PROBLEM TO BE SOLVED: To learn a gain error of a current sensor.SOLUTION: A power storage system includes: a power storage device (10) that is charged by receiving direct current power from a charger (28) installed outside; a current sensor (22) for detecting a current value of the power storage device; and a controller (30) for obtaining a current value when the charger is supplying direct current power to the power storage device by communication with the charger. The controller calculates a gain error of the current sensor on the basis of the current value detected by the current sensor and the current value obtained from the charger, and corrects the current value detected by the current sensor using the gain error. The power storage system can learn the gain error of the current sensor using the current value with high detection accuracy obtained from the charger. |
