Mercedes-Benz B-Class E-CELL Plus Concept

Specification and walpaper car - Mercedes-Benz B-Class E-CELL Plus Concept » A new addition to Mercedes-Benz’s portfolio of electric cars is the near-series Mercedes-Benz B-Class E-CELL Plus Concept – a compact model that meets all the needs of daily motoring with a total range of up to 600 kilometres. 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 and a continuous output of 70 KW with a 50 kW 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.

When the battery possesses sufficient energy, the vehicle runs locally emission-free on electric power alone. The energy accumulator can be recharged by means of a conventional domestic power socket. Rapid charging is also possible with this vehicle. This enables a charging time in the order of one hour.

When the battery charge status drops below a certain limit, the combustion engine is activated (“Range Extender mode”). The large range which is available in “Range Extender mode” ensures that the vehicle will always reach its destination, even if the battery is flat. Acceleration from 0 to 100 km/h in approx. 11 seconds and the top speed of 150 km/h are both attainable in either operating mode. In order to ensure the most efficient possible motoring, two variants are possible, depending on the vehicle’s speed:

Below a speed of around 60 km/h, the combustion engine and generator attend to on-board power generation (“serial mode”). In this case, the combustion engine is run in the most fuel-efficient mode.

At speeds of over 60 km/h the combustion engine acts as a driving engine together with the electric motor (“parallel mode”), transmitting the generated power to the front axle. Any excess power generated by the combustion engine is used to charge the battery and to run the ancillary units.
