Problem

• High Gas Prices
• Hybrid Electric Vehicles (HEVs) not up to par
• Battery is not capable of high power demand

3
Objective

• To design and develop a battery-supercapacitor
  hybrid system

4
Specifications

• 1kW Pulse Load for 18sec every 2minutes
• Lithium Ion battery
• Supercapacitor

5
Design Objectives

• Design a battery to provide the average power to
  the load for at least 20 minutes.
• Design a supercapacitor to provide the pulse
  power to the load.
• Design and build a hybrid structure (or circuit
  configuration) of the battery and supercapacitor
  to provide needed power to the load.
• Design and build a programmable load to simulate
  the pulsating load.
• Test and demonstrate the hybrid energy storage
  system to prove that the constant power is from
  the battery and the pulse power of the load is
  from the supercapacitor.
• Provide final report and suggestions to
  improve/optimize the system
