Electric vehicle road wireless charging system

Abstract

The invention relates to an electric vehicle road wireless charging system which comprises an electric vehicle and a road charging device. An electromagnetic induction receiving device and an induction device are arranged at the bottom of the electric vehicle. The induction device is located at the front portion of the vehicle. The electromagnetic induction receiving device is located in the middle or at the rear portion of the vehicle and comprises a controller, a battery pack, an electromagnetic conversion device and a receiving coil. The receiving coil is electrically connected with the electromagnetic conversion device. The electromagnetic conversion device is electrically connected with the battery pack. The controller is electrically connected with the electromagnetic conversion device and the induction device. The road charging device comprises a charging coil, a cable, a charging controller and an inductor. The cable is communicated with the charging coil and connected with an external power source. The charging controller is connected with the inductor and the charging coil. By the adoption of the electric vehicle road wireless charging system, a charging method is simple, the vehicle can be charged without being parked, the travel mileage of the electric vehicle can be greatly increased, and the popularization of the electric vehicle is facilitated.

Description

technical field [0001] The invention belongs to the field of wireless charging, and in particular relates to a road wireless charging system for electric vehicles. Background technique [0002] Due to the limited reserves of petroleum energy substances, with the rapid expansion of industry, economy and consumption scale, the current supply of petroleum is increasingly tight, especially the future development of traditional fuel-powered vehicles will be severely restricted. It is imperative to develop new high-efficiency vehicles that utilize different forms of energy. [0003] my country is very active in new energy vehicles, mainly because: first, the shortage crisis of traditional energy sources and the objective requirements of environmental protection, our country's dependence on foreign oil is increasing year by year, and at this time the automobile industry as a whole is in the midst of In the stage of adjusting direction, new energy vehicles are the demand of the enti...

Problems solved by technology

[0004] Now electric vehicles are the main development direction of new energy vehicles, but due to the small battery capacity, large volume and weight, the current electric vehicles can only travel more than 100 kilometers on a single charge, and the charging time takes several hours. During long-distance driving, the shortcomings of charging cars are revealed
