Below are some terms that are used in this industry:
BEV - Battery Electric Vehicle An EV that does not have a combustion engine at all, rather it relies solely on a battery system and must be plugged into a charging source to replenish the charge
EVSE - Electric Vehicle Supply Equipment The "charging" equipment used to maintain a charge on EV battery systems
HEV - Hybrid Electric Vehicle An EV that combines an internal combustion engine with an electric propulsion system. The charge on the batteries is maintained through regenerative energy from braking and from other onboard power sources (such as an internal combustion engine)
J1772™ The North American (and Japanese) adopted SAE standard for the design of the Charge Coupler (a pin and sleeve device)
PEV - Plug-in Electric Vehicle Any motor vehicle that can be recharged from an external source of electricity. The electricity is stored in rechargeable battery packs and either drives or contributes to driving the wheels
PHEV - Plug-in Hybrid Electric Vehicle An HEV that incorporates a separate battery system where the charge is maintained by plugging into an external power source
Level 1 EVSE - 120 Volt Charging Equipment Can fully charge an all-electric vehicle in about 18 hours. A plug-in hybrid may charge to capacity in as little as six hours depending on the capacity of the battery pack
Level 2 EVSE - 240 Volt Charging Equipment Similar to what is used for a clothes dryer, and is well suited for more quickly charging PEVs. Charging time is approximately three to eight hours, depending on vehicle type
Level 3 EVSE - High Voltage Charging Equipment While not formally defined, commonly known as fast or rapid charging and requires high levels of voltage and current to replenish more than half of an EV's battery capacity in as quickly as ten minutes
