Mercedes-Benz pursues a comprehensive approach in powertrain electrification, and develops the EQ brand with a family of vehicles and an all-encompassing ecosystem, which, in addition to the vehicle itself, also comprises a comprehensive range of products related to electric mobility. This extends from intelligent services and energy storage units for private and commercial customers to charging technologies and sustainable recycling. On the road to emission-free driving, Daimler is systematically pursuing a three-pronged powertrain strategy to be able to realize maximum environmental compatibility across all vehicle classes (incl. commercial vehicles, vans) – with an intelligent mix of state-of-the-art internal combustion engines and partial electrification through 48-volt technology, tailormade EQ Power plug-in hybrids and electric vehicles with battery or fuel cell powertrains.
Stuttgart/Frankfurt. At this year’s IAA International Motor Show in Frankfurt, Mercedes-Benz is presenting pre production models of the new Mercedes-Benz GLC F-CELL as the next milestone on the road to emission-free driving. Under the technology designation EQ Power, the latest electric model (destined for subsequent series production) is set to combine innovative fuel-cell and battery
technology in the form of a plug-in hybrid: in addition to hydrogen, the allelectric variant of the popular SUV will also run on electricity. Intelligent interplay between battery and fuel cell, along with short refueling times, will in future make the GLC F-CELL a vehicle of high everyday practicality and also suitable for long-distance motoring. With 4.4 kg of hydrogen on board, the preproduction model produces enough energy for a range of up to 437* km in the NEDC. F-CELL drivers will also benefit from a range of up to 49 km in the NEDC thanks to the large lithium-ion battery. An output of 147 kW guarantees both dynamic performance and locally zero emissions driving pleasure. In unveiling the preproduction vehicles of the Mercedes-Benz GLC F-CELL, Daimler is taking another important step as part of its systematic “CASE” strategy.
Ola Källenius, Member of the Board of Management of Daimler AG, responsible for Group Research & Mercedes-Benz Cars Development, emphasizes: “Our many years of experience with fuel-cell technology pay dividends in the new GLC FCELL: its long electric range, short refueling times and everyday practicality of an SUV will make it the perfect vehicle. This is made possible by the compact construction of our fuel-cell system. Another genuine world first is the combination with a large additional lithium-ion battery, which can be conveniently charged using plug-in technology.”
The vehicles unveiled at the IAA represent a world first in which a fuel-cell-operated electric car uses a lithium-ion battery as an additional energy source that can be externally charged by means of plug-in technology. Through intelligent interplay, the two energy sources drive the electric motor while offering locally zero emissions driving pleasure. The long range, short refueling time, an output of 197 hp and the latest generation of assistance systems with powertrain-specific features demonstrate, based on the models on show, that the GLC F-CELL will be a familyfriendly electric vehicle of high everyday practicality. For this world first, the Mercedes-Benz engineers cooperated closely with partners from the Daimler competence network to develop a completely new fuel-cell system. Compared with the B-Class F-CELL, which has been on the market since 2010, the overall drive system offers around 40 percent more output. The fuel-cell system is around 30 percent more compact than before, can for the first time be housed entirely in the engine compartment and is installed on the usual mounting points like a conventional engine. Also, the use of platinum in the fuel cell has been reduced by 90 percent. This conserves resources while lowering the system costs – with no compromises in terms of performance. The lithium-ion battery in the preproduction vehicles on show has a gross capacity of 13.8 kWh and additionally serves as an energy source for the electric motor. For the first time, it can also be charged externally using plug-in technology. An
intelligent operating strategy in combination with the fuel-cell/battery system offers maximum efficiency and comfort. Just like the drive motor, the powerful storage battery is space-savingly installed in the rear of the SUV. By means of the 7.2 kW on-board chargers, it can be conveniently charged from a standard household power socket, a wallbox or a public charging station. The charging time is around 1.5 hours if the full capacity is used. Two carbon-fiber-encased tanks built into the vehicle floor hold around 4.4 kg of hydrogen. Thanks to globally standardized 700 bar tank technology, the supply of Daimler Communications, 70546 Stuttgart, Germany Mercedes-Benz – A Daimler Brand hydrogen can be replenished within just three minutes, which is about the same amount of time it takes to refuel a car with an internal combustion engine. The F-CELL vehicles on show at the IAA are powered by an asynchronous machine with an output of 197 hp and a torque of 258 lb-ft. As the electric drive requires no propeller shaft, this makes room for one of the two hydrogen tanks, while the second tank is installed under the rear seat bench.
