Overview of wireless charging devices for electric vehicle applications

China [CN]

Introduction: The application of wireless charging equipment in electric vehicles is an innovative charging method. It uses electromagnetic induction or magnetic resonance to achieve wireless transmission of electric energy from the transmitter to the receiver, providing power supply for electric vehicles. The following is an overview of wireless charging equipment for electric vehicles:

Basic principle: Wireless charging technology is mainly based on the principle of electromagnetic induction. It realizes wireless transmission of electric energy by forming a changing electromagnetic field between the transmitter and the receiver. This technology can be divided into electromagnetic induction and magnetic resonance. The electromagnetic induction type realizes energy transmission through electromagnetic induction coupling between the sensor and the receiver, while the magnetic resonance type requires two resonant devices, located on the charger and the charging device respectively, and transmits high-frequency signals to the resonant device of the transmitter to establish a stable electromagnetic field between the resonant devices of the receiver and the transmitter to achieve power transmission.

Application in automobiles: Improve charging convenience: Wireless charging equipment makes charging electric vehicles more convenient, without plugging and unplugging cables, reducing cumbersome operations and safety hazards.

Other advantages: Extending driving range: Through wireless charging, electric vehicles can continuously receive power during driving, thereby extending driving range and alleviating "mileage anxiety".

Types of wireless charging equipment include road wireless charging: by burying wireless charging coils under the road, when the electric car drives over the coil, it can automatically receive electricity for charging. This technology allows electric vehicles to continue charging while driving, but it requires large-scale transformation of existing road infrastructure, which is costly.

In summary, wireless charging technology has brought revolutionary changes to the charging method of electric vehicles, improving the convenience, environmental protection and compatibility of charging. With the continuous maturity of technology and the reduction of costs, wireless charging is expected to become the mainstream way of charging electric vehicles. In the future, wireless charging equipment will play a more important role in the field of electric vehicles and promote the rapid development of the electric vehicle industry.
