Abstract
A power storage system includes: a battery; a voltmeter configured to measure voltage of the battery; an ammeter configured to measure current of the battery; and processing circuitry configured to control charge of the battery to prevent charging power exceeding charging power upper limit from being supplied to the battery. The processing circuitry is further configured to: calculate first charging power, at which the battery reaches voltage upper limit, based on estimated open-circuit voltage, which is an estimated value of open-circuit voltage of the battery, and first estimated internal resistance; calculate second charging power, at which the battery reaches the voltage upper limit, based on the voltage, the current, and second estimated internal resistance; and set the charging power upper limit, based on the first charging power and the second charging power.
