Transcript of Design Team Ten Final Presentation ECE 480 FS08. Overview.
Specifications 1kW Pulse Load for 18sec every
2minutes Lithium Ion battery Supercapacitor
Team 10KELD, LLC
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
