  1. If you want fast charging at home even in here in Europe where 3-phase power is common so you can get 16A 3x400 V (19.2 kW) connection pretty easily to the car, the whole electric grid connection of your house may become limiting factor in cost. Our house has "only" 3x25A connection to the grid and while it can be increased with a contract change, the monthly bills for the beefier connection get much higher fast. The initial grid connection for 3x25A connection costs about 1800 EUR (including all taxes) and if you want more, the beefier options are 3x35A for 2500 EUR, 3x50A for 3500 EUR, 3x80A for 5700 EUR or 3x100A for 7100 EUR. If you live further from the existing customers, expect to at least pay 20% more. In addition to that, you get to pay monthly fees for the max current you want from your grid connection. The basic 3x25A connection costs 20 EUR/month (including all taxes) whereas, for example, 3x50A costs 64 EUR and 3x100A costs 155 EUR/month. Of course, that 3x100A connection can only deliver 3x100x400 W or 120 kW so it's still pretty slow compared to proper fast chargers available with CCS connector. And as you can see, the costs of even 120 kW level fast charging at home gets pretty expensive indeed so it really makes little sense to fast charge at home. Going from 19.2 kW charging to 120 kW charging increases your monthly costs about 130 EUR and of course, the initial connection has extra 5000 EUR additional cost. And note that you have to pay these fees for the possibility of fast charging. The actual electricity for the charging obviously goes above the mentioned costs. Suddenly that 19.2 kW sounds pretty nice deal!

  2. The only bad part about the whole situation is that CCS connector with fast DC charging is so damn big. I wish Tesla would have allowed everybody to just use their connector because it's obviously superior to everybody else. The idea of putting the beefy DC charger outside the car is/was good and you need a beefy connector to handle the continous high load during fast charging but you only need two thick pins and communication channel.
