Abstract
A rack power unit is configured to be inserted into a device rack of a data center. The rack power unit includes one or more power supplies and one or more battery packs. The one or more power supplies are each configured to receive power (e.g., AC power) when the apparatus is in the device rack, and convert the received power to a DC power. The one or more power supplies are further configured to output the DC power to a DC power bus of the device rack. The one or more battery packs are each configured to provide, in response to an interruption in the received power, DC power to the DC power bus of the device rack.

9. A data center comprising:
-
a first device rack including a first rack power unit and a first plurality of devices, the first rack power unit including; a first one or more power supplies each configured to receive power, convert the received power to first DC power, and output the first DC power to a DC power bus of the first device rack, and a first one or more battery packs each configured to provide, in response to an interruption in the received power, second DC power to the DC power bus of the first device rack; a second device rack including a second rack power unit and a second plurality of devices, the second device rack power unit including; a second one or more power supplies each configured to receive the power, convert the received power to third DC power, and output the third DC power to a DC power bus of the second device rack, and a second one or more battery packs each configured to provide, in response to an interruption in the received power, fourth DC power to the DC power bus of the second device rack. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A method in a data center, the method comprising:
-
powering, with one or more power supplies in a rack power unit in a device rack, devices in the device rack of the data center with DC power that is converted from received power from an external source into DC power by the one or more power supplies, and wherein the DC power is output by the one or more power supplies to a DC power bus of the device rack; in response to a power interruption, powering the devices in the device rack with DC power from one or more battery packs in the rack power unit, the one or more battery packs outputting DC power to the DC power bus, and powering, after a backup generator is online, the devices in the device rack with received power from the backup generator rather than from the one or more battery packs, the one or more power supplies converting received power from the backup generator to DC power and outputting the DC power on the DC power bus; and providing, from the one or more battery packs in the power unit, DC power to the DC power bus in the event of a peak in power usage by one or more of the devices in the device rack.
