Prius Hybrid Battery and Combustion System
There are a lot of EV-related terms with acronyms that make discussing them a simpler process, that is, if you know the lingo…
ICE – Internal Combustion Engine: often used to refer to conventional vehicles with ICE that use emissions-producing fuel such as gasoline.
EV – Electric Vehicle.
Hybrid or HEV – Hybrid Vehicle which has a combustion engine and electric battery: the combustion engine recharges the electric battery.
PHEV – “Plug-in” Hybrid Electric Vehicle: similar to an HEV, but allows for recharging the battery through an electric plug.
BEV or PEV – Battery or “Plug-in” Electric Vehicle: all electric, runs and charges fully electrically.
EVSE – Electric Vehicle Supply Equipment: equipment in an infrastructure that supplies electricity for charging of electric vehicles.
EREVs – Extended Range Electric Vehicle: operates as a battery electric vehicle for a certain number of miles. After the battery has been discharged, a gas engine powers an electric generator for several hundred miles of ‘extended-range’ driving.
kW – Kilowatt: unit of energy.
kWh – Kilowatt-Hours: the fuel efficiency of an all-electric vehicle may be measured in kilowatt-hours (kWh) per 100 miles rather than miles per gallon. To calculate the cost per mile of an all-electric vehicle, the cost of electricity (in dollars per kWh) and the efficiency of the vehicle (how much electricity is used to travel 100 miles) must be known. If electricity costs $0.11 per kWh and the vehicle consumes 34 kWh to travel 100 miles, the cost per mile is about $0.04.
MPGe – Miles Per Gallon (of Gasoline) Equivalent
ZEV – Zero-Emission Vehicle: vehicle that produces no emissions from the on-board source of power.
FCEV – Fuel Cell Electric Vehicle: vehicles that convert the chemical energy from stored hydrogen and oxygen in the air, into electricity to power an electric motor.
