Although the number of electric vehicles and plug-in hybrid vehicles worldwide has reached millions, related parts and components still lack common specifications. At present, all parties are working hard to promote the standardized management of vehicle components and establish cross-market component standards.
How to expand the battery capacity and improve the efficiency of kinetic energy recovery, thereby extending the cruising range of electric vehicles, is a major topic of great concern at the moment. In addition, reducing the weight of vehicle components can also help reduce driving resistance (such as rolling resistance, uphill resistance, acceleration resistance), thereby reducing energy consumption.
To this end, Evonik has joined hands with Forward Engineering, LION Smart, Lorenz Kunststofftechnik and Vestaro (a joint venture between Evonik and Forward Engineering) to develop modular multi-material technology since the end of 2019, and recently launched a brand Power battery housing solution with good compatibility and high cost-effectiveness. Compared with other commonly used material combinations, this solution can reduce the weight of the battery case by about 10% without any loss of mechanical properties.
This solution is suitable for batteries of 65 kWh, 85 kWh and 120 kWh, and can be adapted to a variety of vehicle sizes. Among them, the battery case is made of glass fiber sheet molding compound (SMC), and Evonik’s VESTALITE® S high-performance epoxy curing agent is also used. The performance level of the battery case is equivalent to that of the traditional metal-based battery case, and at the same time, the weight is greatly reduced compared with the existing SMC battery case with higher cost.
