The Clean Sky 2 program, part of EU Horizon 2020, is the European approach to address aviation sector challenges that come about with globalization, climate change and scarcity of resources. Clean Sky 2 technologies are expected to cut fuel burn & related carbon emissions by 20-30%, reduce noise levels (compared to 2014) by a similar amount, and to significantly improve competitiveness and mobility throughout Europe.

LiBAT, a project initiated under the Clean Sky 2 program, focused on research and development of a light, compact and high voltage lithium-ion battery for aviation applications. In collaboration with LiBAT consortium partners, LION Smart successfully developed a new HV battery system capable of powering a manned aerial glider. Our role in the project included system design, prototyping and testing of the battery pack. When developing battery systems for electric aviation, size, weight and thermal management pose serious obstacles in the design process. The LiBAT demonstrator constructed by LION Smart, which featured innovative battery systems connected to an electric motor and propeller, addressed these issues through an exceptional level of integration and combination of advanced technologies.
Integration of multi-level inverters
Immersive cooling and thermal management
Tunable AC battery system
Relatively lightweight and low volume
High energy density and storage capacity
Modular and scalable
LiBAT demonstration at the LION Smart test laboratory in Garching. The LiBAT battery powers an electric motor with propeller attached. Powers of up to 3,25kW with currents up to 30 A peak value were achieved at 2860 rpm in the tests.
While the project design was focused on powering electrified gliders, the LiBAT system also holds potential for use in hybrid propulsion systems, flexible frequency auxiliary networks, electric and hybrid cars, electric air taxis, and power tools (among others). However, the use of multi-level inverters for mobility applications is a potential game-changing technology that could transform battery systems in the avionics sector and beyond.
