Apparatus and method for detecting the state of a battery

摘要

A state detecting system comprises a storage means (103) for storing a characteristic data (SOCo) on a power storage means (101) arithmetically obtained on the basis of the measured information obtained by measuring a measuring object with respect to said power storage means by measuring means (102), calculation information relating to said arithmetic operation of said data, and set information preliminarily set as said characteristic data and said calculation information, an arithmetic means (104) for calculating state information (SOC, SOH) indicative of state of said power storage means on the basis of said measured information and set information and calculating correction information (K) for performing correction by comparing a calculation result calculated and said set information, said storage means (104) storing two or more mutually different calculation procedures (701, 702) and said arithmetic means deriving said correction information on the basis of a difference of calculation results by saidmutually different calculation procedure.
