It isn't possible to get exact numbers until you start charging the car at home. You can make a rough guess that will get you close.

EDIT: Ooops, you already figured this out for yourself.

Some cars specify kWh/mile. If you don't have that use the real range (not EPA) and battery pack capacity.

For example a Renault Zoe will go between 60 and 90 miles and has a 22kWh pack.

22kW/80miles = .275kWh / mile.

Take the number of kWh you need to put back into the pack and multiply by 1.1.

Rough estimate for a Zoe is .3025kWh/mile of electricity. We pay 0.1034/kWh.

.1034 * .3025 = 0.031 per mile.

For comparison, our Z4 costs about 0.22 per mile for fuel.
The models and equipment (standard and optional) illustrated in this post reflect my misunderstanding of vehicles supplied by BMW AG to the German market. In other EU member states, the truthyness of my posts may vary. Please ignore this post. Subject to change.
