Ten battery-operated heavy goods vehicles now transport containers between ships and the yard at the highly automated handling facility in the Port of Hamburg. The aim is to charge the batteries of these container transporters when the grid has a surplus of renewable energy generated in northern Germany. In addition to practical considerations, the project focuses on the model’s commercial viability.
The first battery-powered heavy goods vehicles in the world went into use at the HHLA Container Terminal Altenwerder (CTA) back in 2011. Now, a project is bringing together businesses and research institutions that are keen to find out how the batteries for these automated guided vehicles (AGVs) can be charged using surplus green power generated in northern Germany. To this end, a battery administration system is being developed as part of the BESIC research project (Battery Electric Heavy Goods Transports within the Intelligent Container Terminal Operation). The system calculates the ideal charging times – in both ecological and economic terms – by exchanging data with Vattenfall’s load forecasting system and the CTA terminal management system.
