Every electric vehicle battery has a usable lifespan for transportation purposes. As the battery ages, it holds less energy (meaning lower range) and doesn't accelerate as quickly (lower power). We use a machine learning approach to compare each car to thousands of others to estimate the remaining lifespan based on its history and likely future battery degradation. Future predictions are uncertain because of variations in driving, charging, and external forces such as temperature.
The blue band in this module shows the typical range variance we project for similar vehicles. Your vehicle’s location within this band may change slightly month to month as we gather more data and continue to refine the shape of the band, and as your vehicle ages. It does not necessarily indicate permanent changes to battery health.
