In the largest vehicle project in the Hamburg electromobility model region, 235 battery-powered vehicles of varying sizes were tested for technical suitability in everyday operation.

The vehicles’ drive trains were converted to Karabag GmbH specifications, with technical optimisations and experiences from previous deployments being directly incorporated into the production process. It was important here to constantly monitor adherence to quality standards and firmly agreed delivery dates and, where necessary, to make readjustments. The consortium succeeded in achieving largescale system optimisation in the conversion process (combined with significant cost reduction), which made it possible in the case of many of the vehicles subsidised in the project to supply them at monthly costs of under € 300.

The consortium also succeeded in recruiting German industrial and SME businesses as business partners. The electric motors, for instance, will in future be supplied by Linde Material Handling GmbH, the battery management system comes from I+ME ACTIA GmbH of Braunschweig, while locally based suppliers, such as Hamburg-based metal processors Graupe-Thews GmbH, will in future also be involved in the conversion process. A sales strategy, including downstream organisational processes, was also developed and a maintenance infrastructure built up at Karabag GmbH. The vehicles were delivered out to users in several tranches over the period of the project.
