EE & CPE 1 - Programmable Battery Cycler


Student Team: Aaron Manry, Jared Graham, Spencer Hand, Ryan Sumpter
Advisor: Dr. Grigore Braileanu
Sponsoring Organization: Commuter Cars
Liaison: Rick Woodbury

    Commuter Cars designs and manufactures electric cars which rely on advanced lithium-ion battery technology. provide the highest quality product, numerous cell characteristics must be known, including how the discharge rate, temperature, and cycle depth affect the cycle calendar life of the battery. characteristics are not supplied by battery manufacturers, so independent research must be done to attain them.
    Our group was responsible for designing a device which charges and discharges battery cells while simultaneously recording current, voltage, and temperature.The data can then be used to identify trends and ultimately gain a more complete understanding of how different driving characteristics affect the battery cells.
