E-Rickshaw Battery SoH Calculator
Estimate state of health for a e-rickshaw battery from age, cycling pattern and depth of discharge.
How healthy is your e-rickshaw battery? India's 2M+ e-rickshaws historically ran lead-acid packs lasting 6–12 months; the LFP upgrade costs 3× upfront but survives 4–6× the cycles — the TCO question every driver asks. This estimator combines cycle wear (equivalent full cycles vs the chemistry's rated life at your depth of discharge) with calendar aging to give e-rickshaw owners and fleet financiers a screening SoH figure — confirm with a measured capacity test.
SoH = 100% − cycle fade (20% × EFC ÷ rated cycles) − calendar fade (1.5%/yr for LFP (LiFePO₄)). Screening model — a measured capacity test (see the capacity-test tool) always beats an estimate.
Engineering estimate from published standards and typical equipment data. Site conditions, equipment datasheets and measured data govern the real result — confirm with a qualified engineer.

- ✓Years-to-80% forecast for replacement planning
Frequently asked questions
What does state of health (SoH) actually mean?+
SoH is today's usable capacity as a percentage of nameplate: a 100 Ah battery measuring 85 Ah is at 85% SoH. It declines through cycle wear (energy throughput) and calendar aging (time and temperature). 80% is the conventional end-of-life for most applications — usable, but with shrinking margins.
How accurate is an estimated SoH versus a real test?+
Estimation from age and usage lands within ±5–10% for typical duty — good for planning, not for warranty claims. A measured capacity test (full discharge at rated current) is the ground truth; use the estimate to decide when testing is worth the effort.
What degrades batteries fastest?+
Heat above 35°C (roughly doubles aging per 10°C), deep discharges (100% DoD can cost 3–4× the cycle life of 50% DoD), sustained full charge (calendar aging accelerates at high voltage), and fast charging when hot. Address the top one in your duty and lifespan visibly improves.
Is the E-Rickshaw Battery SoH Calculator valid for my exact battery model?+
It uses chemistry-class parameters (cycle rating, calendar fade, DoD exponent) typical of quality cells. Premium cells beat the defaults somewhat; bargain cells underperform them. For fleet decisions, calibrate against one measured capacity test and the model tracks well after that.
