Battery supercapacitor hybrid system

1. Team 10:
Battery Supercapacitor
Hybrid System
KELD LLC

2. 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

6. Design Objectives Completed
