In a world where lithium-ion batteries are playing an increasingly prominent role across various sectors—from automotive to construction and demolition—the safe charging of these batteries has become more crucial than ever. Fires caused by lithium-ion batteries are becoming more frequent, and with the introduction of the VDMA 24994 standards, we are making significant progress in protecting against the risks of battery fires.
What is VDMA 24994?
VDMA 24994 is a document issued by the VDMA (Mechanical Engineering Industry Association). This document specifies the testing requirements for fire-resistant storage cabinets designed for lithium-ion batteries. This is critical in a market where many different storage solutions claim to be safe.
The document applies to removable/portable lithium-ion batteries weighing 25 kg or less, which can be detached from equipment to allow separate charging or replacement with a charged battery. Active charging of the lithium-ion batteries is also possible within the cabinet.
Why is VDMA 24994 Important?
The need for a clear testing methodology like the VDMA 24994 arises from practical concerns. Many existing solutions, such as EN 14470-1 chemical cabinets, do not provide the necessary safety for battery fires. Incidents where batteries become extremely hot and ignite can result in flames escaping the cabinet and doors flapping open, leading to severe consequences. This creates considerable uncertainty and risks for businesses and insurers. Consequently, insurers have long required that lithium-ion batteries be stored and charged in a secure storage solution.
Key Requirements of VDMA 24994
VDMA 24994 sets explicit performance requirements for lithium-ion battery storage safes. These safes must withstand certain temperatures and the forces of potential explosions. Additional safety requirements include ensuring that the doors of the battery safe automatically close after a set period to contain a fire within the cabinet. This can be achieved through alarms that alert if the doors remain open or through self-closing doors. The goal is to keep a battery fire contained within the safe and prevent it from spreading.
Safe-ion Safes
Safe-ion safes have been tested with lithium-ion batteries by MPA Dresden during the development of VDMA 24994 and successfully contain battery fires within the safe. Safe-ion safes thus offer proven protection for your business premises and surroundings. For more information, please visit our safes page.
