I have a Model S 85 2014 with only 53000 miles. I noticed that the supercharging rate has dropped off like most people on this forum, but my range is still OK. I took the car to Tesla service department three times and was told it’s the heat and the humidity, or certain Superchargers causing the slow charge. Being involved with Electronics design this could have some merit but everything was OK with the car last summer. It is easy to disprove those reasons by driving to three different Superchargers late at night when it’s colder and also when the charging stations are empty.
I dropped the SOC to 20 miles and visited three superchargers which were empty. All of the superchargers started in excess of 115kW but quickly dropped within 30 seconds to around 90kW and slowed down immensely.
I went back to Tesla and the technicians were at lunch and the service advisor took all my details and went upstairs to the technicians. She came down and asked when did I notice it. I said two months ago. Her reply was “well that’s when Tesla pushed the firmware “upgrade” to prolong the life of the battery”
I told her that’s not fair and she must ask the technician to phone me.
He phoned and basically said that Tesla has the right to slow the charge rate from the superchargers. I suppose they do have that right but it is not ethical. If the software had affected my range I could have made the point that Tesla don’t have that right. I told him I would like the matter to be elevated but no-one has contacted me.
I love my car and have done nothing but praised the company for four years. Now I am not sure if I can buy another Tesla. Tesla are damaging their name with the early adopters.
