Battery Heat Generation Calculator

How Battery Heat Generation works

The displayed equation is Pheat = I²r. Battery Heat Generation uses Current, Internal resistance to report Battery heat.

With the loaded values, battery heat evaluates to 96.00 W. Test one input at a time and save the original case.

Inputs for Battery Heat Generation

Current and Internal resistance belong to Battery Heat Generation. Keep source units with current.

The initial entries illustrate operation only. Use current records, readings, or nameplate values for planning.

Current

Example entry: 80 A.

Internal resistance

Example entry: 0.015 Ω.

Reading the Battery Heat Generation result

This output represents Battery Heat Generation. Use Battery Capacity Fade Calculator.

A numerical answer cannot replace the rating and protection checks for the real equipment.

Measurement and units

Battery calculations depend on chemistry, temperature, age, discharge rate, and the limits of the battery management system. Check prefixes on current.

Normalize units before judging one electrical case against another.

Limits of this calculation

Electrochemical heat can add to resistive heating.

This worksheet does not model every behavior in the surrounding system. Unentered effects remain outside Battery Heat Generation.

A useful Battery Heat Generation comparison

Record battery heat before testing a different current value.

Document the alternate current source.
