Title:
DETERIORATION DETECTOR FOR NON-AQUEOUS ELECTROLYTE POWER STORAGE ELEMENT, POWER STORAGE DEVICE, DETERIORATION DETECTION SYSTEM FOR NON-AQUEOUS ELECTROLYTE POWER STORAGE ELEMENT, AND DETERIORATION DETECTION METHOD FOR NON-AQUEOUS ELECTROLYTE POWER STORAGE ELEMENT
Document Type and Number:
WIPO Patent Application WO/2016/158354
Kind Code:
A1
Abstract:
The invention according to the present embodiment detects the deterioration of a non-aqueous electrolyte power storage element on the basis of: a first increase rate which is the increase rate of a direct current resistance value obtained by measuring the non-aqueous electrolyte power storage element over a first time period; and a second increase rate which is the increase rate of a direct current resistance value obtained by measuring the non-aqueous electrolyte power storage element over a second time period that is longer than the first time period.
