[0053] The first embodiment of the present invention relates to an information push method for a charging device, which is applied to a control module of the charging device (for example, a device with processing capabilities such as a controller and a processor), and the control module can be a dedicated controller or a charging controller CCU of a charging component. A display device (i.e., a display screen) is mounted on the housing of the charging device, and the control module is connected to the display device in communication, and can control the display device to display corresponding content.

[0054] The charging component of the charging device is used to communicate and charge the electric vehicle when the charging gun of the electric vehicle is connected. It generally includes: a charging module, a controller and a power module. The power module is generally an external AC power supply to power the charging component, and the controller is used to exchange signals with the electric vehicle and the working status of the controller when the charging module is working and the charging parameters during the charging process to ensure the safety and stability of charging the electric vehicle; the detailed working principle and structure of the charging component will not be described in detail, and reference can be made to the structure of the existing charging device.

[0055] The specific process of the information push method of the charging device in this embodiment is as follows: Figure 1 shown.

[0056] Step 101, after the charging device establishes a communication connection with the vehicle, the vehicle characteristic information of the vehicle is obtained.

[0057] Specifically, after the charging gun of the vehicle is inserted into the charging interface of the charging device, the charging controller of the charging device shakes hands with the vehicle (battery management system BMS, electronic control system VCU, etc.) and exchanges information, so that the charging device can obtain vehicle characteristic information from the vehicle, and the charging device and the vehicle can communicate through the CAN bus and other methods; the charging device is, for example, a DC charging pile. Among them, the vehicle characteristic information can characterize some characteristics of the vehicle, such as the vehicle type, such as pure electric vehicles, extended-range vehicles; sedans, off-road vehicles, etc. In addition, the information sent by the vehicle to the charging device can also include vehicle charging characteristic information, which characterizes the type of vehicle battery module, charging voltage, charging current range and other information, so as to provide charging control for the charging device when charging the battery module of the vehicle.

[0058] The charging device obtains the vehicle characteristic information of the vehicle in the following manner:

[0059] The vehicle characteristic information is obtained based on the vehicle identification information sent by the vehicle to the charging device; specifically, when the vehicle shakes hands with the charging device, the vehicle identification information of the vehicle is sent to the charging device, and the vehicle identification information includes the address information of the vehicle. Different vehicle manufacturers may use the same address or address segment, so that the address information of the vehicle can be compared with the address information of each stored target vehicle to determine the target vehicle corresponding to the vehicle, and the manufacturer information of the target vehicle corresponding to the vehicle is used as the manufacturer information of the vehicle; for example, the address information of the vehicle is such as the MAC address of the vehicle, etc. The MAC address of the vehicle is usually provided by the BMS system of the vehicle, and the MAC addresses of different models are different. Therefore, the MAC address of the vehicle can be compared with the MAC addresses of all currently stored known vehicles to obtain a target vehicle matching the MAC address. The target vehicle is the same or similar to the model of the current vehicle, so that the model information of the target vehicle can be used as the vehicle characteristic information of the current vehicle.

[0060] In some embodiments, the MAC address of the vehicle is generally configured by the manufacturer of the vehicle. Multiple models under the same manufacturer will be randomly selected from a certain MAC address segment, that is, the first few digits of the MAC addresses of all models produced by the same manufacturer are the same. The manufacturer information of the current vehicle can only be determined based on the comparison between the MAC address of the current vehicle and the MAC address segment used by each manufacturer; then, based on the manufacturer information of the vehicle and the charging characteristic information of the vehicle, the model information of the vehicle is identified, and the vehicle characteristic information includes the model information. Specifically, the manufacturer information of the vehicle may include the manufacturer identification information and all models corresponding to the manufacturer. Each vehicle model has corresponding charging physical parameters, such as the type of battery module, the capacity of the battery module, the range of charging current and charging voltage, etc.

[0061] The vehicle's charging characteristic information may include the current vehicle's charging physical parameters, thereby comparing the current vehicle's charging physical parameters with the charging physical parameters of all vehicle models corresponding to the same manufacturer, finding a vehicle model that matches the current vehicle's charging characteristic information, and obtaining the current vehicle's model information.

[0062] Furthermore, if the model information of the current vehicle cannot be determined by comparing the vehicle charging characteristic information of the current vehicle with the charging physical parameters of all models corresponding to the same manufacturer, the vehicle can be charged based on the vehicle charging characteristic information of the current vehicle after the charging device and the current vehicle complete charging confirmation, and the charging status information of the current vehicle is recorded during the charging process. The charging characteristic information includes the charging status information, and the charging status information of the current vehicle is compared with the charging status information of all models of the same manufacturer to find the model that matches the charging status of the current vehicle, thereby obtaining the model information of the current vehicle.

[0063] Among them, the vehicle's charging status information may include the vehicle's current charging mode (fast charging or slow charging), and the charging curve information under the current charging mode (which can be the current and voltage of the battery module at each moment during charging, or the charging power). Therefore, when comparing the charging status information of the current vehicle with the charging status information of all models of the same manufacturer, the charging curve of the current vehicle is compared with the charging curves of all models of the same manufacturer under the same charging mode as the current vehicle, and the model that matches the charging status of the current vehicle is found, thereby obtaining the model information of the current vehicle.

