For Mercedes-Benz, being dynamic is a mindset. To save energy, the eCitaro features acceleration control: whether empty or fully occupied, whether a solo bus or an articulated bus – the eCitaro always accelerates under full load with identical dynamics from the stop or the traffic light. This prevents unnecessary energy consumption and leads to a passenger-friendly driving style. Both bus models have an identical 2 x 125 kW drive. In addition to the drive, the battery equipment is also modularly designed. Lithium-ion batteries are used. In the case of the solo bus, two, four or six battery modules are used on the roof. They are supplemented throughout by four battery modules in the rear. Each of the modules consists of 15 cell modules and a control unit. The individual cell modules each accommodate twelve battery cells, and the total capacity of the batteries amounts to 243 kWh.
