The energy transition is accompanied by new technologies and, at the same time, new acoustic challenges. The DEGA’s Noise Working Group has published three new factsheets on current issues relating to renewable energy. Two of these were written by our colleagues Niklas Löcherer and Thorsten Otto: they examine the noise emissions from battery storage systems and the charging infrastructure for electric vehicles.
The fact sheet on battery energy storage systems highlights the acoustic challenges associated with the expansion of large-scale battery storage systems. It focuses on noise generated by cooling systems, inverters and transformers, as well as ways to effectively reduce noise through early acoustic planning and appropriate mitigation measures.
The factsheet on charging infrastructure for electric vehicles explains what noises are generated during charging and why cooling the vehicle’s battery plays an important role: as charging and cooling capacity increases, so too can noise levels. It is therefore particularly important to take sound insulation into account at an early stage, especially for charging points located near residential areas.
Both factsheets bring together the latest findings, measurement data and practical recommendations for forward-looking planning. They thus make an important contribution to ensuring that the expansion of renewable energy and electric mobility is carried out in a way that is compatible with noise control requirements.
