I've been going through my EV charging invoices, putting them into a spreadsheet, and doing some calculations.
So far, I have clocked in around 1050 miles (1690 km) and have paid $128 in charging (mix of Level 2 and DC FC). That puts me at around $0.122/mile ($0.0757/km).
Granted, some of those charging sessions included sitting in the car with the AC and music on to stay cool. So, I ended up paying more since that siphoned some of the energy the car would've put into the battery pack.
If I take the average of highest tier gas (required for my previous 2017 A4 allroad) for the month of May of $5.35. At an average of 20 MPG (8.5 km/l), it would've cost me $0.2675/mile ($0.166/km).
