Dukosi released an advanced chip-on-cell battery-monitoring platform that can help enable a circular economy by empowering reuse, repurposing, and recycling throughout the battery value chain. The intelligent chip-on-cell solution changes the way batteries are designed and monitored with a wireless chip on every cell to continuously measure cell parameters such as temperature and voltage.
An added benefit of this on-cell storage is that it provides lifetime traceability by providing the cell with a unique ID, materials provenance, and 24/7 data and event logging. The Cell Monitor IC enhances safety and performance throughout the life of the battery, from first-life applications such as electric vehicles (EVs), to second/third life usage in energy-storage systems, to end-of-life and cell recycling.
Designing batteries for sustainability is an economic, social, and environmental imperative, and enabling traceability at the cell level, the smallest unit of the battery system, helps to achieve a truly circular economy. Dukosi’s patented chip-on-cell technology provides a higher level of safety, performance, and efficiency throughout the battery value chain.
During cell manufacturing, the Cell Monitor IC captures provenance data and starts 24/7 monitoring and lifetime data logging of the cell’s voltage and temperature immediately. This promotes safer cell storage and transport, pack manufacturing, and warehouse handling, as well as providing improved aging predictions.
The solution allows for a more flexible pack design with improved maintenance by targeting the cells not meeting requirements. Granular and accurate data stored on cell enhances battery safety and performance, warranty, liability protection, and better residual value assessment. Because the provenance and lifetime data including event logging stays with the cell for its lifetime, battery utilization and safety can be improved in second- and third-life use in energy-storage systems and other applications, to end of the battery pack life and cell recycling.
