The Road to Emission-free Driving by Daimler – Part 3 of 5

posted by NSL

Electromobility today.
Zero emissions, full emotions. Electric vehicles from Daimler are not only particularly clean and quiet, but also offer maximum driving pleasure.

 

 

A calculation that makes sense.

Our electric vehicles have lower levels of fuel consumption and noise pollution than conventionally powered vehicles, offer the same amount of safety and spaciousness – and provide no end of driving pleasure. Thanks to the electric motor maximum torque is available right from the start, allowing powerful acceleration. These features are shared by all current and future electric vehicles from Daimler, such as the smart fortwo electric drive, Mercedes-Benz A-Class E-CELL, Vito E-CELL, SLS AMG E-CELL, B-Class F-CELL, Citaro FuelCELL HYBRID, and Fuso Canter E-CELL.


A locally emission-free, agile city car.

It has everything on board that makes a smart a smart – except a combustion engine. Rather, the smart fortwo electric drive is powered by a 30 kW (41 hp) electric motor: economically, quietly, and locally emission-free. With an acceleration from 0 to 60 km / h in 6.5 seconds, this agile city car is hard to beat at traffic lights. Its highly efficient lithium-ion battery is well protected in the sandwich underfloor unit between the axles. The two-seater can be recharged either from a domestic power socket or at a public charging station. A single battery charge is sufficient for a range of 135 kilometers, which is ideal for city traffic. Large-scale produc- tion of the smart fortwo electric drive is due to commence in 2012. Pure electric driving pleasure on just two wheels is promised by the smart prototypes escooter and ebike. The smart escooter offers safety systems that are unique for this category of vehicle, such as ABS, airbag, and Blind Spot Assist, and its 4 kW (5.4 hp) electric motor provides it with a range of up to 100 kilometers. With the ebike, the cyclist is assisted by an electric motor up to a speed of 25 km / h. These smart two-wheelers, introduced in late 2010, perfectly round off the range of vehicles for emission- free urban mobility.

 

Daimler’s generous offer of electric vehicles ranges from city cars and bikes to vans and the super sportscar (right). Ideally suited for locally zero-emission city mobility are the smart fortwo electric drive and the prototypes smart escooter and ebike (left).
 Five seats and full flexibility in the interior make the Mercedes-Benz A-Class E-CELL the ideal electric family car. The absolute superlative among electric vehicles in terms of performance, drive technology, and design is the SLS AMG E-CELL (right).


The first family car for city driving.

The A-Class E-CELL is the first series-produced battery-powered electric car from Mercedes-Benz. This family-friendly five-seater, which is entirely suitable for everyday use, offers a spacious, versatile interior and trunk – with no compromise in spacious- ness and variability, since the two highly efficient lithium-ion batteries are safely and conveniently located in the underfloor unit. They make for a range of over 200 kilometers (NEDC figure). A quiet, locally emission-free electric motor provides a peak power of no less than 70 kW (95 hp) and a generous torque of 290 Nm. With an acceleration from 0 to 60 km / h in 5.5 seconds and an electronically limited top speed of 150 km / h, the electric A-Class is designed to meet the requirements of urban mobility. Production of a total of 500 units of the A-Class E-CELL began in Rastatt in late 2010.

 

The Gullwing electrified.

An electric car for both country roads and the racetrack was created by Mercedes-AMG in the summer of 2010 in the form of the SLS AMG E-CELL concept car. This vehicle is powered by four synchronous electric motors located near the wheels, with a combined peak output of 392 kW (533 hp) and a maximum torque of 880 Nm. Acceleration from 0 to 100 km / h in 4.0 seconds and a high-voltage lithium-ion battery with a capacity of 48 kWh are further outstanding figures of this Gullwing model. The fascinating super sportscar with locally emission-free electric drive will be available in the showrooms as of 2013.

 

A van with “green charging.”

