Flagship solution · Storage and charging
Certified fire-rated cabinets, containers, mobile enclosures and walk-in rooms for storing and charging lithium-ion batteries—from a single e-bike battery to pallet scale. German-made PRIORIT systems, engineered and delivered by Pyralta.
The risk
A technical defect or a handling error during storage or charging can trigger thermal runaway: an uncontrolled release of the stored energy, with fire, projectiles and toxic gases. These are the five causes behind most incidents.
Overheating while charging
Wrong charger or overcharging
Deep discharge
Mechanical damage
High ambient temperature
“From the property insurer's view, lithium batteries must potentially be classified as a hazard.”— Carsten Tormöhlen, Allianz Deutschland AG
Guidance such as VdS 3103 therefore calls for structural or spatial separation—at least 2.5 m from combustible materials where no automatic extinguishing is present—immediate isolation of damaged batteries, and protection against short circuits and heat. Certified containment turns those rules into one simple, inspectable measure.
Where to start
Match what you store—and what you do with it—to the right level of containment.
| Your situation | Your solution | Why |
|---|---|---|
| A few batteries, spares or returns (e-bike, tools, electronics) | PRIOPACK container | 90-minute lined container with absorbing filler—closes the risk in a box |
| Damaged or defective batteries awaiting disposal, or in transit | PRIOPACK-T transport container | Locking hooks and tension lock; stays closed even in fire |
| Storing batteries in quantity, no charging | PRIOCAB-Li EI90 cabinet | 90-minute cabinet, smoke-tight, ventilation and cable entries as standard |
| Storing and charging batteries | PRIOLION Classic or Premium cabinet | Socket strips, ventilation, smoke detection, automatic shutdown—Premium is VDMA 24994 thermal-runaway tested |
| Pallets, battery packs, incident response | PRIOCOVER mobile enclosure | 90-minute pop-over enclosure—place it over a pallet, or over a battery that is already burning |
| Large volumes, disposal streams, logistics hubs | PRIOROOM walk-in room | Modular EI90 room, any length, with racking, ventilation and detection |
The range
All housings in non-combustible A2-s1,d0 material with decor surface. All systems suitable for connection to ventilation, detection or building-control systems where applicable.
Two-leaf cabinet for storing and charging Li-ion batteries. 90-minute protection in both directions (DIN EN 14470-1 / EN 1363-2), GS certified, interior temperature rise ≤100 K.
The cabinet tested against the worst case: internal thermal runaway per VDMA 24994. Batteries ignited inside must stay inside, with an external temperature rise of no more than 150 K.
Fire-resistant storage cabinets to DIN EN 1363-1 with EI90 rating and smoke-tight closure, in full-height (4 shelves) and half-height (2 shelves) versions.
Containers for defective or damaged batteries: non-combustible thermal lining, absorbing filler packs that enclose the battery completely, tight-closing lids that stay shut in fire.
Pop-over mobile fire enclosure, open at the bottom: place it over a euro-pallet of batteries by forklift or lifting eyes—including batteries that have already begun to burn.
Individually designed walk-in room built from 42 mm non-combustible modular panels: EI90 walls, F90/EI90 ceiling, smoke-tight T90-RS doors, unlimited length.

Penetrations into the battery room
Cable and pipe routes into a battery room cross the same compartment boundary. Firebreak Service Transits seal those penetrations and stay re-enterable when the cabling changes.
Tell us what batteries you store and charge, in what quantities and where. Photographs and floor plans welcome.
We size the containment, check ventilation, power and escape routes, and align with your insurer's requirements.
Factory-built systems delivered—cabinets ready to plug in, rooms installed and commissioned on site.
Documentation for your fire file and insurer, user instruction, and periodic inspection by agreement.
Technical qualificationFire performance, charging capacity, test standard and monitoring functions vary by model and option set. Observe national regulations and your insurer's requirements; Pyralta confirms the configured scope in the quotation.
