OverviewThe SiS Li‑Ion Premium I/O 90 battery cabinet by LaCont is a tested solution for safe storage and optional charging of lithium‑ion batteries. Designed and tested to VDMA 24994 standards, the cabinet limits risks from internal thermal runaway and provides >90 minutes external fire resistance. With an assessed total energy capacity up to 8.0 kWh, integrated pressure relief and mechanical ventilation, it reduces the release of flames, projectiles and shrapnel in battery failure scenarios.
Main features- Designed for storage and charging of lithium‑ion batteries; tested according to VDMA 24994
- Tested for internal thermal runaway and >90 minutes external fire resistance
- Proven to prevent escape of flames, projectiles and shrapnel in real-world tests
- Maximum tested energy capacity per cabinet: 8.0 kWh
- Non-combustible construction; body RAL aluminium colour, doors RAL 1023 (traffic yellow)
- Perimeter fire-protection seals that foam up automatically in case of fire
- Double-leaf door with central mullion; lockable with profile cylinder; audible reminder 60 s after doors left open
- Technical mechanical ventilation to avoid internal heat build-up; ventilation shuts off on fire detection
- Base with 100 mm clearance for vehicle underpass; removable base panel
- Height-adjustable powder-coated steel shelves: 4 levels, 75 kg load per level
- Floor tray AwSV-compliant, powder-coated sheet steel, capacity 5 litres
- Optional power-strip version: up to 3 shelf levels with power strip (10 earthed sockets per strip)
- Integrated control unit with visual and audible status indicators and fire detection as standard
- Complete emergency disconnection of cabinet power supply; surge protection included
- Operating voltage: 400 V (3-phase)
Control & safety systems- Control unit with visual status indicator (normal / fault / alarm) as standard
- Built-in sensitive smoke detector and fire detection; immediate visual and audible alarm on detection
- Automatic shutdown of cabinet power supply and mechanical ventilation when fire is detected
- Potential-free contact for alarm differentiation and forwarding to a control centre
- Cable preparation inside and outside for retrofit connection to a building fire alarm system
- Optional GSM module for remote monitoring and alarm notification
Active fire suppression (optional)Optionally fitted with an integrated aerosol fire‑extinguishing generator that activates automatically upon critical temperature rise or fire; the aerosol fills the interior within seconds to suppress flames and limit fire spread.
Protection objectives- Protect stored goods from external fire
- Limit spread of smoke and fire if an internal battery fire occurs
- Minimise risk to personnel from toxic or explosive gas release
- Protect against projectiles and shrapnel
- Signal critical internal conditions to staff and emergency services and interface with existing fire-protection systems
