Road-automobile interactive wireless charging system for electric automobile

Abstract

The invention relates to a road-vehicle interactive wireless charging system for an electric automobile. The road-vehicle interactive wireless charging system comprises a power energy transmitting end and a power energy receiving end, wherein the power energy transmitting end comprises a power energy source, a power energy storage module, a transmitting end controller and a first electromagnetic system; the transmitting end controller comprises a pressure sensor, a digital processing core module, a driving chip, and a heavy-power MOSFET (Metal Oxide Semiconductor Field Effect Transistor) chip or IGBT (Insulated Gate Bipolar Transistor); the digital processing core module comprises a communication module, a pressure acquisition module and a calculation module; the first electromagnetic system comprises a first resonant capacitor and a primary coil; the power energy receiving end comprises a second electromagnetic system, a receiving end controller and a load; the second electromagnetic system comprises a second resonant capacitor and a secondary coil; and the receiving end controller comprises a high-frequency rectifier bridge and an LC (Liquid Crystal) filtering circuit. The road-vehicle interactive wireless charging system disclosed by the invention has the advantages of simple structure, mounting and arrangement and small size; and the road-vehicle interactive wireless charging system can be used for charging a battery of the electric automobile without staying the electric automobile or influencing normal driving of the electric automobile and can be widely applied to various electric automobiles.

Description

technical field [0001] The invention relates to a wireless charging system, in particular to a road-vehicle interactive electric vehicle wireless charging system based on the utilization of new energy such as solar energy. Background technique [0002] At present, many big cities in our country are facing serious environmental problems, and automobile exhaust is one of the main sources of pollution. As of June 2011, there were an average of 75.7 cars per 1,000 people in my country. With the rapid development of my country's economy, if China's per capita car ownership reaches the current global level, that is, there are 140 cars per 1,000 people, the number of cars in my country will increase by 10 times, and the environmental pollution caused by traditional cars cannot be underestimated. watch for. Compared with traditional cars, on the one hand, pure electric vehicles not only save fuel tanks, engines, transmissions, cooling systems and exhaust systems, but also have lowe...
