ECE 480 Fall Semester 2008 Design Team 10 Final Proposal Battery–Supercapacitor Hybrid Energy Storage System Executive Summary: ? The project undertaken by design team?ten is to design and build a “Battery-Supercapacitor Hybrid Energy Storage System” for HEV and renewable power generation. The system will provide optimum energy and power density for HEV and alternative (renewable) power generation. The battery will provide long-term constant power and the supercapacitor will deliver short-term pulse power, to a pulsating load. The hybrid energy storage system will be 48 Volts nominal and able to power a pulsating load with the following characteristics: 48 Volts ( 20%, one kilowatt peak power for 18 seconds over every two minutes with almost 0 kW for the remaining 102 seconds of every two minute period. Our goal is to create an energy storage system that will be able to provide power for at least ten of these cycles over the course of 20 minutes. Due to time constraints, this project will not involve any power generation or regeneration systems. Team ten will construct a digitally monitored and controlled hybrid lithium ion battery – supercapacitor system, and a variable Ohm, one-kilowatt load for testing purposes.
