A method for controlling charging and discharging of a rechargeable battery with a controller includes acquiring a measured current, a measured voltage, and a measured temperature; estimating an estimated voltage based on the measured current and the measured temperature; collecting samples each indicating a difference between the measured voltage and the estimated voltage; classifying the samples into an upper limit side determination sample and a lower limit side determination sample with reference to a reference value; calculating an upper limit error based on at least a predetermined quantity of the upper limit side determination sample, and calculating a lower limit error based on at least a predetermined quantity of the lower limit side determination sample; and resetting an upper limit of a usable SOC range in accordance with the upper limit error, and resetting a lower limit of the usable SOC range in accordance with the lower limit error.
