Automated Design and Optimization of Transmissions for Electric Vehicles
- 6 Downloads
At present, the costs of electric vehicles are still comparatively high, which is partly due to expensive battery systems. With an efficient automated development process from the Institute for Automotive Engineering at RWTH Aachen University, the transmissions of electric vehicles can be designed according to demand, so that costs can be saved in the overall vehicle system, for example by using smaller batteries.
Innovative Development Method
Large quantities of electric drives and thus a relevant reduction in CO2 fleet emissions can only be achieved if they offer the end customer a similar performance to the conventional drives known to them, and at comparable costs. The large physically justified disadvantage of heavy and cost-intensive battery storage systems can partially be compensated by a requirement- oriented design of the drive train.
