Bella novità di ZF che si inserisce nel mercato delle elettriche per cercare di aumentare l'autonomia a parità di pack-batteria. To increase the performance rating of the new electric axle drive system, ZF leveraged its expertise in systems to develop a new electric motor with a maximum power rating of 140 kW paired with a two-stage shift element. Vehicles with the new 2-speed drive consume less energy, which in turn extends range by up to five percent when compared to a one-speed unit. Shifts take place at 70 km/h. By connecting to the vehicle’s CAN communication it is also possible—if the customer so wishes—to devise other shift strategies, possibly linked to digital map material and GPS. For example, the vehicle could identify from the GPS route programming how far it is to the next charging station, enabling it to respond predictively by switching into Eco-mode. More effective shifts would also be possible in accounting for topography on the interstate, and on inter-city journeys. The software in the drive can also be updated via the network link to Cloud services via over-the-air updates. For vehicle manufacturers, the new 2-speed drive offers two options for using improved energy conversion efficiency. The Original Equipment Manufacturer (OEM) could either go for an extended range while retaining the same size of battery, or utilize a smaller batter. The 2-speed concept also offers benefits for OEMs pursuing performance. Until now, with electric motors, vehicle manufacturers have had to choose between high initial torque and a high top speed. We are now resolving this conflict and the new drive will be compatible for performance and heavier vehicles—for example for passenger cars towing a trailer. —Bert Hellwig ZF’s modular approach combines the 2-speed gearbox with even more powerful electric motors rated for up to 250 kW. This delivers enhanced acceleration and, potentially, faster top speeds. With its modular concept, the new drive can meet a variety of requirements. Via GreenCarCongress
Cari utenti, sono uno studente dell'Università di Pisa. Sto costruendo un sondaggio per la valutazione dell'auto elettrica e la propensione all'acquisto. Inoltro il link con il questionario relativo, la cui compilazione richiede al massimo dieci minuti del vostro tempo. https://goo.gl/forms/iBtw12aCSc5FgpY13 Il questionario è anonimo e i dati utili solamente a scopi accademici. Vi ringrazio in anticipo per la disponibilità. Lorenzo
