  • Do energy storage containers need independent lightning protection

    Do energy storage containers need independent lightning protection

    Therefore the need for optimized and reliable electrical protection against the influence of lightning and surge events becomes mandatory. A risk assessment per IEC 62305-2 should first be performed to understand better if an external lightning protection system (LPS) is. Energy storage containers housing lithium-ion batteries or other advanced chemistries require specialized lightning protection due to their dual vulnerability: According to 2023 data from the Lightning Protection Institute, unprotected industrial facilities face 47% higher equipment failure rates. Here, one T2 DC SPD is required to protect against inductive coupling caused by an S1 event (a direct strike on the LPS). However, if a metal structure is used, the effect of inductive coupling is lessened so a DC SPD is not necessary. A Battery Energy Storage System (BESS) contains AC/DC. As a specialist in lightning and surge protection, we also see ourselves as having a special responsibility in this area and create customised, reliable protection concepts for the holistic protection of battery storage systems. Energy Storage Systems (ESS) are now a mature technology.
