Description

Technical Field

[0001] This application relates to the field of wireless charging technology, and in particular to a wireless charging method, device and electronic device. Background Technology

[0002] With the development of electric vehicle technology, electric vehicles are being used more and more widely in daily life. In order to improve the convenience of electric vehicles, it is necessary to install charging equipment for electric vehicles on dynamic wireless charging roads. This charging equipment is used to dynamically wirelessly charge electric vehicles.

[0003] Currently, charging equipment typically consists of a transmitting coil, which charges electric vehicles through the transmitting coil, such as... Figure 1 The diagram shows an electric vehicle undergoing dynamic charging on a dynamic wireless charging road. Figure 1 In the dynamic wireless charging road, there are three transmitting coils used to charge electric vehicles. Inside each electric vehicle is a receiving coil that receives and stores the high-frequency alternating magnetic field generated by the transmitting coils. This causes a change in the magnetic flux of the receiving coil, generating alternating current of the same frequency. A rectifier converts the high-frequency alternating current generated by the receiving coil into direct current to power the load. As the electric vehicle travels along the dotted line on the dynamic wireless charging road, its direction of travel may shift left or right when it goes through a curve. This causes the receiving coil of the electric vehicle to shift away from the transmitting coils on the dynamic wireless charging road, resulting in a reduction in the current received by the receiving coil and thus low charging efficiency.

[0045] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be described in further detail below with reference to the accompanying drawings. The specific operation method in the method embodiment can also be applied to the device embodiment or the system embodiment. It should be noted that in the description of the present application, "multiple" is understood as "at least two". The association relationship of the associated objects is described, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. A and B are connected, which means that A and B are directly connected and A and B are connected through C. In addition, in the description of the present application, "first", "second", etc. are used only for the purpose of distinguishing the description, and cannot be understood as indicating or implying relative importance, nor can it be understood as indicating or implying order.

[0046] In the past technology, the electric vehicle is charged by the transmitting coil installed on the dynamic wireless charging highway, the receiving coil inside the electric vehicle receives and stores the high-frequency alternating magnetic field generated by the transmitting coil, so that the magnetic flux of the receiving coil changes, generating alternating current of the same frequency, and the rectifier converts the high-frequency alternating current generated by the receiving coil into direct current to power the load, thereby achieving the purpose of charging. However, during the process of driving through the curve, the driving direction of the electric vehicle will deviate, resulting in that the receiving coil of the electric vehicle is far away from the transmitting coil on the dynamic wireless charging highway, causing the power received by the receiving coil of the electric vehicle to decrease, and further causing the charging efficiency of the electric vehicle to be low.

[0047] In order to solve the above-mentioned problems, the present application provides a wireless charging method to improve the charging efficiency of the electric vehicle, and when the electric vehicle does not reach the transmitting coil, the transmitting coil can be opened in advance, and after the electric vehicle passes through the transmitting coil, the transmitting coil is controlled to be closed, thereby avoiding the waste of resources of the transmitting coil. The method and device of the present application embodiment are based on the same technical concept. Since the principles of the problems solved by the method and the device are similar, the embodiments of the device and the method can be mutually referred to, and the repeated parts will not be described again.

[0048] The embodiments of the present application will be described in detail below with reference to the drawings.

[0049] With reference to Figure 2 The present application provides a wireless charging method, which can improve the charging efficiency of an electric vehicle and avoid waste of resources of a transmitting coil. The implementation process of the method is as follows:

[0050] Step S21: Determine the charging speed of the electric vehicle.

[0051] In the embodiments of the present application, in order to achieve the purpose of charging, the electric vehicle needs to enter a dynamic wireless charging highway. In order to ensure that the charging efficiency of the electric vehicle can be the highest, the driving speed of the electric vehicle cannot be too fast or too slow. When the driving speed of the electric vehicle is too fast, the battery of the electric vehicle is not fully charged, thereby affecting the driving mileage of the electric vehicle. When the driving speed of the electric vehicle is too slow, when the number of electric vehicles that need to be charged increases, congestion on the dynamic wireless charging highway will be caused. Therefore, the speed of the electric vehicle driving on the dynamic wireless charging highway needs to be determined, and the speed is taken as the charging speed of the electric vehicle.

