Graphite, Anode & Battery Materials Processing worked example

Production Ramp Planner at 56% expected ramp uptime: a worked example in graphite, anode & battery materials processing

Suppose expected ramp uptime falls to 56%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate usable production ramp output for graphite, coated anode material, hard carbon, or silicon-carbon powder using kg per ramp cycle, planned cycles, uptime, and ramp yield.

The inputs for this scenario

  • Accepted output per ramp cycle: 120 kg / cycle (held at the documented default)
  • Planned ramp cycles: 30 cycles (held at the documented default)
  • Expected ramp uptime: 56 % (the input this scenario stresses; the baseline uses 78)
  • Ramp first-pass yield: 72 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross ramp output = accepted output per ramp cycle × planned ramp cycles.
  • Usable ramp output works out to 1,452 kg at these inputs, and this is the headline figure for the scenario.
  • Gross ramp output works out to 3,600 kg at these inputs.
  • Ramp uptime loss works out to 1,584 kg at these inputs.
  • Ramp yield loss works out to 564 kg at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where expected ramp uptime sits at 78% and the headline result is 2,022 kg, this scenario comes in 28.21% below the baseline at 1,452 kg.
  • It computes usable ramp output in kilograms by discounting gross cycle output for expected uptime and first-pass yield. 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

  • Usable ramp output: 1,452 kg (headline result)
