Estimated SOC
TOOLS
SOC Estimator
Estimate battery SOC from OCV and temperature with chemistry-aware OCV-SOC curve fitting.

In LFP plateau region - OCV-SOC unreliable

LFP Note: The flat plateau (3.2-3.3V from 20-80% SOC) makes OCV-SOC lookup unreliable in this region. Consider using coulomb counting for better accuracy.
