Cell Formation Energy Cost with formation equipment load of 480 kW: a worked example

This worked example runs the cell formation energy cost numbers for a tougher week than the baseline: formation equipment load of 480 kW instead of the typical 950 kW. Estimate electricity cost for battery cell formation from connected load, runtime, energy rate, and cells processed.

The inputs for this scenario

  • Formation equipment load: 480 kW (the input this scenario stresses; the baseline uses 950)
  • Formation runtime: 18 hr (held at the documented default)
  • Blended electricity rate: 0.12 $ / kWh (held at the documented default)
  • Cells processed: 21,600 cells (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Formation energy cost = formation equipment load × formation runtime × blended electricity rate.
  • Total formation energy cost works out to 994 $ at these inputs, and this is the headline figure for the scenario.
  • Formation energy used works out to 8,640 kWh at these inputs.
  • Formation energy cost per cell works out to 0.05 $ / cell at these inputs.
  • Formation energy cost per hour works out to 55.2 $ / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where formation equipment load sits at 950 kW and the headline result is 1,967 $, this scenario comes in 49.47% below the baseline at 994 $.
  • Use it to budget formation energy, compare formation recipes or equipment, and feed an accurate energy line into the cell cost model. 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

  • Total formation energy cost: 994 $ (headline result)
  • Formation energy used: 8,640 kWh
  • Formation energy cost per cell: 0.05 $ / cell
  • Formation energy cost per hour: 55.2 $ / hr
