Scientists from the University of California, Riverside, have developed a new diagnostic metric for electric vehicles (EVs) that determines whether they can complete an upcoming trip.
Called the State of Mission (SOM), it utilizes both battery data and environmental factors, such as traffic patterns, elevation changes, or ambient temperature, to generate real-time, task-specific predictions. Furthermore, the team has developed mathematical and computational frameworks to calculate the SOM.
Literally every EV with Google Maps integration gives you estimated battery remaining upon your arrival at destination, assuming you use the chosen route, accurate within a few percent.
