Abstract

A method for prioritized charging of battery backup units (BBUs) is provided. The method may include identifying critical system racks associated with computing data centers based on characteristics associated with the system racks on the computing data centers. The method may also include identifying critical system enclosures associated with the identified critical system racks based on system architectures associated with the computing data centers. The method may further include prioritizing the identified critical system enclosures based on parameters associated with the identified critical system enclosures. The method may also include identifying and ranking a plurality of critical BBUs associated with the identified and prioritized critical system enclosures based on prioritized charging rules associated with the plurality of critical BBUs. The method may further include charging the identified and ranked plurality of critical BBUs in an order based on the prioritized charging rules.

Claims

1. A method for prioritized charging of battery backup units (BBUs), the method comprising:

identifying a plurality of critical system racks associated with at least one computing data center based on a plurality of characteristics associated with a plurality of system racks on the at least one computing data center, wherein the at least one computing data center comprises a hierarchical computing system comprising the plurality of system racks, wherein the plurality of system racks includes a plurality of system enclosures, and wherein the plurality of system enclosures includes a plurality of BBUs;

identifying a plurality of critical system enclosures associated with the identified plurality of critical system racks based on a system architecture associated with the at least one computing data center;

prioritizing the identified plurality of critical system enclosures based on a plurality of parameters associated with the identified plurality of critical system enclosures, wherein prioritizing comprises ranking the plurality of critical system enclosures based on the plurality of parameters;

identifying and ranking a plurality of critical BBUs associated with the identified and prioritized plurality of critical system enclosures based on prioritized charging rules associated with the plurality of critical BBUs, wherein identifying the plurality of critical BBUs comprises identifying the plurality of critical BBUs based on a state of charge associated with a plurality of BBUs on the plurality of critical system enclosures and based on a battery age associated with the plurality of BBUs;

wherein the prioritized charging rules comprises a first prioritized charging rule that includes prioritized charging of a first set of critical BBUs associated with the plurality of critical BBUs over a second set of critical BBUs associated with the plurality of critical BBUs based on a state of charge of the plurality of critical BBUs, wherein the first set of critical BBUs includes a higher state of charge than the second set of critical BBUs;

wherein the prioritized charging rules comprises a second prioritized charging rule that includes, in response to the plurality of critical BBUs associated with the first set of critical BBUs and the second set of critical BBUs having a same state of charge, prioritized charging of the first set of critical BBUs and the second set of critical BBUs based on a battery age associated with the plurality of critical BBUs; and

charging the identified and ranked plurality of critical BBUs in an order based on the prioritized charging rules, comprising charging first the first set of critical BBUs then charging the second set of critical BBUs based on the prioritized charging rules, wherein the first set of critical BBUs and the second set of critical BBUs includes the identified and ranked plurality of critical BBUs.
