Status Detector for Power Supply, Power Supply, and Initial Characteristic Extracting Device for Use with Power Supply
First Claim
1. A status detector for a power supply, comprising:
- measuring means capable of obtaining measured values of at least current, voltage and temperature of electricity accumulating means;
memory means for storing characteristic information of said electricity accumulating means;
processing means for executing status detection of said electricity accumulating means by using the measured values and the characteristic information of said electricity accumulating means which is stored in said memory means;
discrepancy detecting means for detecting the presence of a discrepancy away from a theoretical value when a result of the status detection obtained by said processing means is changed over a predetermined threshold or reversed with respect to the measured values obtained by said measuring means; and
modifying means for modifying the characteristic information stored in said memory means depending on the discrepancy detected by said discrepancy detecting means.

Abstract
In a status detector for a power supply, a power supply, and an initial characteristic extracting device for use with the power supply, a measuring unit obtains measured values of at least current, voltage and temperature of the electricity accumulating unit. A processing unit executes status detection of the electricity accumulating unit by using the measured values and the characteristic information of the electricity accumulating unit which is stored in a memory unit. A discrepancy detecting unit detects the presence of a discrepancy away from a theoretical value when a result of the status detection is changed over a predetermined threshold or reversed with respect to the measured values. A modifying unit modifies the characteristic information depending on the detected discrepancy.
