on trips from SD to the Bay Area, I have done charges in the Santa Clarita valley to avoid the issue of lines / broken chargers on I-5 in the Central Valley. I can generally make it from there to the Bay Area without another charge (GT with 19” wheels), and due to the EA issues, I have actually never stopped in Kettleman City because it has always been full, or all the “not broken” chargers are in use. I have stopped at other stations along that route, but have encountered issues more than half the time. Now I try to avoid charging in the Central Valley if at all possible.
In addition, going on long trips across the country, have always tried to charge at a stop earlier than necessary. That way if there is an issue, I have enough juice to make it to the next one. I end up stopping more, but with less “working charger” anxiety. I am hopeful that at some point in the future with better infrastructure, I won’t have to do that.
