To answer one of the biggest demands from EV owners, Mahle has developed a completely new cooling system for batteries to enable them to charge faster.
Cooling is a major challenge, especially when it comes to fast charging battery-powered electric vehicles. The Stuttgart-based specialist for thermal management, i.e., the heating and cooling of the vehicle interior and components supplier relies on immersion cooling as a key technology. An electrically nonconductive coolant flows around the cells, thereby ensuring that the maximum temperature of the battery drops markedly during charging and that the overall temperature is distributed much more homogeneously. Immersion cooling shortens the charging times in electric cars considerably. The batteries can thus be smaller, making electric cars cheaper and more resource-efficient. With this technology, Mahle is making a further contribution to faster market penetration and broader acceptance of battery-powered e-mobility by consumers.
“Immersion cooling paves the way for a whole new generation of battery systems,” says Martin Berger, Vice President Corporate Research and Advanced Engineering at Mahle.
Mahle is transferring its expertise in plastics, thermal management, and power electronics into new integrated solutions. The technology group is thus focusing on the areas where e-mobility still needs a boost—charging speed, range, resource conservation, and price.
