With increasing demand for electric (EV) and hybrid electric (HEV) vehicles, a longer lifespan battery for vehicle application has become more desirable. The lifespan of these batteries are largely dependent on their type of usage in various environmental conditions, such as current demand, discharge and charging rates, and temperature. In addition, it is essential to monitor the heat generation produced in batteries to prevent the development of “hot spots” in battery packs, shortening their lifespan. This research addresses this important idea to characterize both electrical performance and heat generation by developing an experimental methodology for thermal and electrical characterization of Li-Ion battery cells used for EV and HEV application. A set of tests have been developed using an isothermal battery calorimeter to characterize heat generation of Aged and Non-Aged Li-Ion battery cells at various charge/discharge rates. The outcome of this research will be fundamental to understanding long term degradation phenomena on electrical and thermal outputs of cells, and develop models to characterize the heat generation and temperature variation in battery cells.
