Title: BATTERY STATE ESTIMATING DEVICE AND POWER SUPPLY DEVICE
Abstract:
An internal resistance estimating unit (811) estimates an internal resistance (R) of a secondary battery. A state of health_resistance (SOH_R) calculating unit (812) calculates a SOH_R on the basis of the secondary battery internal resistance (R) thus estimated. A storage unit (70) stores a state of health_resistance-state of health_capacity (SOH_R-SOH_C) table. A SOH_C calculating unit (813) refers to the SOH_R-SOH_C table, and calculates a SOH_C on the basis of the SOH_R thus calculated. An FCC estimating unit (814) estimates a full charge capacity (FCC) on the basis of the SOH_C thus calculated.
