Quick and Reliable Lithium-Ion Battery Health Characterization

Quick and reliable Li-ion battery health characterisation

Objective

• We propose to develop characterisation methods to quickly and reliably ascertain the state of health of batteries, their components, especially cells. Especially with the cells, the key aspects of the cells that contribute to its health and can degrade significantly, is to be characterized.

Description

• Development of Li-ion-chemistry based batteries, along with advancements in Power Electronics have enabled the evolution and mass adoption of Electric Vehicles, Energy Storage Systems, Portable computers, Mobile Phones and more such devices with carried energy, and advancing human lives, However, the rapid transition and mass adoption of electrification of transport vehicles is limited given the challenges Li-ion cell chemistries face. They degrade in multiple ways and much faster than rest of the vehicle. The batteries can also get into a thermal runaway reaction and result in fires that are difficult to contain and put out, Much engineering, research and innovations are resulting in the improvement of the batteries against these challenges. The projected improvements would not only help overcome the challenges mentioned, but also improve performance and costs well ahead of the Oil vehicles.

Impact

• Reduce time taken to assess battery health and life, Improve on board diagnostics during use of these batteries, Enable development of local industry in test and process equipment.
