En studie av vilka brandtekniska krav som bör ställas på energilager innehållandes litiumjonbatterier
Sammanfattning: One of the most common batteries used for energy storage systems is the lithium-ion battery due to its high energy and power density as well as long service life. Despite this, research is falling behind in relation to how stationary energy storage systems should be regulated when it comes to fire protection requirements. The risks of placing a large amount of Li-ion batteries in one and the same place are relatively unknown and is therefore an area that requires attention and further analysis. This report aims to identify and analyse the risks that may arise when an energy storage system with Li-ion batteries is installed inside a building. Furthermore, the purpose is to interpret and reflect upon different experts’ views on these risks and the solutions to limit them. The aim of the report is to stipulate possible fire-technical requirements for future energy storage systems in various buildings. The chosen methods were a literature study and an interview study, from which the results then were used to perform a risk evaluation. The findings of the report included, among others, that a stationary energy storage system with Li-ion batteries should be placed in a separate fire compartment provided with emergency ventilation. Legislation should also regulate where an energy storage system may be placed within a building, as well as its design.
