The energy content of the supercapacitor bank is twice the regenerative breaking energy of the electric bus at average speed. The electric bus commutes 490 km per charged battery and consumes 400 Wh/km. Design the supercapacitor bank to provide 100V output, based on supercapacitor cells with 3600F capacitance and 2V. Calculate the energy density of the supercapacitor at the cell level, assume cells with 10cm diameter and 15 cm height. 3.
