Battery Runtime Calculator

Estimate runtime from battery capacity, state of charge, efficiency and a constant load.

01 / Inputs

Battery runtime

02 / Result

Estimated battery runtime

Waiting for input

Enter battery, state-of-charge and load assumptions.

Method and boundaries

Deliverable energy = voltage × capacity × (starting SoC − ending SoC) × state of health × discharge efficiency. Runtime = deliverable energy ÷ load.

This is a constant nominal-voltage and constant-load estimate. It does not model Peukert effect, temperature, battery chemistry, BMS limits, voltage cutoff, aging curves or code compliance.

Deliverable energy = voltage × capacity × (starting SoC − ending SoC) × state of health × discharge efficiency. Runtime = deliverable energy ÷ load.

This estimate assumes constant nominal voltage and load. Peukert effect, temperature, chemistry, BMS limits, voltage cutoff, aging and code compliance are not inferred. SRC-010 · model 1.0.0 · user-input-v1.
