Abstract
Systems for controlling cycling operations for backup battery units in a datacenter include groups of backup battery units and power supply units that can supply power to datacenter components from either a primary power supply or, the backup battery units. Each group of multiple battery units has sufficient capacity to provide backup power to a respective electronic device even when one battery unit is offline. In operation, a controller receives requests to perform cycling operations, e.g. maintenance, on the backup batteries. Upon each request, the system retrieves status information corresponding to each backup battery unit and determines whether the remainder of the backup battery units can supply sufficient power to meet or exceed power demand, and either allow or prevent each backup battery unit from performing the cycling operation in response to determining whether the remainder of the backup battery units can or cannot supply sufficient power.
