Abstract
This charge and discharge system comprises a battery connected to a bus to which multiple power a generator and an electric power transmission system are connected, a charger configured to supply power from the bus to the battery, a discharger separate from the charger and configured to output electric power from the battery to the bus, and a controller configured to separately control the charger and the discharger.
Claims21
An electrical charge and discharge system, comprising:
- a battery connected to a bus to which multiple power a generator and an electric power transmission system are connected;
- a charger configured to supply power from the bus to the battery;
- a discharger separate from the charger and configured to output electric power from the battery to the bus;
- and
- a controller configured to separately control the charger and the discharger.
A method of managing a battery and a power generator, comprising:
- detecting power outputted from the power generator;
- determining target output value to be supplied to an electric power transmission system;
- and
- controlling the battery so that electric power corresponding to a difference between the detected power and the target output value is charged to the battery when the detected power is greater than the target output value and that electric power corresponding to a difference between the detected power and the target output value is discharged from the battery to the electric power transmission system when the detected power is smaller than the target output value.
A computer-readable recording medium which records a control program for causing one or more computers to perform the steps comprising:
- receiving a result of detection of power outputted from a power generator;
- calculating target output value to be supplied to an electric power transmission system;
- and
- controlling a battery so that electric power corresponding to a difference between the detected power and the target output value is charged to the battery when the detected power is greater than the target output value and that electric power corresponding to a difference between the detected power and the target output value is discharged from the battery to the electric power transmission system when the detected power is smaller than the target output value.
A device managing a battery, comprising:
- a charger configured to supply power to the battery;
- a discharger separate from the charger and configured to output electric power to an electric power transmission system;
- and
- a controller configured to control the charge and the discharger so that electric power corresponding to a difference between power generated by a generator and target output value to be supplied to the electric power transmission system is charged to the battery when the generated power is greater than the target output value and that electric power corresponding to a difference between the generated power and the target output value is discharged from the battery to the electric power transmission system when the generated power is smaller than the target output value.
