Renewable energy and Energy efficiency
The widespread adoption of electric vehicles will require manufacturers to integrate smart capabilities into vehicle batteries. Researchers at CEA Tech institute Liten are developing sensors and measurement systems and installing them in test vehicles without disrupting vehicle operation. These tests provide data used in aging models to obtain more reliable gauges of performance and develop energy-management strategies for batteries.
This research leverages the electric mobility platform, which boasts a comprehensive range of equipment, from motor test bench to solar-powered charging stations and instrumentation. The tests carried out on this equipment are rounded out by the continuous tracking of a fleet of some 30 vehicles, providing valuable feedback.
ALL TECHNOLOGY PLATFORMS
The Poudr’Innov powder metallurgy platform is ramping up its strip-casting process for magnetic-phase synthesis, positioning Liten, a CEA Tech institute, as a leading developer of high-performance permanent magnets.
A test bench for high-power PEMFCs is now up and running at Liten, a CEA Tech institute. The test bench can characterize stacks up to 100 kW.
A characterization method using nuclear magnetic resonance (NMR) spectroscopy was developed to observe the formation of metal lithium in the electrodes of lithium-ion elements during operation. The insights gained will be used to extend electrode lifespans.
A battery abuse-testing platform recently set up in cooperation with Serma Technologies will put batteries to the test in extreme conditions in order to assess their behavior. The platform, housed in a dedicated building, recently completed its first tests on battery modules.
Differential voltage measurement was used to develop models that will enable more detailed characterization of lithium-ion battery aging.
How to collaborate with CEA Tech teams ?
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
