Electric GSE Battery Pack Capacity at 65% pack assembly and test uptime: a worked example

This worked example runs the electric gse battery pack capacity numbers for a tougher week than the baseline: 65% pack assembly and test uptime instead of the typical 90%. Estimate usable electric GSE battery pack output from packs built per cycle, available cycles, test-stand uptime, and battery acceptance yield.

The inputs for this scenario

  • Battery packs completed per build cycle: 4 packs/cycle (held at the documented default)
  • Available battery build cycles: 150 cycles (held at the documented default)
  • Pack assembly and test uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • Battery acceptance test yield: 94 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross battery pack capacity = packs completed per cycle × available battery build cycles.
  • Accepted battery pack capacity works out to 367 battery packs at these inputs, and this is the headline figure for the scenario.
  • Gross battery pack capacity works out to 600 battery packs at these inputs.
  • Packs lost to test or assembly downtime works out to 210 battery packs at these inputs.
  • Packs lost to failed acceptance test works out to 23.4 battery packs at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where pack assembly and test uptime sits at 90% and the headline result is 508 battery packs, this scenario comes in 27.78% below the baseline at 367 battery packs.
  • Use it during capacity planning for an electric GSE program, when quoting pack volumes, or when deciding whether to invest in test throughput versus yield improvement. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Accepted battery pack capacity: 367 battery packs (headline result)
  • Gross battery pack capacity: 600 battery packs
  • Packs lost to test or assembly downtime: 210 battery packs
  • Packs lost to failed acceptance test: 23.4 battery packs
