CHARGE-DISCHARGE CONTROLLER, SYSTEM AND METHOD

摘要

A charge-discharge system includes a consolidation ECU and a plurality of storage batteries having equal rated capacities for charging electric power from a power grid and for discharging electric power stored therein. The consolidation ECU is configured to perform a charge operation or a discharge operation exclusively on only one of the plurality of storage batteries at a time, according to a priority order of each of the plurality of storage batteries, without performing a charge operation or a discharge operation on more than one of the plurality of storage batteries simultaneously. In such manner, in a system having a plurality of storage batteries having equal rated capacities, drastic fluctuation of charge/discharge electric power is prevented.

主权项

1. A charge-discharge controller comprising:
a control section controlling a charge operation of a plurality of storage batteries having equal rated capacities which charges electric power from a power grid to the plurality of storage batteries, and a discharge operation of the plurality of storage batteries which discharges electric power stored in the plurality of storage batteries, wherein the control section performs the charge operation or the discharge operation on only one of the plurality of storage batteries at a time, according to a priority order of the plurality of storage batteries, without performing a charge operation or a discharge operation on more than one of the plurality of storage batteries simultaneously.
