J1772
If you want to get your own J1772 cord for the house, it's ONLY $475, as opposed to $30 for an extension cord for 120v at home depot. haha. Dang! it's rated for 70 amps though. And built to order.
I find it really annoying that they would make a plug-in so complicated. I guess they are looking down the road when there will be so many plugs that it could negatively affect the whole electrical grid? So there would be some sort of priority given to the "more dead" batteries? Is that the reasoning behind it? Or is it just to make sure the plug can't come undone? Boy, if they try the charge sharing thing, I think it will take about 1 week before a person makes a crack for it, and sells a "charger" that charges all the way until full by faking signals.
