1. A state detecting system comprising:

  • a memory means for storinga characteristic data of power storage means, obtained by calculation from an measured information obtained by measuring a measuring object of power storage means by way of measurement means;

    a calculation information required for said calculation for said characteristic data; and

    a set information to be defined for a characteristic or phenomenon specific to said power storage means as true set value or true logic, said set information set in advance;

    an arithmetic means forinputting an information stored in said memory means and said measured information as an input information;

    calculating a state information indicating a state of said power storage means based on said input information and said calculation information; and

    calculating a correction information for correcting an information stored in said memory means or said input information in case that it is required to correct an information stored in said memory means or said input information by comparing a result obtained by said calculation and said set information; and

    a correcting means for correcting said input information or an information stored in said memory means based on said correction information, whereinwhen a current value in said power storage means is smaller than or equal to a predetermined value, one of a measured value by said measuring means, said result of calculation and a calculation procedure of said arithmetic means is taken as said set information to derive said correction information.
