Exercise Lecture • Location: CNH E 46 • Time: Every Friday 12:15 to 13:30
Mode of Exercises • no standard calculation tasks • rather vaguely described tasks • many unknowns • assumptions necessary • several solutions possible • similar to “real” engineering work • work in teams → distribute work Ø One exercise lasts ~2-3 weeks Ø Every week we check your progress via a milestone Ø After 2-3 weeks: each group presents own solution in a 5 min presentation
Deliverables • Visit www.polybox.ethz.ch • Create new folder • Name it «VPS_TeamXX», where XX is your team number (01, 02, 03,…) • Share with your team- mates and with «anritter»
Polybox • System integration apps available for Mac OS, iOS, Windows, etc. • 50 GB of storage available • Your Data stays within ETH Zürich • Upload links for externals without registration
Deliverables • Upload your notes and calculations for every milestone until Friday 8am. • We will read and check until exercise lecture at 12:15pm. • After a presentation, upload your slides • If you decide to work within your folder, create subfolders «ExerciseX/Deliverables», where X is the exercise number.

Goal of Exercise • Develop understanding about the possible energy conversion chains involved in individual mobility • Investigate the CO2 footprint of various powertrain technologies • Establish fair basis to trade-off benefits against drawbacks
Exercise #1 Calculate and compare the best/worst-case CO2 emissions of a compact vehicle driving the New European Driving Cycle with the following types of propulsion systems: • Internal combustion engine, • Battery and electric motor.
Exercise #1 • Define possible in- vehicle and upstream conversion processes • Calculate energy- specific CO2 for the cases where fossil fuel is involved
