Vehicle diagnostics for privat
How fit is your electric car’s battery really, and what is it still worth? With the TÜV NORD BatteryCheck for private customers, you can obtain an independent, certified assessment of your battery’s condition in just a few minutes — without any dismantling or interference with the vehicle’s systems. Analysed in accordance with the European CARA standard.

In everyday use, the loss of performance is often barely noticeable. But the battery ages gradually:
The problem: neither mileage nor age provide reliable information about the battery’s condition. Frequent fast charging, extreme temperatures or poor charging habits put a strain on the battery — regardless of how little the vehicle has been driven.
Without an independent measurement, you are buying or selling your vehicle blind.
The TÜV NORD BatteryCheck provides you with exactly that:
an impartial assessment of the battery’s state of health based on real vehicle data, for €89.90.
You will receive:
No estimates. No manufacturer’s figures. Just real data.

The inspection is carried out quickly, safely and without any work being done on your vehicle:
What this means for you:
Whether it’s a Tesla, an ID. model, a BMW, a Hyundai or a plug-in hybrid:
The TÜV NORD BatteryCheck is compatible with around 1,300 vehicle and model variants – more than any other independent provider in Europe.
A professional battery check provides you with reliable data on the state of health (SOH) of your high-voltage battery. Precisely because the battery is the most expensive component in an electric car, it is well worth having it checked in many specific situations.
A battery check before purchase provides clarity on the actual condition of the high-voltage battery. It allows you to identify capacity loss, hidden signs of ageing or anomalies in the battery management system at an early stage. This helps you avoid costly mistakes and ensures you have a solid basis for negotiating the purchase price.
An independent battery test allows you to document the current condition of your vehicle’s battery in a transparent and verifiable manner. This builds trust with potential buyers, reduces the need for further enquiries and can have a direct positive impact on the achievable selling price. The test report can also be uploaded to sales portals.
If you notice a significant drop in your electric car’s range, a battery check will provide the answers you need. You’ll find out whether the problem is actually down to the battery (e.g. due to a loss of capacity) or whether external factors such as driving style, temperature or software are playing a part.
Regular battery checks help you keep track of the condition of your high-voltage battery over time. You can spot any changes at an early stage, take targeted action to address them, and safeguard the long-term value and performance of your electric vehicle.
Whether you’re looking to buy a second-hand electric car, want to sell yours, or simply want to know how well your vehicle is still performing: with the TÜV NORD BatteryCheck, you’ll know exactly where you stand in just a few minutes — certified, independent, and easy to understand.
