My apologies if this has been discussed, but I did a search and didn’t see anything on it. . .
About a 18 months ago, I was in a 2014 Model S P85+ loaner while the Roadster was getting its annual. On a road trip, I ran the battery down to -2% rolling up to a Supercharger. When I plugged it in, she soaked up the charge like a desert sponge. Fast forward to last week. I did nearly the same thing (ran down to +3% SOC) on my own 2017 Model S 60 that’s a few months old. She barely took on any charge for 15+ minutes (yes, 15 mins). Same exact Supercharger, same 70 degree clear weather. I decided to move the car to another Supercharger (neither being shared in both cases). It still sat taking on very little charge for 5+ minutes so I panicked. I called Tesla and explained the situation to the letter. They told me that I’d need to be towed. Of course, I’m ready to go through the roof. As the call dragged on, the charging began to ramp up! As I’m conveying the improving state of affairs, the gal on the phone (with a technician in the background) began to say that this is actually expected b/c with such a low SOC, it would trickle charge “for a while” and then start ramping up. Well, it finally got into the 90+ amp range and after 90 mins total between both chargers, I was ready to go with exactly 200 miles (although I still could have taken on more).
First: if this is the way of the world, how does such a simple question not go quickly answered given I had the facts ready to go for the attendant and presumably the technician? Why stress me with the possible tow?
Second: this experience flies in the face of wanting to run the battery down further to get the strongest (quickest) charge to be most efficient on road trips <gospel that I took from the “How to save a lot of time on long trips” sticky thread>. Has something changed?
Third: what of the 2014 P85+ loaner that took on a huge charge immediately in the exact same scenario? Did I dream that? I don’t think so b/c I remembered only being there exactly one hour and I had well north of 200 miles when we got back to the car. . .
