Are you talking about the battery meter? That is just EPA range * battery percentage.
The precise estimate is in the navigation system, when you navigate to a destination and it says you will arrive with X% left. This takes into account speed, traffic, elevation, temperature, wind, etc. and is usually pretty accurate for me.
