TO PUT IN INTO PERSPECTIVE, ON A 0-100% SCALE, IT LOOKS LIKE THIS:

The way to measure this is to do a full charge (100%) and then check the EPA rated range (in North America) or typical range (in Europe and Asia/Pacific). In the plot, these numbers are then compared to the range numbers the car displayed when it was new. For example, for the 85 kWh Model S85 variant, this is about 400 km typical range or 265 mi EPA rated range. Even though this is mostly a reliable method, sometimes the computer in the car can’t accurately estimate how much energy the battery holds and might display an inaccurate range number. To improve accuracy, it is a good idea to run down the battery to almost empty and then charge to 100%, once a month. This is known as rebalancing the battery. However, the battery shouldn’t be left at 0% or 100% for more than 2 hours. The data collected by Merijn, also includes how many Supercharger visits were done, among other details. See the forum for more information, or if you want to upload your data. Besides Mileage vs Remaining Range, the file includes two other charts: Charge Cycles vs Remaining Range and Battery Age vs Remaining Range. From literature and research we know typically that 80% of battery capacity remains after 1000-2000 full cycles, strongly dependent on the temperature of the batteries. The data below support these numbers.
