A module 30 is provided with 8 pieces of single batteries 20 each using a laminate film as its battery container. The 8 pieces of single batteries are disposed in a layer-stacked state. A conducting plate 17 is placed in a manner to face one single battery 20a disposed at one end of the 8 pieces of the single batteries 20. A pushing member 14 is formed between the single battery 20a and conducting plate 17. A conducting plate 18 is disposed on a side of the conducting plate 17 opposite to the pushing member 14.

摘要： The present invention relates to a status detector for a power supply, a power supply, and an initial characteristic extracting device for use with the power supply, each of which can detect the status of an electricity accumulating unit (200) with high accuracy by sequentially modifying characteristic information necessary for the status detection of the electricity accumulating unit (200). A measuring unit (300) obtains measured values of at least current, voltage and temperature of the electricity accumulating unit (200). A processing unit (110) executes status detection of the electricity accumulating unit (200) by using the measured values and the characteristic information of the electricity accumulating unit (200) which is stored in a memory unit (130). A discrepancy detecting unit (120) detects the presence of a discrepancy away from a theoretical value when a result of the status detection obtained by the processing unit (110) is changed over a predetermined threshold or reversed with respect to the measured values obtained by the measuring unit (300). A modifying unit (140) modifies the characteristic information stored in the memory unit (130) depending on the discrepancy detected by the discrepancy detecting unit (120).