[0064] In some embodiments, the housing of the charging device is also equipped with an image acquisition device (such as a camera), and the control module can acquire the image of the vehicle through the image acquisition device, and try to obtain the vehicle feature information of the vehicle by identifying the image of the vehicle. The specific method is, for example: if the image of the rear of the vehicle is acquired, if there is a model text on the rear of the vehicle, the model of the vehicle can be directly acquired through text recognition; if there is no model text on the image of the rear of the vehicle or the acquired image is not an image of the rear of the vehicle, the overall image of the vehicle can be recognized to try to obtain the model of the vehicle; or the characteristics of the vehicle can be acquired by recognizing the license plate of the vehicle, such as by recognizing the color of the license plate, a blue license plate is usually a fuel vehicle, and a green license plate is usually an electric vehicle. Therefore, a combination of multiple methods can be used to obtain a more accurate vehicle model.

[0065] In one example, the charging device also has a built-in wireless communication module, such as Bluetooth, wifi, NFC, 4G, 5G and other wireless communication modules, so that the charging device can also be connected to the device in the vehicle (such as the vehicle machine device) or the owner's device of the vehicle (such as mobile phones and other electronic devices) through the wireless communication module, so that the vehicle characteristic information can be obtained from the vehicle or the owner's device through wireless communication. The vehicle characteristic information can be directly read from the device in the vehicle or the vehicle owner's device. The vehicle characteristic information preset in the device can also be prompted to enter some vehicle characteristic information, such as the vehicle model, through the device.

[0066] Step 102: based on the vehicle characteristic information of the vehicle, obtain push information corresponding to the vehicle.

[0067] Specifically, from the foregoing content, it can be seen that the vehicle characteristic information can characterize the vehicle model and other characteristics, thereby based on the vehicle model, push information corresponding to the vehicle model can be obtained. For example, if the vehicle is a pure electric vehicle, information related to the pure electric vehicle can be pushed to it, such as pure electric vehicle insurance information and external devices available for pure electric vehicles (such as discharge guns).

[0068] In some embodiments, based on the vehicle model information of the vehicle, historical push information of target vehicles of the same type as the vehicle is obtained; based on the vehicle model information of the vehicle and the historical push information, push information corresponding to the vehicle is obtained. That is to say, after obtaining the vehicle model information of a certain vehicle, if corresponding information has been pushed to a target vehicle of the same model before, the historical push information previously pushed to the target vehicle is first obtained. The historical push information can also be triggered based on previous user clicks to view or other methods (such as scanning a code, purchasing, etc.) to sort all the information; then, combined with the arrangement order of all the information in the historical push information, all the push information of the current vehicle of the model is adjusted in order or content, so that the push information corresponding to the vehicle finally obtained can be more in line with the current model and the interests of the user.

[0069] In one example, the vehicle characteristic information obtained in step 101 also includes: charging status information of the vehicle battery, which indicates some parameters generated by the vehicle during the charging process, such as battery capacity, charging power change curve, battery charging and discharging efficiency, etc., so that the vehicle battery quality can be evaluated based on these parameters to obtain the battery evaluation information of the vehicle, and the battery evaluation information characterizes the performance of the vehicle battery. The battery evaluation information is, for example, the battery performance of the vehicle represented by a score, so that the battery evaluation information can be added to the push information, and the battery evaluation information can also be displayed on the display module of the charging device later, so that the owner of the vehicle can obtain the information of the vehicle battery.

[0070] Step 103: display the push information on a display module of the charging device.

[0071] Specifically, after acquiring the push information of the current vehicle, the control module may control the display module to display the push information so that the user can view the push information.

[0072] In some embodiments, the housing of the charging device is also equipped with a human proximity sensor. The control module can detect whether a person is approaching through the human proximity sensor. If a person is detected approaching, the push information is displayed on the display module; if no person is detected approaching, the charging device is controlled to maintain the current display mode. The current display mode can be the previous advertisement or the low power consumption mode, thereby making the push information display more intelligent.

[0073] In this embodiment, after the user's vehicle is connected to the charging device, the vehicle characteristic information of the vehicle is first obtained. The vehicle characteristic information can represent some characteristics of the vehicle. The push information of the vehicle obtained based on the vehicle characteristic information can match the characteristics of the vehicle. When the push information is subsequently displayed on the display module of the charging device, it is easier to arouse the interest of the user using the vehicle, which can achieve better promotion effects, realize personalized information push, and have a better user experience.

[0074] The second embodiment of the present invention relates to a charging device, comprising: the charging device can be a common charging pile, please refer to Figure 2 The charging device includes: a control module 1, a charging component 2 and a display module 3; the control module 1 is communicated with the charging component 2 and the display module 3 respectively.

[0075] The control module is a device with processing capabilities such as a controller and a processor. The control module can be a dedicated controller or a charging controller CCU of a charging component.

[0076] The charging component is used to communicate and charge with the charging connector of the vehicle. When the charging gun of the electric vehicle is connected, the charging component communicates and charges with the electric vehicle. It generally includes: a charging module, a controller and a power module. The power module is generally an external AC power supply to power the charging component. The controller is used to exchange signals with the electric vehicle and the working status of the controller when the charging module is working and the charging parameters during the charging process to ensure the safety and stability of charging the electric vehicle. The detailed working principle and structure of the charging component will not be described in detail, and reference can be made to the structure of the existing charging device.

[0077] The display module is used for displaying information. The display device is a display screen, which is mounted on the outer shell of the charging pile. The control module is connected to the display device for communication and can control the display device to display corresponding content.

[0078] The control module is used to execute the information pushing method of the charging device of the first embodiment.

[0080] The image acquisition device is used to acquire images within a set range in front of the charging device;

[0081] The control module is used to collect the image of the vehicle through the image collection device installed on the charging device, and identify the image of the vehicle to obtain vehicle feature information of the vehicle.
