Abstract

Backup power supply systems and methods are disclosed. An exemplary method includes providing at least one battery module having a first register with at least one battery parameter. The method also includes coupling an intelligent interface converter (IIC) between the at least one battery module and an electrical load, the IIC having a second register with at least one battery parameter. The method also includes communicating the at least one battery parameter to a user for reporting and management operations.

Claims

1. A backup power supply system comprising:

a battery module having a first register with at least one battery parameter;

an intelligent interface converter (IIC) communicatively coupled to the battery module, the IIC having a second register with at least one battery parameter; and

wherein the IIC connects via an interconnect and management (IM) to an electrical load, the IM communicating report and management parameters based on the at least one battery parameter in the first and second registers, wherein the registers provide customized power configuration for when the backup power supply system is providing power.

2. The backup power supply system of claim 1, wherein customized power configuration provides power from the battery module only for high priority electronics, and wherein low priority electronics power off.

3. The backup power supply system of claim 1, wherein customized power configuration provides power from the battery module only for a predetermined output level.

4. The backup power supply system of claim 1, wherein customized power configuration provides power from the battery module to lengthen ride-through times.

5. The backup power supply system of claim 1, further comprising a common interface between the IIC and the battery module for interchanging battery modules having different cell chemistry and number of cells with the same IIC.

6. The backup power supply system of claim 1, wherein the IIC connects to a DC rail through the IM so that the battery module is off-grid, the DC rail includes a low voltage rail or a high voltage rail.

7. The backup power supply system of claim 1, wherein the battery module is sized to fit in a 1 U rack chassis and electrically connected in parallel with other battery modules in a rack system.

8. The backup power supply system of claim 1, wherein at least two interrupts are indicated for the IIC, wherein one of the at least two interrupts is an early stop discharge warning, and wherein one of the at least two interrupts is a final stop discharge warning.

9. The backup power supply system of claim 1, wherein the IIC receives battery parameters from the first register to interface with the battery module.

10. The backup power supply system of claim 9, wherein interfacing with the battery module includes at least one of:

charging, battery health monitoring, temperature reporting, controlled discharge, battery compatibility, sizing.

11. The backup power supply system of claim 1, wherein the IM receives battery parameters from the first and second registers to control one or more function for the electrical load.

12. The backup power supply system of claim 11, wherein the one or more function for the electrical load is at least one of:

fan control, controlled discharge, budgeting charging power, budgeting discharging power, monitoring and reporting, and system interfacing.

13. A backup power supply comprising:

at least one battery module having a first register with at least one battery parameter;

an intelligent interface converter (IIC) communicatively coupled between the at least one battery module and an electrical load, the IIC having a second register with at least one battery parameter; and

wherein the at least one battery parameter is communicating to a user for reporting and management operations, wherein the registers provide customized power configuration for when the backup power supply system is providing power.

14. The backup power supply system of claim 13, wherein the same IIC is configured to couple with at least one more battery module for scalability.

15. The backup power supply system of claim 13, further comprising a common interface between the IIC and the battery module for interchanging battery modules having different cell chemistry and number of cells with the same IIC.

16. The backup power supply system of claim 13, wherein the IIC receives battery parameters from the first register to interface with the battery module.

17. The backup power supply system of claim 13, further comprising an interconnect and management (IM) configured to control one or more function for the electrical load based on battery parameters in the first and second registers.

18. A method of controlling a backup power supply comprising:

providing at least one battery module having a first register with at least one battery parameter;

coupling an intelligent interface converter (IIC) between the at least one battery module and an electrical load, the IIC having a second register with at least one battery parameter; and

communicating the at least one battery parameter to a user for reporting and management operations, wherein the registers provide customized power configuration for when the backup power supply system is providing power.

19. The method of claim 18, further comprising interfacing the IIC with the battery module based on battery parameters in the first register, and controlling one or more functions for the electrical load based on battery parameters in the first and second registers.

20. The method of claim 18, further comprising continuing to provide power to electronic devices in other domains even if one domain is lost due to failure of one of a plurality of battery modules.
