Abstract
Systems and methods for achieving controlled load transition between power supplies and battery units are described. A method may include determining that a Power Supply Unit (PSU) coupled to an IHS via a power transmission interface is turned off; allowing a Backup Battery Unit (BBU) coupled to the IHS via the power transmission interface and in parallel with the PSU via a current sharing bus to supply all current consumed by the IHS via the power transmission interface while the PSU is turned off, where the PSU and the BBU are each configured to output a current sharing signal onto the current sharing bus that is indicative of the PSU's or BBU's current being supplied to the IHS via the power transmission interface; reducing a current sharing scaling factor of the BBU; determining that the PSU is turned back on; and increasing the current sharing scaling factor of the BBU.
