By manufacturing power electronics for alternative drive technology, alternative power generation and self-sufficient storage solutions, we make a major contribution to climate protection. The electronics are installed in all electrically powered vehicles, solar systems and home storage systems. For the project "E-Mobility Cluster Regensburg" Prettl Electronics Automotive GmbH has developed together with other companies a modular charging system for DC/DC charging. The fast charging system is designed to shorten the charging stop for a range of 500km to 14 minutes. The setup of a test environment also comes from PRETTL Electronics Automotive GmbH.
