Termed the E-Cell Plus, the compact model from Mercedes made on B-Class platform is a range extender version of the EV that meets all the needs of daily motoring with a total range of up to 600 kilometers. As such, this electric vehicle is also ideally suited for long journeys and offers its driver unrestricted mobility.
The operating parameters of this plug-in hybrid system are binary in nature. When the battery has sufficient charge, the E-CELL PLUS runs on pure electricity. When it reaches a certain level of depletion, the range-extender engine kicks in to provide motive force and sends any excess power to drive a generator that can help recharge the battery.
Conditions permitting, the gas engine will be decoupled from the drive function at speeds below 37 mph. Further beyond this pace, the engine works in parallel mode with the motor both to provide drive and generate electricity.
Mercedes says the Concept B-Class E-CELL PLUS can run 0-62 mph in about 11 seconds and hit 93 mph using either of its power sources. The car’s advanced battery pack, which is produced by Deutsche Accumotive GmbH & Co. KG, a joint venture of Daimler and Evonik, nestles beside the fuel tank in a dedicated “Energy Space” beneath the rear cargo area.
It can store enough energy to let the E-CELL PLUS travel about 62 miles on a single charge while the range-extender engine can stretch that interval to almost 375 miles before its time for a plug-in recharge and/or pump-in fill-up.
