Dr. said. Volker Wessing (Federal Minister for Digital and Transport) delivered his speech at “Daimler Bus Electronic Mobility Days” on Monday. According to the minister, the buses are helping to make Germany climate neutral. Sure, if 50 people got on the bus, one bus would replace 50 cars — according to Milkmaid’s calculation. It seems easy at first. But Wesing also sees a big problem: costs. That is why he wants to provide funding from the state and adds that openness to technology will be very important to him in the future. The state is providing 1.25 billion euros in funding by 2024 for the transition to e-buses.
You’ll be very happy to hear all this at Daimler Truck, because they are working hard on the new, climate-friendly generation of buses. Daimler Buses wants to offer CO2-free vehicles in every sector by 2030. Mercedes-Benz and Daimler Trucks are the only manufacturers still making city buses in Germany. So the star buses are “Made in Germany”. DaimlerTruck AG can be proud of that.
In 2021, 700 electric commercial vehicles were sold, and in 2022 this number should triple, that is, almost 2,100. Martin Daum, Chairman of the Board of Management of Daimler Truck AG, is optimistic about the future. He sees his group well-prepared for an electric future, but he also notes that an electric car will always be more expensive than a diesel one.
If the value of the combustion engine components of a commercial vehicle with a combustion engine is €25,000, then the cost of the electrical components of the same car is €100,000. The German Federal Government covers up to 80% of the additional costs generated. But Daum openly admitted that there is a political will to build all-electric cars in the future. Daimler Truck AG now wants to comply with this wish.
Daum sees Germany’s infrastructure as particularly important and that there is a lot of catching up to do. says in the direction of d. White Till Oberorder, head of Daimler Buses, also appealed to the Minister of Transport, noting that politicians were invited to deal with the infrastructure issue.
To prepare for the future, Daum and Oberwörder were able to introduce the new eCitaro Range Extender with a new fuel cell and new batteries this week. While the automotive division relies on electric vehicles only, a dual strategy is being pursued with buses: In addition to the purely electric strategy, the fuel cell strategy will play a central role in future buses, especially long-distance buses.
This means: In 2023, the Mercedes-Benz eCitaro will come with a range extender. The range extender is not a diesel engine, but a fuel cell. The fuel cell is supplied by Toyota. The Japanese have been familiar with hydrogen for many years and therefore have a lot of knowledge. The fuel cell is the “second generation Toyota fuel cell”. The “mini-station” has dimensions of 1270 x 630 x 410 mm and weighs 240 kg.
The range extender in the eCitaro is integrated with the NMC 3 battery. The eCitaro can cover nearly 300 kilometers without the range extender. Thanks to the small fuel cell, the range increases to 400 kilometers. The fuel cell and tanks are located on the roof of the bus.
With the single eCitaro Range Extender, six hydrogen and fuel cell tanks are located on the roof at the level of the driver’s cabin and front axle. Hydrogen is refueled in the normal way through a tank nozzle on the side of the bus. Refueling time is good 10 minutes. In the eCitaro Range Extender articulated bus, the tanks are in the same place, with only the fuel cell moved to the height of the joint. Here, too, refueling takes place in the normal way through the nozzle of a tank on the side of the bus.
Daimler Trucks has high hopes for fuel cell production in the future. On the other hand, Euro7 is likely to be very complex, so manufacturers will probably not think further in this direction.
Daimler Buses wants to deliver home-grown battery and hydrogen carbon-neutral models in every sector by 2030. Focus First
