“…The temperature of each cell inside the battery pack varies, depending on the battery pack's design. Temperature variations may lead to over-charge or over-discharge during cycling which further contribute to premature failure in the battery packs in the form of accelerating capacity fading or thermal runaway [3,4].…”

This research is about an experimental study of battery temperature under constant discharge rate. This study consider constant discharge rates, constant air velocities, gap between battery cells in the battery module and placement of Resistance Temperature Detector (RTD) sensors to achieve the objective of this experiment studies. The relationship of temperature and discharge rates for different point on battery cell surface is compared. The Lithium-ion battery cells are discharged with a constant discharge current in this experiment. The heat generation on the battery surface as a function of discharge time are linked to the LabVIEW software. An axial fan creates constant air velocities that help in removing heat away from battery module during discharge process. The factors that are considered in this experiment are the discharging rate, air velocities and the thermal behaviour of the Lithium-ion battery cell on various point across the battery surface.

“…Temperature is one of the most important parameters of a lithium ion battery that needs to be attentively controlled, owing to the optimal working condition is generally limited between 20 and 65 °C (1,2). Additionally, the battery's functioning temperature remarkably influences the battery's lifetime, cell degradation and efficiency.…”

“…Temperature is one of the parameters of a lithium ion battery that has to be carefully controlled, because the optimum working range is typically limited between 20 and 65 °C . Furthermore, the battery's working temperature greatly influences efficiency, cell degradation, and the battery's life time.…”

“…Temperature variations may lead to further differences in impedance, thus amplifying the capacity imbalance among the cells that causes the disadvantaged cells to be over‐charged or over‐discharged during cycling . This is the major contribution to premature failure in the battery packs in the form of thermal runaway or accelerating capacity fading . The battery management system (BMS) supervises individual cells in order to improve the battery pack performance and decrease risks.…”

International audienceThis article presents an electro-thermal model of a stack of three lithium ion batteries for automotive applications. This tool can help to predict thermal behaviour of battery cells inside a stack. The open source software OpenFOAM provides the possibility to add heat generation because of Joule losses in a CFD model. Heat sources are introduced at the connectors and are calculated as a function of battery discharge current and internal resistance. The internal resistance is described in function of temperature. Simulation results are validated against experimental results with regard to cooling air flow field characteristic and thermal behaviour of the cell surface. The validation shows that the simulation is capable to anticipate air flow field characteristics inside the battery box. It also predicts correctly the thermal behaviour of the battery cells for various discharge rates and different cooling system conditions. The simulation supports the observation that batteries have a higher temperature close to the connectors and that the temperature increase depends highly on discharge rate and cooling system conditions.
