehicles in the charging station; determining the target charging area with electromagnetic hazards based on the electromagnetic environment of each charging area and the temperature and humidity information of the charging station; sending an image acquisition command to a human body detection device, which instructs the human body detection device to acquire a first image of the target charging area; acquiring the first image sent by the human body detection device, and if a human body is present in the first image, sending a reminder message to a reminder device located in the target charging area so that the reminder device broadcasts the reminder message; and determining the current charging stage of each charging vehicle based on the real-time charging current of each charging vehicle.

[0093] For example, the process by which a computing device determines a target charging area with electromagnetic hazards based on the electromagnetic environment of each charging area and the temperature and humidity information of the charging station may include:

[0094] Acquire a second image of the charging area adjacent to the first charging area to determine whether there is a charging vehicle in the second image; or, determine whether there is a charging vehicle in the charging area adjacent to the first charging area based on the real-time charging current of the charging area adjacent to the first charging area, where the first charging area is any charging area in the charging pile.

[0095] If there are no charging vehicles in the charging areas adjacent to the first charging area, the presence of electromagnetic hazards in the first charging area is determined based on the electromagnetic environment detected by the electromagnetic detection equipment located in the first charging area and the temperature and humidity information of the charging station.

[0096] If there are charging vehicles in the charging areas adjacent to the first charging area, the presence of electromagnetic hazards in the first charging area is determined based on the electromagnetic environment detected by the electromagnetic detection equipment located in the first charging area, the electromagnetic environment detected by the electromagnetic detection equipment located between the first charging area and the adjacent charging areas, and the temperature and humidity information of the charging station.

[0097] For example, the process by which the computing processing device determines the current charging stage of each charging vehicle based on the real-time charging current of each charging vehicle may include: obtaining vehicle characteristic information of a first charging vehicle, wherein the first charging vehicle is any charging vehicle; retrieving the corresponding charging current characteristics based on the vehicle characteristic information, wherein the charging current characteristics include the charging current and the charging duration corresponding to the charging current; and determining the current charging stage of the first charging vehicle based on the real-time charging current and the charging current characteristics of the first charging vehicle.

[0098] In some embodiments, the process of the server performing charging scheduling can be as follows: receiving charging request information, which is sent to the server by the vehicle terminal and includes vehicle type, vehicle current location, vehicle battery type, remaining battery capacity, and user destination; determining target charging stations based on vehicle type, vehicle current location, vehicle battery type, remaining battery capacity, user destination, the number of vehicles reported by each charging station, and the current charging stage of each charging vehicle, wherein there can be one or more target charging stations; sending the target charging stations to the vehicle terminal and generating route navigation information.

[0099] For example, the process by which the server determines the target charging station may include: determining the vehicle's driving area based on the vehicle type, the vehicle's current location, and the remaining battery capacity, wherein the vehicle's driving area represents the area formed by the distance the vehicle can travel based on the remaining battery capacity; cropping a fan-shaped area from the vehicle's driving area based on the destination; retrieving the number of vehicles reported by the charging stations located in the fan-shaped area and the current charging stage of each charging vehicle; and generating charging station recommendation information based on the vehicle's battery type, the number of vehicles, and the current charging stage of each charging vehicle.

[0100] Alternatively, the computing and processing equipment can simply summarize the information collected by each device in the corresponding charging station and report it to the server without further processing. The server then determines the target charging area for electromagnetic hazards within each charging station and the current charging stage of each vehicle.

[0101] For example, each charging station is equipped with a computing processing device, multiple electromagnetic detection devices, at least one temperature and humidity detection device, multiple current detection devices, a set of vehicle detection devices, and a set of human body detection devices. The electromagnetic detection devices, temperature and humidity detection devices, current detection devices, vehicle detection devices, and human body detection devices are communicatively connected to the computing processing device.

[0102] The aforementioned electromagnetic detection devices are located in various charging areas of the charging station and / or between various charging areas, and at least one of the aforementioned temperature and humidity detection devices is located in the charging station.

