Abstract :
A novel electrified bicycle using only ultracapacitors as the primary energy storage components are described. A specific buck converter to charge the e-bike in less than two minutes has been designed and simulated. The simulation of the associated fast-charging system shows that this technology is feasible for the intended application. Novel ultracapacitors, made from Carbon Nano-Onion materials, have been produced and the impedance spectra were measured. The data were fitted to an equivalent electrical model and the parameters for the ultracapacitors were determined. It is possible to increase the total viable e-bike distance by 22% by using nanocarbon materials, such as nano-onions, for energy storage.
