Thanks very much for the news! My electrical contractor wonders whether all the Tesla charge cables protect the vehicles from surges. Do you have contacts who would know?
The Model S (and Model X) UMC that comes with the car (in North America) adjust to the types of plugs and supply to limit the charge. It is smart enough to see the load and adjust the rate downward.
For example, on our cross-country trip last year, when I spent time at my cousin's house (
day 10,
day 14,
day 15), the 110V connection worked at 1 mile per hour originally and finally found the sweet spot at 2 miles per hour (not the 4) because of the quality of electrical connection that he had (it was the longest run in the house.)
This capability was added after some of the much publicized Tesla Model S "fires" from years ago. (It's important to note that some of the UMCs sold in Canada are sold restricted to 30A, I believe (even with a NEMA 14-50) to comply with Canada's electrical authority or standards, (I'll have to see if I can find the source, this is years ago, I believe)).
