FEV presents developments for sustainable mobility at Aachen Colloquium
Global vehicle developer, FEV, presented its mobility solutions at the Aachen Colloquium Automobile and Engine Technology (ACK).
FEV offers a number of solutions in the area of alternative drive systems. In addition to battery electric drive systems, hydrogen technology also has a key role in the future. FEV presented a fuel cell developed in collaboration with ElringKlinger at the technical exhibition that can be used for multiple purposes, due to its high outputs and structure that was designed for mass production. The benefits of this drive system can be used in a 100% fuel cell vehicle, a battery hybrid system, or as a range extender.
The electric motors of electrified vehicles can only call up their maximum power for a short time during operation, as this creates a high thermal load. At the ACK, FEV presented a cooling solution that counteracts this limitation. While water cannot be used as a coolant for cooling directly at the copper windings in the electric motor due to its conductivity, FEV uses a special non-conductive oil which is also used as a lubricant in the e-motor.
Within the system, the centrifugal force in the motor operation leads the oil via the shaft to the heat-conducting copper windings to cool them efficiently. This allows the power density of the motor to be significantly increased and the increased torque to be called up for longer. Alternatively, cooling can be used to reduce the size of the engine while maintaining the same power density, thus saving installation space in the vehicle.
Another highlight for FEV at the ACK is a lighting concept. This innovative 3D technology developed in-house has already been successfully used in outdoor advertising also offers entirely new possibilities in the automotive sector. Whereas previous 3D processes for displays mostly relied on holography and autostereoscopy, this patented solution is based on light field technology. It can be used to produce high-quality 3D images that can be seen without the need for glasses or other aids.
In the vehicle cockpit of the future, this will allow holographic operation elements to be created, such as a three-dimensional controller or switch projected virtually from the centre console, which the driver can comfortably operate by hand and which is captured by sensors. This 3D light know-how has already been used to develop vehicle tail lights for prototypes, in which the rear light optically projects from the tail light of the vehicle and is thus detected much better and more quickly than with conventional systems. This remarkable technology increases traffic safety several times over.
FEV also informed ACK visitors of solutions in the field of autonomous driving. Validating these automated driving functions requires systems that recognise the various scenarios in road traffic during test drives, evaluates them, and prepares them for the developers. FEV is taking on this key challenge with a data management and assessment system developed in-house, which uses the computing power of the Microsoft Azure cloud platform. The results of the collaboration between FEV and Microsoft will be displayed at the stand.
FEV also displayed different concept vehicles on site - e.g. “SVEN”, a fully electric, compact three-seater designed as a car-sharing vehicle for sustainable, urban mobility. “SVEN” (shared vehicle electric native) celebratied its world premiere this year at the Geneva Motor Show. It also received positive responses recently from visitors at the IAA in Frankfurt.
