M-02State of Health AI

A health score that knows what is normal.

A battery at 78% can be fine or failing. It depends on its age, its chemistry and how it has been used. State of Health AI scores every battery against what is expected for a pack like it, and tells you which habits took the missing points.

Inside the module

What State of Health AI does

01

SoH without a capacity test

Capacity estimated from normal daily cycles. No need to pull vehicles off the road for full discharge tests.

02

Expected health baseline

Each score is compared with a baseline for the same chemistry, age and duty cycle, so outliers stand out.

03

Cause breakdown

The gap between actual and expected health is split into causes: fast charging, heat, deep discharge, high C-rate.

04

Resistance tracking

Internal resistance trends alongside capacity, which often warn of trouble before capacity drops.

05

Fleet distribution

See the spread of health across the whole fleet and spot batches, suppliers or routes that age faster.

06

Confidence on every score

Scores show a confidence range based on how much clean data the battery has. Thin data means a wider band.

Current path

How it runs

  1. 1

    Learn

    Models are trained on charge and discharge curves across chemistries, then tuned to your packs during the first weeks.

  2. 2

    Score

    Every battery gets a State of Health score and an expected score, refreshed daily.

  3. 3

    Explain

    The difference is broken down by cause, so the next step is obvious: change charging, move routes or plan a replacement.

State of Health AI questions

Straight answers about data sources, hardware, accuracy and setup. Ask our team for anything else.

How is this different from the SoH my BMS reports?

Many BMS units report a fixed or slowly stepped SoH figure. We estimate it independently from voltage and current behaviour, and compare it against an expected baseline.

How long before scores are reliable?

Scores appear within days. Confidence tightens over the first three to six weeks as the model sees enough full and partial cycles.

Does it work for lead-acid batteries?

Yes, with a separate model. Lead-acid scores rely more on resistance and voltage sag than on coulomb counting.
