Battery Traceability Coverage at 72% required traceability coverage threshold: a worked example

Suppose required traceability coverage threshold falls to 72%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate traceability coverage from serialized battery units with complete genealogy, total units built, and the coverage target.

The inputs for this scenario

  • Battery units with complete build genealogy: 9,850 units (held at the documented default)
  • Total battery units built: 10,000 units (held at the documented default)
  • Required traceability coverage threshold: 72 % (the input this scenario stresses; the baseline uses 99.5)

Working through the calculation

  • The calculation starts from the formula this tool documents: Traceability coverage = units with complete genealogy รท total units built.
  • Traceability coverage works out to 98.5 % traceability at these inputs, and this is the headline figure for the scenario.
  • Traceability gap to requirement works out to -26.5 points at these inputs.
  • Units with complete genealogy works out to 9,850 units at these inputs.
  • Total units built works out to 10,000 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where required traceability coverage threshold sits at 99.5% and the headline result is 98.5 % traceability, this scenario lands almost exactly on the baseline at 98.5 % traceability.
  • It divides units with complete genealogy by total units built to give coverage percent, then shows the gap to your required threshold. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Traceability coverage: 98.5 % traceability (headline result)
  • Traceability gap to requirement: -26.5 points
  • Units with complete genealogy: 9,850 units
  • Total units built: 10,000 units
