Rounding: Engineering outputs round to 2–3 decimal places; discrete material bag/unit counts round up via ceiling.

Worked Example: Engineering Scenario: Battery Cycle Life & LCOS

Calculate lifetime delivered MWh and levelized storage cost ($/kWh) across battery cycles.

  1. Enter your system dimensions, electrical/RF ratings, or environmental conditions.
  2. Evaluate the governing equation: UsablePerCycle = Capacity_kWh × DoD% × RoundTripEff%; LCOS = PackCost / (Cycles × UsablePerCycle).
  3. Inspect the primary design output, supporting allowances, and 3 SVG schematics.
Result: Computes Battery Cycle Life & LCOS via UsablePerCycle = Capacity_kWh × DoD% × RoundTripEff%; LCOS = PackCost / (Cycles × UsablePerCycle).

LiFePO₄ vs. NMC Battery Cycle Life, Depth of Discharge (DoD) & Levelized $/kWh Calculator: inputs, method, and how to read the result

Calculate lifetime delivered MWh and levelized storage cost ($/kWh) across battery cycles.

Choose inputs for the case you are checking

The defaults are illustrative. Replace them with values for your case and keep the units shown beside each field.

  • Nominal Pack Capacity Kwh: Nominal battery bank capacity in kWh.
  • Depth Of Discharge Pct: Usable Depth of Discharge (DoD %; e.g., 85%–90% for LiFePO₄).
  • Rated Cycle Life Count: Rated cycle life to 80% State of Health (e.g., 6,000 cycles LiFePO₄, 2,000 NMC).
  • Round Trip Efficiency Pct: Charge/discharge round-trip efficiency (%).

What the calculation includes

With the default values shown, Levelized Cost of Storage (LCOS) is 0.06 USD / kWh cycled. The calculation follows Battery Cycle Life & LCOS Formula; the formula and variable definitions above show how the inputs combine.

One-input check: With the other defaults held constant, changing Nominal Pack Capacity Kwh from 15 kWh to 17 kWh changes Levelized Cost of Storage (LCOS) from 0.06 USD / kWh cycled to 0.05 USD / kWh cycled. This is a comparison inside the calculator's stated model, not a prediction.

Where to use caution

  • Uses standard NREL, IEEE, ASHRAE, and IRC design equations.
  • Verify final structural, electrical, and mechanical specifications against local building codes.

Scope: Global Engineering & Building Code Standard Check the assumptions and limitations against your situation before relying on the estimate.
