Mercedes-Benz presented its first electric vehicle with Range Extender at the 2011 Frankfurt International Motor Show in the guise of the Concept B-Class E-CELL PLUS. The combination of electric drive and petrol engine ensures excellent suitability for both everyday use and long journeys. The energy accumulator takes the form of a lithium-ion battery from Deutsche Accumotive, which enables local emission-free driving up to a range of 100 kilometres (62 miles). Thanks to the additional three-cylinder petrol engine, the Concept B-Class E-CELL PLUS has a total range of up to 600 km (373 miles). The Concept B-Class E-CELL PLUS adds an all-purpose battery-powered vehicle with Range Extender to Mercedes-Benz’s range of electric vehicles.
A new addition to Mercedes-Benz’s portfolio of electric cars is the near-series Concept B-Class E-CELL PLUS – a compact model that meets all the needs of daily motoring with a total range of up to 600 kilometres (373 miles). As such, this electric vehicle is also ideally suited to long journeys and offers its driver unrestricted mobility. This is made possible by the combination of a powerful electric drive generating a peak power output of 100 kW (136 hp) and a continuous output of 70 KW (95 hp) with a 50 kW (68 hp) petrol engine. The latter performs a dual role: at low vehicle speeds it charges the battery via a generator. At higher speeds – on prolonged motorway stretches, for example – it additionally serves as a driving engine, acting on the front wheels together with the electric motor via a newly developed automatic transmission.
In all-electric, local emission-free mode the Concept B-Class E-CELL PLUS has a range of up to 100 kilometres (62 miles). This covers over 80 percent of daily driving needs. The total range of up to 600 kilometres (373 miles) allows the vehicle to be used for long journeys, too. This means that the electric vehicle with Range Extender is fully suitable for everyday use and can be relied upon to reach its destination, even with a fully discharged battery. In combined driving mode the vehicle emits 32 grams of CO2 per kilometre.
“The Concept B-Class E-CELL PLUS shows that our new range of compact cars is all set for the future. The variant involving a battery-electric vehicle with Range Extender further broadens the range of alternative drive concepts from Mercedes-Benz,” notes Prof Dr Thomas Weber, Member of the Board of Management at Daimler AG, responsible for Group Research and Mercedes-Benz Cars Development. “This innovative and highly flexible concept meets our customers’ wish for emission-free driving coupled with a large range.”
The Concept B-Class E-CELL PLUS is an electric vehicle meeting all daily motoring needs which combines the best of two worlds: all-electric driving and driving with a tried and tested high-tech combustion engine. This combination allows long journeys which to date have been the reserve of vehicles powered by a combustion engine alone or electric cars fitted with a fuel cell. The two drive units are extremely compact and are accommodated in the engine compartment at the front together with the transmission and the generator. The powerful lithium-ion battery and the fuel tank are located in a false floor at the rear – the so-called “Energy Space” – which has been developed specially for alternative drives. For other drive variants it is also possible to install gas or hydrogen tanks here, for example.
