An uninterruptible power system includes a plurality of uninterruptible power units connected in parallel to input power. One uninterruptible power unit includes a rechargeable battery, a charging circuit that supplies a charging current to the rechargeable battery, and an output circuit that outputs power supplied from the rechargeable battery as output power. The uninterruptible power system includes a path switching unit in which switching of a path for power received among the charging circuit, the rechargeable battery and the output circuit in the plurality of uninterruptible power units is performed, and a control unit that controls the path switching unit so that switching of the path is performed according to states of the uninterruptible power units.
An uninterruptible power system comprising:
A method of controlling a power supply in an uninterruptible power system, the method comprising:
A computer-readable recording medium having a program stored therein for causing a computer to execute a control step of controlling, according to states of a plurality of uninterruptible power units each including a rechargeable battery, a charging circuit configured to charge the rechargeable battery using input power, and an output circuit configured to output power stored in the rechargeable battery in place of the input power when supply of the input power stops, a path switching unit so that switching of a path for power received among the charging circuit, the rechargeable battery and the output circuit in the plurality of uninterruptible power units is performed, the uninterruptible power units being connected in parallel to the input power.
