Battery Degradation Calculator — Estimate remaining EV battery capacity after years of use. Enter Degradation rate (%/year), Years of use to get an instant, accurate result.

공식

Remaining capacity % = 100 − (annual degradation rate % × years). Degraded % = 100 − remaining %.

단계별 안내

Enter the Degradation rate (%/year).
Enter the Years of use.
Click Calculate to see your result instantly.

실제 예시

Example: With Degradation rate (%/year) = 2.3, Years of use = 5, the Battery Degradation Calculator gives Remaining Capacity Percent: 88.5, Degraded Percent: 11.5.

자주 묻는 질문

Is battery degradation actually linear?

Not exactly — real-world degradation is often faster in the first year or two and slows afterward, but a linear rate is a reasonable simplified estimate for planning purposes.

What is a typical annual degradation rate?

Many modern EV batteries degrade around 1.5–2.5% per year, though this varies by chemistry, climate, and charging habits.

What inputs does the Battery Degradation Calculator need?

You'll need to provide: Degradation rate (%/year), Years of use. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.

How accurate is the Battery Degradation Calculator?

The Battery Degradation Calculator applies the formula exactly as calculated — Remaining capacity % = 100 − (annual degradation rate % × years). Degraded % = 100 − remaining %. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.

Is the Battery Degradation Calculator free to use?

Yes, the Battery Degradation Calculator is completely free, requires no signup, and runs instantly in your browser.
