Non-aqueous electrolyte storage element deterioration detector, power storage device, non-aqueous electrolyte storage element deterioration detection system, and non-aqueous electrolyte storage element deterioration detection method

摘要

According to an embodiment of the present invention, deterioration of a non-aqueous electrolyte power storage element is detected based on a first increase rate and a second increase rate, the first increase rate being an increase rate of a direct current resistance value obtained by measuring the non-aqueous electrolyte power storage element over a first time period, the second increase rate being an 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.
