The German government set ambitious targets to reduce CO2 emissions 65% by 2030 and 88% by 2040, thus increasing the pressure to find efficient and sustainable solutions for transportation and subsequently reliable charging infrastructure.
For this project a new approach was chosen, using masts that Power a total of 1MW.Three swivel masts and four charging masts have been installed at the charging depot at Betriebshof Friesdorf Godesberger Allee 120 in Bonn.
Moreover, seven FAST DC 150 liquid-cooled kW have been installed in a separate building, the E-Zentrale. A digital control system with a touch panel monitors the charging infrastructure, providing feedback on the status of the chargers, energy consumption, charging times, error messages, and load management, and is in contact with the energy supplier regarding available electrical power.
The depot parking space could be left intact as there is sufficient space to park two buses close to one another allowing the charging infrastructure to be installed without taking up additional space. The charging cable is attached to the charging reel which enables two e-buses to be charged simultaneously and the island between is kept clear for bus drivers walking between the buses. Moreover, the installation of the control room gives access to remote monitoring. All combined resulted in a flexible, intuitive, time and space-saving solution.
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.