[0103] The aforementioned multiple current detection devices correspond one-to-one with each charging area of ​​the charging station and are installed on the primary coil in the charging area. They are used to collect the real-time charging current of the primary coil when the vehicle is charging and send the real-time charging current to the computing and processing equipment.

[0104] A vehicle detection device includes a first camera and a second camera, which are respectively set at the exit and entrance of the charging station. The first camera and the second camera capture vehicle images when the vehicle enters or leaves the charging station, determine whether the vehicle has entered or left the charging station, and send the detection results to the computing and processing equipment.

[0105] A human detection device includes at least one third camera positioned above each charging area to capture images of human bodies near the charging vehicle in the charging area.

[0106] Figure 1 This is a schematic diagram of the structure of a charging station electromagnetic environment monitoring system according to an embodiment of this application. See also... Figure 1 The server corresponds to charging station 1, ..., charging station N, where N is an integer greater than or equal to 2. This means the server's region covers charging stations 1 through N, and all data from charging stations 1 through N is sent to this server. The server's region can be a city, a town, or a region divided according to the server's capabilities; there are no restrictions on this.

[0107] The charging station 1 is equipped with a first computing and processing device, a temperature and humidity detection device 1, an electromagnetic detection device 1, a current detection device 1, a camera 11, a camera 12, and a camera 13.

[0108] Temperature and humidity detection device 1 is installed in charging station 1, close to the charging area, and can measure the temperature and humidity of the charging station and each charging area. Multiple electromagnetic detection devices 1 are installed in each charging area of ​​the charging station and / or between charging areas to detect the electromagnetic environment around the vehicle during charging. Specifically, if no vehicle is charging in a charging area, the electromagnetic detection device 1 in that area is not operational; when a vehicle is charging in a charging area, the electromagnetic detection device 1 in that area is operational.

[0109] There are multiple current detection devices 1, and at least one current detection device 1 is set in each charging area. The current detection device 1 can collect the real-time charging current of the primary coil when the charging vehicle is charging. The first calculation and processing device can determine the current charging stage of the charging vehicle based on the real-time charging current.

[0110] Cameras 11 and 12 can be installed at the entrance and exit of the charging station, respectively, to capture vehicle images of vehicles entering and leaving the charging station and send them to the first computing and processing device. Based on the vehicle images, the first computing and processing device can identify the vehicles entering and leaving the charging station, thereby obtaining information such as the number of vehicles in the charging station and the relationship between time and the entry and exit of vehicles.

[0111] Camera 13 is installed inside the charging station, and can be positioned above the charging area. When the first computing device determines that the electromagnetic environment of a charging area poses a hazard to human health, it uses camera 13 to capture a first image of that area. Then, the first computing device determines whether a human is present near the charging area based on the first image. If a human is present, the first computing device can send a warning message to a nearby alert device. The alert device then broadcasts the warning message to remind the person near the charging area to be aware of the electromagnetic hazard and to move away from the charging area.

[0112] Charging station N is equipped with an Nth computing and processing device, a temperature and humidity detection device N, an electromagnetic detection device N, a current detection device N, cameras N1, N2, and N3. For details regarding the location and function of each device and camera in charging station N, please refer to the location and function of each device and camera in charging station 1; further details will not be provided here.

[0113] In addition, the computing and processing equipment at each charging station can report information such as the electromagnetic environment, temperature and humidity, the current charging stage of each vehicle, and the number of vehicles to the server. The server then monitors the electromagnetic environment and schedules charging at each charging station within the area based on the information reported by each station.

[0114] Optionally, the first computing processing device can also send information such as the current charging stage, charging time, cost, and whether there are any hazards in the electromagnetic environment to the user terminal of the driver of the charging vehicle, so that the driver can understand the relevant information.

[0115] Based on the aforementioned electromagnetic environment monitoring system for charging stations, this application also provides a charging control method for charging stations, which can be applied to... Figure 1 The computing processing device or server shown. (Refer to...) Figure 2 The charging control method for this charging station is described in detail below:

[0116] Step 201: Obtain the electromagnetic environment of each charging area of ​​each charging station in the region, the temperature and humidity information of the charging station, the real-time charging current of each charging vehicle, and the number of vehicles in the charging station.

