Does Denmark have a standard for lithium-ion battery fire and explosion testing?

Denmark also lacks specific protocols for Lithium-ion battery fire and explosion testing, e.g., UL 9540A, which is a benchmark test recommended in many other countries. Danish guidelines may furthermore provide more clarification on when and which suppression systems should be installed, depending on BESS design parameters.

Are lithium-ion batteries a viable option for energy storage and balancing grids?

Aside from presenting a viable opportunity for energy storage or balancing electrical grids, BESS present significant fire and explosion risks, due to employment of Lithium-ion batteries (LIB), which are susceptible to thermal runaway (TR).

How should lithium-ion batteries be stored?

Under the DK1 guideline, facilities storing Lithium-ion batteries must ensure direct access from public roads and maintain unobstructed fire routes, including access roads and clear areas for emergency vehicle maneuvers. It is imperative that these routes remain free from obstructions, such as snow and ice.

What is the separation distance of end-of-life batteries?

When the end-of-life batteries are stored in quarantine areas, or in the case of BESS with capacities larger than 2000 kWh, then this separation distance increases to 10 m. The separation distances mentioned in DK2 are dependent on the capacity of the batteries, SOC, and type of storage (in a container or not).