[0052] In order to determine the charging speed of the electric vehicle, the electric consumption per 100 kilometers of uniform driving, the driving distance, and the total power provided by the battery of the electric vehicle need to be obtained. Since the charging time of the electric vehicle is related to the dynamic charging power of the dynamic wireless charging highway, the dynamic charging power of the dynamic wireless charging highway also needs to be determined.

[0053] After obtaining the various parameters described above, the electric consumption per 100 kilometers of uniform driving, the driving distance, the total power provided by the battery of the electric vehicle, and the dynamic charging power of the dynamic wireless charging highway are brought into a preset algorithm to calculate the charging speed of the electric vehicle. The specific preset algorithm is as follows:

[0054]

[0055] Wherein, V is the charging speed of the electric vehicle, P1 is the electric consumption per 100 kilometers of uniform driving of the electric vehicle, P2 is the dynamic charging power of the dynamic wireless charging highway, S is the driving distance of the electric vehicle, Q is the total power provided by the battery of the electric vehicle, and x is a constant coefficient.

[0056] Specifically, the relationship between the electric consumption per 100 kilometers of uniform driving of the electric vehicle and the speed is shown in Table 1.

[0057] Vehicle speed (km / h) Electricity consumption per 100 km at constant speed (kWh) 90 13.8 100 16.88 110 21.4 120 26.7 ...... ......

[0058] Table 1

[0059] The constant coefficient x in the preset algorithm described above in the present application file is 3.6, which can be adjusted according to actual conditions, and will not be described in detail here.

[0060] In addition, the constant coefficient x in the preset algorithm described above in the present application file is 3.6, which can be adjusted according to actual conditions, and will not be described in detail here.

[0061] Based on the above method, the charging speed of the electric vehicle is determined, so that the electric vehicle can be charged on the dynamic wireless charging highway to avoid the battery of the electric vehicle not being fully charged due to too fast speed or congestion on the dynamic wireless charging highway due to too slow speed.

[0062] Step S22: Determine the vehicle driving auxiliary line corresponding to the electric vehicle based on the current position of the electric vehicle.

[0063] Since the electric vehicle is affected by the environment of the dynamic wireless charging highway during driving, the driving direction of the electric vehicle will deviate, and the greater the deviation, the farther the receiving coil inside the electric vehicle is from the transmitting coil in the dynamic wireless charging highway, resulting in lower charging efficiency of the electric vehicle. Therefore, in order to ensure the charging efficiency of the electric vehicle, it is necessary to plan the vehicle driving auxiliary line of the electric vehicle. First, the image of the electric vehicle is collected by the image collection device to determine the current position of the electric vehicle, and then the center points of each transmitting coil on the dynamic wireless highway are determined, and the center points of each transmitting coil are connected in turn to determine the center point connecting line. Finally, the current position of the electric vehicle and the center point connecting line are combined to determine the vehicle driving auxiliary line of the electric vehicle.

[0064] It should be noted that the current position of the electric vehicle is determined, which can be determined by the image collection device or by the positioning application, and will not be limited here.

[0065] Based on the above description, a schematic diagram of the electric vehicle driving according to the planned vehicle driving auxiliary line is shown in Figure 3 In Figure 3 , when the electric vehicle enters the dynamic wireless charging highway, the electric vehicle is not at the middle position of the dynamic wireless charging highway, and the current position of the electric vehicle needs to be obtained first. The vehicle driving auxiliary line of the electric vehicle is planned based on the current position of the electric vehicle and the center point connecting line of the transmitting coil, and the vehicle driving auxiliary line is two, and the electric vehicle will drive in the vehicle driving auxiliary line.

[0066] By the above method, the vehicle travel auxiliary line of the electric vehicle is determined based on the current position of the electric vehicle and the center point connecting line of the receiving coil, so that the electric vehicle can travel in the direction of the vehicle travel auxiliary line, thereby ensuring that the travel direction of the electric vehicle is the direction with the highest charging efficiency.

[0067] Step S23: Determine the pre-started N transmitting coils based on the charging vehicle speed and the vehicle travel auxiliary line, and control to start the N transmitting coils corresponding to the current position.

