ZETT - Zero Emission Terminal Tractor

System Solution for Battery-Powered Internal Transport

The German sea and inland ports represent a central interface for the national and international transport of goods and are therefore indispensable for the entire German economy. The container transport within a port or terminal is mainly carried out by diesel-powered tractors, so-called terminal tractors (TT). In the context of the current efforts to reduce CO2-, pollutant- and noise-emissions, a few concepts of electrified TT have already been presented. However, the significantly higher acquisition costs compared to diesel-powered TT prevent economic operation and thus the widespread use of electrified TT.

Therefore, a system solution for battery-powered internal transport, that meets both ecological and economical requirements, is developed within the project ZETT. In this context, the Institute for Automotive Engineering is investigating how the design of the powertrain and the charging infrastructure can be realized by coupling fleet and longitudinal dynamics simulations. The aim here is to enable operation without restrictions and at the same time to prevent over-dimensioning of the powertrain components - especially the battery. At the end of the project, the gained knowledge will be transferred into the construction of a prototype vehicle, which will be used to demonstrate the suitability of the concept. For this purpose, the prototype will be used on the container terminals of the associated partners in real operation.
