WP1 Requirements

Range limitation, due to the limited storage capacity of batteries, is one major issue in electric vehicles. The main challenge in this project is to achieve a systematic energy management of the vehicle, based on the integration of new electro-thermal energy management strategies and new subsystems, and focusing on solutions for solving the state-of-the-art major issues in electric vehicles. The energy consumption of the auxiliaries (e.g. climate control) and accessories, using part of the electric energy from the battery, are still worsening the global picture. In extreme conditions, up to 50% of the batteries’ capacity is absorbed by these subsystems. The systematic management of energy in electric vehicles is a mean to gain extended range without sacrificing comfort. The challenge is therefore to extend the range of electric vehicles in almost all climatic conditions. In this work package, the requirements of the concepts and solutions intended to be developed for the key subsystems in electric vehicles are specified.

WP2 Simulation and Modelling

Methodologies for the Design of Coupled Electro-thermal Vehicle Architectures The overall objective of this work package is to establish a comprehensive, in-depth quantitative understanding of energy flows in electric vehicles, with special emphasis on thermal energy, and addressing the state-of-the-art major issues in electric vehicles. New design methodologies and management strategies for the recovery and storage of the thermal energy with the aim to use it in the Heating, Ventilation and Air-Condition (HVAC) system will be developed. For this development, at first the derivation of energy flow models for all key power train components, including thermal, electrical but also mechanical energies as well as the thermal characteristics of the passenger compartment are needed. After a validation of these models, they will be used to design and optimize the vehicle’s energies architecture and to develop control algorithms for effective coupled electro-thermal energy management that will improve not only the energy efficiency of the powertrain but also the reliability and lifetime of every subsystem.

WP3 Electro-thermal Design of Powertrain Subsystems, Auxiliaries and Accessories by Using New Cooling/Heating Approaches

The objective of this work package is to develop solutions for enabling a novel interlinking and coordinated utilization of electro-thermally relevant subsystems on the overall vehicle level to constrain, structure and reroute electro-thermal energy flows. This is achieved with an approach balancing the integration and distribution of the electro-thermal network over the vehicle. Hence, the utilization of and exchange between subsystems contributing to electro-thermal properties can be optimized as well as the utilization of available computing power.

WP4 Control Algorithms and Platform for Highly Efficient Electric and Thermal Energy Flow Management

The objective of this work package is to develop algorithms, methods and technologies enabling a novel interlinking and coordinated utilization of electro-thermally relevant subsystems on overall vehicle level to constrain, structure and reroute electro-thermal energy flows. This will be achieved with an approach balancing the integration and distribution of the developed thermal and electrical control algorithms over the vehicle network. The utilization of and exchange between subsystems contributing to electro-thermal properties can be optimized as well as the utilization of available computer power. Vehicle level view on electro-thermal energy flows differentiate this project from state-of the art solutions, where this problem is usually either not solved or solved locally on subsystem level mainly due to system complexity. High interaction between the architecture top-level designers and the developers of the low-level components is needed.

Work Package 4 is led by Infineon Technologies AG.

 


 

WP5 Validation of the Subsystems, Performance and Robustness Tests

System integration and partitioning is more and more crucial to assure highest energy efficiency, improved robustness, cost reduction and less dependency from the suppliers. Critical points have been addressed individually in the previous work packages to provide innovative solutions for the thermal energy management in electric vehicles (e.g. new architectures, subsystems and materials for an optimized thermal management). The aim of this work package is to validate the developed thermal management solutions and subsystems (i.e. novel architectures, next generation of subsystems and components, optimized control algorithms), and to prepare them for being tested in an efficient way on test benches, and further in the project, directly in the two different classes of addressed vehicles.

Work Package 5 is led by VALEO EEM.

 


 

WP6 Vehicle Integration and Demonstration

The objective of this work package is to integrate the developed solutions in two different classes of electric vehicles: One in the A-segment and one in the C-segment. These vehicle classes have different requirements and topologies and provide a high market potential. The knowledge and technologies developed in the frame of the project can overcome the current state-of-the-art in terms of comfort, safety and certified performance. In almost all weather conditions, with minimal use of energy to keep passenger and battery compartment thermally conditioned, radical reduction of self-discharge and energy use of the battery is attempted.

Work Package 6 is led by IFEVS.

 


 

WP7 Dissemination, Exploitation, Standardization and Market Trends

This work package consists of three tasks to carry out the dissemination of the project results, their exploitation and exposure to the communities as well as the liaison with other projects, which have similar subject areas and objectives within Europe. A number of actions will be implemented to facilitate the dissemination of the project achievements, especially from the methodological point of view. Focus will also be put on creating a joint view on the emerging market for electro-thermal subsystems for electric vehicles. Work Package 7 is led by SAFT SAS. WP8 Project Management and Liaison The smooth operation of the project by implementing as well as proactively managing and improving all necessary processes related to communication management, scope management, project planning, quality management and risk management is covered by this Work Package. The responsibility is to ensure that the funding provided by the European Commission is utilized according to the H2020 objectives and put to maximum benefit for the project participants, the European community and all European citizens.
