Also, the "extension cord" from car to AC source does not need to be "HOT" when plugged into the car. Plug into the car first, then plug into the hot AC power "Socket", just like one does with boats and RVs.
The whole "danger" thing is overblown, mostly made up. No real statistics to back it up.
Apparently toasters, refrigerators, lamps, and carrying ladders are each bigger hazards to life.
Did you look at the comment on the West Marine page you referenced? "Shore power adapters, which allow you to plug in a variety of cords to a marine power center, must be used carefully or they could inadvertently create a shock or electrocution hazard."
These things don't have breakers sized to protect the cables, and don't have GFCIs. They CAN be safely used because the boats have safety gear installed. Should Nissan install EVSE functions under the hood so we only need to use an extension cord?
I lived in England and Germany for a total 7 years. Yes - 220V 13A outlets are easy to use, with and without adapters or transformers. But we're not talking 13A supplies with a L2 EVSE, are we? Euro plugs and sockets are rated for many disconnect/connect cycles - how many times can we safely connect a US dryer plug?
Either we want to promote electric cars or we don't. If we don't care, then let's keep harping about shore power plugs and roll-around EVSE - safety and class-action lawsuits be damned.
If we want to get EVs into the hands of nearly everyone, then we need to make it safe for the 14 year old kids and the 22 year old mother of two juggling the kids and groceries and trying to remember where her keys are. I could keep a couple of days work in my head before my son arrived - now at 47 with a 7 year old I have been known to leave Legos on the roof of the car... Things happen. We don't want it to happen with an EV.
I really hope that future EVers won't be limited to 50+ year old empty-nesters with a medical clearance confirming no Alzheimer's or adult-onset ADD!
