The existing approach to assess the State of Health (SOH) of electric vehicle (EV) batteries involves a time-consuming and costly  method. The industry standard is a full  charge and discharge to get a capacity measurement. This process is labor-intensive, and requires specialized equipment and expertise. This is not scalable for the millions of batteries that require real-time insights into the battery's condition. This gap between testing and real-world performance underscores the need for a more streamlined and efficient solution.
