In Germany, they are testing the first 100% electric European trolleybus in real conditions

The chair “Production engineering of electric mobility components(PEM) from RWTH Aachen University has tested what it claims to be in real conditions the first European prototype of a fully electric truck with an overhead current collector.

The vehicle was used on the five-kilometre-long Siemens “eHighway” near Berlin.

In addition to PEM, the Machine Tool Laboratory (WZL) at RWTH Aachen University and the Japanese car manufacturer Isuzu are also involved in the “LiVe” research project, funded by the German Federal Ministry for the Environment. .

The combination of battery and pantograph of a purely electric powered utility vehicle works. Valuable discoveries will now turn into further development.

Over the past few months, the Kampker team had already carried out several test drives in Aachen and simulated the so-called pantograph bracing at the stationary catenary. On the Groß Dölln test track, the truck came into contact with the catenary for the first time during the race in July and received power for propulsion via the pantograph.

The prototype of the projectReducing Life Cycle Costs in Electrical Distribution Transmission(LiVe) premiered last December.

The research projectLIVEPLUSdedicated to “Life cycle cost reduction in electrical distribution transport by means of modular pantograph-based systems for trucks and tractor heads”, should also benefit from current measurement data. In this project, the RWTH PEM chair also electrifies tractors for heavy transport via the overhead line.

In addition, in the next production vehicles of the “LiVe” project, experience with fuel cells will be gained to come closer to the goal of a modular powertrain.
