Vehicle types

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 halt 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.

Plug-in hybrid vehicle (PHEV)

Since hybrid vehicles (HEV = Hybrid Electric Vehicle) have an electric motor and internal combustion engine installed at the same time, they combine conventional and electric drive systems. With HEVs, the battery is charged via the internal combustion engine or the regenerated braking energy (recuperation). Plug-in hybrid electric vehicles (PHEVs) are vehicles that use a battery that can be charged directly from the electricity grid. A great advantage of hybrid vehicles is that they can cover shorter distances only using electricity and can also cover longer distances. As the battery tech- nology is constantly being developed, an increase in the electrical portion is expected in the future.

Hybrid vehicle (HEV - Hybrid Electric Vehicle)

A hybrid is a vehicle that is equipped with an internal combustion engine and an electric motor. There are differences in construction and hybridization. In general, the electric motor supports the combus- tion engine especially when starting up, when the engine has poor efficiency. This means that fuel con - sumption can be reduced by 15-25%. The difference between a classic hybrid and a plug-in hybrid is that a full hybrid can only be operated electrically over very short distances.
