EU funding

6.39 Mio €

Project

duration

June 2015 – August 2019

Number of

partners

15



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


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


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


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


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


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


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


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.


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


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


Key Results

OPTEMUS Demonstrator Vehicle (Fiat 500e):

✓ The OPTEMUS Fiat500e enabled the

in-vehicle testing of the following

technologies:

✓ Eco-Driving

✓ Eco-Routing

✓ Compact refrigeration unit

✓ Thermal management system

✓ Smart cover panels

✓ Smart seat


Impact on energy consumption and

driving range of the Fiat500e


Achievement of Project Objectives



Eco-Routing:

Eco-routing navigation aims to find the most energy-efficient

route in a vehicular road network to travel from an origin to

a destination.



Eco-Driving:

✓ Eco-Driving evaluates the driving style by means of a score and thus

teaches the most energy efficient driving style for a specific journey


Summary

✓ A short overview of the OPTEMUS project has been

given

✓ The key results of the project have been presented

✓ The impact on energy consumption and driving range

of the Fiat500e has been demonstrated