With the first battery-electric truck available ex-factory from an automotive manufacturer, Mercedes-Benz is opening up a new chapter in drive technology for light commercial vehicles. Its zero-emission drive and its maximum payload of 900 kg make the Mercedes-Benz Vito E-CELL ideal for use in inner-city zones and environmentally sensitive areas. The lithium-ion batteries of the Vito E-CELL are located in the underfloor unit and thus do not restrict load space. They have a combined capacity of 36 kWh, which is sufficient for a range of around 130 kilometers. The Vito E-CELL thus meets the average customer requirements for a range of 50 to 80 kilometers per day, plus a generous reserve. Its electric motor has an output of 60 kW (82 hp), with 280 Nm of torque and a top speed of 80 km/h that is highly suitable for this type of vehicle. The dynamic performance of the Vito E-CELL is therefore in keeping with the accustomed high level of modern diesel engines. Following its successful start in the major cities of Berlin and Stuttgart, this electrically powered van has been in active service in Spain’s Basque country since early 2011.

 

The silent light-duty truck.

The near-series Fuso Canter E-CELL study vehicle shows how emission-free mobility can be realized in the next-highest weight class. The purely electrically powered light-duty truck is based on a Canter with a gross vehicle weight of 3.5 tonnes. Its 40 kWh lithium-ion batteries housed in the chassis frame allow a range of 120 kilometers. The 70 kW (95 hp) electric motor, positioned between the batteries and the driven twin-tired rear axle, has a maximum torque of 300 Nm and accelerates the electric truck to its limited top speed of 80 km/h. The Canter E-CELL is the next step after the successful Fuso Canter Eco Hybrid with parallel hybrid drive, of which more than 1,100 units have been sold.

 

An initial batch of 100 Mercedes-Benz Vito E-CELL vans, the first in the world to be equipped with electric drive ex-factory, were delivered to customers by the end of 2010; a further 2,000 units are planned for 2011 (left). The Fuso Canter E-CELL with the latest-generation fuel cell drive celebrated its world premiere in 2010 at the IAA Commercial Vehicles (right).
Emission-free, quiet as a whisper, and easy on natural resources: The Mercedes-Benz Citaro FuelCELL Hybrid (left). The Mercedes-Benz B-Class F-CELL (right) makes for emission-free driving with a range of up to 400 kilometers and accommodates up to five people.


The future of local transportation.

The latest fuel cell technology is also used in the Mercedes-Benz Citaro FuelCELL Hybrid city bus. The hybrid system with fuel cell, electric motor, and lithium-ion batteries is characterized by outstanding environmental compatibility: This bus emits no pollutants during operation and is almost silent, so it is ideal for use in highly burdened inner-city areas and in mega-cities. On the roof are seven cylinders containing 35 kg of hydrogen in all. The water-cooled lithium-ion batteries have a capacity of 27 kWh, which is sufficient to power the electric motors at a constant 120 kW (163 hp). The Mercedes-Benz Citaro FuelCELL Hybrid makes for permanently zero-emission local public transport and thus constitutes a key element of mobility for the future.

 

The first fuel cell automobile in series production.

Manufacture of a small series of the Mercedes-Benz B-Class F-CELL commenced in late 2009. With its 700-bar hydrogen tank in the sandwich floor unit, the first fuel cell passenger car from Mercedes-Benz to be produced under series conditions attains an operating range of around 400 kilometers. Its electric motor develops an output of 100 kilowatts, with a torque of 290 newton- meters, and thus has the power rating of a two-liter gasoline engine. The clean, quiet, and powerful fuel cell drive unit consumes 3.3 liters per 100 kilometers (diesel equivalent) and makes for a top speed of 170 km / h. The next step toward market introduction has already been taken: In December 2010, Mercedes-Benz delivered the first of a total of 200 B-Class F-CELL cars in Germany and the United States. In California alone, 70 B-Class vehicles with fuel cell will be handed over to customers by 2012.
