Conventional Hybrids combine both an internal combustion engine with an electric motor, however they are not primarily fueled by electric. The battery is charged through regenerative braking, where energy is captured and turned into electricity when braking. They do not utilize plug-in charging and are not included as part of the Collaborative.
The two primary types of plug-in electric vehicles are battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs). PHEVs similar to conventional hybrids, are made up of an ICE engine and electric motor. However, PHEV batteries can be charged by plugging into an outlet, providing the vehicle a limited electric range. When the battery range is depleted, the ICE engine takes over. BEVs only utilize an electric motor and run solely on electricity from the grid by plugging into an outlet or charging station, replacing gasoline entirely.
