PROBLEM TO BE SOLVED: To provide capacity evaluation method and evaluation device which allows for shortening of the temperature holding time of a secondary battery, and acquisition of highly reproducible capacity data.SOLUTION: A secondary battery capacity evaluation method for evaluating the capacity of a secondary battery by changing the environmental temperature thereof maintains the environmental temperature at a preset temperature, and under that state, begins measurement of the capacity based on the change of the AC impedance of the secondary battery. |
