Cox Automotive's EV Battery Health mobile app informs users of an electric vehicle battery's condition, along with historical battery data such as times, temperatures, and types of charges, and overall performance. The information is VIN-specific, and the company's health algorithm uses the data provided to create a battery score for the specific vehicle ranging from 1-5, which is then given to the user alongside the battery’s current estimated range in a unified report. Requires a Bluetooth dongle.
