Dynamic wireless intelligent charging system and method for electric vehicle

Abstract

The invention provides a dynamic wireless intelligent charging system and method for an electric vehicle. The system and the method are used for wireless charging of the electric vehicle passing through a power transmission area. The system is characterized by including a control unit, a measurement unit, a signal receiving unit, a wireless charging unit, a supply wire and a power distribution unit, wherein the measurement unit and the signal receiving unit are connected with the control unit, the wireless charging unit is arranged on a road surface of the power transmission area, the supply wire is electrically connected with the wireless charging unit, and the power distribution unit is arranged on a connection circuit of the wireless charging unit and the supply wire. A first executionspeed is generated according to the average of a first real-time vehicle speed and a second real-time vehicle speed, and thus the accurate measurement of the speed of the electric vehicle is ensured.According to the first execution speed, the charging power of the wireless charging unit is adjusted, it is thus ensured that electric vehicles different in speed can be charged with the required electric quantity, and meanwhile excessive waste of electricity of the wireless charging unit is avoided. The system has the advantages that the system is convenient to use, maintenance is convenient, thepower supply effect is good, power is saved intelligently, and the system can simultaneously supply power to the vehicles.

Description

technical field [0001] The invention relates to a system and method for wireless charging of an electric vehicle, in particular to a dynamic wireless intelligent charging system and method for an electric vehicle. Background technique [0002] With the massive consumption of petrochemical energy and the aggravation of environmental pollution, mainstream countries in the world have started research on new energy vehicles. Traditional cars have also begun to gradually transform into new energy vehicles, so the charging methods suitable for new energy electric vehicles are becoming more and more diverse. [0003] At present, in order to realize the wireless charging function of moving new energy electric vehicles, some patents such as the patent application number CN201610282387.3 "electric vehicle wireless charging method, device and system" have emerged. The vehicle sends a detection signal to determine the type of car, and charges the electric car through a wireless sending...

AI Technical Summary

Problems solved by technology

But this type of method has the following problems: 1. If a plurality of wireless transmission devices are operated at the same time to supply power for a single car, a large number of wireless transmission devices will not play a charging role and cause a large amount of waste of electric energy; 2. Due to the current wireless charging The charging efficiency of the device is limited, and a long charging section is required to ensure the power supply, so the speed of the electric vehicle fluctuates obviously, and the failure of similar methods may make the car unable to charge the required electric energy; 3. The charging section is too long. The entry of multiple electric vehicles makes the use of the above-mentioned devices disorderly, thus lacking practicality
