Abstract

The present disclosure relates to a method of generating a thermal map for estimating internal temperatures of a battery module. A plurality of cycling operations are performed on a battery module having one or more battery cell. During the cycling operations, a plurality of first temperatures (T1) are measured at first locations; and one or more second temperature (T2) are measured at one or more second locations. The first temperatures (T1) measured at said first locations are cross-plotted with the second temperatures (T2) measured at the one or more second locations. The thermal map can be generated from the analysis of the first and second temperatures (T1, T2). The present disclosure also relates to a battery module having a thermal map for estimating internal temperatures.
