Which charging infrastructure for heavy-duty battery electric vehicles?

Electric trucks can help largely to reduce CO2 emissions in the transport sector – but as they usually cover long distances their limited range is a problem that can only be solved by the deployment of a large charging infrastructure network across Europe. In this context a new Fraunhofer ISI study on behalf of the European Automobile Manufacturers' Association (ACEA) analyses possible charging locations for battery electric trucks on the continent. The study is based on data collected from 400,000 trucks and 750,000 stop locations in 35 European countries.

Realistic Test Cycle Assessment of PHEV

The potential of plug-in hybrid electric vehicles (PHEV) to reduce local pollutant and global greenhouse gas emissions strongly depends on their real-world usage and the share of kilometres driven on electricity, the so-called utility factor (UF). In the European CO2 fleet targets, generic functions for UF of PHEV are used derived from in standardized testing procedures, or test cycles, such as the Worldwide Harmonized Light-Duty Vehicles Test Procedure (WLTP). We find that the current WLTP UF parameters are too optimistic about real-world UF since long-distance driving was missing in earlier estimates, actual charging is less frequent than commonly assumed and real-world all-electric ranges are lower than WLTP ranges.

National Cycling Plan: How will Germany become a cycling nation by 2030?


On behalf of the German Federal Ministry of Transport and Digital Infrastructure (BMVI) and coordinated by ifok GmbH, Fraunhofer ISI and the PTV Group have played a key role in developing the National Cycling Plan 3.0. Approaches to further promote cycling in Germany and turn the country into a nation of cyclists by 2030 were developed in a dialogue forum and incorporated into the National Cycling Plan. The plan was presented to the National Cycling Congress (NRVK) by Andreas Scheuer, the Federal Minister of Transport.
