Carging an electric car
Posted: Tue Jul 30, 2013 9:55 am
As a true petrol head, I have resisted for a long time, but I have finally given in: I have ordered an electric car.
Unfortunately electric cars are only usefull when you charge them. Our town has a great program that offers to install a charger with a reserved parking space right in front of your home. Unfortunately, other people are allowed to use this spot too and even though we don't have any other electric cars anywhere near to us, I'm just not looking forward to other people charging their cars in front of my house. Besides that, electricity costs €0.25 at a public charger, while it costs €0.22 on my home connection.
Unfortunately my home connection is very powerful: Only 1x 45A, and on that connection we already have a couple of heavy users, such as an induction stove, laundry dryer, etc. The connection can be increased, but because it enters our house right in the center, that would mean removing the concrete floor in our hallway, not looking forward to that either.
So a second connection comes into the picture. That will cost €750,00 to install and €200,00 annually. I would consider that, but there's a caveat: Half of our electricity prices are taxes. For annual consumption up until 10.000kW/h these taxes are €0,1423 per kW/h. Above that, these taxes drop down to €0,0530 per kW/h. That's almost €0,10 less! And out annual consumption without electric car is already 8.500kW/h, so with an electric car, we'll for sure break that 10.000kW/h barrier, cutting off almost half of our electricity price above that barrier!
So does anybody know the answer to this question:
If a house has two electricity connections, does the 10.000kW/h barrier apply on consumption on each of the two connections, or on consumption on both connections togher?
It really makes a big difference, because I expect to consume well over 10.000kW/h a year on charging the car alone, and 10.000 * (€0,1423 - €0,0530) = €893 annually.
