Abstract

A system for utilizing an array of electrical energy storage devices utilizes a smart manager that categorizes electrical energy storage devices in the array based on electrical energy storage device age and/or internal resistance level and causes those electrical energy storage devices with similar ages and/or resistance levels to be concurrently depleted. This is followed by concurrently depleting the electrical energy storage devices in a different category. The system also disconnects faulty electrical energy storage devices in the array and helps alleviate the need to carefully consider and reconfigure the location of individual electrical energy storage devices in the array. The system facilitates forecasting actual capacity and thus helps to guarantee available capacity and to actively maintain capacity via maintenance crews that need simply remove and replace cells as advised by the smart manager. The system 100 facilitates permitting a quality of service (QoS) to be provided to mission critical entities (banks, hospitals, etc.).

Claims

1. A system for utilizing an array of batteries, comprising:

at least one controller; and

at least one communications module embedded in each of the batteries, wherein the at least one controller is configured to;

receive information from the batteries, wherein the received information includes age information of the batteries;

determine, based on the age information, a first set of batteries having a first age range;

determine, based on the age information, a second set of batteries having a second age range newer than the first age range;

connect the first set of batteries in parallel so as to allow power to be drawn from the first set of batteries;

connect the second set of batteries in parallel the so as to allow power to be drawn from the second set of batteries; and

selectively connect the batteries in each set to power a load so that batteries in the same age range are utilized at the same time.

2. The system of claim 1 wherein the age information received from each battery includes one or more of:

includes an age of each battery;

a remaining life expectancy of each battery and a manufacturing batch of each battery.

3. The system of claim 1 wherein the at least one controller is configured to:

determine from the received information that a battery is faulty;

in response to the determination that the battery is faulty, prevent power from being drawn from the faulty battery.

4. The system of claim 3 wherein the at least one controller is further configured to:

disconnect the faulty battery from the set of batteries in the same age range.

5. The system of claim 3 wherein the at least one controller is further configured to:

send a signal to initiate a replacement of the faulty battery in the set of batteries in the same age range.

6. The system of claim 1 wherein the at least one controller is configured to:

determine a depletion plan for the first set of batteries and the second set of batteries.

7. The system of claim 6 wherein the at least one controller is configured to:

cause power to be drawn from the first or second set of batteries according to the determined depletion plan.

8. The system of claim 1 wherein the at least one controller is configured to:

cause each battery in the first set of batteries to be electrically connected to a first electrical circuit;

cause each battery in the first set of batteries to be electrically disconnected from the first electrical circuit of the array to prevent further power from being able to be drawn based on detection of a minimum present charge level being reached associated with the first set of batteries;

cause each battery in the second set of batteries to be electrically connected to a second electrical circuit; and

cause each battery in the second set of batteries to be electrically disconnected from the second electrical circuit to prevent further power from being able to be drawn based on detection of the minimum present charge level being reached associated with the second set of batteries.

9. The system of claim 7 wherein the at least one controller is further configured to forecast actual electrical energy capacity of the batteries in each set based on the age information.

10. The system of claim 7 wherein the array of batteries is operably connected to the at least one controller.

11. The system of claim 10 wherein the array of batteries is operably connected to the at least one controller via a communications link and via an electrical circuit.

12. A method performed by a system for utilizing an array of batteries, the method comprising:

receiving, information from the batteries, wherein the received information includes age information of the batteries;

determining, by a controller of the system based on the age information, a first set of batteries having a first age range;

determining, by the controller based on the age information, a second set of batteries having a second age range newer than the first age range;

connecting the first set of batteries in parallel so as to allow power to be drawn from the first set of batteries;

connecting the second set of batteries in parallel so as to allow power to be drawn from the second set of batteries; and
