Daimler Buses to supply CO2-neutral automobiles in each section by 2030; eCitaro with Toyota fuel-cell vary extender


Daimler Buses goals to supply regionally CO2-neutral automobiles based mostly on batteries and hydrogen in each section by 2030. The preliminary focus shall be on the core markets of Europe and Latin America.

By 2039, solely regionally CO2-neutral new automobiles are to be bought within the core market of Europe. Within the metropolis bus section, that is to be the case in Europe as early as 2030.

To attain our local weather objectives, we’d like extra zero-emission automobiles. We actively assist public transport corporations to decarbonize their fleets and supply them with the corresponding infrastructure. We’ve got earmarked a complete of 1.25 billion Euro for this objective. Our objective: by 2030, each second metropolis bus must be electrified.

—Volker Wissing, Germany’s Federal Minster for Digital and Transport

Along with increasing its portfolio of CO2-neutral automobiles, Daimler Buses may even develop its service choices as a normal contractor for patrons’ full electrical infrastructure.

Daimler Buses plans to launch the primary all-electric inter-city bus from 2025 and coaches with hydrogen-based gas cell drive from the top of this decade. In keeping with the dual-track technique of its father or mother firm Daimler Truck, Daimler Buses is specializing in each battery-electric and hydrogen-based applied sciences—the one approach to supply tailor-made zero-emission options for the various wants of its prospects, the corporate says.

We wish to supply regionally CO2-neutral powertrains for every of our segments in our most necessary markets by 2030 and subsequently make a transparent dedication: from 2030 on the newest, we’ll solely supply CO2-neutral new automobiles within the metropolis bus section in Europe and won’t spend money on Euro VII know-how. We’re focusing our growth efforts fully on the zero-emission and totally electrically powered eCitaro.

We take a holistic view of electrification and go far past the automobile itself. We provide our prospects with electrical mobility on a turnkey foundation, which suggests they get from us all of the modules they want for a functioning electrical bus service: We provide the buses, we plan the mandatory infrastructure in addition to the charging administration, we handle the conversion of the depot and we prepare the employees. Our objective is for electromobility to change into an on a regular basis actuality within the bus enterprise.

Beginning in 2023, Daimler Buses may even equip its beforehand purely battery-electric Mercedes-Benz eCitaro metropolis bus, which has been in collection manufacturing since 2018, with a hydrogen-based gas cell as a variety extender in each solo and articulated fashions.

Daimler Buses is thus including a automobile with a variety of as much as 400 kilometers (solo bus) to its all-electric product portfolio within the metropolis bus section. As a variety extender variant, the highly effective and regionally CO2-neutral low-floor bus covers even demanding routes and practically 100% of all transport operators vary necessities.

Toyota is supplying the fuel-cell module. The TFCM2-F-60 is a second-generation flat-type module that produces 60kW energy and could be simply built-in into the roof of the bus, alongside the battery and hydrogen tanks. The mix of the battery and the gas cell as a variety extender eliminates the necessity for intermediate charging on-the-go.

TME engineers will assist the general design of the system and the mixing of the module into the bus to make sure optimum effectivity, energy and repair life. The heavy-duty unit’s effectivity ends in a relatively low consumption of hydrogen relative to the facility era. With an built-in voltage converter, the TFCM operates in a voltage vary of 450 to 700 volts and most effectively at round 30kW.



The Mercedes-Benz eCitaro G Vary Extender will characteristic an NMC 3 battery (98 kWh per pack), gas cell vary extender, hydrogen tanks, 2 x electrical hub motor, 2 x 125 kW, 2 x 485 N·m. The gas cell module is a second-generation unit from Toyota.

The eCitaro Vary Extender continues to be clearly designed to be used as a metropolis bus. The drive system continues to be based mostly on the very highly effective battery, whereas the gas cell serves purely to increase the vary and never as the primary power supply. The automobile is thus an all-electric hybrid bus that mixes each energy sources. The hydrogen is utilized in gaseous type at a stress of 350 bar.

As well as, Daimler Buses will supply the eCitaro with a brand new era of high-performance batteries from the top of 2022. The high-energy lithium-ion batteries enhance the capability per battery cell by round 50% for a similar weight and allow dependable ranges of round 280 kilometers (solo bus). The batteries shall be utilized in each the eCitaro, the eCitaro Vary Extender and the lately launched all-electric chassis eO500U from Brazil.

The eCitaro is a profitable mannequin from Daimler Buses—greater than 600 eCitaro are actually in day by day use by European prospects. In 2021, nearly each second all-electric metropolis bus newly bought in Germany got here from Daimler Buses.

Daimler Buses presents its prospects an entire system for the all-electric eCitaro, which incorporates undertaking planning and consulting providers for the graceful operation of an electrical fleet in addition to the whole development of the facility provide infrastructure. This additionally contains the corresponding development measures, that are provided on a turnkey foundation if required. On request, transport corporations can thus get hold of a coordinated general package deal comprising bus, energy and charging infrastructure in addition to appropriate software program, digital providers, applicable coaching for workers and aftersales from a single supply.

Specifically, the charging administration of battery-electric buses is essential for clean on a regular basis operations for patrons. Right here, with the lately introduced strategic partnership with IVU Site visitors Applied sciences AG, Daimler Buses has supplemented its portfolio with fleet management software program particularly tailor-made to the eCitaro with regard to charging administration.

Electrical chassis for Latin America. Daimler Buses is driving electrification ahead worldwide: manufacturing of the primary purely battery-electric bus chassis from Daimler Buses for Latin America and markets within the Oceania area, which has been specifically tailored to native necessities, will begin this 12 months. The eO500U chassis with a variety of round 250 kilometers shall be manufactured on the São Bernardo do Campo web site in Brazil and is essentially based mostly on the know-how of the eCitaro.

Daimler Buses has already taken 100 orders for the chassis in its principal Latin American market of Brazil. Supply is scheduled for between the top of 2022 and the start of 2023.
