Lightning and surge protection concepts for charging infrastructure
Constant availability of electrical power is a decisive factor for the charging process. The fact that intelligent transformer stations, battery storage systems and charging stations are primarily erected outside means that they are especially susceptible to the effects of lightning discharge and the resulting surges which might exceed the dielectric strength of the electrical components many times over. Furthermore, voltage peaks in the power grid from, e.g. switching operations or earth faults and short-circuits, should be regarded as a possible threat. The consequences are defective electronic components and a charging post which is out of order. Should the surge occur during the charging process itself, it can even damage the actual vehicle (e.g. the charging controller or battery).
Mr. Tobias Kerschensteiner works as a Business Development Manager at the Business Unit Energy at DEHN+SÖHNE. There, he is responsible for the segments of Smart and Power Grid, LED-Street light Systems and charging infrastructure for electro mobility in combination with lightning and surge protection concepts, eahrting systems and safety equipment. He is employed at DEHN since 2007 and in several positions responsible for the energy branche.
