DE-REX Powertrain

The layout of the DE-REX powertrain bases on the coaxial arrangement of two subtransmissions (STM) with two gears each.

One permanent magnet synchronous motor is connected to each two speed subtransmission. Additionally, an ICE is coupled to one subtransmission resulting in a parallel-series hybrid architecture.

The parameters of the DE-REX powertrain (like the power of the drives and the gear ratios) were determined by applying a multi-objective optimization method developed at the IMS.
