Overhead truck on e-highway: ten percent less diesel-e-highway

Since the end of May 2019, the fleet of the Spedition Hans Adam Schanz from Ober-Ramstadt also belongs to a harmonious truck. Several times a day, the driver transports his cargo from the Odenwald to Frankfurt-East and also uses the overhead of the A5 test track – with first positive results. Scania supplied with the R 450 Hybrid the first overhead line truck, which is on the field trial section of the A5 at Frankfurt and uses this environmentally friendly and economical drive. First experiences are now available.

“After the first thousand kilometers that were evaluated, we were able to record a fuel economy at diesel of about ten percent. This is a pleasingly positive result after the first weeks of the test phase, “says Stefan Ziegert, product manager Sustainable transport solutions for Scania Germany Austria.

On the 7. May the first German electric motorway for freight traffic was put into operation. Between the motorway connection points Langen / Morfelden and Weiterstadt in South Hesse, overlay trucks can rely on electricity from the overhead line system. Frank Hagedorn, Regional Director Scania Mitte, supplied the hybrid truck to the management of the family business Schanz. Since then, the Spedition Hans Adam Schanz transports about 100 to 150 tonnes of freight from the seat of a color manufacturer in the front Odenwald to Frankfurt-East several times a day and passes the five-kilometer upper line pilot track on the A5 on the A5 on each tour. Frankfurt. This is the field test for testing the overhead electrical operation of heavy commercial vehicles under real conditions to the start.

Exclusive supplier of Oberlieiter-Feldschuch

The commercial vehicle manufacturer Scania is the exclusive supplier for this fund trial funded by the Federal Environment Ministry. In the coming months, four other hybrid trucks are delivered for the pilot project in Hesse. Frank Hagedorn is pleased that the company Hans Adam Schanz was selected as one of five Hessian freight forwarders to attend the project “electrified, innovative heavy traffic on highways” (ELISA). “Schanz is a very important customer for us. We have been working well and confidently with each other for many years.”

In any case, it looks at Hagedorn as a great luck that the test track was set up on the A5 “in front of the private door”. “We will look after the trucks in our workshop in Offenbach. The staff are enthusiastic that they receive an insight into such innovative future technology through Elisa.”

For this purpose, the Scania employees of experts of the Swedish corporate headquarters in Sodertalje were extensively trained in order to be able to optimally serve the diesel hybrid trucks with electricity customers if necessary. “The high-voltage technology requires the highest level of safety in dealing with the high tensions”, white Hagedorn.

Efficiency and environmental friendliness

For sustainable transport solutions at Scania Germany Austria, product manager Stefan Ziegert is responsible: “The actually charming in the art is that the vehicle can not only drive with the overhead line, but can also load the battery during operation,” he explains. This brings significant advantages, because in a commercial vehicle, which is often used around the clock, the service life for charging is reduced to a minimum. The electricity for the plant is 100 percent of renewable energies. “As a Swedish company, it is in particular in our DNA to connect the topics efficiency and environmental friendliness of vehicles. Because in the end, each of our customers buys such a vehicle not only from ecological awareness, but to earn money “, so braided.

The freight forwarders Christine Hemmel and Kerstin Seibert are enthusiastic that they were the first to receive a top-line vehicle from Scania. “We did not have to think for a long time when we were asked if we want to participate in the project,” says Christine Hemmel. On the one hand, the family Schanz the environment is very important. So all 38 Scania vehicles of Hans Adam Schanz fleet have been fulfilled for several years the exhaust standard Euro 6. On the other hand, in family business, it is always curious and interested to try something new. “The overhead control technology sounds very promising,” says Kerstin Seibert. “We are very excited about how she proven itself in practice.”

