Abstract
A method for determining a temperature estimating model for estimating a temperature in a battery module includes: estimating temperatures using a preliminary verification profile with models based on respective parameter sets; calculating first errors corresponding to differences between measured and estimated temperatures; comparing whether respective first errors for the respective parameter sets are less than a first threshold value; for parameter sets having a first error that is less than the first threshold value, calculating a maximum error; extracting a second parameter set by calculating a product of the maximum error and a first value plus a product of the first error and a second value; estimating temperatures according to reverification profile; calculating a second error corresponding to a difference between measured temperatures of the reverification profile and estimated temperatures; and finalizing the model when the second error is less than a third threshold value.
