Off-Grid on Holiday - What can Emission-Free E-Trailers do?

The smarter E Podcast Episode 44 | April 01, 2021 | Language: German

More and more electric cars are driving on German roads and gradually the expansion of the charging infrastructure is also making progress. But other interesting developments are also supporting the shift towards a more sustainable energy world. One hot topic, for example, is so-called e-trailers, electric trailers for the transport sector. But what do these solutions actually look like? Where are there currently still hurdles and a need for clarification? And when can we expect the first e-trailers on the market?