[0117] For example, electromagnetic environment of each charging area of ​​a charging station can be detected by electromagnetic detection equipment, temperature and humidity information of the charging station can be detected by temperature and humidity detection equipment, real-time charging current of each charging vehicle can be detected by current detection equipment, and number of vehicles in the charging station can be determined by vehicle detection equipment.

[0118] In one scenario, the electromagnetic detection device, temperature and humidity detection device, current detection device, and vehicle detection device can send the detected information to the computing processing device at preset time intervals. Alternatively, the computing processing device sends an information acquisition command to the electromagnetic detection device, temperature and humidity detection device, current detection device, and vehicle detection device, and the electromagnetic detection device, temperature and humidity detection device, current detection device, and vehicle detection device respond to the information acquisition command, collect relevant information, and send it to the computing processing device.

[0119] Step 202: Based on the electromagnetic environment of each charging area and the temperature and humidity information of the charging station, determine the target charging area where electromagnetic hazards exist.

[0120] In some embodiments, the implementation of step 202 may include:

[0121] Acquire a second image of a charging area adjacent to the first charging area, and determine whether there is a charging vehicle in the second image. The first charging area is any charging area in the charging pile.

[0122] If there are no charging vehicles in the charging areas adjacent to the first charging area, the presence of electromagnetic hazards in the first charging area is determined based on the electromagnetic environment detected by the electromagnetic detection equipment located in the first charging area and the temperature and humidity information of the charging station.

[0123] If there are charging vehicles in the charging areas adjacent to the first charging area, the presence of electromagnetic hazards in the first charging area is determined based on the electromagnetic environment detected by the electromagnetic detection equipment located in the first charging area, the electromagnetic environment detected by the electromagnetic detection equipment located between the first charging area and the adjacent charging areas, and the temperature and humidity information of the charging station.

[0124] In some other embodiments, the implementation of step 202 may include:

[0125] Based on the real-time charging current of the charging areas adjacent to the first charging area, it is determined whether there are charging vehicles in the charging areas adjacent to the first charging area. The first charging area is any charging area in the charging pile.

[0126] If there are no charging vehicles in the charging areas adjacent to the first charging area, the presence of electromagnetic hazards in the first charging area is determined based on the electromagnetic environment detected by the electromagnetic detection equipment located in the first charging area and the temperature and humidity information of the charging station.

[0127] If there are charging vehicles in the charging areas adjacent to the first charging area, the presence of electromagnetic hazards in the first charging area is determined based on the electromagnetic environment detected by the electromagnetic detection equipment located in the first charging area, the electromagnetic environment detected by the electromagnetic detection equipment located between the first charging area and the adjacent charging areas, and the temperature and humidity information of the charging station.

[0128] In some embodiments, after determining the target charging area where electromagnetic hazards exist, the charging station charging control method may further include: sending an image acquisition command to a human body detection device, the image acquisition command being used to instruct the human body detection device to acquire a first image of the target charging area; acquiring the first image sent by the human body detection device, and if a human body is present in the first image, sending a reminder message to a reminder device located in the target charging area so that the reminder device broadcasts the reminder message.

[0129] In one scenario, a charging station can be equipped with one human detection device, which can be positioned above the center of one side of the charging area. Alternatively, a charging station can be equipped with multiple human detection devices, which can be evenly distributed above one side of the charging area.

[0130] For example, after receiving the image acquisition command, the human detection device parses the command to obtain the shooting angle. The device then converts this angle to its coordinates in its coordinate system and rotates accordingly to align the image acquisition angle with the target charging area. Afterward, the device acquires the first image and sends it to the computing and processing device.

[0131] In another scenario, each charging area can be equipped with a human body detection device, with each device positioned above one side of its respective charging area.

