Comparative Insights


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. 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 green band in this module shows the typical range variance we project for comparable models. Your vehicle’s location within this band may change month to month as we continue to gather data on comparable vehicles that helps us refine the shape of this band, and as your vehicle ages. It does not necessarily indicate permanent changes to battery health. 

It is OK to occasionally see your vehicle outside of the variance band and may be due to recent temperatures or other external factors. This will happen more frequently for models that are underrepresented in our data set, since the relative weighting of each vehicle will be higher.
