Why EV Battery Diagnostics Matter

EV batteries degrade over time. Most EV batteries lose around 1-3% capacity per year, depending on the vehicle model, climate and charging habits. But how do you know if a used EV’s battery is still good? Professional diagnostics measure actual capacity, state of health, and degradation — giving buyers and owners confidence.

Independent EV Battery Testing in Ashbourne, Co. Meath

The battery is the most valuable part of any electric car, and its condition cannot be judged from the dashboard range figure or a test drive. Two cars of the same age and mileage can have very different batteries, depending on how they were charged and driven.
Car Avenue EV & Hybrid gives you an independent answer. We connect professional diagnostic equipment to the car, read the data from the battery management system and report the battery’s state of health (SOH), usable capacity and cell balance in plain English. We do not sell cars, so the report has one purpose: to tell you the truth about the battery.
We are based at Unit 22C, Cookstown, Ashbourne, Co. Meath, close to the M2 and around 20 minutes from Dublin. Customers bring their cars to us from all over Ireland.

Frequently Asked Questions

State of health is the battery’s current usable capacity compared with when
it was new, shown as a percentage. A battery at 85% SOH holds about 85% of
its original energy, which means about 85% of the original range.

The test itself usually takes one to two hours. Your written report is
emailed within 24 hours.

Most popular EVs and plug-in hybrids on Irish roads, including Nissan,
Hyundai, Kia, Volkswagen group, BMW, Renault, Tesla and others. Tell us the
make, model and year when you book and we will confirm.

Yes. Testing is carried out in our workshop, where we have the equipment and
a safe environment for high-voltage work.

I always have a great experience with this garage and would highly recommend them. Dan is very, professional, knowledgeable, and takes the time to explain everything clearly. He genuinely cares about doing the job properly. Adriana is also fantastic—friendly, welcoming, and incredibly helpful throughout the whole process. She kept me updated and made everything easy from start to finish. It's not often you find a garage with such excellent customer service! Thank you both for making everything so straightforward!😊

⭐⭐⭐⭐⭐

Highly recommend. Very professional and accommodating. Couldn’t fault them to a tee. Had my car serviced by a garage up the way and they gave the car back with 4 brake discs and pads needing replacing. Wouldn’t fix for 3 weeks so booked here as the car was booked in for its NCT a few days later and would’ve failed. Will definitely be back. Thanks again Car Avenue.
