Abstract

Certain embodiments are described that provide a method and computer readable media for testing battery cells. A unique identifier (e.g., barcode) is affixed to a battery cell which allows it to be tracked across separate tests as a cell, in a module, string, pack, etc. Using a GUI, the unique identifier is recorded in a database along with at least a battery cell manufacturer and a battery cell model. A designation of the particular tester channel or module or string location is entered into the database in association with the unique identifier. Test results of the first test are electronically transferred from the first tester to the database along with the corresponding channel designations.

Claims (64)

1. A method for testing battery cells comprising:

assigning a unique identifier to an individual battery cell;

recording the unique identifier in a database along with at least a battery cell manufacturer and a battery cell model;

providing to a first tester at least one individual cell test for the individual battery cell in a particular channel of the first tester;

receiving a designation of the particular channel in association with the unique identifier;

electronically receiving test results of the individual cell test from the first tester for storage in the database along with the corresponding channel designations;

storing the test results of the individual cell test from the first tester in the database in association with the unique identifier;

providing at least one module test on the individual battery cell and other battery cells in a module;

electronically receiving test results of the module test;

storing the test results of the module test in the database;

mounting the module, along with other modules, into a particular string location in a string;

providing at least one string test for the individual battery cell and other battery cells;

electronically transferring test results of the string test to the database; and

storing the test results of the string test in the database in association with the unique identifier;

mounting the string, along with other strings, into a particular pack location in a pack;

providing at least one pack test for the battery cell and other battery cells;

electronically transferring test results of the pack test to the database; and

storing the test results of the string test in the database in association with the unique identifier.

2. The method of claim 1 further comprising:

providing in a GUI a display chart of test results, including at least charge and discharge characteristics.

3. The method of claim 1 wherein the database is a NoSQL database with a dynamic structure.

4. The method of claim 1 wherein the unique identifier is a bar code.

5. The method of claim 1 further comprising:

identifying a test abnormality from the module test;

comparing the test results of the module test with the test results of the individual cell test; and

determining whether the test abnormality is caused by the individual cell or the module.

6. The method of claim 1 further comprising:

storing a digital representation of a test profile of the individual cell test and of a test profile of the module test in the database; and

loading the digital representation of the individual cell test from the database into the first tester.

7. The method of claim 2 further comprising:

providing a filter module in the GUI; and

changing the chart of test results in real time in response to changes in filter parameters in the filter module.

8. A non-transitory, computer readable media containing computer readable instructions for testing battery cells, comprising instructions for:

assigning a unique identifier to an individual battery cell;

recording the unique identifier in a database along with at least a battery cell manufacturer and a battery cell model;

providing to a first tester at least one individual cell test for the individual battery cell in a particular channel of the first tester;

receiving a designation of the particular channel in association with the unique identifier;

electronically receiving test results of the individual cell test from the first tester for storage in the database along with the corresponding channel designations;

storing the test results of the individual cell test from the first tester in the database in association with the unique identifier;

providing at least one module test on the individual battery cell and other battery cells in a module;

electronically receiving test results of the module test;

storing the test results of the module test in the database;

mounting the module, along with other modules, into a particular string location in a string;

providing at least one string test for the individual battery cell and other battery cells;

electronically transferring test results of the string test to the database; and

storing the test results of the string test in the database in association with the unique identifier;

mounting the string, along with other strings, into a particular pack location in a pack;

providing at least one pack test for the battery cell and other battery cells;

electronically transferring test results of the pack test to the database; and

storing the test results of the string test in the database in association with the unique identifier.

9. The non-transitory, computer readable media of claim 8 further comprising instructions for:

storing a digital representation of a test profile of the individual cell test and of a test profile of the module test in the database; and

loading the digital representation of the individual cell test from the database into the first tester.

10. The non-transitory, computer readable media of claim 8 further comprising:

providing in a GUI a display chart of test results, including at least charge and discharge characteristics.

11. The non-transitory, computer readable media of claim 10 further comprising instructions for:

providing a filter module in the GUI; and

changing the chart of test results in real time in response to changes in filter parameters in the filter module.

12. The non-transitory, computer readable media of claim 8 wherein the database is a NoSQL database with a dynamic structure.

13. The non-transitory, computer readable media of claim 8 wherein the unique identifier is a bar code.

14. The non-transitory, computer readable media of claim 8 further comprising instructions for:

identifying a test abnormality from the module test;

comparing the test results of the module test with the test results of the individual cell test; and

determining whether the test abnormality is caused by the individual cell or the module.
