Electric vehicles (EVs) and hybrid vehicles (HEVs & PHEVs) are becoming increasingly prevalent to reduce the environmental detriments produced by traditional combustion engine (ICE) vehicles. The use of stored electrical energy as opposed to stored chemical energy (gas) requires the use of large battery packs to supply the electric drivetrain, and therefore the electric … [Read more...]
