Graphene-based ultracapacitors give trucks a boost of acceleration

Adgero, the French transport tech developer, has unveil the world’s first operational energy-saving, hybrid electric system for road transport at Britain’s biggest commercial vehicle conference this week.

Adgero will display the regenerative braking-powered UltraBoost ST, a kinetic energy recovery system (KERS) installed on a curtainsider semi-trailer – that aims to cut fuel and carbon emissions by up to 25 per cent.

Adgero’s unique hybrid technology consists of an electrically driven axle mounted under the semi-trailer, powered by a bank of ultracapacitors, and controlled by intelligent management software that automatically controls regenerative braking and acceleration boost.

The UltraBoost ST uses a compact and lightweight YASA motor (the same axial flux motor as used in the Koenigsegg Regera) to recover kinetic energy, otherwise lost as heat during braking, and stores it in high-power graphene-based ultracapacitors from European manufacturer Skeleton Technologies – who helped develop the KERS technology for road haulage with Adgero last year.

Leading European manufacturer SDC Trailers installed the system on a 13.6m curtainsider trailer, finished in the livery of major UK-based transport and distribution company, Eddie Stobart. The transport operator will be conducting road testing of Adgero’sUltraBoost ST system in coming weeks.

President of Adgero SAS Mack Murray commented:

“The Adgero UltraBoost ST system has the potential to boost fuel efficiency, reduce overall fuel consumption and reduce associated emissions. And because our hybrid system can be easily and economically retrofitted to existing fleets, voluntary fleet-based implementation could have an immediate and meaningful impact on fleet costs and vehicle emissions within a very short timeframe.

“Road haulage accounts for over a fifth of the EU’s total CO2 emissions, so fuel efficient solutions are crucial. We are beginning to see regenerative braking systems in automotive applications but the market clearly needs a similar solution for articulated lorries.

“Unveiling the world’s first operational hybrid electric system for road transport at Britain’s biggest commercial vehicle show has taken a real collaboration between leading industry players and we’re now looking forward to the next phase of road testing in coming weeks.”

Head of Engineering at SDC, Jimmy Dorrian, said:

“Operator efficiency was the driving force behind the (KERS) trailer innovation. Our customers are always looking for ways to reduce their fuel consumption and overall carbon footprint, especially in demanding applications such as heavy terrain or continuous urban transport.”

Last week Adgero signed a €3.5 million distribution agreement to ensure the UltraBoost ST system for road haulage was powered by modules from Europe’s leading ultracapacitor manufacturer, Skeleton Technologies.

Combining such a distributed electric powertrain with a battery electric prime mover would provide not only range extension capability but also improve drive traction for both single and multi-trailer road trains.

Electric truck takes up delivery duties for BMW in Munich

100% electric trucks from the BMW Group and the SCHERM group will be in service from today in Munich. This means the BMW Group will be the first automobile manufacturer in Europe to use a 40-ton electric truck for material transport on public roads. It was launched at the BMW Group Plant in Munich by Bavaria’s Minister of Economic Affairs, Ilse Aigner.

The electric 40-ton truck – a model from the Dutch manufacturer Terberg – has successfully completed its first test drives. On 7 July, the car will go into regular operation and travel eight times a day between the SCHERM group logistics centre and the BMW Group plant in Munich. It will transport different vehicle components, such as shock absorbers, springs and steering systems.

The electric truck by the BMW Group and the SCHERM group will be exclusively charged with electricity from renewable sources. The combination of this and the alternative driveline means the 40-ton truck helps the environment while it is on the road – it’s CO2-free, quiet and generates almost no fine particle pollution. Compared to a diesel engine truck, the electric truck will save 11.8 tons of CO2 annually. This is equivalent to the distance a BMW 320d Efficient Dynamics would travel when going around the world almost three times.

The truck battery takes three to four hours to charge. When fully charged, the vehicle has a range of up to 100 kilometres. Thus, the electric truck can theoretically complete a full production day without any additional recharging.

Bavaria’s Minister for Economic Affairs, Ilse Aigner: “Bavaria is a leading industrial and research location. It is crucial that the Bavarian economy is also at the forefront in electric mobility. BMW is making an important contribution to this and is showing that you can succeed on the global market with sustainable products made by innovative companies.”

Hermann Bohrer, Head of the BMW Group Plant in Munich: “With our electric truck, we are sending another strong signal for sustainable urban mobility. We are contributing to reducing emissions in the city and are proud to be the first automotive manufacturer in Europe to use an electric truck of this size to transport materials on public roads.” Thus, the innovative truck is another valuable contribution to sustainable production.

Jürgen Maidl, Head of Logistics at BMW Group, emphasised the potential of the electric truck. “With this project we will gain valuable information on what will be possible with electric trucks in the future for city logistics. The BMW Group, along with our partner the SCHERM Group, is once again bravely embarking on a new journey and delivering pioneering work.”

Kurt J. F. Scherm, CEO of the SCHERM group underlined: “As a supplier of transport solutions, it is especially important to us to offer sustainable transport. The electric truck is the first step towards CO2-reduced transport logistics. In addition, this innovative truck is charged with 100% green energy.“

Urban mobility – and for the BMW Group this also includes urban logistics and transport — is a topic with great future potential. Since the end of 2013, the BMW i brand has been on the market. In addition, the company has launched its successful car-sharing programme DriveNow and established it in international cities. The BMW i3 vehicles are currently being introduced into the DriveNow fleets step by step.
