Description: This infographic compares the energy losses of both ICEVs and BEVs for combined city/highway driving. Engine losses are the biggest for ICEVs at 68-72%. Energy losses for BEV are mostly from battery charging (10%) and electric drive system (20%). BEVs also have regenerative braking which can recover up to 17% of energy to recharge the battery.
