Charger Pairing at 99% pairing process efficiency: a worked example

Push pairing process efficiency up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it for electric forklift fleets, lithium upgrades, lead-acid battery rooms, opportunity charging plans, rental fleets, AGVs, pallet trucks, and charger deployment projects.

The inputs for this scenario

  • Battery/charger pairings completed: 32 pairings (unchanged)
  • Charger pairing runtime: 8 hr (unchanged)
  • Pairing process efficiency: 99 % (raised for this scenario; the documented default is 88)

Working through the calculation

  • Applying the documented formula (Raw charger pairing = battery/charger pairings completed รท charger pairing runtime) to the inputs above produces each figure below.
  • At this operating point the engine returns 3.96 units for effective charger pairing, the number this scenario is built around.
  • At this operating point the engine returns 4 units for raw throughput.
  • At this operating point the engine returns 99 % for pairing process efficiency.
  • At this operating point the engine returns 8 hr for charger pairing runtime.

How this compares with the baseline

  • Against the tool's baseline example, where pairing process efficiency sits at 88% and the headline result is 3.52 units, this scenario comes in 12.5% above the baseline at 3.96 units.
  • It computes effective charger pairings per hour by dividing completed pairings by runtime and scaling by process efficiency. 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 charger pairing: 3.96 units (headline result)
  • Raw throughput: 4 units
  • Pairing process efficiency: 99 %
  • Charger pairing runtime: 8 hr
