Automotive Industries (AI) asked Xin Li, Head of the BASF eMobility Innovation Center Asia Pacific, what the thermal management and safety challenges are with solid state batteries (SSBs). At the same time the energy density of the battery pack is getting higher and higher. But even worse is an electric arc inside the battery pack generated by the high-voltage busbar. Ai: How does Welion and BASF next-gen battery pack, improve the competitiveness and environmental credentials of next-generation electric vehicles? Li: The battery pack we have launched together with Welion using our vertical cooling plate has a pack level energy system level density of over 300 Wh/kg, which is roughly 50% more than the conventional battery pack level.
