We have been Coast to Coast about 5 times in our Model S and Model 3s and have hit 180+ different Superchargers. The variables are infinite on how long it takes for a Supercharger to actually come on line. We have seen some that took 400 days to get the permit approved (Fort Stockton, Texas), and others popped up working in about six weeks. The “political” attitude of the local authorities can make it happen tomorrow, or drag it out for months. COVID19 really adds another dimension of unknowns.
We were in Canada in September and the Eastern Superchargers were being completed in New Brunswick and Nova Scotia, but did not get turned on until the whole Trans-Canadian Network was powered up at once at the end of December 2019.
Across the continent we have watched the construction process get better and better, as they figure out it is better to get the transformer installed BEFORE they put the pedestals in. The precast pedestal bases have accelerated the completion time as well.
The V3 Stations are easiest to spot because the cabinets have the vent grills located on the upper section of the cabinet.
The thinner cables (liquid cooled) are not as easy to tell, but are a second clue.
We have seen some Supercharger stations pop up ON LINE with no time delays at all. Our tours have taken us from Prince Edward Island off the coast of Nova Scotia to Los Angeles and from Spokane, Washington to Tampa, Florida. So far we’ve driven about 130,000 miles and have had a ball.
We use the Tesla Supercharger Network almost all the time, (when traveling) but do make use of a few RV Park hook ups, so having a NEMA14-50 adaptor is a great accessory to carry with you. Interestingly, several of the RV places we charged at 3 years ago, ALL now have Supercharger stations located in those towns.
We drove 4,200 miles in late January-early February, going from our ranch east of Denver to Los Angeles, then to Austin, Texas and back to the ranch and the network made it a breeze.
Of course 98% of the time we just plug it in in the garage which is effortless.
The Superchargers will get there eventually, but understand, the issues are generally with the local utilities and their governing authorities that makes the time so uncertain.
