Electric vehicle energy stores: eStorage2 (VTT)
eSTORAGE2 creates an internationally significant expert, testing and research network and infrastructure for energy storages used in electric vehicles or in stationary applications, and the testing and development of electric commercial vehicle powertrains. Energy storage development has a pivotal role to play in making electric vehicles and working machinery more common. It is the objective of eSTORAGE2 to assist companies in their R&D activities, as well as generate and maintain research.
The energy storages of electric vehicles are a rapidly advancing field of technology. New battery chemistries and application areas herald new features, such as demands for cooling, heating and battery control systems. These demands are often critical regarding reliability and safety. It is one of eSTORAGE2's objectives to produce know-how related to these demands, so that expertise in the field may be developed and training activities expanded.
The eSTORAGE2 infrastructure and expert network formed by VTT and Aalto University enables the production of service-type support for companies in the development of their technologies and competence. eSTORAGE2 comprises all three levels of testing energy storages: the battery cells, modules and complete battery packs, as well as other types of electrochemical energy storages.
The electricity store: a critical component in electric vehicles
Every electric vehicle makes use of an energy storage and, within the ECV, the expertise and research and testing environment relating to such systems is included in eSTORAGE2. Know-how relating to the behaviour of batteries is an example of data produced through eSTORAGE2 for the benefit of all actors:
- battery design principles and selection for the application,
- battery cooling/heating (temperature management),
- battery control systems
- battery performance, service life and ageing
- reliability and safety.
The development and purchasing functions of companies can benefit greatly from the opportunity to examine new technologies together with scientists, as well as from the opportunity to test energy storages for their own products or customers under typical loads and conditions.
The expertise of eSTORAGE2 supports the selection of appropriate battery chemistries and batteries for the other work packages and corporate projects of ECV. The batteries used in all work packages can be tested and verified with the help of the eStorage2 infrastructure.
Parties in the work package
