What is a BEV, and how is it different from an EV, PHEV, and HEV?
- EV (electric vehicle) is an umbrella term for any vehicle driven by an electric motor. A BEV (battery electric vehicle) is a fully electric car powered entirely by its battery and charged from the electricity grid, with no petrol engine. This is the type this calculator is built for. A PHEV (plug-in hybrid) pairs a petrol engine with a battery you can charge from the grid. An HEV is an ordinary hybrid that can't be plugged in; its battery recharges itself while you drive. There are also FCEVs, which run on hydrogen fuel cells. This calculator is for cars you charge from the grid (BEVs, and PHEVs in electric mode), so ordinary hybrids like the Toyota Corolla Cross Hybrid or Nissan Kicks e-Power aren't included.
