Which of the following technologies allows for charging an electric vehicle while it is in motion?

Inductive charging is a technology that allows electric vehicles (EVs) to be charged wirelessly while in motion. This method utilizes electromagnetic fields to transfer energy between two coils: one installed in the road and the other in the vehicle. When the vehicle passes over the charging lane equipped with these coils, electricity is transferred, providing power to the vehicle's battery without the need for a physical connection. This innovation has the potential to extend the range of electric vehicles and reduce the need for frequent stops to recharge.

The other options do not facilitate charging while the vehicle is in motion. Battery swapping technology involves exchanging a depleted battery for a fully charged one, which requires the vehicle to stop. Standard wall socket charging involves plugging the vehicle into a power source, which also necessitates that the vehicle remain stationary. Solar panel integration can harness energy while parked or stationary but does not charge the vehicle while it is moving. Thus, inductive charging uniquely enables the continuous transfer of energy, aligning with the concept of charging in motion.