[0132] For example, after receiving the image acquisition command, the human detection device parses the command to obtain a shooting command. The human detection device then responds to the shooting command by acquiring an image, obtaining a first image, and sending the first image to the computing and processing device. At this time, the human detection device does not need to adjust the shooting angle.

[0133] In this embodiment, the human body detection device can be a high-definition camera, an infrared camera, or other devices capable of detecting human bodies; there is no limitation on the specific device.

[0134] For example, after obtaining the first image, a face detection algorithm, a limb detection algorithm, etc., can be used to detect whether there is a human body in the first image. If a human body is found, a reminder message is sent to the reminder device located in the target charging area.

[0135] In one scenario, a reminder device can be installed on one side of each charging area, and the computing processing device is communicatively connected to the reminder device. This reminder device can be a display device or an audio device, capable of broadcasting a reminder message upon response.

[0136] In another scenario, a single reminder device can be installed on one side of multiple charging areas, and the computing processing device is communicatively connected to this reminder device. This reminder device can be a display device or an audio device, capable of broadcasting the reminder message upon response.

[0137] Step 203: Determine the current charging stage of each charging vehicle based on the real-time charging current of each charging vehicle.

[0138] In some embodiments, the implementation process of step 203 may include: obtaining vehicle feature information of any charging vehicle; retrieving the corresponding charging current feature based on the vehicle feature information, wherein the charging current feature includes the charging current and the charging duration corresponding to the charging current; and determining the current charging stage of any charging vehicle based on the real-time charging current and charging current feature of the charging vehicle.

[0139] Specifically, the relationship between charging current and charging time for each vehicle can be pre-obtained, along with the charging current characteristics (and the relationship between charging current and charging time) for each vehicle. Then, by comparing the real-time charging current of the vehicle with its corresponding charging current characteristics, the current charging stage of the vehicle can be determined.

[0140] For example, the charging current and charging time corresponding to each vehicle's characteristic information can be determined by the charging station using historical charging current and charging time data during the vehicle's charging process. Specifically, the vehicle characteristic information, charging current, and charging time of each vehicle charging at the charging station can be statistically analyzed. Through a large amount of relevant data, the relationship between charging current and charging time for various vehicles can be determined relatively accurately, for example, generating a curve of charging current versus charging time.

[0141] Step 204: Receive charging request information. The charging request information is sent by the vehicle terminal to the server and includes vehicle type, current vehicle location, vehicle battery type, remaining battery capacity, and user destination.

[0142] In one scenario, a driver discovers that the vehicle's remaining battery power is low and may not be enough to reach their destination. In this case, the driver can trigger a charging request via voice or touch control. The vehicle controller responds to the request, combining information such as vehicle type, current location, battery type, remaining battery capacity, and user destination to generate a charging request message, which is then sent to the system's server.

[0143] For example, a user's destination can be obtained by inputting the destination into the map on the vehicle's display device, or by collecting the user's voice to determine the destination, or by determining it based on the user's historical location information and scene information; there is no limitation on this.

[0144] In some embodiments, the process of determining a user's destination based on the user's historical location information and context information may include:

[0145] Obtain the current date, current time, driver's facial features, and number of people in the vehicle;

[0146] Based on the current date, determine whether it is a workday. If it is a workday, retrieve the workday route and compare the current route with the workday route to determine the target workday route that matches the current route. If it is a non-workday, retrieve the non-workday route and compare the current route with the non-workday route to determine the target non-workday route that matches the current route. The workday route is obtained by statistically analyzing the vehicle's historical workday routes, and the non-workday data set is obtained by statistically analyzing the vehicle's historical non-workday routes.

[0147] The destination for this user is determined by the end of the target weekday route, or by the end of the target non-weekday route.

[0148] Optionally, after determining the user's destination, the system can announce the destination to the driver, collect the driver's voice response, and determine whether the proposed destination is the user's intended destination for this trip based on the voice response. If the proposed destination is the user's intended destination, the process ends. If the proposed destination is not the user's intended destination, the system collects the destination spoken by the driver and sets the driver's spoken destination as the intended destination for this trip.

