Battery concept promises charging in 90 seconds
The automotive supplier Mahle has presented a lithium-carbon battery concept that is supposed to enable ultra-fast charging of light two-wheelers in less than 90 seconds. Smaller vehicles, such as those used for urban distribution, should also be able to be equipped with it - the concept is not (yet) suitable for larger passenger cars.

The battery concept presented does not require any rare raw materials and is fully recyclable. According to the technology supplier, this meets the changing requirements for sustainability.

The battery concept presented as a pre-prototype is intended to combine the advantages of supercapacitors and conventional lithium-ion batteries. The lithium-carbon battery technology not only enables ultra-fast charging, but at the same time offers a high power density and is not susceptible to so-called thermal runaways, in which uncontrolled overheating occurs.

The lithium-carbon battery concept was presented at an expert colloquium in Aachen. At the event, Mahle also presented an integrated thermal management system for battery electric vehicles. With this, the manufacturer wants to optimise efficiency at the system level, reduce costs and enable the integration of engine, electronics and battery temperature control into the overall system.
