kWh used per charge and battery specs

[Alessandro]

Hello, all! My first post here!
Just curious, did you have any figures on how many kWh does it take to fully charge the i3 battery (for example, from a traditional 220 V, 3 kW socket) ? And which part of the total 22 kWh i3 battery is actually charged ?

Useable battery capacity is 18.8 kWh, and most EV chargers are approximately 85% efficient, so a full charge from "empty" should take roughly 22.1 kWh.
