All-electric vehicles (AEVs) can function only with electrical energy. It does not need a combustion engine, guaranteeing an ecologically friendly drive. Instead, it runs thanks to the energy provided by its electrical network through a recharge site. Its range is limited to 130 to 400 kilometres because of the batteries. Nevertheless, some new models allow for distances of over 400 km.
Plug-in hybrids combine the internal combustion engine (diesel or gasoline) with an electric motor and batteries that can be recharged by connecting the vehicle to the power supply system. This is the main difference with the traditional hybrids that do not plug in. Conventional hybrids depend on regenerative braking to feed power back into the batteries and the excess energy produced by the motor. As a result, the electric range is superior to that of the non-plug-in hybrids, lowering its emissions level. It also has a regenerative braking system. The electric range is between 15 and 50km when operating solely in electric mode.
An extended-range electric vehicle is an AEV where the combustion engine (diesel or gasoline) powers the electric motor’s batteries. It is important to emphasize this is not a hybrid. The combustion engine is not used for propulsion but to charge the batteries, thus achieving a wider range. An extended-range electric vehicle has a support generator for recharging the batteries. It is a vehicle with two motors. The conventional combustion engine recharges the batteries on the go for the electric motor, allowing the EV to move with a constant source of electricity. This technology extends the range up to some 80 km in electric mode.