[0149] Step 205: Based on the charging request information, the number of vehicles reported by each charging station, the current charging stage of each charging vehicle, and the electromagnetic environment, determine the target charging station, which may be one or more.

[0150] In some embodiments, the implementation process of step 302 may include: determining the vehicle driving area based on the vehicle type, the vehicle's current location, and the remaining battery capacity, wherein the vehicle driving area represents the area formed by the distance that the vehicle can travel based on the remaining battery capacity; cropping a fan-shaped area from the vehicle driving area based on the user's destination; retrieving the number of vehicles reported by charging stations located in the fan-shaped area, the current charging stage of each charging vehicle, and the electromagnetic environment; and generating charging station recommendation information based on the vehicle battery type, the number of vehicles, the current charging stage of each charging vehicle, and the electromagnetic environment.

[0151] For example, firstly, based on the vehicle's battery type, target charging stations within a fan-shaped area can be identified that can charge batteries corresponding to that vehicle's battery type. There can be one or more target charging stations. Next, for each target charging station, the availability of charging space upon arrival at that station is predicted based on the vehicle's current charging stage. Then, the target charging stations are sorted according to available charging space, travel time, and the number of vehicles at each station. For instance, target charging stations with abundant available charging space, fewer electromagnetic environment issues, shorter travel times, and fewer vehicles at each station are displayed at the top for the driver to choose from.

[0152] In one scenario, firstly, target charging areas within each target charging station where electromagnetic environment exceedances have not occurred are identified. Next, the current state of each target charging area is determined; if no vehicles are currently charging in that area, it is considered idle. Then, based on q... i =αm i +t i +βs i Calculate the recommended charging value for each target charging station, m i t represents the number of target charging areas that are idle at the i-th target charging station at the current time. i s represents the reciprocal of the predicted travel time to the i-th target charging station. i This represents the ratio of the total number of charging areas to the number of vehicles in the i-th target charging station. α and β are preset coefficients. α is determined based on the ratio of the number of target charging areas to the total number of charging areas in the i-th target charging station, and β is determined based on the ratio of the total number of charging areas to the number of vehicles in the i-th target charging station during the same historical period. i is a positive integer. Finally, target charging stations are recommended to the user in descending order of their recommended charging value.

[0153] Optionally, the above-mentioned charging station charging control method may further include: sending the target charging station to the vehicle terminal and generating route navigation information.

[0154] In some embodiments, the process of sending the target charging station to the vehicle terminal and generating route navigation information may include: storing the user destination and marking it as navigation incomplete; updating the route endpoint to the target charging station and generating a charging navigation route from the current location to the target charging station; broadcasting the charging navigation route; after the vehicle is fully charged, retrieving the user destination whose navigation is incomplete and determining with the driver whether to use the user destination whose navigation is incomplete as the route endpoint; and generating a navigation route from the current location to the user destination whose navigation is incomplete.

[0155] For example, after determining whether to include the incomplete user destination in the navigation as the route endpoint, the driver's voice information can be collected. If the voice information indicates that the incomplete user destination is included as the route endpoint, a navigation route from the current location to the incomplete user destination is generated. If the voice information indicates that the incomplete user destination is not included as the route endpoint, a new route endpoint input by the driver via voice or touch is obtained, and a navigation route from the current location to the new route endpoint is generated.

[0156] It should be noted that step 204 can be executed before steps 201 to 203, after steps 201 to 203, or simultaneously with steps 201 to 203; there is no limitation on this.

[0157] The charging control method described above, upon receiving a charging request, can determine the target charging station based on the vehicle type, current location, battery type, remaining battery capacity, user destination, number of vehicles reported by each charging station, current charging stage of each vehicle, and electromagnetic environment in the charging request information. It can recommend preferred charging stations and charging areas to the driver, monitor the electromagnetic environment of charging stations within the area to help vehicle users understand the electromagnetic environment of charging stations, and schedule charging for vehicles, thereby enabling drivers to conveniently go to charging stations to charge their vehicles.

[0158] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
