The public transport operator Verkehrsgesellschaft Ludwigslust-Parchim (VLP) is responsible for school transport and intercity transport in the rural district area. 12 bus depots are to be equipped with charging infrastructure that takes into account the special requirements for vehicle scheduling.
Heliox has installed 23 Flex power units with a total of 68 charging points at 12 locations; the power units distribute the electricity dynamically to the charging points. In this way, longer downtimes at night and during the lunch break, can be used optimally for charging. In addition, dynamic charging supports the purchasing strategy and the use of electricity from renewable sources.
The charging points were installed free-standing in the outdoor area or on the rear wall of carports; a balancer is also used as a cable routing system in the carport. The project is rounded off with a 12-year maintenance contract and the implementation of monitoring and load management via Chargesight.
With 45 battery-electric buses, VLP has electrified around 22% of its bus fleet. The buses are charged on site using electricity generated from renewable sources, resulting in emissionfree bus operations and a significant reduction in air pollutants and noise emissions.
Heliox and TU/e aim to develop an integrated solution that makes charging heavy electric vehicles accessible without negative consequences for local electricity networks. Together, we want to achieve this by developing and demonstrating a new, multiple and dynamic charging system for heavy electric vehicles that is equipped with software-controlled stabilization to absorb disturbances on the local energy grid.
The intended system will consist of a dynamically configurable charging system based on modules that can be connected in parallel, each with three 60 kW outputs. With this they want to be able to distribute the loading capacity dynamically over several vehicles. The charging system can therefore be used for opportunity charging up to 360 kW for a single vehicle as well as for regular charging of several vehicles.
In addition, smart software and a microcontroller board are being developed. The converter of the charging system can be used via this software to compensate for grid disturbances. The disturbances are neutralized via a low impedance path. This allows losses on the grid to be converted into usable energy, while improving the voltage quality of the grid. In fact, the system completely takes over the function of current power filters on the basis of smart control.
