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.
