The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
A wireless charging method of an electric vehicle according to an embodiment of the present invention is described below with reference to fig. 1 to 4.
According to the wireless charging method provided by the embodiment of the invention, the electric automobile is provided with the electric energy receiving device 1, and the power supply device 2 is arranged below the road surface.
As shown in fig. 1, the wireless charging method according to the embodiment of the present invention includes the steps of:
the first step is as follows: calculating the flatness of the road surface;
specifically, in the daily driving process of the electric vehicle, various road conditions are often met, the road conditions can be better monitored in real time by calculating the road flatness, and the electric vehicle can take corresponding measures according to the road flatness and conditions such as bumpy road sections to be met.
The second step is that: acquiring a preset charging distance between the electric energy receiving device 1 and the power supply device 2;
specifically, the charging efficiency between the electric energy receiving device 1 and the power supply device 2 varies with the distance between the two, and since the chassis heights of different vehicles and the installation positions of the electric energy receiving device 1 also differ, the preset charging distance also varies, and the preset charging distance is often set to a distance at which the power supply device 2 can better charge the electric energy receiving device 1, and thus, by acquiring the current preset charging distance, the standard of whether the electric energy receiving device 1 is in a position with higher charging efficiency can be better taken as the standard.
The third step: acquiring the actual charging distance between the electric energy receiving device 1 and the power supply device 2;
specifically, during the driving of the electric vehicle, since the road surface of the driving road is not flat, the electric vehicle may bump along with the unevenness of the road surface: when the road surface has a bulge, the distance between the electric energy receiving device 1 and the power supply device 2 is from far to near; when the road surface has a depression, the distance between the electric energy receiving device 1 and the power supply device 2 is from near to far.
It can be understood that, when the distance between the power receiving device 1 and the power supply device 2 of the electric vehicle changes, the charging efficiency of the electric vehicle is affected no matter whether the road surface has a protrusion or a depression. Whether the charging efficiency is changed or not can be well judged by acquiring the actual charging distance.
The fourth step: and judging whether the actual charging distance is equal to the preset charging distance, if not, adjusting the height of the electric energy receiving device 1 to enable the absolute value of the difference between the actual charging distance and the preset charging distance to approach zero.
That is to say, through the height of adjustment electric energy receiving arrangement 1 for the unlimited preset distance that charges that is close to of actual charging distance, thereby reduce because of the road surface is uneven the actual charging distance that brings lengthens or shorten, lead to the appearance of electric automobile charge efficiency low scheduling problem.
According to the wireless charging method provided by the embodiment of the invention, the electric automobile can judge the road condition to be driven according to the calculation result by calculating the road flatness, and the distance between the electric energy receiving device 1 and the power supply device 2 can be better kept at the preset charging distance in the driving process of the electric automobile by adjusting the height of the electric energy receiving device 1, so that the electric automobile is ensured to have higher charging efficiency in the driving process, the electric energy loss is effectively reduced, and the charging efficiency is high.
In some embodiments of the present invention, the preset charging distance is an optimal charging distance between the electric energy receiving device 1 and the power supply device 2 when the charging efficiency is the highest, so that the electric vehicle adjusts the actual charging distance according to the road flatness to make the actual charging distance the same as the preset charging distance, which can better ensure that the electric vehicle maintains the optimal charging efficiency, and the charging efficiency is high.
In still other embodiments of the present invention, obtaining the actual charging distance between the power receiving device 1 and the power supply device 2 includes: and acquiring the position information of the electric energy receiving device 1 of the electric automobile, and acquiring the actual charging distance according to the pavement evenness and the position information. That is to say, the position of the electric energy receiving device 1 on the road surface is located in real time, and the calculation result of the road surface flatness is compared, so as to obtain the road surface flatness of the position corresponding to the electric energy receiving device 1, it can be understood that the road surface flatness represents the height position of the power supply device 2, and then the actual charging distance between the electric energy receiving device 1 and the power supply device 2 is obtained.
In still other embodiments of the present invention, after the actual charging distance between the power receiving device 1 and the power supply device 2 is obtained, a real-time charging distance variation curve corresponding to the electric vehicle and the road surface is generated, that is, the electric vehicle may record road surface information of a road being traveled, and record a corresponding real-time charging distance variation curve. Further, when the electric vehicle runs on a past road section, the electric vehicle may refer to the stored corresponding charging distance variation curve, so as to adjust the electric energy receiving device 1, so that the actual charging distance is kept at the preset charging distance, the charging efficiency is high, and the intelligent charging is achieved.
It should be noted that, when the stored road flatness is not changed, the electric vehicle adjusts the actual charging distance according to the above embodiment, and when it is detected that the road flatness is different from the curve stored last time, the electric vehicle may adjust the power receiving device 1 to perform adjustment, store the latest charging distance real-time change curve, and replace the previous curve information.
The invention further provides a wireless charging device of the electric automobile.
According to the wireless charging device of the electric vehicle of the second aspect of the present invention, the electric vehicle is provided with the power receiving device 1, the power supply device 2 is arranged under the road surface, and the wireless charging device includes: the device comprises a detection module, a calculation module, a first acquisition device, a second acquisition device and a processing module.

