Custom Battery Module Test Fixture with strings of three batteries connected serially and four strings in parallel to form a battery pack of 12 Li-ion batteries to achieve a nominal voltage of 13.2 volt. This pack is designed for research into battery management systems for electric and hybrid vehicles.


Peltier Device controlled with special-purpose controller to test the battery characteristics under different temperature conditions. The controller software also serves as an educational tool in instructing PID tuning and controller techniques.


Cycling Station consisting of two programmable loads and a two channel power supply, with automated testing software all integrated into a Linux server to provide a stable testing environment. Automated testing software is a Labview based program which takes individual battery characteristics as parameters so that different testing procedures of charging and discharging can be implemented.


Voltage measurements of individual battery cells is taken after running the battery pack under multiple charging and discharging cycles to observe the behavior of each cell. This is done through the isolation amplifier circuit and is recorded using the NI Data Acquisition Card.


Current measurements of individual battery cells is taken after running the battery pack under multiple charging and discharging cycles to observe the behavior of each cell. This is done through the Dataforth Module and is recorded using the NI Data Acquisition Card.


Temperature Control Chamber allows the batteries to be tested at different temperatures.


Various pack configurations are possible via custom hardware.
