I am shocked at the 2 miles/hour charging I get off a 110V outlet, and it makes my planning for overnight trips problematic, as overnight charging at private homes on 110 V is inadequate.
I have been toying with the idea of using a step up transformer, and it seems promising to me. Any engineers out there have thoughts on this? I have looked online at step up transformers, many of which aren't so expensive. If I used one to supply 230-240 V from a 110 V set of outlets when traveling or at work, do you think it would speed up the charging process? Would it be safe for the car?
It looks like you can buy compact models for 5-6 kW fairly cheaply. The car has a 10 KW onboard charger, so it would not exceed the car's capability. It this idea is feasible, it would really change things. The only problem I see is that finding two 110V outlets which are 180 degrees out of phase might take a little hunting with an extension cord, but it would be well worth it to get more amps into the car.
Any thoughts? Do I have a feasible idea here?
