Faster fast-charging and extended lifetime of lithium-ion batteries by new onboard monitoring of degradation using feedback from new cheap sensors

Faster transport electrification is vital to achieve the global target of carbon neutrality, and it depends heavily on its battery systems.

For a given installation, the main factors affecting the sales are the fast-charging performance and the battery lifetime.

With very limited sensors, today’s vehicle battery systems are treated as a black box, leaving the local states inside battery cells not well monitored and controlled.

The consequence of this is suboptimal performance and premature battery ageing associated with undermined reliability and safety.

In this project we will introduce and develop cheap sensors and develop intelligent algorithms for battery management systems that use the sensors in feedback to achieve accurate state estimations and faster charging without compromising on lifetime and safety.

This project represents a creative collaboration between the research groups Automatic control and Nanomaterial and Manufacture at Chalmers, Volvo Cars, and ConScience AB.
