VEHICLE TYPES
Types of electric vehicles Since electric cars differ in terms of functionality and construction, depending on driving behavior, different models are worth considering. Pure electric cars, range extenders and the plug-in hybrids are the most conven- tional types. The structure and the essential differences between these electric vehicle models are shown below.
THE PURE ELECTRIC CAR (BEV) Pure electric vehicles, which are also called BEVs, an abbreviation of Battery Electric Vehicle, have only an electric motor installed. The BEV obtains the energy required for the drive from an energy source directly in the vehicle, the battery. This is charged via the power grid and stores the recovered braking energy during recuperation.
RANGE EXTENDER (REEV) Range Extended Electric Vehicles (REEVs) are electric vehicles that, in addition to the battery, are also equipped with an internal combustion engine, the so-called range extender. In contrast to PHEVs, this additional motor does not drive the vehicle directly, but only supplies electricity for the battery. The following mechanism is used to ensure that the vehicle does not come to a standstill due to an empty battery while driving: The range extender is activated automatically as soon as the battery status is low and keeps it constantly low due to the charging current while driving. REEVs are offered by some car manufacturers because battery technology is currently still expensive.
