Power Up Without a Plug

A Virginia company called Evatran has debuted their prototype for an EV charger that works without plugs, cables or a flow of electricity between the vehicle and the charger. This new charging system doesn’t work by magic, but by induction.  To recharge an EV with this system, the vehicle pulls up to the charging station and parks over a floor-mounted parking block.  An adapter fitted to the vehicle and the parking block both contain metal coils that become aligned by magnetic sensors.  The control tower for the charging station converts electricity into the right frequency for the charger and when the coils are aligned, the electricity creates a strong magnetic field in the parking block’s coils that induces a flow of electricity in the coils in the vehicle’s adapter, which charges the battery.
