Concept
Reference vehicle:
▪ Fiat 500 E-Vehicle
Definition of „extreme conditions“ using 2 use cases:
▪ Use case 1: Hot ambient (35 °C, 40 % r.H.)
▪ Use case 2: Cold ambient (-10 °C, 95 % r.H.)
Impact of OPTEMUS:
▪ Use case 1: 60 % reduced energy consumption for passenger comfort and
33 % reduced energy for component cooling incl. the battery (with ensured
life enhancement) and gained energy from harvesting architectures
▪ Use case 2: 78 % reduced energy consumption for passenger comfort and
33 % reduced energy for component heating (and/or cooling) incl. the battery
(with ensured life enhancement) and gained energy from harvesting
architectures

Impact on Driving Range
Validation of OPTEMUS technologies:
→ calculation of overall benefit through Virtual Prototyping
November 2016 OPTEMUS 25
Estimated Impact on Driving Range
• 14 % (20 km) higher driving range at „normal“ ambient conditions (solely reduction
of traction energy through Eco-Driving, Eco-Routing – without Energy Harvesting)
• 38 % (44 km) higher driving range for Use Case 1 (hot ambient conditions)
• 70 % (63 km) higher driving range for Use Case 2 (cold ambient conditions)
