Why a fireproof battery cabinet is indispensable for lithium-ion batteries
Lithium-ion batteries have become an integral part of our everyday lives. They are used in e-bikes, tools, photovoltaic storage systems, and many other devices. Despite their advantages, they pose significant risks: damage, overcharging, or improper use can lead to fires, explosions, and the release of toxic gases. Incident reports frequently warn of the difficult-to-control dangers of a "thermal runaway," which causes high temperatures and chain reactions within a very short time.
- Mechanical damage can lead to internal short circuits and uncontrollable fires.
- Overcharging or defects can destroy batteries and trigger fires.
- From 130 °C, a chain reaction ("thermal runaway") occurs, with temperatures exceeding 800 °C.
- Toxic, corrosive smoke (white mist with risk of hydrofluoric acid) upon battery failure – dangerous for people and the environment.
Safe storage in a fireproof battery cabinet protects not only your inventory but also your employees, customers, and emergency responders. A modern fireproof battery cabinet is therefore an integral part of preventive fire protection.
Fireproof battery cabinet according to VDMA 24994: Protection beyond old standards
Many fireproof battery cabinets on the market are based on older standards (e.g., EN 14470-1, EN 1363-1, EN 15659), which were not developed for the specific risks posed by lithium-ion cells. These standards primarily address external fire sources but offer no protection against the internal dangers of chemically unstable batteries. Furthermore, they do not require active safety systems such as sensors or automatic emergency mechanisms.
EN 14470-1- Intended for flammable substances; not suitable for explosions caused by Li-ion batteries.
-
EN 1363-1/EN 15659 - Focus on external fire resistance, not internal cell reactions.
EN 1047-1- Protection of documents and data carriers; not designed for batteries.
The VDMA 24994:2024-08 standard – a protection standard developed by experts
In addition to VDMA 24994 certification, various fire protection classes also play an important role at Bremer Tresor when it comes to the optimal protection of your assets. These classes indicate how long a safe can withstand an external fire and complement the special protection against internal dangers offered by a fireproof battery cabinet compliant with VDMA 24994. The following overview shows which features characterize this protection standard developed by experts.
- Testing under realistic conditions, e.g., with NMC 9-0.5-0.5 cells.
- Protection against explosions, splashes, debris, and flame spread – both for hazards originating inside the fireproof battery cabinet and for fires from the outside.
- Active safety systems – mandatory integration: sensors for temperature and smoke detection, emergency shutdown, automatic door locking, and a connection for gas extraction.
- Safety measures for operating errors – such as visual and acoustic alarms as well as an automatic door-closing mechanism should the fireproof battery cabinet be left open inadvertently.
Only with such a tested fireproof battery cabinet are you prepared for real-world dangers. Tests show that temperatures above 1200 °C and destructive explosions are possible in the event of battery failure – only a VDMA 24994 fireproof battery cabinet is prepared for this. Such safes are therefore also an important argument when dealing with insurers and authorities.
EN 1047 but have been specifically adapted to the requirements of the VDMA standard. However, the comprehensive tests according to VDMA 24994 are the most critical for battery-related hazards.What a fireproof battery cabinet from Batrea provides
Our fireproof battery cabinets are specially developed for the safe storage and charging of lithium-ion batteries. Each fireproof battery cabinet offers not only passive protection via a multi-walled, explosion-proof construction but also numerous active safety features:
- Integrated power sockets: Allow for the simultaneous storage and charging of batteries up to 3000 W per storage level.
- Intelligent diagnostic control panel: Monitors temperature and smoke development, warning with visual and acoustic alarms.
- Automatic door locking: Closes automatically in the event of danger and prevents the escape of flames and gases.
- Ventilation flap with control: Closes in case of danger and protects against the release of toxic gases.
- Connection for external extraction: For additional protection in the event of smoke or gas development.
- Socket types E, F, G: Suitable for international use. (On request)
In this way, our fireproof battery cabinets offer maximum safety and functionality in one system.
Who is a fireproof battery cabinet suitable for?

FAQ
Frequently asked questions
A battery safe is a specially designed security cabinet for the storage and charging of lithium-ion batteries. It provides active and passive protection against explosions, fires, and the release of toxic gases, for example through integrated sensors, ventilation, alarm and extinguishing systems.
Lithium batteries can cause dangerous fires and explosions if damaged or overcharged. A tested battery safe significantly reduces this risk and meets modern fire safety requirements, which is also relevant for insurance companies and authorities. A fireproof battery cabinet reliably protects lithium-ion batteries from the risk of fire and explosion. In the event of a defect or overheating, a so-called thermal runaway can occur, generating temperatures of over 800 °C. The fireproof design prevents flames or toxic gases from spreading uncontrollably. This way, you protect not only your batteries but also your employees, customers, and inventory.
VDMA 24994:2024-08 is the latest safety standard for battery storage cabinets. For the first time, it takes into account the specific risks posed by lithium cells, including thermal runaway, internal explosions, and toxic smoke gases. Safes compliant with this standard offer active protection systems and tested safety against internal and external fires.
Thermal runaway refers to the uncontrolled thermal escalation of a battery. This results in rapid self-heating, decomposition, and potentially an explosion. The resulting temperatures can reach over 800 °C and release toxic gases: a major risk without appropriate protection.
A fireproof battery cabinet according to VDMA 24994 offers protection against internal hazards that can occur with lithium-ion batteries, such as explosions or toxic smoke. Conventional steel cabinets or furniture do not offer this protection and can become a fire load themselves in an emergency. Only tested, fireproof battery cabinets with active safety systems, such as temperature and smoke detectors, are designed for such scenarios.
In principle, both terms describe the same thing: a specially developed safe for the safe storage of batteries. A fireproof cabinet for batteries is designed to safely contain both external fires and internal battery defects. A fireproof battery cabinet according to VDMA 24994, however, goes even further and features integrated sensors, automatic door locking, and connection options for gas extraction systems.
Yes, a fireproof battery cabinet is in many cases equipped with integrated sockets that allow for simultaneous charging and storage. A diagnostic control panel permanently monitors temperature and smoke development. This allows you to charge batteries safely without incurring an increased risk of fire or explosion on your premises.
Our battery safes are suitable for, among others, e-bike shops, workshops, logistics companies, fire departments, public institutions, and industry. Wherever lithium batteries are stored or charged, they offer reliable protection and compliance with standards. A fireproof battery cabinet is suitable for numerous industries: e-bike shops and workshops use it to protect customer batteries, while logistics companies can store large quantities of batteries safely. Fire departments and public institutions use it for mission-critical equipment, and in the industry, energy storage systems such as photovoltaic batteries are reliably secured. Wherever lithium-ion batteries are used, the investment in a tested, fireproof battery cabinet is worthwhile.
