- Novel approach based on Sheet Molding Compounds (SMC) for high voltage battery module housings
- Semi-integral vehicle integration approach to meet requirements for future vehicle architectures
- Superior performance, fast charging capabilities and great sustainability at reasonable costs
Baar (CH), March 08, 2022 – LION Smart GmbH, VESTARO GmbH, Evonik, Forward Engineering GmbH, together with Lorenz Kunststofftechnik GmbH and Minth GmbH have developed a new generation of battery packs – the Pure Performance Battery (PPB) – for battery electric vehicles (BEV) based on Sheet Molding Compound (SMC) technology. The new holistic battery system concept offers a safe, lightweight, and most importantly cost-effective alternative to the heavier metal-based solutions for the automotive industry.
VESTARO, with access to Evonik’s curing agents portfolio and expertise in tailored composite-matrix systems, kicked-off the project to investigate alternative battery solutions at the end of 2019. The results of the first developments were presented at the beginning of 2021. Afterwards the automotive TIER 1, Minth GmbH, joined the consortium to improve the structure even further, with their in-depth know-how for aluminum solutions.
LION Smart provides fast chargeable immersive cooled module concept for Pure Performance Battery
The Pure Performance Battery utilizes LION Smart’s immersive cooled module concept to create a cost-effective, lightweight and high voltage cell to pack system. Individual cells are enclosed in a non-flammable dielectric coolant. This also ensures a constantly low average temperature within the battery which benefits cell aging.
The modular series design of the battery also allows flexible adjustment of the number of modules with an extremely low overall height. The supercell concept based on LION Smart’s LIGHT Battery enables a calculated fast charging result around 13 minutes for charging power constantly above 200 kW (10 % – 80 % SOC). The system is currently developed to achieve a charging time of less than 10 minutes.
Delivering superior performance, safety and sustainability features to customers
The whole battery pack is designed for performance. The unique Epoxy-SMC cover is manufactured by Lorenz Kunststofftechnik and provides an outstanding safety potential in terms of fire resistance and crash behavior. It could sustain all relevant fire related test set-ups including thermal runaway tests.
Using Forward Engineering’s unique BEV-floor structure development tool, the new Pure Performance Battery is suitable for a variety of vehicle architectures. In terms of weight, the new glass fiber (GF)-SMC cover-based battery competes with today’s high-end solutions but delivers a significant increase in performance.
Thanks to the in-depth aluminum knowledge of Minth GmbH, it was possible to increase the capabilities even further. The newly developed bottom structure made from extruded aluminum profiles has a key role in the new structure concept. It delivers a high-end bottom impact performance and connects the side rockers of the car to build the load caring path together with the vehicle’s seat-crossmembers in case of an impact.
In addition, the Pure Performance Battery provides great benefits in terms of sustainability as the cover can be demounted via unscrewing several screw-joints to enable an easy access to battery modules and peripheral equipment. The cover itself can be recycled via LORENZ Kunststofftechnik’s unique recycling process and used afterwards in new composite parts.
