TÜV SÜD Battery Testing: Trust in precision under vacuum

How the Memmert VOcool is setting new standards in battery testing

When it comes to the safety and performance of modern energy storage systems, there is no way around the TÜV SÜD battery testing laboratory in Frankfurt. The company is known worldwide for independent quality assurance, research and certification in the field of battery technology – from electromobility to stationary energy systems.

Since early 2025, TÜV SÜD has been relying on the Memmert VOcool for battery testing – the only vacuum drying oven with active cooling available on the market. This opens up new possibilities for precise and reproducible testing under extreme conditions.

Innovation meets application

In daily work, batteries and cell components are tested in the VOcool under low pressure and controlled low temperatures. The aim is to investigate the behaviour and stability of the cells under realistic but demanding environmental conditions.

Two parameters are particularly important here:

  • Pressure and temperature are precisely controlled to reveal even the smallest differences in reaction.
  • The combination of vacuum technology and active cooling is crucial for safe, energy-efficient testing.

This combination makes the VOcool the only device of its kind in the world – and therefore the first choice for applications where precision and safety are top priorities.

The difference is in the details

The VOcool is based on the technology of the proven Memmert vacuum ovens, enhanced with an active cooling system. This means that the chamber temperature can not only be heated up quickly, but also lowered in a controlled manner – a decisive advantage for thermally sensitive materials such as battery cells, electrolytes or sealing materials.

"The combination of vacuum and cooling is unique. For our tests, this is a real game changer." – Florian Jahn, Technical Director, TÜV SÜD Battery Testing GmbH

Why Memmert?

TÜV SÜD Battery Testing relies on Memmert because precision, reproducibility and safety go hand in hand here:

  • Unique technology: active cooling in a vacuum – exclusively from Memmert
  • High energy efficiency thanks to finely tuned control
  • Long-term stability and intuitive operation for reliable test series
  • Made by Memmert – robust, precise and service-friendly

Energy efficiency meets responsibility

With VOcool, TÜV SÜD Battery Testing is not only contributing to the further development of modern batteries, but also to sustainability in the laboratory. Efficient pressure and temperature control saves energy and reduces test cycles – a clear plus for the environment and economic efficiency.

Conclusion

What happens when two innovation leaders work together? A laboratory that redefines the standard.

The Memmert VOcool opens up completely new avenues for TÜV SÜD Battery Testing to make the future of battery technology safer, more efficient and more sustainable.
