Examples of the disclosure include an uninterruptible power supply (UPS) system (100) comprising at least one energy-storage-device interface (110) configured to be coupled to a plurality of batteries (204a-204b), battery-identification circuitry (208a-208c) configured to be coupled to the plurality of batteries (204a-204b), the battery-identification circuitry (208a-208c) being further configured to receive a plurality of output signals from the plurality of batteries (204a-204b), determine energy-storage-device information indicative of at least one battery type of the plurality of batteries based on the plurality of output signals (210a-210-c) received from the plurality of batteries (204a-204b), and output the energy-storage-device information (212a-212-c), and processing circuitry (206) configured to receive the energy-storage-device information, and select a battery profile indicative of one or more battery parameters based on the energy-storage-device information.

A rack equipment removal tool includes a handle and a housing having a rotation shaft. The handle is coupled to the rotation shaft and configured to rotate with respect to the housing about the rotation shaft. The rack equipment removal tool further includes a hook having a first end coupled to the handle and a second end having a fastener configured to be coupled to a power module. The rack equipment removal tool further includes a frame mounting fastener coupled to the housing. The frame mounting fastener is configured to be coupled to a frame of an equipment rack supporting the power module. Rotation of the handle causes the movement of the hook to partially remove the power module from the equipment rack.

A system for managing addressing is provided, the system including a first subordinate device coupled to a communication bus, a first address line, and a second address line, the first subordinate device including a first switch coupled between the first address line and the second address line and configured to selectively connect the first address line to the second address line, a first alarm input configured to receive an alarm signal, and a second switch configured to establish an alarm voltage on the first address line.

A method for discovering devices on a system is presented, including receiving, at a server, instructions to operate an application; responsive to receiving the instructions to operate the application, discovering, with the application, one or more devices based on one or more criteria, the application discovering the one or more devices by accessing one or more gateways in communication with the server and, through the one or more gateways, identifying the one or more devices meeting the one or more criteria; and providing data corresponding to the one or more devices.

The present invention relates to a battery pack, comprising: an enclosure; a first battery supported by the enclosure, the first battery including a first terminal and a second terminal; a second battery supported by the enclosure and proximate to the first battery, the second battery including a third terminal and a fourth terminal; and a printed circuit board including a first connector coupled to the first terminal, a second connector coupled to the second terminal, a third connector coupled to the third terminal, and a fourth connector coupled to the fourth terminal.

A battery cartridge assembly is configured to be positioned behind a UPS having a back side facing a first direction. The battery cartridge assembly includes a housing having a front side and a back side. The front side of the housing is configured to face the back side of the UPS when positioning the housing of the battery cartridge assembly behind the UPS. The battery cartridge assembly further includes a first connector provided on the back side of the housing. The first connector is configured to accept a UPS cable. The first connector faces the first direction. The battery cartridge assembly further includes a cutout in the housing. The cutout is configured to route a UPS cable between the UPS and the first connector.

A power system (100) for a data center is presented, the power system (100) including a first rack (114); a first power converter (102) coupled to a first rack first input, the first power converter being configured to adjust a first output voltage of the first power converter (102) based on a first portion of the first DC power; a second power converter (106) coupled to a first rack second input, the second power converter being configured to provide second DC power to the first rack (114) and to the second rack, the second power converter (106) further being configured to adjust a second output voltage of the second power converter based on a first portion of the second DC power and a second portion of the second DC power; a first asymmetric-conductance device (120) coupled between the first power converter (102) and first rack (114); and a second asymmetric-conductance device (122) coupled between the second power converter (106) and first rack (114).

A charging apparatus is provided according to some embodiments. The charging apparatus includes (1) charging circuitry configured to connect to a plurality of battery packs in parallel and (2) processing circuitry configured to control the charging circuitry by: (a) obtaining a voltage reading from each of the plurality of battery packs; (b) initially setting a charging voltage of a charger to a lowest voltage reading obtained from any of the plurality of battery packs; (c) while applying the charging voltage to the plurality of battery packs, obtaining a current reading from each of the plurality of battery packs that is charging; and (d) in response to the obtained current reading from a battery pack being below a minimum threshold current, increasing the charging voltage by a voltage step value. A similar method and computer program product are also provided.

A computer program product is provided according to some embodiments. The computer program product includes a non-transitory computer-readable storage medium storing a set of instructions, which, when executed by a computing device, causes the computing device to: (a) determine a discharge rate for a battery at a remote location based on a profile of the battery and a temperature value; (b) receive, at an initial time, a notification of the battery ceasing to be in communication with the computing system; (c) in response to receiving the notification, estimate an amount of time remaining until the battery self-discharges to a lower threshold state of charge (SoC); and (d) in response to elapsed time since the initial time reaching the estimated amount of time, output a signal from the computing system indicating a battery-discharge condition. A corresponding method, apparatus, and system are also provided.
