MAHLE Pushes New Battery Casing To Reduce Electric Vehicle Weight/carbon Dioxide Emissions

- Sep 17, 2019-

According to foreign media reports, a key factor in the popularity of electric vehicles is the need to have sufficient cruising range. MAHLE does not use a larger battery to achieve this, but instead introduces a newly developed, integrated heat. The battery compartment for management functions. This solution improves the battery's fast charging capability and reduces the size of the power battery by 40%. Therefore, this solution can not only reduce the carbon dioxide emissions of electric vehicles, but also reduce the raw material demand for battery production, knowing that battery materials worldwide are becoming scarcer.

Dr. Otmar Scharrer, Head of R&D and Senior Engineering at MAHLE, explained: “Our new battery casing concept makes electric vehicles more economical and environmentally friendly. The battery casing is cost-effective to produce, but also a low-cost but powerful battery. It is conducive to pushing affordable electric vehicles to a wider market."

In order to achieve a high level of cooling performance during rapid battery charging, in the MAHLE battery housing concept, the battery is encapsulated by a dielectric fluid. The battery case is made of fiber-reinforced plastic and is not only lightweight but also very strong. Since the battery can be realized in a smaller size, the electric vehicle can also achieve weight reduction.

Cooling batteries and electronic components requires complex circuitry that greatly increases the requirements for individual components and thermal management control systems. From the outset, MAHLE has supported the electrification of power systems and the more stringent requirements associated with them, and has been expanding its expertise in research and development.
