Modelling thermal behaviour of battery packs in pure electric vehicles (BEVs) is one of the most demanding tasks in powertrain design activities. The complexity is given by the need of considering several aspects like internal geometry, cooling circuit, etc. for which the standard approach based on equivalent circuit model seems not to be adequate. The aim of this paper is instead to demonstrate how it is possible to maintain the equivalent circuit model approach, by making minimal changes and by using data from vehicle CAN network. Then, the model can be used to correctly achieve battery pack temperature under different realistic use conditions.

Abstract

Modelling thermal behaviour of battery packs in pure electric vehicles (BEVs) is one of the most demanding tasks in powertrain design activities. The complexity is given by the need of considering several aspects like internal geometry, cooling circuit, etc. for which the standard approach based on equivalent circuit model seems not to be adequate. The aim of this paper is instead to demonstrate how it is possible to maintain the equivalent circuit model approach, by making minimal changes and by using data from vehicle CAN network. Then, the model can be used to correctly achieve battery pack temperature under different realistic use conditions.
