Professional battery testing for electric vehicles

Electromobility has long been part of everyday life and with it comes the responsibility to safely assess the performance of high-voltage batteries. For car dealerships, workshops and fleet managers, this means creating trust, minimising risks and maintaining vehicle value.

With the TÜV NORD BatteryCheck, we offer you a professional battery test for electric vehicles. Our experts check the state of health of the battery using state-of-the-art diagnostic technology and provide clear, comprehensible results. This allows you to recognise defects at an early stage, avoid expensive consequential damage and ensure the long-term satisfaction of your customers.

Why is a battery test important?

  • The number of registered electric vehicles in Germany is growing and with it the used car market. But how good is the condition of the battery after several years of use?
  • The capacity of the traction battery directly influences range, performance and vehicle value. Factors such as driving behaviour, temperature fluctuations, mileage and charging cycles have a long-term effect on the battery - regular testing is therefore essential.
