I picked up my new model 3 a week ago and wanted to see what the maximum indicated range would be on a full charge. I was interested in seeing if the initial range would exceed 310 miles with a new battery. When I bought my model S in 2014, the battery would charge a little over the rated range of 265 miles and reach 270 miles for the first couple of weeks of ownership and then started to settle down at 265 miles for many months.
When I tried the model 3 on my HPWC, it only reached 305 miles (or 99% charge) before the charger shut down. The internal charger had tapered to 5 amps and the time remaining was stated to be 40 minutes when it shut off. I thought it might have entered a balancing state and that during that time it would slowly reach 100%---but it did not. After driving several hundred miles I tried a supercharger session with less than 50% state of charge. The supercharger only reached a maximum of 48 KW output and quite quickly tapered to the mid 20's before I terminated the session. One more attempt at a 100% charge gave the same results as the first time.
I usually charge to an 80% indicated state of charge so the need to have a full 310 miles of range doesn't make any difference. However, is there something here that I should be concerned about. The car is at the SC for an unrelated problem (Condenser fan shutters) so now would be a good time to bring this up if there is indeed a problem.
