BEV

A battery electric vehicle (BEV) is a type of electric vehicle (EV) that uses chemical energy stored in rechargeable battery packs. BEVs use electric motors and motor controllers instead of internal combustion engines (ICEs) for propulsion. A battery-only electric vehicle or all-electric vehicle derives all its power from its battery packs and thus has no internal combustion engine, fuel cell, or fuel tank. BEVs include bicycles, scooters, rail cars, forklifts, buses, trucks and cars. Since the introduction of the all-electric Nissan Leaf in December 2010, over 600,000 highway legal plug-in electric vehicles have been sold worldwide by September 2014, of which more than 356,000 are all-electric passenger cars and light-duty trucks.[2] The best-selling all-electric car ever, the Nissan Leaf, has sold over 147,000 units worldwide by mid-November 2014.[1]

HEV

A hybrid electric vehicle (HEV) is a type of hybrid vehicle and electric vehicle which combines a conventional internal combustion engine (ICE) propulsion system with an electric propulsion system. The presence of the electric powertrain is intended to achieve either better fuel economy than a conventional vehicle or better performance. There are a variety of HEV types, and the degree to which they function as EVs varies as well. The most common form of HEV is the hybrid electric car, although hybrid electric trucks (pickups and tractors) and buses also exist.

PHEV-‐xx

A plug-in hybrid electric vehicle with a particular all-electric range, which is denoted by XX, i.e. PHEV 20 denotes plug-in hybrid with 20 mile all- electric range

EV

An electric vehicle (EV), also referred to as an electric drive vehicle, uses one or more electric motors or traction motors for propulsion. An electric vehicle may be powered through a collector system by electricity from off-vehicle sources, or may be self-contained with a battery or generator to convert fuel to electricity.[3] EVs include road and rail vehicles, surface and underwater vessels, electric aircraft and electrically powered space vehicles.

ICE

An internal combustion engine (ICE) is an engine where the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine the expansion of the high-temperature and high-pressure gases produced by combustion apply direct force to some component of the engine. The force is applied typically to pistons, turbine blades, or a nozzle. This force moves the component over a distance, transforming chemical energy into useful mechanical energy. The first commercially successful internal combustion engine was created by Étienne Lenoir around 1859.[1]

LDV

Light Duty Vehicles includes vans, pickups, and sport utility vehicles

V2G

Vehicle-to-grid: the capability for two-way energy flow and two-way communications between an EV or PHEV and the grid; Communications may be available between the vehicle and the system operator or utility business units, or any external stakeholder

WTW

Well-to-wheel is the specific LCA used for transport fuels and vehicles. The analysis is often broken down into stages entitled "well-to-station", or "well-to-tank", and "station-to-wheel" or "tank-to-wheel", or "plug-to-wheel". The first stage, which incorporates the feedstock or fuel production and processing and fuel delivery or energy transmission, and is called the "upstream" stage, while the stage that deals with vehicle operation itself is sometimes called the "downstream" stage. The well-to-wheel analysis is commonly used to assess total energy consumption, or the energy conversion efficiency and emissions impact of marine vessels, aircraft and motor vehicles, including their carbon footprint, and the fuels used in each of these transport modes.
