Kurzbeschreibung (Abstract)
Battery electric vehicles with a range of more than 500 km suitable for long distance driving require large battery capacities of more than 70 kWh. These high capacities have a high energy requirement in production phase and, due to their large mass, lead to a higher electrical energy consumption in the use phase. In contrast, dedicated hybrid drives show great potential in terms of minimizing the ecological impact. With focus on efficiency, driving, and shifting comfort at the same time, the dedicated hybrid powertrain DE-REX was developed and investigated at the IMS at TU Darmstadt. However, further potential has been identified with regards to reducing electrical energy and fuel consumption and increasing shifting comfort under high power demands. Therefore, the knowledge gained from the DE-REX powertrain will be applied to the new "Two-Drive-Transmission for Long Range (TDT4LR)" powertrain concept. The focus of this paper is on the TDT4LR with four gears for electric and hybrid operation, which is being presented for the first time. The technical highlights and advantages compared with the DE-REX are discussed regarding package, efficiency, and shift quality.
