Free, private, in one minute.

Drop a BMS export — or type five numbers — and get an independent read on cycling stress, thermal regime, SOC behaviour and degradation versus the global cohort of the Observatory. Every finding is priced in money.

Your data never leaves this browser. The analysis runs locally on this page — nothing is uploaded, no account, no email wall.

Local by design

Other vendors ask you to upload BMS data to their cloud before saying anything. This page computes everything on your machine.

Benchmarked against a public fleet

The cohort behind the percentile is the Observatory — GWh-scale, published, auditable. Not a claimed dataset you cannot see.

Priced in money

A finding without a cost is trivia. Each one carries its order-of-magnitude value so you can rank what to fix.

A path to evidence

The free score is a screening. The paid version is a signed, hash-verifiable report your lender, insurer or supplier can check.
