Abstract
Lithium ion batteries are the most viable option for electric vehicles but they still have significant limitations. Safety of these batteries is one of the concerns that need to be addressed when they are used in mainstream vehicles, because of heating issues that may lead to thermal runaway. This work aims at supplementing the existing electrochemical heat distribution model of a spirally wound lithium ion battery with an electrical network that can model the heat losses due to electric resistances of the current collectors. The developed electrical network model is used to calculate the current and state-of-charge distribution throughout the spiral jelly roll, which can be used to determine electric heat losses. The results obtained from this model can then be used to optimize the shape and dimensions of the current collectors as well as the materials used in them.
