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.
Claims14
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.
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.
