EV Battery SOH & Complete Global Curve Reconstruction

Upload your SFT and FFT files to analyze battery health and reconstruct the complete global discharge curve.

Same-Rate Analysis

Upload a partial SFT and a complete FFT captured at the same C-rate to predict per-module SOH and reconstruct the full discharge curve.

Weakest Module Voltage Curve

The pack's weakest module's discharge curve: predicted (reconstructed from the uploaded SFT) vs the complete real curve (from the uploaded FFT). Circles mark predicted capacity/SOH at 3.25V and 2.5V; triangles mark the actual values.

Per-Module Analysis

Splits the pack's 108 cells into its 9 modules (12 cells each). "Predicted" comes from the uploaded SFT file via the module SOH model; "Actual" is measured or estimated directly from the uploaded FFT file's full discharge curve. Each bar shows SOH% and capacity (Ah); hover for the source.

Cross-Rate Tool

Cross-Rate Prediction: 1.0C SFT → 0.3C SOH

Upload only a 1.0C SFT to predict every module's SOH/capacity at 0.3C using a dedicated cross-rate model. Optionally upload a 0.3C FFT as well to validate the prediction against real ground truth.
