LION E-Mobility AG: Consortium of companies develops more cost-effective and lighter battery concept for e-mobility - Seite 2

For the battery housing, Lorenz developed a new glass-fiber-reinforced epoxy sheet molding compound (SMC) using Evonik's VESTALITE(R)S epoxy hardener, with excellent properties in terms of bending, impact, and fire resistance. The structure of the housing was realized by Vestaro with a bottom plate made of aluminum. Transversal beams are used to attach the battery modules, and the carrier plate for the battery management system is also fixed to the aluminum base.

Validation and series suitability of the battery concept

To verify the suitability of the material and the manufacturing process for series production, Lorenz also produced several complex hardware demonstrators. Safety and suitability for everyday use of the battery concept were extensively tested by Forward Engineering under real conditions within the framework of structural and safety-related simulations. Various configurations of the battery concept have already been realized. Three energy configurations are currently available:

- 65 kWh at a total weight of 412.1 kg

- 85 kWh at 527.3 kg

- 120kWh with 800V at 789.2 kg

In terms of energy density, safety and cost, the three energy configurations are at least on a par with current battery models on the market and even surpass them in specific metrics.
