Payment Terminal & Retail Hardware worked example

Battery Runtime with terminal charging and test connected load of 6 kW: a worked example in payment terminal & retail hardware

This worked example runs the battery runtime numbers for a tougher week than the baseline: terminal charging and test connected load of 6 kW instead of the typical 12 kW. Estimate battery runtime for payment terminal and retail hardware using production-ready inputs so teams can budget energy cost, compare equipment settings, or include electricity in the quote.

The inputs for this scenario

  • Terminal charging/test connected load: 6 kW (the input this scenario stresses; the baseline uses 12)
  • Battery test runtime: 8 hr (held at the documented default)
  • Blended electricity rate: 0.12 $ / kWh (held at the documented default)
  • Terminals processed during runtime: 1,000 units (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total battery runtime energy cost = battery runtime connected load × battery runtime runtime × blended electricity rate.
  • Battery runtime energy used works out to 48 kWh at these inputs, and this is the headline figure for the scenario.
  • Total battery runtime energy cost works out to 5.76 $ at these inputs.
  • Energy cost per kWh works out to 0.01 $ / piece at these inputs.
  • Hourly battery runtime energy cost works out to 0.72 $ / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where terminal charging and test connected load sits at 12 kW and the headline result is 96 kWh, this scenario comes in 50% below the baseline at 48 kWh.
  • Use it to cost a battery burn-in or charge-cycle run, allocate test energy per terminal, or compare the energy cost of different test durations. 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

  • Battery runtime energy used: 48 kWh (headline result)
  • Total battery runtime energy cost: 5.76 $
  • Energy cost per kWh: 0.01 $ / piece
  • Hourly battery runtime energy cost: 0.72 $ / hr
