Abstract

This invention is a battery case evaluation system 100 for evaluating thermal characteristics of a battery case (BC) constituting a battery pack or a component of the battery case (BC). The battery case (BC) comprises a simulated battery 10 that is installed within the battery case (BC) and that is to simulate thermal behavior of the actual battery which is a component of the battery pack, a power supply device 20 that supplies power to the simulated battery 10, and a control device 30 that controls the power supply device 20. The control device 30 comprises a parameter receiving unit 31 that receives an input profile indicating time-dependent change of a current, a voltage, or power supplied to the actual battery as one of evaluation parameters, a resistance value calculation unit 331 that calculates a resistance value of the actual battery which changes over time based on simulated battery temperature and the input profile, and a power supply control unit 33 that controls the power supply device 20 using the resistance value calculated by the resistance value calculation unit 331.
