Product information „ENVAION VIO 10 Pro Transport and Storage Box “

Brief overview

The ENVAION VIO 10 Pro transport and storage box is a specially developed large-capacity container made from robust HDPE plastic for the storage, handling and transport of critically defective or damaged lithium-ion batteries. The P911-certified transport box is designed for batteries with a maximum energy capacity of 9 kWh and is particularly suitable for industrial applications, workshops, dangerous goods logistics, and recycling and disposal processes.

With base dimensions of 1,200 × 800 mm, the VIO 10 Pro complies with Euro-pallet dimensions and can therefore be integrated into existing storage and logistics processes. The box is stackable up to three high and designed for handling by forklift. A key feature is the integrated protection system comprising multi-part fabric inlays with AkkuGrain® filling material and a fire-retardant cover. This combination helps to limit the effects of a thermal event within the packaging.

AkkuGrain® filling material

The AkkuGrain® filling material is a granular safety material that releases water vapour when temperatures rise sufficiently during a battery event. This process absorbs heat, which can slow the spread of heat. At the same time, the water vapour can locally displace oxygen and reduce its availability. In this way, AkkuGrain® can help reduce the risk of reignition, mitigate explosive effects and reduce the release of hazardous gases.
In addition, the fabric inserts filled with AkkuGrain® allow batteries to be easily placed into and removed from the box. As the AkkuGrain® is securely contained within the inserts and the batteries are not covered with loose filling material, handling remains clean and convenient.

Technical properties of AkkuGrain®:

  • Physical state: Solid granules
  • Particle size: 2–5 mm ± 1.5 mm
  • Bulk density: 0.25–0.4 kg/l
  • Melting point: 1,400 °C
  • Aqueous eluate: 100 g/l at 20 °C
  • pH value: approx. 6
  • Conductivity: 18,000–19,000 µS/cm


Areas of application

The ENVAION VIO 10 Pro is designed for the storage, internal handling and transport of critically defective or damaged lithium-ion batteries. Thanks to its standard Euro-pallet dimensions, stackability and suitability for forklift handling, this bulk container can be integrated into existing commercial warehousing and logistics processes.

Typical areas of application include:

  • Industrial and manufacturing facilities
  • Battery manufacturers and battery service providers
  • Automotive industry and garages
  • Warehousing and logistics companies
  • Take-back and reverse logistics
  • Recycling and waste disposal companies
  • Temporary storage of critically defective lithium-ion batteries
  • Transport of critically defective batteries as dangerous goods

For transport, the batteries are positioned on the lower inlay and secured to prevent movement. The upper inlays and the fire-resistant cover are then inserted, and the lid is secured using the designated fastenings. Any remaining voids must be filled with suitable padding or filler material as required.

Approvals / Standards

The VIO 10 Pro is approved for the transport of critically defective lithium-ion batteries in accordance with Packing Instruction P911. The following approvals and markings are listed in the manufacturer’s documentation provided:

  • Packing Instruction P911
  • UN packaging marking: UN 4H2/X427/S/**/GB/7652
  • US DOT Special Permit: DOT-SP-21619

The ENVAION VIO 10 Pro container is therefore specifically designed for transport operations where critically defective lithium-ion batteries, cells or modules must be packed in accordance with the requirements of P911. Before each consignment, the specific condition of the battery, the applicable dangerous goods regulations and, where relevant, country-specific requirements must be checked.

Instructions for use

The boxes should be stored at temperatures between 5 and 50 °C in a well-ventilated indoor area. Direct sunlight, heat sources, flammable materials, as well as rain, hail and extreme weather conditions must be avoided. A maximum of three boxes may be stacked on top of one another.

For safe and convenient handling of the box, we recommend the use of suitable lifting equipment or a forklift. During transport, the container must remain closed and all fastenings must be securely locked. This ensures reliable handling and secure transport.

Conclusion

The ENVAION VIO 10 Pro combines a robust HDPE large-capacity container in Euro-pallet dimensions with a multi-part protection system comprising AkkuGrain®-filled inlays and a fire-retardant cover. Compliance with P911, the UN packaging marking and the design, which is suitable for batteries up to 9 kWh, enable the storage and transport of critically defective lithium-ion batteries in accordance with the applicable transport conditions.
