Original Abstract Submitted
through an experiment or the like, a degradation contribution relation representing a relation between each of n battery state-related variables and a decrease in full charge capacity is obtained. historical data on the variables is collected from l battery electric vehicles, and l simple estimated values of full charge capacity after degradation are obtained by using the degradation contribution relations. a correlation coefficient between the l historical data sets on each variable and the l simple estimated values is calculated, and m variables having the correlation coefficient exceeding a predetermined threshold are selected. an equation is formulated where the selected variables are explanatory variables and a high-accuracy estimated value of full charge capacity after degradation is an objective variable. the coefficients are determined by substituting k historical data sets into the variables of the equation and substituting k simple estimated values into a left side of the equation.
