1D-Thermal Analysis and Electro-Thermal Modeling of Prismatic-Shape LTO and NMC Batteries (original) (raw)

2019, 2019 IEEE Vehicle Power and Propulsion Conference (VPPC)

In order to accurately predict and optimize the thermal behavior of batteries, a thermal model using heat equation and thermal parameters, such as the specific heat capacity, is developed. The specific heat capacity is an important parameter for this type of modelling and is determined with a simple method without using any calorimeter. This paper chooses two types of prismatic cells: lithium titanate (LTO) anode-based cell and nickel manganese cobalt oxide (NMC) with 23 Ah and 43 Ah, respectively. Validation was made by comparing the simulation results with experimental work for which an error of less than 3% was shown.
