OPTEMUS in a Nutshell
Reference vehicle:
▪ A-class vehicle Fiat500e
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.)
Expected 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
