Mahle said it had developed an EV battery housing with integrated thermal management as a solution for increasing the rapid charging capability of the battery.

This allows traction batteries to be about 40% smaller and thus recharged very quickly. This reduces the CO2 footprint of the electric vehicle and also lowering the demand for raw materials for battery production which are becoming increasingly scarce worldwide.

To implement the required high cooling performance during the rapid charging process, the battery cells are surrounded by dielectric fluid as part of the battery housing concept. The fibre reinforced plastic design is lightweigh and also extremely robust. The concept also provides massive weight benefits in the vehicle due to the smaller battery.

The need to cool batteries and power electronics gives rise to complex circuits that substantially increase the requirements on individual components and thermal management control systems.

Mahle has supported the growing electrification of the powertrain and the associated tougher requirements from the start and is continuously expanding its expertise in research and development.
