Cell Monitoring Solution Looks to Extend Useful Life of Batteries & Support the Circular Economy
11 October 2023
The patented Chip-on-Cell technology that has been developed by Edinburgh-based fabless semiconductor vendor Dukosi aims to help prevent the large numbers of EV batteries now being produced from becoming a major environmental burden for our society.
Rather than data just being acquired on the battery pack, this approach goes down to a more granular level. Throughout their lifetimes, individual cells are monitored using attached chips - with temperature, voltage and current parameters all being continuously acquired. This means that complete visibility about a cell's operation, how it was shipped and stored can be accessed using near-field wireless communication. The upshot is that it is possible to determine the operational performance of each cell within a pack, and assess its suitability for use in 2nd or even 3rd life applications.
“Consumer adoption of electric vehicles continues to grow as the world moves toward greater electrification and transition to net-zero emissions,” notes Nat Edington, CEO of Dukosi. “Considering the potential of over 100 million EV batteries coming to end of life in the next decade, designing batteries for sustainability is an economic, social, and environmental imperative. We are already seeing adoption of regulatory requirements for traceability at the battery level, but full traceability can only be achieved at the cell level, the smallest unit of the battery system, to achieve a truly circular economy.”
