System and method for assessing a battery module

A non-transitory computer-readable storage medium embodying programmed instructions which, when executed by a processor, are operable for performing a method comprising:

• performing a battery module functionality test on a plurality of battery cell arrays within a battery module to obtain battery test data for each of the plurality of battery cell arrays;
• determining from the battery test data if a measured parameter for one of the plurality of battery cell arrays deviates from a predetermined threshold for the measured parameter;
• performing a focused secondary battery test on each of the plurality of battery cell arrays that include the measured parameter that deviates from the predetermined threshold;
• and
• qualifying the battery module based on at least one of the battery test data and the focused secondary battery test.

A system for assessing a battery module, the system comprising:

• a plurality of battery cell arrays in the battery module;
• a secondary battery test device configured to be directed at the battery module;
• a controller in communication with the battery module and the secondary battery test device, the controller is configured to:
• perform a battery module functionality test on the plurality of battery cell arrays within the battery module to obtain battery test data for each of the plurality of battery cell arrays;
• determine from the battery test data if a measured parameter for one of the plurality of battery cell arrays deviates from a predetermined threshold for the measured parameter;
• perform a focused secondary battery test on each of the plurality of battery cell arrays that include the measured parameter that deviates from the predetermined threshold;
• and
• qualify the battery module based on at least one of the battery test data and the focused secondary battery test.
