From the information on the Ford web site, the MachE will come with, at no extra charge, a 32 amp/3 amp charger.
The charger is a level 2: to charge at 32 amps will require a 240 volt with a 40 Amp breaker. The 3 amp you can plug into any 110 volt socket. This can be plugged in and is portable.
The Ford charger at 48 amps is an extra cost, price not yet published, and must be hard wired. The maximum you can use a socket is a 40 Amp charger.
Where I live on Long Island the electric company gives you a $500 rebate against the cost of installation of certain charges, The 40 Amp Juice Box, recently at Costco for $549 is included. To qualify you must submit a bill from a licensed electrician showing the installation. Right now the 32 amp charger from Ford is not on the list - but that might change!
I am thinking of doing this installation, as the extra cost above the 32 Amp Ford Charger will be $49 for the juice box and the cost of a 50 Amp instead of a 40 amp breaker. In both cases I will use #6 wire so labor and materials will be the same. So for under $100 I will go from a 32 amp to a 40 amp charger.
Hopefully this may change and the Ford 32 amp will be included.
If not, I can either leave the Ford charger in my trunk or sell it on Ebay!
Hope this helps.
