CHARGING AND DISCHARGING CONTROL DEVICE CHARGING CONTROL METHOD DISCHARGING CONTROL METHOD AND PROGRAM

摘要

When power required by a load (120) is greater than or equal to a receiving peak cut power a charging and discharging control device (150) allows a secondary battery (140) to discharge power greater than or equal to the difference between the required power and the receiving peak cut power. When the required power is less than the receiving peak cut power the charging and discharging control device (150) allows the secondary battery (140) to discharge power less than or equal to a discharge optimization power value. Alternatively when the regenerative power of the load (120) is greater than or equal to a transmitting peak cut power the charging and discharging control device (150) allows the secondary battery (140) to be charged by power greater than or equal to the difference between the regenerative power and the transmitting peak cut power. When the regenerative power is less than the transmitting peak cut power the charging and discharging control device (150) allows the secondary battery (140) to be charged by power less than or equal to a charging optimization power value.
