Battery Thermal Test Throughput at 94% thermal test efficiency: a worked example

Push thermal test efficiency up to 94% and the picture changes. This example computes every intermediate figure at that operating point. a test engineer needs to know whether thermal cycling or thermal performance testing can support the build or validation plan

The inputs for this scenario

  • Completed thermal tests: 72 tests (unchanged)
  • Thermal chamber runtime: 24 hr (unchanged)
  • Thermal test efficiency: 94 % (raised for this scenario; the documented default is 82)

Working through the calculation

  • Applying the documented formula (Raw chamber throughput = completed thermal tests รท thermal chamber runtime) to the inputs above produces each figure below.
  • At this operating point the engine returns 2.82 tests / hr for effective thermal test throughput, the number this scenario is built around.
  • At this operating point the engine returns 3 tests / hr for raw chamber throughput.
  • At this operating point the engine returns 94 % for thermal test efficiency.
  • At this operating point the engine returns 24 hr for thermal chamber runtime.

How this compares with the baseline

  • Against the tool's baseline example, where thermal test efficiency sits at 82% and the headline result is 2.46 tests / hr, this scenario comes in 14.63% above the baseline at 2.82 tests / hr.
  • It computes effective thermal tests completed per hour by derating raw chamber throughput with a real-world efficiency factor. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Effective thermal test throughput: 2.82 tests / hr (headline result)
  • Raw chamber throughput: 3 tests / hr
  • Thermal test efficiency: 94 %
  • Thermal chamber runtime: 24 hr
