Abstract

The aim of this project was to build a supercapacitor bank, dc to dc converter, and testing rig to perform efficiency testing for various configurations of the super capacitor bank against various hybrid electric vehicle regenerative braking profiles. A bank of 10 25F cells was constructed along with a bidirectional DC to DC converter allowing practical testing of two of the four possible bank configurations. An average of 55% and 63% end to end efficiency was found for the two configurations respectively when tested under three different scaled regenerative braking profiles. It was found that capacitor banks with a higher maximum voltage i.e. more cells in series were more efficient as there were lower input and output currents and most of losses were restricted to the converter.
