| description | A battery management apparatus 102 is an apparatus which manages a chargeable and dischargeable battery, and includes: a battery state calculation unit 501 which calculates a state of charge SOC representing the state of charge of the battery, and a charge capacity fade SOHQ representing a deterioration degree; a mid voltage calculation unit 502 which calculates a mid voltage that is present between the discharge voltage in a current state of charge of the battery, and a voltage value representing the discharge voltage in a minimum state of charge of the battery; a remaining capacity calculation unit 503 which calculates a remaining capacity of the battery, based on the state of charge SOC and the charge capacity fade SOHQ; and an available energy calculation unit 504 which calculates available energy of the battery, based on the mid voltage and the remaining capacity. |
