New testing requirements for lithium-ion battery safes with VDMA 24994

Lithium-ion batteries are powerful, but they also carry serious risks. During charging, they can catch fire or explode, releasing toxic smoke, damaging your premises and endangering your staff.
For years, there were no clear regulations for the safe storage and charging of these batteries. As incidents increased, one crucial question remained unanswered: how do you know if a battery safe is truly safe? That’s why the VDMA 24994 safety requirements were developed. What began as testing criteria has now grown into an official certification by ECB-S.
What is VDMA 24994?
VDMA 24994 defines the testing requirements for battery cabinets. Only cabinets that pass rigorous practical tests with lithium-ion batteries receive an ECB-S certificate.
Testing can only be carried out by accredited laboratories. In Europe, there are just two: MPA Dresden (Germany) and GryfitLab (Poland), both recognised by ECB-S.. This guarantees that every certified safe is tested using the same strict and reliable method — ensuring the certificate’s credibility.
What does the VDMA 24994 test involve?
To receive the certificate, a battery safe must withstand extreme conditions. The test simulates a thermal runaway — a scenario where batteries overheat and catch fire. The safe is fitted with sensors to assess whether:
- Flames remain contained
- Doors stay closed during an explosion
- Internal temperature stays below 150 °C
Only if the safe meets all these criteria will it receive the certificate. Read more about battery fires and the risks involved.

Is Batteryguard XL tested according to VDMA 24994?
Absolutely. The Batteryguard XL has been successfully tested and is officially certified. This proves the safe meets the highest safety standards for lithium-ion battery storage. View our certified battery safes.
Why is the VDMA 24994 test important for your business?
A battery fire can bring everything to a halt. You risk major property damage, business disruption, evacuation of nearby buildings and even injury to employees. The consequences are severe — and often hard to predict.
That’s why VDMA 24994 matters. It shows that a battery safe has been thoroughly tested for fire and explosion risks — and prevents further damage. Insurance companies are also becoming more strict. In many cases, they now require that lithium-ion batteries be stored and charged in a certified battery safe.
Towards a European standard
The VDMA 24994 testing requirements are not a standalone solution. It’s currently being used as the basis for a new European standard for lithium-ion battery storage.
That standard is under development, but formal adoption may take years. In the meantime, VDMA 24994 serves in practice as the key reference for safe battery safes. Want to stay ahead of future regulations? Then a certified battery safe is the smart choice.
