A method of repairing a used battery pack from an electric vehicle include removing the battery pack from the vehicle. Battery tests are performed on at least some of the plurality of batteries and a battery test result for each of the batteries tested are obtained and stored in a database. A plurality of replacement batteries are tested and test results for each of the replacement batteries are stored in the database. The battery test results from the database are retrieved and used to create a refurbished battery pack. An apparatus includes a database for storing test results.
1. A method of repairing a used battery pack from an electric vehicle, comprising: removing the battery pack from the vehicle, the battery pack comprising a plurality of batteries;performing battery tests with a battery tester on at least some individual batteries of the plurality of batteries, obta
1. A method of repairing a used battery pack from an electric vehicle, comprising: removing the battery pack from the vehicle, the battery pack comprising a plurality of batteries;performing battery tests with a battery tester on at least some individual batteries of the plurality of batteries, obtaining a battery test result for the batteries tested and storing the battery test results in a database;obtaining a plurality of replacement batteries;performing battery tests with a battery tester on at least some individual batteries of the plurality of the replacement batteries, obtaining a test result for the replacement batteries and storing the battery test results in the database;retrieving the battery test results from the database;identifying replacement batteries based upon the retrieved battery test results for use in forming a refurbished battery pack; andrefurbishing the battery pack with identified replacement batteries based upon the step of identifying. 2. The method of claim 1 wherein the step of identifying batteries comprises applying selection criteria to the battery test results stored in the database. 3. The method of claim 2 wherein the selection criteria is based upon an adjustable parameter of the batteries, the method further including adjusting the adjustable parameter of at least one battery. 4. The method of claim 2 wherein the selection criteria is based upon an adjustable parameter of the batteries, wherein the selection criteria applies a greater weighting function to a non-adjustable parameter relative to a nonadjustable parameter. 5. The method of claim 2 wherein the selection criteria includes comparing parameters of batteries to each other and identifying parameters which are within a selected range. 6. The method of claim 2 wherein the selection criteria is based upon multiple parameters of the batteries. 7. The method of claim 1 including storing battery identification information in the database which is associated with a test result for a particular battery. 8. The method of claim 1 including implementing the database in a computer memory. 9. The method of claim 1 wherein the battery test comprise applying a forcing function to a battery and observing a result. 10. The method of claim 1 wherein the batteries comprise individual cells. 11. The method of claim 1 wherein the batteries comprise groups of cells. 12. The method of claim 1 wherein performing battery tests on the batteries in the battery pack is performed prior to removing the battery pack from the vehicle. 13. The method of claim 1 wherein performing battery tests on the batteries in the battery pack is performed subsequent to removing the battery pack from the vehicle. 14. The method of claim 1 wherein the replacement batteries are obtained from another battery pack. 15. The method of claim 1 wherein the replacement batteries comprise new batteries. 16. The method of claim 1 including identifying a configuration of batteries for placement in the refurbished battery pack based upon the battery test results. 17. The method of claim 1 including implementing the step of identifying in a computer. 18. An apparatus for use in refurbishing a used battery pack from the electric vehicle, comprising: battery test circuitry configured to perform battery tests on individual batteries in the used battery pack;a database configured to contain battery identification information of a plurality of individual replacement batteries and at least one associated battery parameter obtained from the battery test circuitry;a selection criteria which identifies individual replacement batteries for use in creating a refurbished battery pack; anda controller configured to retrieve information from the database, apply the selection criteria and responsively provide selection information output which indicates which of the individual replacement batteries identified in the database are suitable for use in creating a refurbished battery pack. 19. The apparatus of claim 18 wherein the selection criteria includes comparing parameters of batteries to each other and identifying parameters which are within a selected range. 20. The apparatus of claim 19 wherein the selection criteria is based upon an adjustable parameter of the batteries, the controller further configured to adjust the adjustable parameter of at least one battery. 21. The apparatus of claim 19 wherein the selection criteria is based upon an adjustable parameter of the batteries, wherein the selection criteria applies a greater weighting function to a non-adjustable parameter relative to the adjustable parameter. 22. The apparatus of claim 18 wherein the selection criteria is based upon multiple parameters of the batteries. 23. The apparatus of claim 18 wherein the database includes battery identification information associated with a test result for a particular battery. 24. The apparatus of claim 18 wherein the battery test comprises applying a forcing function to a battery and observing a result. 25. The apparatus of claim 18 wherein the batteries comprise individual cells. 26. The apparatus of claim 18 wherein the batteries comprise groups of cells. 27. The apparatus of claim 18 wherein the selection information output includes information identifying a configuration of batteries for placement in the refurbished battery pack based upon the battery test results.
