Toolkit for Steel-based High-voltage Battery Housings
- 1 Downloads
The high-voltage battery housing is currently a development focus of numerous OEMs and suppliers and is often made of aluminum. A single solution for all application purposes does not seem to make sense due to differentiated requirements. However, steel can be a promising material to increase safety and reduce costs. fka and voestalpine have therefore investigated in a joint project how a technology toolkit for steel-based high-voltage battery housings should be designed.
High Share of Added Value
The high-voltage battery is currently in the focus of attention in the development processes of battery electric vehicles due to its high share of added value with respect to the overall vehicle as well as its great technological potential. In addition to cell development, which takes place in isolation from the vehicle, the focus is on improving mechanical properties and thermal cell conditioning of vehicle systems. These aspects are determined in particular by components of the battery...
