Ultra Compact Cost Effective Fast Charger Stations
Research Project, 2015 – 2017

A fast charger station can charge the vehicle battery in 5-10 minutes but they are very expensive and massive. For instance Terra 53 is a 50 kW fast charger station manufactured by ABB which has a weight of 400 kg and a dimension of 760 mmx525 mmx1900 mm. The cost of these chargers is in the range of half a. Recent advancements in the device developments and design tools enables one to have a higher power density (power divided by volume or mass) chargers that is equivalent to a smaller size and weight. Semiconductors based on Silicon Carbid (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 whish is a considerable reduction in the charger volume, mass and in the long run consequently on the price. 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.
