Wireless EV charging utilizes the principles of what technology?

Wireless EV charging primarily utilizes the principles of induction. This technology is based on electromagnetic fields and involves the transfer of energy between two coils: one that is powered (the transmitter) and one that receives power (the receiver). When alternating current flows through the primary coil, it creates a changing magnetic field that induces a voltage in the secondary coil. This principle is highly efficient for transferring energy over short distances, making it well-suited for charging electric vehicles without physical connectors.

In the context of electric vehicle charging, induction allows for greater convenience, as drivers do not need to plug in their vehicles; instead, they can simply park over a charging pad, and the vehicle will be charged automatically. This use of electromagnetic induction is a key innovation in the development of wireless charging systems, helping to promote the widespread adoption of electric vehicles.
