There are 3 basic types of EVs: battery EVs, plug-in hybrid EVs and hybrid EVs. Battery EVs use on-board electric motors alone. Hybrid EVs use a conventional internal combustion engine and an electric drive. Currently, there are 3 charging levels available each with varying charging efficiencies. Networked EV chargers feature an internet connection and use a management system with the ability to stop, start, delay and monitor charging remotely. Non-networked chargers do not feature an internet connection and do not have any kind of use-management system.
