Ultra Compact Cost Effective Fast Charger Stations

The aim of this project is to design, simulate, implement, verify an ultra-compact cost effective fast charger station with a power level of 50 kW and demonstrate the latest technological improvements in device and materials.

A fast charger station can charge the vehicle battery in 5-10 minutes. However, they are very expensive and massive, the cost being in the range of half a million sek. Recent advancements in device developments and design tools enables  a higher power density charger with a smaller size and weight. Semiconductors based on Silicon Carbide (SiC), magnetic materials based on Nanocrystallin and modern design tools like FEM simulators are examples of these advancements. In the new designs the power density can be as high as 1 kW/Liter which is a considerable reduction in the charger volume, mass and in the long run consequently on the price.

The implemented charger has a performance index slightly above the state of the art that is mainly due to using new device and materials.

Chalmers University of Technology, Göteborg Energy, Vattenfall, Vaccume Schmeltz, and Saab Aero. The project is conducted within the framework of SHC.

The project is mainly financed by the Swedish Energy Agency.
