Abstract:
This study was conducted to establish a reliable thermal analysis methodology for
the battery module designed for micro-mobility. Analysis and experiments were
performed first with a single cell and subsequently with a battery module
consisting of 80 cells. The heat generation calculated from a single-cell
experiment and realistic thermophysical properties were used in the module
analysis to predict the temperature rise and distribution at various discharge
rates. A prototype battery module was then built and ten thermocouples were used
to measure temperatures at various locations in the module. Good correlation was
achieved between the analytical results and experimental data. In particular,
the model is accurate in predicting temperature distribution and the locations
of peak temperatures. As a next step, the analytical methods developed in this
study will be used to optimize the battery pack design and enhance its thermal
performance.
