As one of the cities aiming at Zero Emission Urban Bus Systems (ZeEUS), Finland aimed to evaluate fully electric urban bus solutions, initially with 12 busses. Interoperability and Scalability were also elements of Helsinki’s requirement, albeit at an early stage.
The public transport company of the Finnish capital Helsinki operates 12 busses that have a total length of 12 meters. Reliable charging is ensured by a Heliox infrastructure project totaling 3MW. Heliox also worked towards their goal of standardization of fast charging using the inverted pantograph technology.
With Heliox providing modular, scalable products supported by 24x7 maintenance, care and a solutions-orientation.
The Helsinki City Transport (HKL) lent out the e-busses to 5-6 different operators who operated them alongside conventional diesel busses in different lines.HKL owned the charging infrastructure thereby doing their own part in the risk involved when introducing new technology. Roadblocks towards hesitancy in adoption of electric solutions are being worked on by the Finnish capital, and in potentially ‘global’ interoperability across brands and chargers by Heliox as part of long term product goals.
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.
