BESS system and signal protection

Battery storage systems combine sensitive, fieldbus-networked controls and high-voltage/ heavy-current components in a very small space. The systems are often exposed to external influences (lightning strikes) or are positioned close to other EM interference sources. Environmental and internal EM influences should be taken into account from the outset when planning the often CAN-based networking of components, in order to ensure interference-free communication and to protect components from damage.
