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

Key Results of the Project
Workshop “Solutions to electromobility challenges”, 18th October 2019, San Sebastian (Spain) 8
Key Results
Compact Refrigeration Unit (CRU):
✓ Core part of the heat pump system
✓ Enables energy efficient heating and
cooling of the…
− passenger cabin
− battery
− power electronics
✓ Manufactured prototype was tested and
evaluated on bench and in the
demonstrator vehicle
Workshop “Solutions to electromobility challenges”, 18th October 2019, San Sebastian (Spain) 9
Key Results
Battery as Thermal Storage:
✓ Significant higher thermal capacity due
to integration of phase change material
(PCM)
✓ Enables the storage of 0,9 kWh of
sensible heat (between 40 and 15 °C)
and 1,0 kWh of latent heat, which can
be used by the heat pump system
✓ Prevents the battery from overheating
during fast charging
Workshop “Solutions to electromobility challenges”, 18th October 2019, San Sebastian (Spain) 10
Key Results
Preconditioning Functionality:
✓ Ensures best comfort for passengers as
well as maximum driving range due to
preconditioning of the cabin and battery
✓ Uses user information as departure time
and desired cabin temperature as well as
cloud information (e.g. expected weather
conditions)
✓ Can be used via a smartphone app
Workshop “Solutions to electromobility challenges”, 18th October 2019, San Sebastian (Spain) 11
Key Results
Thermal Management ECU (TMECU):
✓ Optimal thermal management strategy
developed based on a control-oriented model
and mathematical optimization
✓ Reduced energy consumption for the cold
use case in the range of 7-11 % depending
on the operation mode
✓ Onboard control architecture realized with a
dSpace MicroAutoBox
Workshop “Solutions to electromobility challenges”, 18th October 2019, San Sebastian (Spain) 12
Key Results
Smart Seat:
✓ Peltier elements in the back and
cushion part of the seat enables energy
efficient cooling and heating
✓ In winter conditions the smart seat
enables to lower the cabin temperature
while keeping the same passenger
comfort
✓ In summer conditions the seat reduces
sweating of the passengers and
enables to increase the cabin
temperature while keeping the same
passenger comfort
Workshop “Solutions to electromobility challenges”, 18th October 2019, San Sebastian (Spain) 13
Key Results
3D Cabin Model including the Virtual Comfort Dummy:
✓ Enabled detailed investigations of the
thermal comfort in the cabin for different
setups (heating and cooling conditions,
different velocity fields etc.)
✓ Use of VR glasses to observe result
details in the passenger cabin
Workshop “Solutions to electromobility challenges”, 18th October 2019, San Sebastian (Spain) 14
Key Results
Eco-Driving and Eco-Routing:
✓ Eco-Driving evaluates the driving style by means
of a score and thus teaches the most energy
efficient driving style for a specific journey
✓ Eco-routing navigation aims to find the most
energy-efficient route in a vehicular road network
to travel from an origin to a destination.
Workshop “Solutions to electromobility challenges”, 18th October 2019, San Sebastian (Spain) 15
Key Results
Regenerative Shock Absorber:
✓ The Regenerative Shock Absorber (RSA)
enables energy harvesting by converting
kinetic energy of the damper to electric
energy by means of an hydraulic and
electric motor
✓ Two prototypes of RSA were designed,
manufactured and tested at the bench
Workshop “Solutions to electromobility challenges”, 18th October 2019, San Sebastian (Spain) 16
Key Results
Photovoltaic panels:
✓ The flexible photovoltaic panels enable
energy harvesting with the placement on
different locations of the car body
✓ A sophisticated control strategy by means
of dedicated DC/DC converters with a
centralized maximum power point tracking
(MPPT) algorithm ensure the maximization
of the harvested power
Workshop “Solutions to electromobility challenges”, 18th October 2019, San Sebastian (Spain) 17

in-vehicle testing of the following
technologies:
✓ Eco-Driving
✓ Eco-Routing
✓ Compact refrigeration unit
✓ Thermal management system
✓ Smart cover panels
✓ Smart seat
