Clean Sky 2 research project LiBAT demonstrates the propulsion performance of its exceptional AC battery system

In the last months, the LiBAT consortium has successfully tested its highly innovative AC battery system, demonstrating a power performance that is sufficient to maintain level flight for a manned glider. The lightweight, compact, and highly-integrated battery rotated an electric motor with propeller attached in a lab setting. The advanced LiBAT technology can be applied to a broad range of applications in the transport sectors, taking us a large step towards a more sustainable future.

October 2020: In successful integration tests the LiBAT battery was able to drive the propulsion unit with considerable power. Further details will be disclosed in an open access publication that the consortium is currently preparing.

July 2020: To ensure the best possible outcome of the LiBAT project, a cost-neutral extension of the project duration by three months was initiated and accepted. In this way, COVID-19 induced delays are mitigated and the integration tests for the battery can be performed under improved circumstances.

June 2020: Best presentation award for LiBAT on the ICEHAT 2020 conference. We have presented the LiBAT battery approach on the International Conference on Electric and Hybrid Aerospace Technology (ICEHAT) in Paris. The presentation was very well received by the audience and organizers, leading to the „Best presentation“ award for LiBAT. 

May 2020: To make the results of LiBAT available to the broader community, they will be shown on the International Conference on Electric and Hybrid Aerospace Technology (ICEHAT 2020) at the end of June 2020 in Paris. Our abstract has been accepted.

April 2020: Work in the workshop is taking up some speed again. First successfull tests on assembled battery strings.

March 2020: Corona hits us like anyone else. We will try to keep to the initial timeline. Workshop access at the different locations is limited or not possible at all. Ordered parts are considerably delayed. The EES 2020 was canceled.

Feb 2020: We intend to show the LiBAT results & methods on the Electrical Energy Storage (EES) conference in Munich (June 2020). An abstract was submitted.

Okt 2019: We have gathered in Garching close to Munich to review the LiBAT design. The LiBAT battery will be a highly integrated modular battery system, combining two innovative approaches: an immersed thermal management with the high-tech fluid Novec and modular power electronics in a Multi-Level-Inverter setting. Everyone is eager to get going and to see the behaviour in the real demonstrator.

Sept 2019: The consortium has extended the LiBAT approach towards the use of MLI technology. In this area we will be supported by Prof. Dr. Riley from the City University of London and Obrad Dordevic from Liverpool John Moores University.

Nov 2018: Project Kick-Off with TWT, Lion Smart and the topic lead, Dassault Aviation.
