Abstract
A state detecting system which can detect state of power storage at high precision even with lesser characteristic data to be used for calculation, and a device employing the same. The state detecting system has a memory for storing a characteristic data, calculation information, and set information, an arithmetic unit for calculating state information indicative of state of said power storage and calculating correction information for performing correction, a first correcting unit for correcting input of said arithmetic means, and a second correcting unit for correcting information stored or set in the storage.
