Solutions for Lithium-Ion-Batteries

Customized Fire Detection and Fire Protection Systems

Titelbild Lithium-Ionen-Batterie

Energy storage systems, production areas for electric vehicles, hybrid traction vehicles or parking areas with charging stations have something in common: Lithium-Ion-Batteries. This new technology brings new challenges which demand for innovative solutions.

The so-called thermal runaway is difficult to stop. Given that this exothermic chain reaction usually takes place at the battery cell level, the spread of the reaction to the battery system and subsequently to the device or vehicle must be prevented as quickly as possible. According to the current scientific state of knowledge, the early detection as well as the withdrawal of energy through cooling is the only way to interrupt the chain reaction.

Our holistic concepts for fire detection and high-pressure watermist systems offer not only that, but also many other advantages.

Advantages of our Solutions for Battery Fires

Firefighting with High-Pressure Watermist


Development of a fire with and without a HPWN-System


  • Significant reduction of temperatures in the fire zone
  • Local inerting and reduction of heat development
  • Minimal consumption of water
  • Limitation of the fire spread
  • Partial washing of fire gases
  • Minimal space requirement
  • Easy integration into existing structures
  • Lower investment and life-cycle costs

The right system guarantees early detection



  • Individual concept and design based on the fire scenario
  • Detection of initial fires as early as possible
  • Open to technology based on application (linear heat detectors, smoke aspiration systems, point detectors etc.)
  • Solid data base from 1:1 fire tests
  • Compatible interfaces and software (housing technology, fire departments, firefighting system)
  • Integration into the overall safety concept

Test and Climatic Chambers

Controlling the Worst-Case Scenario


With FOGTEC high-pressure watermist technology, critical test scenarios can be brought under control at any time. The excellent cooling effect and local inerting removes heat from reacting lithium batteries and reduces heat generation through flame suppression. The low-maintenance FOGTEC systems are ideal for continuous and repetitive operation, enabling higher test capacity!

Prüfstand NEC

Regardless of whether combustion or battery-powered, when entire vehicles or drive units are being inspected, safety and rapid intervention are of the highest priority. Should an incident occur, FOGTEC high-pressure watermist systems are ready for use again within a very short time. This means that interruptions to operations can be reduced to a minimum.

Parking Garages

And Charging Infrastructure


Especially in urban environments, parking spaces with a charging infrastructure are currently more important than ever and one of the basic prerequisites for functioning electro-mobility. High-pressure water mist systems are the best way to meet the new fire protection requirements, both for new projects and for retrofitting existing buildings.

Stationary Energy Storage Systems (ESS)

Fire Protection for ESS using Lithium-ion Batteries

Energy storage systems are systems that enable the intermediate storage of electrical energy for later use.

Based on the results of the SUVEREN (I+II) research project, full-scale fire tests for ESS were carried out. A white paper derived from the tests' results provides information and guidance for consultants, designers, manufacturers, operators of ESS, insurance and licensing bodies, and fire services.

Research Project SUVEREN2use (since the end of 2022)

suvern2use englisch


Within the SUVEREN2use research project, fire protection solutions are being developed for all areas of the lithium-ion battery value chain. These include cell and battery production, storage, integration into vehicles, use in stationary energy storage systems, recycling, remanufacturing for second-life applications and disposal. Furthermore, a battery-integrated extinguishing system is to be developed for use in large vehicles such as trucks, buses and trains as well as energy storage systems. The development of emergency concepts for batteries, electric vehicles and other large devices is another focus of the project.

Research Project SUVEREN (2017-2020)

As a consortium member in the research project SUVEREN, FOGTEC has taken on a leading role in research into fire protection for lithium-ion battery applications.
Extensive fire tests at cell and battery pack level have led to new fundamental findings. These findings are the direct basis for FOGTEC's fire protection concepts for applications with lithium-ion batteries and for further investigations as part of follow-up projects.
