EVmore Ultimate Efficiency Driveline Concept
摘要
ZF is a leading company for electric drivelines. Advanced driveline technologies are being developed as a knowledge base for future electric drives. ZF has built a demo-vehicle to demonstrate a highly efficient driveline concept in an electric all-wheel drive architecture. The ultimate efficiency front axle has a highly efficient gearbox layout in combination with an efficient electric motor. The rear axle in combination with eConnect, an ultra-efficient, switchable second drive, delivers power on demand and is disconnected during standard driving situations to avoid drag losses. Both e-motors avoid heavy rare earth elements for sustainability reasons. A benchmark vehicle was rebuilt with ZF-advanced technology and is released to drive on public roads. It has shown a range extension by 7%, which can be measured by energy consumption compared with the original benchmark vehicle.
