A used EV is mostly a battery. In Germany one testing organisation publishes a price for checking it, one does not, and one has left the business

With a used combustion car you look at the odometer and the service book. With a used electric car, a large share of the value sits in one component you cannot see and cannot assess on a test drive: the traction battery. Mileage says little about it and age only a little more. If you want to know the state of health, you have to have it measured — and that is where the search for a published price begins.

Who publishes a figure

• ADAC, AVILOO PREMIUM — 99 euros — the test box is fitted, the car is then driven normally until the state of charge drops below 10 percent, and an AVILOO certificate follows; the ADAC Schleswig-Holstein page quotes the same price for members and non-members
• ADAC, AVILOO FLASH — 79 euros — the shorter variant without the discharge run, again with no member discount stated
• DEKRA, battery quick test — no published price — 15 minutes, returns the state of health; the page addresses fleet operators and dealers and directs everyone else to a contact form
• TÜV Rheinland, Battery Quick Check — no longer offered — discontinued on 28 February 2025; Hella Gutmann Solutions has carried the name since 1 March 2025
• GTÜ partner workshops, AVILOO FLASH — 31.50 euros per test — partner terms, not consumer prices; 35 euros at the standard rate, plus box rental
• GTÜ partner workshops, AVILOO PREMIUM — 40.50 euros per test — again a partner rate against 45 euros standard; box rental 36 euros a month instead of 40

What is striking is what the 99 euros is said to cover. ADAC Schleswig-Holstein lists it plainly as the price of the Premium test, with 79 euros beside it for Flash. ADAC Nordbayern describes an appointment of about 30 minutes at the test centre with the hardware installation included. ADAC North Rhine-Westphalia writes that for the 99 euros its technicians fit the test box, explain the procedure and, on request, go through the certificate. ADAC Hansa names the Hamburg test centre and describes the box being connected at a full charge, after which the car is driven normally for up to seven days. One number, four descriptions — anyone booking should ask at the test centre whether the AVILOO analysis is inside that price or billed separately.
