Properly protected –­­ Safe charging Protection concepts for the charging infrastructure of electric mobility www.dehn-international.com The electric mobility megatrend The number of registered electric vehicles is growing substantially as more and more people recognise the benefits of environmentally friendly mobility. Through the connection of charging infrastructure with power grids, electric mobility is forming an important basis for the energy revolution. Given this background, it is not surprising that the expansion and further development of electric mobility are concerns for the future. However, the handling of electricity entails some danger. Dangers posed by thunderstorms If lightning strikes in close proximity, damage to buildings and infrastructure can occur. Not only direct lightning strikes but also those close by and even remote can cause fires or surge damage to electrical devices and systems. Switching operations in transformer stations or even the switching of electrical energy on a charging post can generate switching surges, which can also involve negative effects. Just a low amount of energy is often enough to cause damage. Damage during the charging process Since charging installations are predominantly set up outdoors, a serious danger is posed to them by the effects of lightning discharges. The surges resulting from this exceed the dielectric strength of the installed electronic components inside the charging posts many times over. Mains-related...
