Summary Electric vehicle sales are surging, but the used EV market struggles with buyer distrust, primarily battery longevity concerns. Austrian company AVILOO addresses this with its battery testing technology. CEO Marcus Berger explains their PREMIUM test for consumers, requiring a full charge/discharge cycle, and the quicker FLASH test for dealerships. Both utilize OBD-II data and AVILOO's extensive database to provide accurate, standardized battery health certificates. These have significantly boosted used EV sales by instilling transparency and trust, leading to faster sales and higher prices. AVILOO now offers a financial guarantee, backing its battery health assessments. This technology is widely adopted in the UK remarketing industry, with plans for further development.
AVILOO has created its own data logging device to measure EV battery health. AVILOO Electric vehicles have entered the mainstream in key regions, with new EV sales surpassing a 20% market share in the EU and reaching 30% in the UK . But second-hand values have been suppressed by buyer concerns. One of the key worries is battery age. Although the fearmongering about needing to replace EV batteries after three years has proven to be mostly mythical , the true capacity of a second-hand battery remains in question. Austrian business AVILOO reckons it has the answer with its battery testing technology. I talked to CEO Marcus Berger about how his company could lubricate the second-hand EV market.
“We built AVILOO because the used EV market had a structural trust problem,” says Berger. The typical experience people had with smartphones was that batteries were depleted after a few years, and many thought EVs would be the same. Spending $100 swapping packs on a phone is annoying, but when it costs 100x that in an electric car, it would be a disaster. When AVILOO was founded in 2018, this concern made people wary of buying an electric car second hand. “Our aim was to solve that structural trust problem in the used EV market.”
AVILOO’s foundation is a product for end users called the PREMIUM Battery Test, which I recently tested on my own car . To build this system, the company needed data that it could analyze to provide a battery health reading. “Getting access to data from all different models was a challenge because there are no standardized communication protocols,” explains Berger. “We use the OBD-II interface. We built the logging hardware to give us access to that data. We needed to understand all the current, voltage and temperatures.” AVILOO collects thousands of data points every millisecond.
The certificate my car received after the AVILOO PREMIUM Battery Test. James Morris After three years, AVILOO had created a data collection device and a certificate the user obtains at the end of the process to guarantee the battery state of health. Testing my car with the PREMIUM Battery Test involved installing an OBD-II port in my own Tesla, which was easy after watching some YouTube videos, and then plugging in the AVILOO device. I then had to charge the car to 100%…
