We’ve pulled into a few stalls that had slow to almost non-existent charge rate and sometimes also received messages that the charging stopped prematurely. Assume it’s a power or equipment issue. We also have been at SC locations that have been designated busy ones and had the system set our charge to 80%. For the most part the 80% will get people to the next charger where charging will be faster than waiting for a 80-100% charge so saving you time waiting to charge. I think we always received a notification about the restricted SOC level, and if need be it can be manually adjusted above the 80% once charging starts (and not needed I think if using the Trip Planner).
With the advent of so many more Teslas on the road traveling and needing to charge at SCs, it’s all about reducing the wait time for people needing to get back on the road. Any other reason is purely ridiculous as the owner can go to another SC and still charge again. I do like the aliens theory however. Maybe they’re from Mars checking out this guy Musk’s technology.
