Gencis, I wouldn't read too much into the kWh put into the battery, as that might be a function of actual battery capacity. If you are interested, you might get the app CaniOn for Android and a genuine OBDLink LX or MX Bluetooth adapter, as that will reveal its battery capacity and individual cell status as well as a lot of operating information.
Yours is now the second North American i-MiEV that we know is in Eastern Europe!
ABB charging stations are also here in the U.S. and CHAdeMO is an international standard so I don't think that's an issue.
I personally try to avoid CHAdeMO, as our small battery takes quite a hit; nevertheless, it is a great time-saver when really needed.
