Austrian Institute of Technology to develop improved battery management system
The researchers plan to improve the efficiency of EVs and the longevity of their batteries with the new system, focusing on lithium-ion batteries. Specifically, the institute writes: “These measures create a framework that enables more accurate prediction and control of battery health,” which will “deliver higher performance, improved safety and longer battery cell life, resulting in overall optimal utilization of the battery system.”
Under the project’s current design, AIT will develop the battery management system, “on the basis of fundamental knowledge and experience with the physico-chemical processes of lithium-ion batteries,” and then assemble complete battery module prototypes including battery cells and sensors. The prototypes will then be tested under various operating conditions to verify the implemented safety functions and the detection of faulty cells within the module
“NEXTBMS aims to develop solutions for the next generation of battery management systems. The project contributes to achieving the optimal use of battery systems, extending their service life and reducing costs through more efficient use of materials,” said Project manager Hansjörg Kapeller, adding: “It supports systemic changes towards environmentally friendly mobility solutions. This benefits both the environment and end users.”
Last year, the institute also announced plans to improve the battery ecosystem by developing a cobalt-free battery, as well as analyze the development of cobalt-free batteries with high power density for road and air transport. The project aimed to create a cell with an energy density of 390 Wh/kg and a service life of at least 2,000 charging cycles.