“When starting, the torque is immediately there”

At the wheel of El Leon, as this Scania R 450 Hybrid was baptized in Sweden, Thomas Schwieder sits. He is one of three drivers of the forwarding company Hans Adam Schanz, which are trained on the new overhead line truck. It is no coincidence that he drives the EL-Leon on the E-Highway at the maiden ride: He had advertised himself targeted by exactly this vehicle in the company. “I had read in the newspaper that the forwarding company will participate in the pilot project and immediately knew that I want to do that. Electromobility is an extremely interesting development – that’s the future – and I want to be there.”So the driving with an electrified truck for him is a premiere:” When starting, the torque is immediately there, you do not have to build it on the speed.”And then there’s the thing with the noise:” If you opened the window, you only hear the wheels of the wheels on the asphalt.”

An indication in the valve shows the driver if he drives in the field of test track on the right track. Because only then can the power collector, which have been developed by Siemens, can be extended and contacted. “There is no lot of scope to the right or left, because you have to keep track right,” says Thomas Schmieder. One thing of the habit, how the truck driver notes. Even the breaking track is no problem: “As soon as the turn signal is set, the pantograph drives automatically down and the overtaking process can begin,” says Schmieder.

Insurance: Innovative services for innovative drive concepts

Upper line, current collectors, batteries: As the hybrid trucks differ from a conventional diesel vehicle, the insurance of these vehicles is also faced with new challenges. In cooperation with the partner R + V / Kravag and Scania Insurance Development GmbH, a special concept was developed for the Scania hybrid vehicles intended for E-Highway test tracks in Germany.

While the use of the overhead lines are therefore not only accidents by mechanical but also by electronic action, for example, if the vehicle is damaged by electricity. Also damage to the electricity buyer of the truck takes over the comprehensive insurance. The R + V Group supports innovative ideas in heavy freight traffic. For the purposes of sustainability, the Wiesbadener insurance company also promotes electromobility through special services for E-vehicle owners. From the nationwide first field trial with overhead line truck in Hesse, the insurer promises exciting findings and therefore offers comprehensive insurance coverage for the participating trucks of Scania.

Overhead trucks also for other e-highway projects

For the planning and construction of the E-Highway test track in Hesse, the Federal Environment Ministry has invested around 15 million euros. Another about 15 million euros should flow into data collections and evaluations until 2022. “Thus, it is checked whether the overhead control technology is proven in practice operation and whether so climate and noise-friendly goods can be transported on the road,” explains Scania product manager Stefan Ziegert.

How much CO2 can actually be saved? How do the trucks behave in different weather conditions and conditions of use? What happens if several hybrid vehicles go under the upper line at the same time? How much electricity must be supplied so that they can not only drive, but can also load their battery? These questions will be clarified in the coming years on the A5 and on two other test tracks that arise in Schleswig-Holstein and Baden-Wurttemberg. On the A1 for Reinfeld is then tested if a connection to a port works. In Baden-Wurttemberg, the suitability for local passes is to be tested on the main road B 462 at Rastatt. Also for these routes Scania exclusively supplies five vehicles.

When the efficiency of the technology is determined in this experiment, trucks could in future be generally electrified in the future and then – so the vision – maybe even without the internal combustion engine. For this, everyone would have to be almost 15.000 motorway kilometers in Germany with overhead lines. For just under 70 percent of total freight traffic take place on the most important roadways, which focus on about 4000 highway kilometers. On the other hand, sections of around 15 kilometers would be sufficient on these routes to drive the next 50 kilometers of battery electric.

  1. Ekektromobility without reflection.
    The desire to drive electrically and thus “emission-free” is politically intended. Only when our energy generation is 100% renewable, then such a concept should be tracked real; How much do we have??

    Both the diesel engine as well as modern power plants only have an efficiency of about 40%. So it does not matter where the issue arises – in the power plant or on the highway in the diesel engine and all this for 10% relocation of emissions represented as saving???

    We should consider whether we want to open the Buchse of the Pandorra a second time; The first time it was the nuclear power without disposal concept!!

    Man claims to be smart!??!… then he should act like that … or????

    Klaus big, engineer ..

  2. I also find quite mischief. 10%.. If you alone the hardware costs that costs the whole thing … and then my opinion also consumes electricity without a car driving, or? Again pointless costs … ne, that is not the solution in my eyes. By the way, a lot of so-called O-buses drove in Berlin East Rum … there was schonmal.