On the other hand, the first obtaining device is configured to obtain the preset charging distance between the electric energy receiving device 1 and the power supply device 2, in other words, the charging efficiency between the electric energy receiving device 1 and the power supply device 2 changes along with the distance between the electric energy receiving device 1 and the power supply device 2, because the chassis heights of different vehicles and the installation positions of the electric energy receiving device 1 also differ, the preset charging distance also differs, and the preset charging distance is often set to be the distance that the power supply device 2 can better charge the electric energy receiving device 1, so that the first obtaining device obtains the current preset charging distance, and can better serve as the standard whether the electric energy receiving device 1 is located at a position with higher charging efficiency.
In some examples, the second obtaining device is used for obtaining the actual charging distance between the power receiving device 1 and the power supply device 2, that is, during the driving process of the electric vehicle, the electric vehicle may generate jolt along with the unevenness of the road surface because the road surface of the driving road is not flat. More specifically, when the road surface has a bump, the distance between the power receiving device 1 and the power supply device 2 is from far to near; when the road surface has a depression, the distance between the electric energy receiving device 1 and the power supply device 2 is from near to far.
It can be understood that, no matter when the road surface has a protrusion or a depression, when the distance between the electric energy receiving device 1 of the electric automobile and the power supply device 2 changes, the charging efficiency of the electric automobile is affected, and the actual charging distance can be well obtained through the second obtaining device, so that whether the charging efficiency is affected or not is judged.
Optionally, the processing module is configured to adjust the height of the electric energy receiving device 1 when determining that the actual charging distance is not equal to the preset charging distance, so that the absolute value of the difference between the actual charging distance and the preset charging distance approaches to zero, that is, the height of the electric energy receiving device 1 is adjusted, so that the actual charging distance is infinitely close to the preset charging distance, thereby reducing the occurrence of problems such as too low charging efficiency of the electric vehicle due to the fact that the actual charging distance is lengthened or shortened due to uneven road surface.
According to the wireless charging device of the electric vehicle in the embodiment of the second aspect of the invention, the detection module and the calculation module are used for calculating the flatness of the road surface, so that the electric vehicle can judge the road surface condition to be driven according to the calculation result, and the distance between the electric energy receiving device 1 and the power supply device 2 can be well kept at the preset charging distance in the driving process of the electric vehicle by adjusting the height of the electric energy receiving device 1, so that the electric vehicle is ensured to have higher charging efficiency in the driving process, the electric energy loss is effectively reduced, and the charging efficiency is high.
In some embodiments of the second aspect of the present invention, the detection module includes at least one of an image detection module, an infrared detection module, and a sound detection module, that is, the detection module may detect the road condition through multiple detection methods, and is not limited to image recognition, and when the view condition is poor, the road condition may be detected through the infrared detection module and/or the sound detection module, so that the adaptability of the wireless charging device in a special scene is improved, and the detection result is relatively accurate.
In some examples, the detection module can combine devices such as car networking, map to detect, has further promoted the accuracy that detects, has guaranteed the accuracy of calculating the road flatness, and then has guaranteed that electric automobile can carry out the adjustment of electric energy receiving arrangement 1 according to the road flatness better, and charge efficiency is high.
In other embodiments of the present invention, a processing module comprises: a controller and an actuator.
Specifically, the controller is connected to the first acquisition device and the second acquisition device, respectively, to determine whether the actual charging distance is equal to the preset charging distance, and the actuator is connected to the controller, to adjust the height of the electric energy receiving device 1 according to the determination result. That is, when the actual charging distance detected by the second acquiring device is not equal to the preset charging distance detected by the first acquiring device, the controller acquires the information and transmits the information to the actuator, and the actuator receives the signal and starts to adjust the electric energy receiving device 1.
Further, when the actual charging distance is greater than the preset charging distance, the actuator controls the electric energy receiving device 1 to approach the power supply device 2 until the actual charging distance is equal to the preset charging distance; when the actual charging distance is smaller than the preset charging distance, the actuator controls the electric energy receiving device 1 to be far away from the power supply device 2 until the actual charging distance is equal to the preset charging distance; when the actual charging distance is equal to the preset charging distance, the actuator keeps the position of the electric energy receiving device 1 unchanged.
Alternatively, referring to fig. 4, the actuator includes: the multi-link mechanism 3 is arranged on a chassis of the electric automobile, the electric energy receiving device 1 is arranged at the tail end of the multi-link mechanism 3, namely, the multi-link mechanism 3 can drive the electric energy receiving device 1 to finish instructions such as approaching to, keeping away from the power supply device 2 or keeping the electric energy receiving device stationary according to signals of the controller, and the multi-link mechanism 3 is strong in mobility and multiple in movable angle, so that adjustment of multiple angles of the electric energy receiving device 1 can be well met. And, the electric energy receiving arrangement 1 is installed on vehicle chassis through many link mechanism 3, need not to destroy the automobile body structure, and the assembly is convenient, and easily later maintenance.
It should be noted that the actuator may be any other mechanism capable of receiving the controller signal and driving the power receiving device 1 to move according to the instruction, which is merely illustrative and not limiting.
