Two-phase evaporative battery thermal management technology for EVs/HEVs: theory and control

Electrical vehicle needs to draw power from battery for acceleration. It needs to draw high current for speeding up to 130 km/h on 0% gradient and 40 km/h on 5-10% gradient. Battery generates powerful electrical currents to meet the power demands of EV, causing significant warming of the Li-ion cell...
