Wittenberg, 30 May 2023 – At this year’s smarter E Europe trade fair in Munich, TESVOLT has joined with DENIOS to present an all-in-one solution that combines a battery storage system and fire protection – the only one of its kind in the world. The POWER SAFE product line also meets the most stringent safety requirements in commercial and industrial settings, for example in operations located in water conservation areas or regions that are at a risk of forest fires, or as required by some insurers. Products in this line feature cases offering F90 fire resistance rating and are available in various sizes, from small-scale 80-kWh solutions to large energy storage systems with several megawatt hours.
Sophisticated fire protection case for extreme requirements
“For years now we have been engaged with the safe storage and handling of hazardous materials. TESVOLT not only has high-performance, durable storage systems, it also has some of the safest battery storage technologies on the market. However, in some cases, safety requirements are particularly strict, for example in countries with special environmental regulations or specific requirements from insurers,” explains Markus Boberg, Business Development Manager at DENIOS. “Now we have joined together to develop a technical solution that can meet the strictest safety requirements, by enclosing the battery storage system within an additional fire safety case.”
Proof of safety for public authorities
In the POWER SAFE product line, storage systems come in a spatial system with dual-frame construction classified as REI 90 or REI 120 fire protection. It can withstand fire, either internal or external, for at least 90 minutes, fulfilling the standards for safety certification demanded by approval authorities and greatly reducing complex approval processes. This safety certification also allows the system to be installed without a minimum clearance between it and adjacent buildings. Moreover, DENIOS offers round-the-clock remote monitoring and will alert the operator immediately in the event of a problem with the system. An aerosol-based extinguishing system is also available for the spatial system.
“TESVOLT storage systems already fulfil particularly stringent safety requirements. We have a multi-level safety concept and our storage systems are certified by the testing institute TÜV Rheinland. I am particularly pleased that we can now also offer our commercial customers a technical solution for highly sensitive environments. With this we have cleared yet another hurdle on the path to universal availability of clean energy,” says Simon Schandert, CTO and Co-Founder of TESVOLT.
The exceptionally high safety levels of TESVOLT storage systems are driven partly by the design of the battery cells: prismatic cells are considered to be the safest lithium-ion cells. At the system level, TESVOLT’s battery management system also monitors the voltage of each individual cell. This means the whole system is subject to constant plausibility monitoring. If the normalised range is exceeded, the system automatically switches to a safe state.
POWER SAFE spatial systems with fire protection come with European Technical Assessment (ETA) and associated CE labelling. This offers enhanced planning and legal security for country-specific approval processes.
