Electrochemical capacitor and battery are electrochemical energystorage system. The former has a very good power density (fastcharging/discharging) but low energy density, while the latter hasthe opposite properties. Please design a device that can have goodpower density and energy density by combining the electrochemicalcapacitor and battery. Please provide an equivalent circuit (use-||- to represent capacitor and -©- to represent battery) todescribe your design and how they work under charging/dischargingconditions. You can use multiple battery and capacitors for yourdesign and explain how it work. Do you think your design can beused to power an electric vehicle to compete with gasoline-basedcars?
