要約(英語): The increase in temperature of a traction battery installed on a battery-powered electric multiple-unit train (EMU) can be easily estimated using the equivalent thermal circuit model. However, the accuracy of the estimated temperature depends on the parameters (thermal capacities and resistances) used in the model. To overcome this problem, we developed a parameter fitting method to automatically identify the optimal parameters for the model. The method requires only the measured temperature and current curves of the battery system, which can be obtained by performing a test run. The accuracy of the estimated temperatures and the effect of the cooling fans were quantitatively evaluated by applying the proposed method to the test-run results of the battery-powered EMU.
