Abstract

A matrix system for a battery, which includes a first parameter of power usage and a first requirement, which designates a portion of the first parameter is disclosed. The system further includes a second parameter of temperature and a second requirement, which designates a portion of the second parameter. Also, a third parameter of state of charge and a third requirement, which designates a portion of the third parameter, is described. The portions of the first, second and third parameters intersect to form a volume.

Claims

1. A method for designing a battery application system having a power usage range, a temperature range, and a state of charge range, said method comprising the steps of:

constructing a matrix containing the power usage range, temperature range, and state of charge range;

designating a volume within said matrix, said volume defining battery application parameters; and

reconciling said volume with an application;

thereby designing the battery application model.

2. The method as recited in claim 1, wherein said step of designating includes the step of designating the power usage range necessary for operation of said application.

3. The method as recited in claim 1, wherein said step of designating includes the step of designating the temperature range necessary for operation of said application.

4. The method as recited in claim 1, wherein said step of designating includes the step of designating the state of charge range necessary for operation of said application.

5. A battery application system comprising:

a matrix having a first parameter, a second parameter, and a third parameter;

a first requirement designating a portion of said first parameter;

a second requirement designating a portion of said second parameter;

a third requirement designating a portion of said third parameter;

such that a volume is formed within said matrix at an intersection of said portions of said first, second and third parameters;

a battery defined by said volume within said matrix;

a first application for said battery; and

a controller, wherein said controller determines whether said first application is substantially defined by said volume.

6. The system as recited in claim 5, wherein said parameters are scaled such that resolution of said volume is substantially maximized.

7. The system as recited in claim 5, further comprising a second application, wherein said controller determines whether said second application is substantially defined by said volume.

8. The system as recited in claim 5, wherein said first application is a vehicle.

9. The system as recited in claim 5, wherein said first parameter is battery power usage.

10. The system as recited in claim 5, wherein said second parameter is temperature.

11. The system as recited in claim 5, wherein said third parameter is state of charge.

12. A matrix system for a battery comprising:

a first parameter of power usage;

a first requirement designating a portion of said first parameter;

a second parameter of temperature;

a second requirement designating a portion of said second parameter;

a third parameter of state of charge; and

a third requirement designating a portion of said third parameter, such that said portions of said first, second and third parameters intersect to form a volume.

13. The system as recited in claim 12, wherein a battery is defined by said volume.

14. The system as recited in claim 12, wherein a battery application is defined by said volume.
