Abstract: An electrical storage system includes an electrical storage device, a voltage sensor, a current sensor and a controller. The electrical storage device is configured to be charged with electric power from an external power supply. The controller is configured to detect a first voltage value with the use of the voltage sensor in a state where external charging is temporarily stopped, and calculate a first state of charge corresponding to the first voltage value, when an elapsed time from when external charging at a predetermined electric power is started is longer than or equal to a predetermined time. The predetermined time is a time required until a convergence of a voltage variation resulting from polarization during external charging. The controller is configured to detect a second voltage value with the use of the voltage sensor, when the charging is resumed at the predetermined electric power after the charging is temporarily stopped and then the charging is stopped again, and calculate a second state of charge corresponding to the second voltage value. The controller is configured to calculate a full charge capacity from an accumulated value of the current value in a period from when the charging is resumed to when the charging is stopped and a variation between the first state of charge and the second state of charge, when a difference between a rate of change corresponding to the first voltage value and a rate of change corresponding to the second voltage value is smaller than or equal to an allowable value. The rate of change is identified from the correlation, and indicates the ratio of a variation in open circuit voltage to a variation in state of charge.
