Charging your electric car

I assume the topic may be relevant to international readers also. Therefore this post is in english as you might have already recognized. :-)

As I mentioned in a previous post (in German) I'd like to buy an electric car. So I went to see and test the ones that seem to suit my needs. During my preparation for the test and also while I was driving a Hyundai Ionic two weeks ago, I found out the charging of the cars is not as easy as I thought. The problem is not a lack of charging facilities (in Germany). What bothers me most is the wide rage of charging types and charing times for the various cars. To find out what's really going on I've collected information for some cars, their onboard chargers, their charing power and time for the various charging types. This is an important topic for the everyday use of an electric car, I assume.

In Germany most charging stations in cities are Type 2. They offer up to 22 kilo watts (KW) charing power, which is pretty good. Unfortunately only very few cars are able to charge with 22KW on a Type 2 charger. This depends on the amperage (16A oder 32A) and on the number of phases (1-3) the car's on board charger can handle. 

If you charge at home with a wall box,  the charing power (and time) depends not only on the wall box and your electric installation at home, but also on the onboard charger of your car. If it can charge only with 1 phase on Type 2 then you will not get more than 4.9 KW out of your wall box at home (at least in Germany). This differs from country to country and depends on the regulations of the electric network and the legislation. In Germany 1 phase power consumption is restricted to 4.9KW to avoid unbalanced load on the electrical network (aka. Schieflast). This might be different in other countries.,

To collect the data in table below, I've asked the manufactures and read a lot of internet forums. If there is anything wrong, please send me the correct data. This is just a collection of data that seems relevant to me. I hope, you might find it interesting, too. The explanation of the rows is below the table.
