Sorry for the stupid question, our first electric car 
So, I understand how I charge it at home, but what about charging stations on the parking lots etc?
My friend told me that I am supposed to apply for a card and can charge for free...After looking into it I guess it is only available for Nissan Leaf owners (he has Nissan)... Are there programs like this for Mercedes? Do I need an account of some sorts or just a credit card? And how much is it (+/-) to lets say fully charge a car on those stations?
Found one called evgo - is it a good option and is it accepted on all stations?
And if I charge at home every night - what should I expect $$wise my electric bill to be?
Thank you!

I am in the USA
