Induction Charger

Jump to: navigation, search

Induction chargers utilize an electromagnetic field to charge devices wirelessly, without having to be 'plugged in' to a wall. Induction chargers reduce the risk of electric shock from contacting devices that are wall connected, yet typically operate at a lower efficiency, sometimes heating the device to high temperature.

Induction Charging Electric Vehicles

Electric vehicles may be able to utilize what is known as 'induction', or wireless charging. The technology, under research by the company Evatran, would be able to keep a car at full charge overnight. This could avoid the frustration of waking up to use your car only to find it uncharged having forgotten to plug it in the night before. The ease of use would be a huge benefit to electric car users.

The induction charger would be a hub sitting on the garage floor. A vehicle would drive and rest over the hub, where it would enter the induction charger's electromagnetic field. This field would be recognized by a coil in the vehicle, which would convert it to electricity and help store the vehicle batteries at full charge.

Wall to vehicle charging of electric vehicles creates another dilemma: the use of electricity for charging vehicles comes mostly from Coal-fired Power Plants. This is why, currently, efficient diesel-powered vehicles are still much more popular. The induction charger would actually be 10% less efficient that wall charging, wasting much energy, but proponents believe that the peace of mind would force people to buy electric vehicles and spur these same people into investment in wind and solar renewable energy sources.
