BEV, HEV, PHEV – abbreviations for electric cars can be confusing for those who have just stepped into the world of battery-powered vehicles. What distinguishes the types of electric cars are the principle of operation and the degree to which they emit harmful gases, and all of them have in common that, to a greater or lesser extent, they protect the environment.
At the mention of electric vehicles, most will first think of cars with exclusively electric drive. BEV vehicles (Battery Electric Vehicle) do not use fossil fuels and have zero emissions, and the only source of energy that drives the engine is a lithium-ion battery.
However, hybrids have been available to drivers for some time now, as the name suggests, combining electric drive with conventional fuel propulsion.
Hybrid electric vehicles (HEVs), or just hybrids, have a battery that powers the electric motor, but also a tank of gasoline or diesel to start the SUS engine. However, these hybrids do not have a connector that would allow charging the battery at an external source such as a charger or home outlet, so the only option for charging the battery is regenerative braking or SUS engine operation.
Regenerative braking works on a simple principle: collect as much energy as possible that is wasted during braking and convert it into electricity that is stored in the battery, writes Autocentarforma.
On the other hand, plug-in hybrids (PHEVs) are equipped with a larger battery compared to standard hybrids, and they also have a plug so that they can be charged on a socket or charger. Thanks to the larger battery, driving plug-in hybrids is possible in fully electric mode for an average of up to 50 km (although the BMW i3 can cover as much as 200 km), while carbon dioxide emissions are lower compared to HEV. However, the higher battery life and technical complexity make PHEV models heavier and more expensive compared to standard hybrids.
