Reference vehicle:
A-class 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 cooling incl. the battery (with ensured
life enhancement) and gained energy from harvesting architectures

November 2017 / Steiner OPTEMUS 22
• According to simulation results and testbench measurements
Objectives 2 and 3 will be achieved, objective 1 seems possible
with energy harvesting technologies and interior technologies
• Measurements in the demonstrator vehicle need to confirm these
results
• Objective 4 has already been confirmed by measurements in an
Eco-Driving/Eco-Routing demonstrator vehicle
• Measures for Objectives 5, 6 have been defined, work is in
progress
