ABSTRACT:
Motor generator (MG) is controlled via motor controller by MG control processor of CPU, so that voltage and current of battery is detected while changing frequency of state detection current flowing in the secondary battery. According to the detection results, impedance is calculated in the impedance calculation unit. Remaining mount is calculated from the impedance obtained and the battery characteristics stored in memory. Furthermore, remaining amount change correction unit adds integration current between impedance measurements to the remaining amount for correcting the remaining amount. Weighting coefficient is determined from the standard deviation based on the corrected value and the remaining amount and weighted mean is calculated in weighted mean unit. Next, the result of the remaining amount calculation is used to perform service life calculation and service life correction calculation, and weighted mean is calculated in the same way as the remaining amount.
