There's nothing "normal" about a 220v plug. That's level 2 and will quire a wall charger (EVSE as someone has stated). Level 1 in the united states is 110v and other countries are probably going to be about the same. That would be considered "normal".

Household voltage in Belgium where the OP is is 230v / 50Hz. Not all electrical systems act the same, particularly for all houses in different countries. ( :D ;) )

Yep that is true, 220V / 50Hz .

In the meanwhile I asked a quote for the 3 phase connection from the electrical supplier.

I see. Wow, I had no idea. That's quite a lot of voltage.

We also can have 380V - 3F if we want but that is to expensive if you have no professional shop but if you want and willing to pay for it, it can.

FWIW, those sorts of supply voltages are available in the USA, too, but often restricted to commercial zones to share the extra costs. But, with enough money, you could probably get it anywhere. Depends on how far you are from higher voltages, which transformers are used, and how deep your pockets are.

I use the 110V outlet to charge my i3 or what is known as trickle charging to some. If my i3 battery is completed drained, it's about 22 hours to charge the battery from 0 to 100%. I get about 4 - 5 miles of charge per hour. On my last day of commuting to work I purposely let the battery drop down to 6.5% so the REX will kick in. Then I only drive about 8-10 miles on the REX. I think this is good practice to do at least a couple times a month so that the fluids in REX are being used and the 650 cc engine gets to run a bit. I'm sure most people would not want to wait 22 hours for a full charge on an EV, but honestly my i3 (94Ah) is rarely ever drained with no battery charge left. I just charge it over night maybe 8 - 11 hours or what ever is needed to get back to a full charge or close to it. For me this works out perfectly. Driving my i3 has been a great experience 8-)

@Geodude why not just code your car that REX can start from 75% ? that is much easier :)

Our 17 Rex takes 4.5 hours to charge on a dedicated 240V circuit(which was wired with really thick gauge cable and paired with a 50 Amp breaker) here in the US. The voltage on it fluctuates between 225 and 255V. Our i3 maxes out around 31 Amps due to its internal charging limit set by BMW. The math on our charging scenario with our Juicebox Pro 40 works out to about 33.4 kWh of energy pushed into the car including charging losses over those 4.5 hrs of time. Not all 220-240V outlets are created equal and the BMW salesman may have been a bit optimistic. Most existing dryer outlets in garages in the US max out at 30 Amps and are on a 30 Amp breaker, but can only safely provide about 24-26. I wouldn't push them higher for such prolonged periods of time so the charging equipment used should be limited below the max that the i3 can pull (32 Amps) else there's risk involved with wiring and breakers on existing circuits. I suppose there could be significant variance in wiring depending on country, local electric codes n such.

I'm really haven't needed to code my i3 to "hold the state of charge" after 75% because my daily commute isn't far at all. I just charge my i3 at night when I sleep and in the morning my i3 is smiling and ready to go !! Maybe down the road I'll look in to getting one, but for now it's all good. Thanks for sharing KrisM... 8-)
