A key factor in the popularity of electric vehicles is the need for sufficient range. MAHLE did not use a larger battery to achieve this. Instead, it introduced a newly developed battery shell with integrated thermal management functions. . This solution can improve the battery's fast charging capacity and reduce 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 demand for raw materials for battery production. It is important to know that battery materials are becoming increasingly scarce worldwide.
Dr. Otmar Scharrer, Head of R & D and Senior Engineering at MAHLE explains: "Our new battery case concept makes electric vehicles more economical and environmentally friendly. The battery case is moderately cost-effective to produce, but also enables a cheap but powerful battery , Which will help bring affordable electric vehicles to a wider market. "
In order to achieve a high level of cooling performance during fast battery charging, in the MAHLE battery case concept, the battery is wrapped with a dielectric fluid. The battery case is made of fiber-reinforced plastic, which is not only lightweight but also very sturdy. The ability to achieve smaller batteries also allows electric vehicles to achieve weight reduction.
Cooling batteries and electronic components requires complex circuits, greatly increasing the requirements for individual components and thermal management control systems. MAHLE has supported the electrification of powertrains and the more stringent requirements associated with them from the beginning, and has been expanding its R & D expertise.
