Mild-Hybrid (MHEV)
Small electro-motor — a big increase in efficiency. No purely electric range.
A cost-effective entry is offered by vehicles with mild-hybrid drive in the electric mobility world. Two synergetic energy sources are provided, a conventional combustion engine and a battery-powered electric motor.
But the vehicle is not driven with an electric motor whereas efficiency is significantly increased.
Hybrid (HEV)
It is a combination of electric and conventional energy which is very ideal. Pure electric drive with short-range.
Two energy sources are provided within the vehicle, an internal combustion engine, and an electric motor. As compare to mild-hybrid vehicles, for short distances, vehicles can switch automatically between internal combustion and electric drive or the vehicle can use both powers when needed.
Plug-in-Hybrid (PHEV)
Plug it, Charging, and finish. Medium range up to approx. 50 km2 with purely electric drive.
The vehicle is equipped with two energy sources. Nonetheless, a larger high-voltage battery is available where the vehicle is enabled to drive purely electrically over longer distances.
Fully electric (BEV)
100% electric. Simply charge and drive off.
All-electric vehicles are exclusively powered by electricity. It leads to the conclusion that the vehicles need to be charged before driving.
Full range up to 600Km2 for modern models.
