Heliox as the Eurpean market leader in fast charging solutions of electric buses is proud to have powered the all-electric bus fleet of 6 buses that operate in the Bus route 305 between the cities  Bettembourg and Dudelange in collaboration with Voyages Emile Weber and VDL, The all-electric bus fleet in the South of Luxembourg is the second fully electric bus fleet Heliox has powered in Luxembourg, which enhances the country’s goal to reduce emissions and strive towards a more sustainable public transport system. As said by Romain Kribs the Managing Partner of Voyages Emile Weber: “Today, we have reached our goal: the electrification of public transport.”

In this turnkey project Heliox exploits true Smart charging- one Heliox ultra-fast 350 kW charging system has been used with a full automatic DC switch that enables a significant reduction on overall infrastructure cost. Specifically, Heliox has applied both a pantograph system with using the Heliox ultra-fast 350kW charger and two 2x30 kW CCS plug systems with a cable, all located at the Bettembourg depot.

In depth, the Heliox’s fast charging system used for charging the electric fleet on Bus Route 305 utilizes a pantograph, a flexible hinged assembly that enables a swift charging process- 350kW of power to the bus during 2-4 minutes.  For true Smart charging, 350kW charger uses a full automatic DC switch that is connected to two masts and enables to charge 2 buses with one charger while automatically switching from the fully charged battery bus to the emptier battery bus.

In this project, Heliox has provided the roof-mounted pantograph interface that complies with all the CCS standards and enables a trustworthy and a reliable system for the customer.  Using the roof-mounted interface has enabled to deliver the best TCO for the customer and an extremely fast implementation time of 2,5 month that include receiving the order to delivering a fully operational charging system for an electric bus fleet. In addition, the roof-mounted pantograph system is compatible with any bus manufacturer that uses a pantograph system in its infrastructure to connect.

An additional two 2x30kW Heliox fast chargers have been provided, each connected to a charging pillar on one side and featuring a CCS plug on the other for overnight charging at the depot.

Heliox fast chargers are also capable of communicating and can connect with whichever OCCP 1.6 Backoffice system that is preferred by the customer, this type of flexibility ensures that the

customer can use the most suitable remote diagnostics and management system that maximize the value and insight to be caught from the chargers.

“The Netherlands now has 9 E­Mobility implementation projects, making it a proven transition partner for efficient zero emission public transport systems. In addition, our clean and efficient electric vehicles are in day-to-day operation in several German cities. With this experience, we are a good match for Luxembourg’s ambition to make public transport sustainable,” says Ard Romers, director of VDL Bus & Coach Nederland.

Koen van Haperen, Business Development at Heliox says: “This project shows that public transport companies can easily start to electrify their bus fleet. Reliable charging infrastructure is there to provide high availability. In less than 3 months we have executed this project from order to launch together with our partners. Zero Emission Public Transport is not just an idea, it is reality.”

Heliox is determined to unceasingly reassure the drive of sustainable mobility as a front runner and help cities like the city of Luxembourg in their journey towards low-carbon, sustainable future.
