I bought a 2015 a while back and loving it though I am ready for warmer weather/more range. I have never used my DCFC but did this weekend for a longer away trip. I was at about 30 percent and charged to 100 percent. I assumed it would stop at 80 percent but charged up to 100. I used a EVGO station, their app didnt work but the physical card they sent me did to start the charge. My question is does this just vary by location/charger brand? Do some stations stop at 80 and some go to 100? My car said finalizing after 80 percent but kept charging to 100. Whats expected? Thanx in advance
