Siemens's research department is feverishly laboring on the subject of electric mobility which could be a major part of its eco-centered portfolio with an investment of 19 billion Euros contributing a measly 25 percent of overall income. The increasing demands on the EV and the design for a power network play a very important part.
Subjects currently on the table are energy production and distribution, traffic and energy management, smart metering, power electronics, software and sensor technology and, more importantly, drivetrain systems, and also the recovery and storage of energy.
Within the research range, Siemens has developed an integrated system composed of a motor/generator, power electronics and an interface with a battery connection for vehicles powered by electricity. Alois Ruf is the main influence behind the basic concepts that brought RUF Automobile GmbH to design an electrically powered car.
The vision of the head of the carmaker based on the Bavarian town of Pfaffenhausen is a simple energy transfer system which resulted in his hydroelectric power plants feeding 35 million kW hours of electricity annually into the electric network of Germany and can also be used to power the eRUF.
The interdependence of Siemens, the electric industry leader, with RUF, the automobile industry leader, will power the best possible cooperation for the electric mobility of the future.
Siemens has developed a modified powertrain for the eRUF Greenster.That's the reason why an initial variant of the concept for the ground-breaking eDrive from Siemens will be showcased in the Geneva Motor Show. Although the car to be shown in the Geneva event will still come with a central motor with a power yield of 270kW and 950Nm torque, the succeeding model will be created as a small series with RUF as dual-motor concept equipped with the ground-breaking integral eDrive.
The eRUF will therefore be the first electric vehicle equipped with a two-directional network connection which is capable of recharging in under an hour at a 400V power outlet. The same outlet can, when required, feed energy back into the network. If all goes well, this innovative concept will become operational by next year.