[0068] The above has described the process of determining the vehicle travel auxiliary line of the electric vehicle. Since the types of electric vehicles are inconsistent, the total number of transmitting coils started by the server is inconsistent when different types of electric vehicles travel on the dynamic wireless charging highway. Therefore, it is necessary to determine the pre-started N transmitting coils based on the charging vehicle speed and the vehicle travel auxiliary line of the electric vehicle. The process of determining the pre-started N transmitting coils is as follows:

[0069] Firstly, the server on the dynamic wireless charging highway needs to obtain the interval distance of adjacent transmitting coils and the start time of each transmitting coil, then read the charging vehicle speed of the electric vehicle, and finally calculate N based on the following formula:

[0070]

[0071] t 开 is the start time, S is the interval distance, and V is the charging vehicle speed.

[0072] For example: the interval distance is 1m, the start time of each transmitting coil is 3 seconds, the charging vehicle speed is 15km / h, 3 / 1*(15 / 3.6)+1=13.5, N>13.5, therefore, N is 14.

[0073] The server will obtain the real-time collection image collected by the image collection device corresponding to each transmitting coil. After the server performs noise reduction processing on the real-time collection image, the image features of the noise-reduced real-time collection image are obtained, and the obtained image features are compared with the electric vehicle image features corresponding to the electric vehicle stored in the server. When it is determined that the real-time collection image is an electric vehicle image, the N transmitting coils corresponding to the current position of the electric vehicle are started.

[0074] When the electric vehicle travels on the dynamic wireless charging highway, when the current image collected by the image collection device is a non-electric vehicle image, the server will close the transmitting coils corresponding to the current position.

[0075] For example: the schematic diagram of the electric vehicle entering the dynamic wireless charging highway for charging is as shown in Figure 4 the current image collected by the image collection device is a non-electric vehicle image, the server will close the transmitting coils corresponding to the current position.Figure 4 In the embodiment, the electric vehicle travels at the determined charging vehicle speed, the dynamic wireless charging road has n transmitting coils, each transmitting coil corresponds to an image acquisition device, transmitting coil 1 corresponds to image acquisition device 1, transmitting coil 2 corresponds to image acquisition device 2, and so on, the vehicle travel auxiliary line can be determined based on the center points of the transmitting coils, and when the electric vehicle travels according to the determined vehicle travel auxiliary line, the receiving coil of the electric vehicle is aligned with the transmitting coil in the dynamic wireless charging road, so that the charging efficiency of the electric vehicle is the highest.

[0076] Based on the above description, the charging vehicle speed of the electric vehicle and the vehicle travel auxiliary line are determined, so that when the electric vehicle travels on the dynamic wireless charging road, the receiving coil of the electric vehicle is aligned with the transmitting coil on the dynamic wireless charging road, so that the receiving coil of the electric vehicle can receive and store the maximum power of the transmitting coil, thereby improving the charging efficiency of the electric vehicle, and the transmitting coil on the dynamic wireless charging road adopts the method of early opening and late closing, thereby avoiding the waste of resources of the transmitting coil, and improving the resource utilization rate of the transmitting coil.

[0077] Based on the same inventive concept, the embodiment of the present application also provides a wireless charging device, which is thread-bound and is used to realize the function of the wireless charging method. Figure 5 The device comprises:

[0082] In one possible design, the planning module 502 is specifically used to obtain the center point of each transmitting coil in the dynamic wireless charging road, connect the center points of all transmitting coils to generate a center point connection line, calculate the target route based on the center point connection line and the current position of the electric vehicle, and use the target route as the vehicle driving auxiliary line corresponding to the electric vehicle.

[0083] In one possible design, the activation module 503 is specifically used to obtain the interval distance between adjacent transmitting coils in the dynamic wireless charging road, as well as the activation time of each transmitting coil, determine the N transmitting coils to be activated based on the interval distance, the activation time, and the charging vehicle speed, obtain the current position of the electric vehicle, and activate the N transmitting coils corresponding to the current position.

[0084] In one possible design, the startup module 503 is further configured to obtain a real-time acquired image associated with the transmitting coil, and when the real-time acquired image is determined to be an electric vehicle image of the electric vehicle, to start the N transmitting coils corresponding to the current position.

[0085] In one possible design, the startup module 503 is further configured to shut down the transmitting coil corresponding to the current position when it is determined that the current image acquired by the image acquisition device is a non-electric vehicle image.
