Maybe 11 kW is 240V 48A. I have not heard of an EV with 45A max charging rate.
@emtonsti may be right that the spec isn't really for US.
Anyways, 48A will require a 60A electric circuit and hardwire. That's probably more hassle than worth it. I would get a 32A or 40A charger. Common brands include Clipper Creek, JuiceBox, Grizzl E. A 40-amp charger from a reputable manufacturer costs $400-600.
There's a 30% federal tax credit (up to $1000) for EV charger installations this year. The tax credit is currently scheduled to expire at the end of the year. It may or may not be renewed. Look up IRS 8911. (I'm not an accountant. I'm not an lawyer. Don't take my words for it.)
There's also a chance that the car may come with a charger. But it looks unlikely. VW didn't mention it in press release. And the charger that eGolf came with is pathetic.
