Extending Battery Life Beyond the Road
There is a compelling alternative to recycling electric vehicle batteries that have reached the end of their automotive life cycle. Instead of undergoing a complex recycling process to merely salvage some materials, these batteries can be repurposed. Specifically, they can find a new lease on life in large-scale energy storage systems, aiding in grid stabilization.
Cost Savings and Environmental Benefits
These reused batteries are a boon for operators of stationary storage facilities, who can purchase them at a significantly lower cost—between 60 to 80 euros per kilowatt-hour, as opposed to the 130 to 150 euros for new units. The reduced strain on these batteries in their new environment slows degradation and, in turn, mitigates the sizable carbon footprint associated with battery production, which accounts for a large part of an electric vehicle’s lifetime emissions.
Circunomics’ Market Solutions
Circunomics has established an online platform that facilitates the sale of used batteries from automakers to industry customers such as storage system operators. However, gauging a battery’s remaining life, or State of Health (SoH), has traditionally been a costly and time-consuming challenge, requiring substantial testing.
To address this, creators Jan Born and Felix Paul Wagner have introduced an artificial intelligence-driven process that assesses battery SoH, utilizing data harvested from onboard battery management systems. This innovative approach can accurately determine how much energy a battery can still retain, based on its operating history and diagnostic data.
Matching Batteries to Applications through AI
Artificial intelligence does not stop at evaluating battery health; it also aids in matching used batteries to the most suitable applications. For instance, grid stabilization may only require brief, low-intensity charge-discharge cycles, whereas storing renewable energy might be more demanding. Circunomics’ marketplace is already showing results, with significant volumes of battery storage being traded and major automakers engaging in the second-life battery space. This initiative aligns with the forthcoming EU regulations that prescribe meticulous tracking and reutilization of battery components, underlining the shift towards a comprehensive circular economy for battery materials.
Key Questions and Answers:
– What are the benefits of repurposing used EV batteries?
Repurposing used EV batteries provides cost savings to energy storage operators and environmental benefits through reduced need for new materials and lower carbon footprint associated with new battery production.
– How does Circunomics’ platform work?
Circunomics’ platform acts as a marketplace, connecting sellers of used EV batteries with buyers like stationary storage operators. They use AI to assess the State of Health of batteries, facilitating the transaction process.
