Battery Serialization Workload Time at 14% serialization handling allowance: a worked example

Push serialization handling allowance up to 14% and the picture changes. This example computes every intermediate figure at that operating point. a battery plant needs to schedule serialization work for cells, modules, packs, labels, or rework records

The inputs for this scenario

  • Battery items to serialize: 5,200 items (unchanged)
  • Serialization completion rate: 780 items / hr (unchanged)
  • Serialization handling allowance: 14 % (raised for this scenario; the documented default is 12)

Working through the calculation

  • Applying the documented formula (Base serialization time = battery items to serialize รท serialization completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 7.6 hr for required serialization time, the number this scenario is built around.
  • At this operating point the engine returns 6.67 hr for base serialization time.
  • At this operating point the engine returns 14 % for serialization allowance.
  • At this operating point the engine returns 780 items / hr for serialization completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where serialization handling allowance sits at 12% and the headline result is 7.47 hr, this scenario comes in 1.79% above the baseline at 7.6 hr.
  • It computes the labor and station time, in hours, to serialize a batch of battery items at a given completion rate plus a handling allowance. 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

  • Required serialization time: 7.6 hr (headline result)
  • Base serialization time: 6.67 hr
  • Serialization allowance: 14 %
  • Serialization completion rate: 780 items / hr
