AIT Austrian Institute of Technology GmbH

The AIT Austrian Institute of Technology is Austria’s largest research and technology organisation.

As a national and international hub at the interface between science and industry, AIT enables innovations thanks to its scientific and technological competencies, experience in markets, close connection to its clients, and an excellent research infrastructure.

AIT provides research and technological development to realize basic innovations for the next generation of infrastructure related technologies in the fields of Energy, Low-Emission Transport, Health & Bioresources, Digital Safety & Security, Vision, Automation & Control and Technology Experience.

The Republic of Austria (through the Federal Ministry for Climate Protection, Environment, Energy, Mobility, Innovation and Technology) has a share of 50.46%, while the Federation of Austrian Industries owns 49.54% of the AIT Austrian Institute of Technology.

The increasing environmental awareness in today’s society and the systemic changes currently taking place require environmentally friendly mobility solutions and will create new business opportunities for innovative companies in the coming decades.

For faster market penetration and to increase the share of electric vehicles (EVs), AIT offers holistic solutions for the virtual design of environmentally friendly vehicles. The range extends from vehicle design, prototype development, system analysis and modelling to testing and validation. For AIT, XL-CONNECT therefore offers the opportunity to create new knowledge and to contribute to solutions for the establishment of smart charging technologies, as the increasing number of EVs represents a major challenge for the energy system in Europe.

AIT is responsible for the creation of an updated requirement overview for advanced charging concepts to be developed in XL-CONNECT.

AIT develops physics orientated 1D models of EVs including heating, ventilation and air conditioning (HVAC), taking into account preheating strategies and different driving cycles. The EV models are equipped with 1D electro-thermal battery models (developed by AIT) including various aging models for different cell chemistries. The battery degradation mechanisms and the main stress factors of different cell chemistries are validated by performing characterization tests. AIT will design and develop robust control mechanisms for the sub-component modeling of the thermal battery and vehicle system.
