Fluctuating solar and wind power require lots of energy storage, and lithium-ion batteries seem like the obvious choice—but they are far too expensive to play a major role.
According to the preferred energy source, pure electric vehicles can be divided into 3 categories: BEVs, FCEVs, and FCHEVs. BEVs rely on electricity stored in large batteries, which are charged through external electric grids while FCEVs use hydrogen FCs to generate electricity onboard.
The demand for electrical energy and power supplies is burgeoning in all parts of the world and large-scale battery energy storage is becoming a feature of strategies for efficient operation.
