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
New insights into the mechanisms that underpin the dissolution of the components used in lithium-ion batteries have resulted in the development of an improved recycling method.
A new hybrid polymer electrolyte technology with the capacity to enhance battery safety was developed for Solvay. The company has begun presenting the new technology to battery manufacturers.
A new software application capable of simulating how battery pack components’ electrical characteristics will evolve over several years has been developed by Liten, a CEA Tech institute. The software will be useful in accurately predicting battery pack performance over time.
Liten, a CEA Tech institute, helped develop and/or manufacture three types of batteries to power a terrestrial robot for France’s Directorate General for Armaments.
Leti and Liten, both CEA Tech institutes, developed the electronics and algorithms required to measure the internal temperature of a battery cell by estimating electrical impedance. The purpose of the solution is to detect the early signs of thermal runaway in embedded lithium-ion batteries.
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.
