Battery-Supercapacitor Hybrid System Design Team Ten Final Presentation ECE 480 FS08
Objective To design and develop a battery-supercapacitor hybrid system KELD, LLC Team 10
Specifications 1kW Pulse Load for 18sec every 2minutes Lithium Ion battery Supercapacitor KELD, LLC Team 10
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 KELD, LLC
Design Objectives Completed Constructed 14 Cell Battery Pack Lithium Polymer 3.7 Volts per Cell Program Control Module Obtained a 165F Supercapacitor Max Voltage: 48V Obtained 4 Millennium3 relays Obtained 2 Heat Sinks KELD, LLC Team 10
Design Objectives Completed Constructed Battery-SuperCapacitor Hybrid System Tested the system KELD, LLC Team 10
Design Improvements Design more robust battery pack Attach a movable load Better container Better relays Circuit Protection KELD, LLC Team 10
Future Applications Add Sensors Voltage/Current Display Automobiles Cell phones Computers KELD, LLC Team 10
