Battery Copilot. An AI that speaks batteries.

Ask about rules, standards, test reports and pack design in plain English. Battery Copilot runs on PassReady's own self-hosted language model, trained on battery and power-electronics knowledge — so you get focused answers, and your data is not sent to outside AI companies.

Try an example question

Does our 48V e-scooter pack need an EU battery passport?

Yes. A 48V e-scooter pack is a light means of transport (LMT) battery, so it needs a digital battery passport for every unit sold in the EU from 18 February 2027.

From your vault: your UN 38.3 report is valid, but there is no EN 50604-1 safety report for this model yet. You will also need material and origin data from your cell supplier.

  • EU Reg. 2023/1542, Art. 77
  • UN38.3_Report_48V.pdf · p. 1
  • Supplier request · pending

Why a battery-specific model

Built for battery questions, not general chat.

General chatbots guess when questions get technical. Battery Copilot is trained for the work your quality and engineering teams actually do.

  • Trained on batteries and power

    Built on battery chemistries, cell and pack design, BMS, power electronics, test standards and battery regulations — not general internet chat.

  • Self-hosted and private

    The model runs on our own servers. Your test reports and supplier data are not sent to third-party AI providers.

  • Answers you can check

    Every answer points to its source — the page in your test report or the article in the regulation.

  • Knows your products

    Copilot reads the documents in your vault, so answers are about your packs, not batteries in general.

What you can ask

From regulations to cell data.

Compliance

  • “Does this pack need an EU battery passport?”
  • “Which rules apply if we start selling in Germany?”
  • “What is missing before we can apply for BIS?”

Testing & certification

  • “Summarise this UN 38.3 report and flag any failed tests.”
  • “Which IEC 62619 tests does our 5 kWh unit still need?”
  • “When do our certificates expire?”

Engineering

  • “Why is one cell group running hotter in this thermal test?”
  • “LFP or NMC for a 48V swappable 3W pack?”
  • “Explain the capacity fade in this cycle-life report.”

Suppliers & data

  • “Which cell supplier data is still missing for the passport?”
  • “Draft a data request to our cell supplier.”
  • “Compare datasheets from two cell suppliers.”

Battery Copilot helps your team work faster. It does not replace accredited labs, notified bodies or legal advice — always confirm critical decisions.
