Zusammenfassung
Market analysis are clearly showing increased electrification of powertrains. In 2030, Battery Electric Vehicle (BEV) market share could be as high as 30-40 %. Among the different challenges for developing a battery pack for HEV and BEV, the cooling method can account for up to 7 % of the total cost of the battery pack as well as impacting weight and packaging volume. With the forecasted cost reduction of the battery cell, the required increase in power density and energy density, the cooling method plays an even greater role. The paper will present the methodology used to develop battery immersion cooling solution which is an innovative cooling method to enable Ultra-Fast Charging (UFC) (> 350 kW). It is also highlighting the impact at vehicle level and the mitigation of thermal runaway analysis to support battery development.
