    Abstract: A battery status detecting method for detecting a battery status of a secondary battery is disclosed. The method includes: an open circuit voltage correcting step of obtaining a temperature-corrected value of the open circuit voltage of the secondary battery according to the temperature of the secondary battery, based on first open circuit voltage characteristics indicating the relationship between the open circuit voltage and the temperature of the secondary battery; and a charge rate correcting step of obtaining a temperature-corrected value of the charge rate of the secondary battery according to the temperature-corrected value of the open circuit voltage obtained in the open circuit voltage correcting step, based on second open circuit voltage characteristics indicating the relationship between the open circuit voltage and the charge rate of the secondary battery.
