EVs (all-electric vehicles) are powered only by one or more electric motors. They receive electricity by plugging into the grid and store it in batteries. They consume no petroleum based fuel while driving and produce no tailpipe emissions.
EVSE (electric vehicle supply equipment) deliv-ers electrical energy from an electricity source to charge a PEV’s batteries. It communicates with the PEV to ensure that an appropriate and safe flow of electricity is supplied.
HEVs (hybrid electric vehicles) combine an ICE or other propulsion source with batteries, regenerative braking, and an electric motor to provide high fuel economy. They rely on a petroleum-based or alternative fuel for power and are not plugged in to charge. HEV batter-ies are charged by the ICE or other propulsion source and during regenerative braking.
ICEs (internal combustion engines) generate mechanical power by burning a liquid fuel (such as gasoline, diesel, or a biofuel) or a gaseous fuel (such as compressed natural gas). They are the dominant power source for on-road vehicles today.
PEVs (plug-in electric vehicles) derive all or part of their power from electricity supplied by the electric grid. They include EVs and PHEVs. PHEVs (plug-in hybrid electric vehicles) use bat-teries to power an electric motor, plug into the electric grid to charge, and use a petroleum based or alternative fuel to power an ICE or other propulsion source.
