An electric vehicle dynamic adjustment wireless charging system and its control method

Abstract

The invention provides a dynamic-adjusting wireless charging system of an electric vehicle and a control method of the wireless charging system. Sensors are used for collecting information, a single chip microcomputer controls a two-level scissors type lifting mechanism, an air gap between a wireless charging vehicle-mounted receiving plate and the ground is adjusted, so that dynamic-adjusting wireless charging of the electric vehicle during driving can be realized, and the wireless charging efficiency is improved. The system mainly comprises an information collection unit, an electronic control unit and an execution unit, wherein the information collection unit is used for collecting vehicle driving information, road conditions and magnetic field information of a charging coil, the execution unit is controlled through operation of the electronic control unit to complete dynamic adjustment of the charging mechanism during driving of the electric vehicle, the wireless charging air gap is reduced on the premise of safety driving, and the wireless charging efficiency is improved.

Description

technical field [0001] The invention belongs to the field of wireless charging for electric vehicles, and in particular relates to a dynamic adjustment wireless charging system for electric vehicles and a control method thereof. Background technique [0002] Due to factors such as the depletion of oil resources, air pollution, and rising global temperatures, the development of new energy technologies has become an urgent problem to be solved for the sustainable development of my country's economy. As a means to solve these problems, new energy vehicles have been fully developed in recent years, and the improvement and perfection of new energy vehicles has also become the development direction of the future automobile industry. [0003] However, with the rapid development of electric vehicles, many problems have also emerged one by one. For example, the energy density of on-board batteries is difficult to compare with that of gasoline, so electric vehicles need to be equippe...

AI Technical Summary

Problems solved by technology

Dynamic wireless charging technology provides a solution to reduce battery capacity and reduce vehicle body weight, which can improve the effective utilization of energy, reduce the initial purchase cost of electric vehicles, and can solve the problems of current wireless charging technology such as short transmission distance and distance However, the cost of laying coils on the road surface is too high in the initial stage of dynamic wireless charging, and the environmental requirements are harsh. It is still in the research and exploration stage, so it has not yet entered the market.
