Know What You're Really Buying.

Is your EV battery as healthy as the seller claims? A degraded battery won't show a warning light — but it will silently cut your real-world range. PAD tests your battery's true SOC and SOH on site — and every test comes with an official Aviloo certificate, the independent third-party seal used by manufacturers, insurers and dealers across Europe.

Understanding Your Battery

SOC vs SOH.

Two numbers. Only one of them tells you what your battery is actually worth.

SOC
State of Charge

SOC is your battery's fuel gauge — how full it is right now, as a percentage. It goes up when you charge, down when you drive. It tells you how far you can go today, but nothing about the long-term health of the battery.

Example: 80% SOC means the battery is 80% full at this moment. Charge it to 100% and it reads 100%. This number is always changing.
SOH
State of Health

SOH is the critical long-term figure — it compares the battery's current maximum capacity against its original factory capacity. A battery with 80% SOH can only ever hold 80% of its original energy, no matter how fully you charge it. This is what determines real-world range.

Example: A Nissan Leaf sold as having a 150-mile range, but with 75% SOH, will only deliver around 112 miles at best. That's a hidden range loss of 38 miles — invisible without testing.
PAD measures both. Our test gives you the exact SOH figure — the number that determines what the battery is worth and how far it will take you — along with current SOC. Both appear on your official Aviloo certificate, issued with every test.
Included in Your £79 Test

What You Get.

SOC Measurement

Precise State of Charge reading at time of test, collected directly from the battery management system — not estimated from the dashboard gauge.

About the Technology

What Is the Aviloo Certificate Included With Every Test?

Aviloo is a European independent battery certification body used by vehicle manufacturers, insurers, fleet operators and major used EV dealers. Every PAD EV battery test includes an Aviloo certificate — the independent third-party seal that confirms the test result is objective and professionally verified.

The Aviloo certificate is not simply a printout from our own system. It is a recognised, independently verified document with a unique certificate ID — verifiable by any buyer or insurer, and trusted across Europe.

If you are buying a used EV, the PAD test certificate gives you the same independent credibility as an HPI check. If you are selling, it supports your asking price and gives buyers the confidence to commit.

  • Certificate recognised by manufacturers, insurers and dealers across Europe
  • Standardised independent certification — not a self-issued report
  • Unique certificate ID — independently verifiable
  • Accepted by major EV insurers for battery condition evidence
  • Supports negotiation when buying, supports asking price when selling
  • PAD is certified to issue official Aviloo certificates

Who It's For

Why You Need This Test.

🔍

Buying a Used EV

Battery degradation is the single biggest hidden cost risk in a used EV purchase. The car may drive perfectly but silently deliver 30% less range than advertised. The PAD test gives you an independently certified SOH figure — backed by an official Aviloo certificate — to negotiate with or walk away from.

💰

Selling Your EV

A PAD battery health certificate supports your asking price and answers the first question every serious EV buyer asks. Sellers with a certificate close deals faster and face less negotiation — the document does the trust-building for you.

🛡

Insurance & Peace of Mind

Some EV insurers and finance providers require evidence of battery condition. Even without an external requirement, a PAD battery test gives you the facts to plan around — and the Aviloo certificate as a permanent record.

📊

Understanding Your Own Battery

Already own an EV and wondering how it's degrading over time? An annual PAD battery test tracks your SOH year on year — so you can see how usage, charging habits and temperature affect your battery over its lifetime. Each test produces a fresh Aviloo certificate as a dated record.

Common Questions

EV Battery FAQ.

An EV battery health check measures two key figures: State of Charge (SOC) — how full the battery is right now — and State of Health (SOH) — what percentage of the battery's original capacity remains. SOH is the critical number: a new EV battery starts at 100% SOH and degrades over time and cycles. A battery at 75% SOH holds significantly less charge than when new. PAD carries out the battery health test on site and measures both figures to a professional standard.
State of Charge (SOC) is like a fuel gauge — it tells you how full the battery is at this moment, expressed as a percentage. It changes every time you drive or charge. State of Health (SOH) is the more important long-term figure — it compares the battery's current maximum capacity against its original factory capacity. A battery with 80% SOH can only hold 80% of the energy it held when new, regardless of how fully you charge it. SOH degrades gradually over years of use. PAD measures SOH professionally on site, with every result independently certified.
Aviloo is a European EV battery testing specialist whose certified process is used by vehicle manufacturers, insurers, and used EV dealers to produce a standardised, independent battery health certificate. An Aviloo certificate is not just a printout from a diagnostic tool — it is a recognised, third-party verified document that can be shared with insurers, prospective buyers, or fleet managers to prove the battery's condition. It adds real resale value and peace of mind that a simple OBD scan cannot provide.
Battery degradation is the single biggest hidden cost risk when buying a used EV. Unlike engine faults, a degraded battery rarely triggers a warning light — the car drives normally but simply cannot travel as far. A seller may advertise a car with a 150-mile range, but if the battery SOH is 75%, you may only achieve around 110 miles. The Aviloo certificate gives you an independent, certified figure to negotiate with or walk away from. It is the EV equivalent of a pre-purchase mechanical inspection.
Absolutely. Many existing EV owners want to understand their battery's condition for insurance purposes, before a long journey, or simply for peace of mind. The Aviloo certificate is also very useful if you plan to sell your EV — providing a buyer-facing health document that supports your asking price and builds trust instantly.
PAD covers a wide range of popular EVs for battery health testing, including Nissan Leaf, Renault Zoe, Volkswagen ID.3 and ID.4, Hyundai Ioniq 5 and 6, Kia e-Niro and EV6, BMW i3, Tesla Model 3 and Model Y, Audi e-tron, Peugeot e-208, Vauxhall Mokka-e, and many more. Check your vehicle on our coverage page or contact us to confirm before booking.
The PAD EV battery health test takes up to 60 minutes on site. Your official Aviloo certificate is generated and emailed to you directly. The vehicle must remain available throughout the test.
No. The PAD battery health test is entirely passive — it reads data from the battery management system and does not discharge, stress, charge, or modify the battery in any way. Completely non-invasive with no risk to the battery or vehicle warranty.
