On-board chargers are the great equalizers for electric vehicle charging — and can be a game-changer for the future of e-mobility. Fraunhofer IZM has managed to bring together some of the most innovative ideas in power electronics to pave the way for a new generation of on-board chargers. Twice the performance at half the size, bidirectional capabilities, and efficiently machine-made: The resulting on-board charger is the economical ticket to the fast lane into the future.

The smart packaging and interconnection techniques employed by Fraunhofer IZM finally allowed the Institute to create an OBC that is a mere three cubic decimeters in volume: half the size of conventional OBC, but with double the charging capacity at 22 kW. “In essence, we are just working with one big circuit board. Our packaging solutions mean that we can have a machine fit everything we need on this board,” Oleg Zeiter says. In practice, this means a major reduction in production cost.
