Abstract

A single data and power interface, or combination of several such integral data and power interfaces, are used to manage power across one or more batteries and external input power sources. In one embodiment, an interface may be capable of sinking power in order to charge a battery, and then source power from the battery through the same interface. In another embodiment, multiple devices having integrated data and power interfaces are used to manage one or more battery units for emergency power or for mobile operation where the interface may be connected to a power source for charging, but may also be used to source power from the battery to operate another device during mobile operation.

Claims

1. A device comprising:

a first interface comprising data communication and power communication in a first connector;

a battery bank; and

a power management system adapted to;

detect a charge level for said battery bank;

receive power input from said power communication on said first interface;

charge said battery bank using said power input;

determine that a second device connected to said first connector requires output power; and

transferring said output power from said battery to said second device through said first connector.

2. The device of claim 1 wherein said first interface is compliant with at least a subsection of IEEE 802.3.

3. The device of claim 1 wherein said first interface is an Ethernet interface.

4. The device of claim 1 wherein said power management system is further adapted to:

detect a battery type for said battery bank.

5. The device of claim 4 wherein said power management system is further adapted to:

determine a charge profile for said battery bank.

6. The device of claim 1 wherein said power management system is further adapted to:

receive a first command over said data communication; and

configure said first interface to a power source configuration based on said first command.

7. The device of claim 1 wherein said power management system is further adapted to:

receive a second command over said data communication; and

configure said first interface to a power sink configuration based on said second command.

8. The device of claim 1 further comprising:

a processor adapted to;

receive a request through said first connector, said request being a digital communication;

transmitting a response through said first connector.

9. The device of claim 1 further comprising:

a plurality of interface connections, each of said plurality of interface connections comprising data communications and power communications in a single connector.

10. The device of claim 9 wherein said plurality of interface connections being arranged in an arrangement being at least one of a group composed of:

a hub arrangement, a switch arrangement, and a router arrangement.

11. A system comprising:

a first device comprising;

a first interface comprising data communication and power communication in a first connector;

a first battery bank; and

a first power management system adapted to;

detect a charge level for said first battery bank;

receive power input from said power communication on said first interface;

charge said first battery bank using said power input;

determine that a second device connected to said first connector requires output power; and

transferring said output power from said battery to said second device through said first connector;

said second device comprising;

a second interface comprising data communication and power communication in a second connector;

a second battery bank; and

a second power management system adapted to;

detect a charge level for said second battery bank;

receive power input from said power communication on said second interface;

charge said second battery bank using said power input;

determine that said first device connected to said second connector requires output power; and

transferring said output power from said second battery bank to said first device through said second connector.

12. The system of claim 11 wherein at least one of said first interface or said second interface is compliant with at least a subsection of IEEE 802.3.
