Product information „BUNCKER® transport and storage containers Pro Line Heavy M“

Lithium batteries are used in a wide range of applications and are becoming increasingly popular due to their high energy density and long service life. It is, however, important to know that lithium batteries, when used properly, are generally safe but still carry some risks, including the danger of thermal runaway.

Given the potential hazards posed by lithium batteries, safe and certified packaging for transport, storage, and handling is essential. BUNCKER® has developed a patented packaging solution to mitigate risks and provide protection in the event of thermal runaway or other incidents. The patented fire-resistant, insulating, and filtering material, known as “Altilium,” and the mechanisms for controlled containment and venting of gases aim to suppress thermal runaway, which can occur with lithium batteries. Since BUNCKER® can protect both non-critical and critical lithium batteries, these systems provide a versatile solution.

Specifically, the transport of critical lithium-ion batteries remains a major challenge. The storage and transport container was developed for the safe transport of critically defective lithium-ion cells. Unlike comparable metal boxes in Packaging Group I, no filler material is required here. This makes this container the ideal solution for internal storage and transport in all battery states. The container has been tested and meets the ADR/Packaging Instruction LP 906 requirements. Please contact us with any questions.

Size and capacity of the battery transport container - Authorized for lithium-ion batteries up to 90 kWh.

The transport container has overall external dimensions of approx. 1500 x 1200 x 1250 mm (LxWxH). Inside the box, the dimensions are 1220 x 880 x 850 mm (LxWxH), which corresponds to a content of about 910 liters. It also has an approval according to Packaging Group I as a large packaging made of steel (LP). The sturdy base frame is four-way forklittable. The empty weight of the transport container is approx. 508 kg. The maximum permissible payload is approx. 700 kg. This corresponds to a permissible gross weight of 1208 kg. It is permissible to transport lithium-ion batteries up to 90 kWh in size M. Please contact us for the approval if the container is used for this purpose: info@lion-care.com or +49 7151 256 4811.

Application of the BUNCKER® Pro Line Heavy M Transport and Storage Container

To load the container, first open the side panels and release the latches. Then the lid can be lifted with a forklift. The batteries can then be placed on the base plate for loading. The plate features an insulating non-conductive mat. The batteries themselves can be secured with tension straps. The lid can then be placed back on, the clamps closed, and the side panels closed. Please refer to the instruction video in the Downloads tab.

The container can also be stacked during storage to maximize space efficiency.

Contents of the UN certification

The UN certification is an important aspect of BUNCKER®, as it shows that the packaging meets the safety standards for the transport of dangerous goods set by the United Nations. This certification ensures that the product has passed a fire, leak, and drop test as well as a worst-case scenario assessment to ensure that it effectively contains and prevents the hazards associated with lithium batteries. Tests and assessments show that BUNCKER® can contain a thermal runaway.

If defective or damaged batteries need to be packed, UN approval based solely on drop and stack tests is not sufficient. For shipping in accordance with P911/LP906, additional certification is required to confirm that the packaging meets the following parameters:

  • Withstand a worst-case scenario fire test
  • No leakage occurs
  • The container has a well-functioning gas management system
  • High heat resistance must be provided

These criteria must be observed based on the maximum tested kWh of the lithium-ion batteries mentioned.

Always request the transportation approvals for P911/LP906 that confirm the approved type of packaging instruction, how to secure the batteries against shifting, how to make the box fireproof, and the consumption limits in kg and kWh for road (ADR), rail (RID), and sea transport (IMDG).

A copy of these certificates should accompany the packaging during transport.

A safe system thanks to the patented insulation material Altilium®

The BUNCKER® Pro Line HEAVY is fully equipped with our patented Fibercon Altilium® CP Blanket (FACB). This innovative product has the potential to filter toxic HF gases. In addition, the FACB is non-flammable, fire-resistant, and insulating.

BUNCKER® an environmentally friendly solution with convincing advantages

BUNCKER® packaging is known for its environmentally friendly and sustainable properties as well as its long service life, low total cost of ownership, and robustness

Environmentally Friendly and Sustainable

In the development of BUNCKER® packaging, particular emphasis was placed on environmental friendliness. They are made from environmentally friendly materials that minimize environmental impact. In addition, BUNCKER® packaging is often designed to be easily recyclable, reducing waste and promoting a circular economy.

Long service life

BUNCKER® packaging is designed for a long service life. They are developed and manufactured with durable materials to ensure they withstand the rigors of transport, handling, and storage. Through their long life, BUNCKER® packaging helps to reduce the frequency of replacements and waste.

Low total cost of ownership

BUNCKER® packaging provides cost advantages over their entire life cycle. While the initial investment may be higher than less durable alternatives, the longevity of BUNCKER® packaging means they need to be replaced less often. BUNCKER® can be serviced by one person, and no inner packaging is required. This reduces the overall costs associated with packaging procurement, storage, transport, handling, waste management, and cleaning.

Robustness

BUNCKER® packaging is designed to be robust and resistant to damage. They are designed to protect the contents effectively during transport and storage and to reduce the risk of product damage or spoilage. The robustness of BUNCKER® packaging contributes to its long service life and general cost savings.

Low environmental impact

In a fire, it is important to prioritize human safety and property. While water is often used as a extinguishing agent due to its availability and effectiveness, this is an alternative firefighting method that can minimize environmental impact.

Transport notes

All legal regulations, as well as any markings and labels, must be observed during transport. All handling and transport procedures for the container must be carried out with appropriate and safe means. Before transport, ensure that the lid is securely closed to the base frame.

Repair and disposal

Damaged transport containers must not be reused. Repairs must be carried out exclusively by manufacturer-authorized specialists or by the manufacturer itself. Contaminated components must be disposed of properly according to their contamination.

Certification and guidelines

Lithium batteries fall into danger goods class 9. Therefore, numerous guidelines must be followed when transporting lithium batteries. The transport box is specifically designed for the strictest safety regulations.

Certified for Packaging Group I

The Pro Line Heavy container meets the requirements of Packaging Group I, meaning substances with high hazard potential may be transported in it. To achieve this classification, the boxes must pass drop tests from a height of 1.8 m. All packages with the code “X” may be used for Packaging Groups I (II and III).

Meets ADR / Packaging Instruction LP 906 guidelines

All lithium-ion cells or batteries and lithium metal cells or batteries that have been damaged and no longer conform to the applicable regulations according to their manual must conform to the provisions of this special provision. This applies, for example, to cells that have leaked or vented, have suffered external or mechanical damage, or have been identified as defective for safety reasons, or could not be diagnosed prior to transport. If it is found that lithium-ion cells or batteries under normal transport conditions could tend to rapid disassembly, dangerous reactions, flame formation, dangerous heat development, or dangerous emission of toxic, corrosive, or flammable gases or fumes, these defective cells must be transported according to packaging instruction P 911 or LP 906. These packaging guidelines then require Packaging Group I.

Additionally, there are further testing requirements: during a possible incident of the lithium-ion battery, the surface of the shipping item must never exceed 100°C. Only short-term temperature spikes up to 200°C are permissible. No flames may form outside the shipping item, and no splinters may escape from the shipping item. Furthermore, the structure of the shipping item must always be maintained, and a gas management system must ensure internal pressure relief. Compliance with the test requirements must be demonstrated by real-fire tests

If you want to use the container for the transport case “critically defective” under LP 906, please contact us to obtain the corresponding certification for this transport case: info@lion-care.com or +49 7151 256 4811.
