45　Creation of LiB deterioration model based on various literature data and its difference from theoretical de terioration model formula when assuming residential load

Abstract

To reproduce the LIB battery performance, data from various literatures was collected and fitted to the main deterioration factor characteristic graphs. As a result, it was confirmed that the deterioration factor FEC has a power function, the temperature has a composite function of the Arrhenius and inverse Arrhenius equations, and the C rate has a cubic function. By incorporating these functions, a deterioration model with a maximum RMSPE of 4.97 % was created. In addition, the model described in the book and the created model were evaluated in terms of deterioration transition and in a 15-year charge/discharge simulation assuming an ordinary home.
