Abstract: The performance of lithium-ion (Li-ion) batteries is highly dependent on their temperature. High temperature accelerates aging by increasing the thickness of the solid-electrolyte interface (SEI) layer, thereby increasing the internal resistance and increasing the safety risk by inducing thermal runaway. Temperature gradients in the cell or in parallel cells can cause inhomogeneous aging in the cell, leading to earlier failure of the battery cell. In addition, the charge acceptance rate to achieve fast charging and extreme fast charging is limited by the temperature rise in the cells. To build safe batteries, it is therefore essential to properly determine the operating temperature of the cell for the battery management system (BMS). In turn, the BMS uses this temperature to implement safety and protection functions as well as charging strategies to maximize battery life. Therefore, this webinar first introduces the effects of temperature on the battery and then introduces the challenges related to the thermal performance of batteries. This is followed by a classification of thermal models that can be used as a guide to select the right model depending on the application. Finally, two practical examples of battery thermal models are presented.
