Electric Drives offer considerable potential for saving fuel and reducing emissions, especially in urban traffic. In order to ensure the successful use of these systems in future generations of vehicles, they must be functionally designed and optimally configured.

Portfolio

  • Design and development of compact electric drives with high torque and power density
  • Hardware and software development for control units, e.g. for optimum efficiency drive control and vehicle control
  • Development of new manufacturing processes for electric drives, e.g. cast coils
  • Construction and testing of prototypes and functional samples, e.g. wheel hub drives
  • Basic design/Preselection of hybrid components
  • Development of structural proposals and operating strategies
  • Simulation under consideration of driving cycles and distance profiles
  • Creation of special simulation tools based on MATLAB/SIMULINK
  • Execution of installation investigations and development of integration proposals
  • Design of periphery and cooling system incl. highly integrated thermal management of the battery system
  • Mechanical and electrical integration of energy storage systems into existing vehicles
  • Reliability evaluations of the electric drive train
  • Performance of function tests
  • Business and economic impact assessment
  • Development of Electro Mobility strategies for companies
  • Development of charging infrastructures
