Wireless EV charging utilizes the principles of what technology?

• A. Convection
• B. Induction
• C. Conduction
• D. Radiation

Answer: (B)

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.
