Mild Hybrid (mHEV).
A mild hybrid vehicle is powered by an internal combustion engine that supplies energy to an electric motor. The latter can store the energy and use it in suitable situations. This ensures a saving of up to one litre per 100 kilometres. Each mild hybrid has a lithium-ion battery to store energy. The energy comes from existing start/stop systems or also from brake power regeneration. By the way, mHEV stands for Mild Hybrid Electric Vehicle.
Full Hybrid (sHEV).
A full hybrid has a combustion engine and a battery-powered engine. At low speeds of up to 50 km/h and on short distances of up to approx. 3 km, a pure electric drive is possible. The electricity required to operate the electric motor is generated by the combustion engine. By the way, sHEV stands for strong Hybrid Electric Vehicle.
Plug-in Hybrid (PHEV).
This is like a full hybrid, the difference being that a plug-in hybrid vehicle can drive higher speeds (up to 130 km/h) and longer distances (approx. 40 km) using only electricity. The combustion engine charges the battery if there is not enough power. The battery can be charged via an external power supply unit. By the way, PHEV stands for Plug-In Hybrid Electric Vehicle.
Electric Vehicle with Elektrofahrzeug mit Range Extender (E-REV).
Battery-powered vehicles with an additional small combustion engine and generator are called range extenders. The combustion engine only starts to generate additional electricity for the battery. Unlike the hybrid drive, however, it does not drive the vehicle directly. E-REV stands for Electrical Vehicle with Range Extender.
Battery Electric Vehicle (BEV).
An all-electric vehicle is powered exclusively by a battery-operated electric motor, which is charged via the power grid, i.e. it does not require any fossil fuel. This means that, locally, the vehicle is 100% emission-free. BEV stands for Battery Electric Vehicle.
Fuel cell electric car (FCEV).
A fuel cell car is powered exclusively by an electric motor. Unlike the all-electric vehicle, the electricity is not generated with batteries, but with hydrogen fuel cells. Hydrogen fuel cells generate electricity by combining hydrogen with oxygen. A car with a fuel cell is also 100% emission-free locally. FCEV stands for Fuel Cell Electric Vehicle.
