The following image illustrates the battery test system workflow. It includes example roles as well, such as design engineers, test engineers, and integrators:



The design engineers specify the devices that need to be tested (the DUTs) as well as the tests to be run on them. Integrators and test engineers then take these requirements, and using the Web UI, create a custom UI that captures the various elements of test environment such as the DUTs, test stations, and the I/O signals to monitor. The lab manager then uses the custom UI to create the actual test plans. A test plan is a combination of one or more DUTs, a test, and a test station. The Operator then executes the test plans and the design engineer evaluates the results.

Additional terms are defined as follows:

  • Test Sequence—A reusable test (created in TestStand and VeriStand Stimulus Profile Editor) used to test DUT(s) in the test station.
  • DUT Model—A specific battery pack, module, or cell to test.
  • Test Plan—A specific combination of a parameterized test sequences to be run on a specific DUT on a specific test station. Refer to Architecture of Test Plans in the Battery Test System Web UI for more information.
  • Test Plan Template—A base test plan that can be used to create a custom test plan.
