Quick and slow switched wireless charge device for electric car and method thereof

Abstract

The invention discloses a quick and slow switched wireless charge device for an electric car and a method thereof. The quick and slow switched wireless charge device for the electric car comprises a high-frequency power supply device, an automatic lifting lever, a high-frequency resonator, a high-insulativity sealing box, a receiving resonator, a mechanical controllable single-pole double-throw switch, a high-efficiency lithium battery pack and a high-energy density and large-capacity super capacitor part. When a user selects a quick charge mode, the single-pole double-throw switch is switched into one path of the high-energy density and large-capacity super capacitor, the automatic lifting lever ascends, and the distance of resonance coils is reduced, so that quick charge of the capacitor is achieved. When a user selects a slow charge mode, the single-pole double-throw switch is switched into a lithium battery pack, the lifting lever descends, and the distance of the resonance coils is increased, so that slow charge of the lithium battery pack by a power supply is achieved. By adopting the quick and slow switched wireless charge device for the electric car disclosed by the invention, a user can independently select the charge mode of the electric car according to the desire. By adopting the device, the electric car is more flexible and convenient to wirelessly charge after the electric car is popularized.

Description

Technical field [0001] The invention relates to a wireless charging technology for electric vehicles, in particular to a fast and slow switching wireless charging device and a method for electric vehicles. Background technique [0002] In recent years, with the continuous improvement of people's living standards and the gradual deepening of exploration of the material world, people have also placed new requirements on the transmission method and quality of electric energy. Traditional electric energy transmission is mainly carried out by direct contact of wires or conductors. Sparks, sliding wear, carbon accumulation, and exposure of live conductors caused a series of problems. Wireless power transmission is a technology that uses radio to transmit electric energy. It was first proposed by Nikola Tesla. Compared with traditional electric energy transmission methods, there is no direct electrical connection between power supply and electricity consumption during wireless power tra...

AI Technical Summary

Problems solved by technology

The wireless charging technology of electric vehicles has been extended to public transportation, such as the wireless charging of electric buses. The traditional wireless charging technology is still to bury the parking space in the parking space to wirelessly charge the cars driving into the parking space. The efficiency of this charging mode is not high. Not high, charging time is still greatly improved
