The microwave receiver on the base station receives the microwave signal transmitted by the electric vehicle and determines whether the electric vehicle is in a running state, and if so, proceeds to step 146, and if not, proceeds to step 148.

Step 146: Adjusting the microwave beam to align the microwave receiving antenna on the electric vehicle to emit microwave

When the electric vehicle is in a running state, the first microwave transceiver controls the microwave beam to align with the microwave receiving antenna on the electric vehicle to transmit the microwave, and the beam direction controller controls the microwave beam to continuously adjust the angle as the vehicle moves (as the vehicle continues to drive) The angle of irradiation of the changing microwave beam is aligned with the microwave antenna of the electric vehicle, as shown in FIG. 17; meanwhile, the microwave receiver on the electric vehicle converts the received microwave into a power by a rectification conversion charger, and the battery on the vehicle The group is charged, and the antenna direction controller continuously adjusts the angle of the microwave antenna according to the received microwave signal, and aligns the microwave slot antenna on the base station to emit microwaves. The base station records the charging start time and reports the data to the base station control center.

Step 147: Detect whether the electric vehicle is away from the coverage of the microwave beam emitted by the first microwave transceiver on the base station

Detecting whether the electric vehicle is out of the range covered by the microwave beam emitted by the first microwave transceiver on the base station, and if yes, proceeding to step 148, and if not, returning to step 146.

Step 148: Stop charging, report data

When the electric vehicle is out of the coverage of the microwave beam emitted by the first microwave transceiver on the base station or the electric vehicle stops traveling, the first microwave transceiver stops transmitting the microwave beam, and the base station records the charging end time, the charging amount and the like, and reports the data. To the base station control center.

Further, if the electric vehicle stops driving, the microwave charging device needs to stop transmitting the microwave beam to all the electric vehicles in the covered road section to protect the personnel coming out of the automobile due to an accidental reason; the base station records data such as the charging end time and the like. At the same time, it is reported to the base station control center. As a preferred embodiment, an infrared detecting device can be installed on the base station. Once an animal (mainly a human) is stopped or moved at a low speed, the microwave is stopped to protect the animal from radiation, and the animal is guaranteed to a certain extent. Health.

The electric vehicle is charged through each base station, and the process is the same as steps 144 to 148.

Step 149: The base station control center monitors whether the date is at the end of this month.

The base station control center monitors whether the date has reached the end of the month, and if so, proceeds to step 1410, and if not, proceeds to step 144.

Step 1410: Statistical billing, notify the owner to pay

When the monitoring date of the base station control center reaches the end of the month, the statistical billing work is completed at the beginning of next month, and the electric vehicle owner (the user corresponding to the mobile communication card) is notified to pay in an appropriate manner.

In summary, the technical solution provided by the present invention adopts a slot type transmitting antenna, and the slot type antenna can transmit microwaves of different angles. In combination with the microwave antenna with adjustable direction on the electric vehicle, the two antennas can be aligned with each other, and the microwave emitted by the electric vehicle is used as a positioning means to calculate the position and speed of the electric vehicle. Compared with the existing microwave charging technology, the invention has a reasonable and ingenious design, and solves the problem that the prior art cannot accurately charge wirelessly and control whether or not to charge according to actual conditions.

That is to say, the solution provided by the present invention can continuously charge the electric vehicle in motion, replenish the electric quantity, and control whether the electric vehicle is charged according to the driving state of the electric vehicle and accurately align with the microwave antenna charging on the electric vehicle. It reduces the useless radiation consumption of electric energy, improves the charging efficiency, and protects the personnel who leave the car due to accidental reasons from radiation, thereby ensuring personal health to a certain extent; at the same time, the battery pack on the electric vehicle can be reduced. Quantity and volume, which reduces the quality of the car's curb and reduces energy consumption.

The above is a preferred embodiment of the present invention, and it should be noted that those skilled in the art can also make several improvements and retouchings without departing from the principles of the present invention. These improvements and retouchings should also be considered. It is the scope of protection of the present invention.
