Abstract
The method includes a preparation step of changing a current value or a voltage value of a power storage device; a first measurement step of obtaining a first internal resistance that is an internal resistance when a predetermined first period of time has elapsed from start of change in the current value or the voltage value in the preparation step; a second measurement step of obtaining a second internal resistance that is an internal resistance when a second period of time has elapsed from the start of change in the current value or the voltage value in the preparation step; a calculation step of calculating a resistance value difference by subtracting the first internal resistance from the second internal resistance; and a detection step of detecting generation of gas inside the power storage device based on the resistance value difference.
