    摘要: 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.

    摘要: A battery performance monitoring system anticipates the sudden fall of battery output. The system measures the battery voltage at a time point when the discharge current of a battery becomes smaller than the reference current value or at a time point when the current to the load which is connected to the battery becomes smaller than the reference current value, and judges the battery to be abnormal if the difference of the measured battery voltage from the approximate formula in regard to the current-voltage relation in the former half of a same discharge event becomes out of the reference range.

In a power system 10, a non-aqueous solution system secondary battery group 1 where 10 to 11 lithium ion secondary battery cells are connected in series and an aqueous solution system secondary battery group 2 where 18 control valve type lead-acid battery cells are connected in series are connected in parallel. The battery capacity of the non-aqueous solution system secondary battery group 1 is smaller than that of the aqueous solution system secondary battery group 2. The non-aqueous solution system secondary battery group 1 and the aqueous solution system secondary battery group 2 are charged at a current value of 7C or less from a motor generator 3, and the ratio of the charged current value of the aqueous solution system secondary battery group 2 to the charged current value of the non-aqueous solution system secondary battery group 1 is 0.05 to 1.00.
