With a new 60 software limited at the top, but not with any other Tesla.I have see 50kw right up to 100% before also.

Well, you have the amps and the volts right there on the other side....Well.. well. Then how can that be true 100%. Ingineer had to explain this before he can say with certainty that it is bottom limited.
50kw near 99% means it is not true 100%.
Although now I am wondering if the kW rate we see on the screen is a running average just like mph value
That would be a big disappointment if it's bottom limited. I really like the idea of having full range without degrading the battery as much as a full charge would. I'll call and ask them about it.
Even easier, run a 60 most of the way empty then unlock it. If the charge % goes up it's bottom limited.
I've already volunteered my car if someone will simply volunteer the funds. I will even take time out of my schedule to get it rebadged. I'm 90% of the way to solving this puzzle. Who is going to help me the last bit?I called the service number on the website. It took ten minutes of trying to explain my question and what made the question significant. The conclusion was, that the guy I talked to, had no idea if the battery pack was 80% charged or 100% charge when the 60 kWh car's screen said 100%. Should I call and ask sales? I'm guessing they would be even more clueless, if that is possible. So, is anyone out there getting ready to pay for the upgrade to the 75 kWh?
It's very tempting to pay for your upgrade just to find out, but I'm kind of a tightwad. Maybe it's top limited now, but with the pack needing to be 100% charged a few times a year, for balancing, they might make it bottom limited with an over the air update. Maybe I should call the service center again and ask how I'm going to balance my batteries if it's not actually charging to 100%.
This would suggest balancing by charging to 100% is not necessary?
I was told by sales last weekend that you could charge a 60 to 100% without degradation of the pack and that supercharging would be faster due to the later taper.
I would still prefer something "official" from Tesla.I was told by sales last weekend that you could charge a 60 to 100% without degradation of the pack and that supercharging would be faster due to the later taper.
Maybe you can ask those people for help: Upgrade to 75kWhSo, is anyone out there getting ready to pay for the upgrade to the 75 kWh?
I was told by sales .....
And they will gladly offer you the full, complete, definitive Truth that has thus far been withheld from all others.I'll call and ask them about it.
I think we only need a 75 kwh Model S supercharger data to compare with soft-lock 60 kwh. All myth will be debunked. My personal bet is front 0-80% is same with 60kwh 0-100%, and last 80-100% is similar to S85/90I know it has been a long read but I finally feel like I figured it out, what do you think?
Ingineer, Randy Carlson at Seeking Alpha is speculating that Tesla is using a new chemistry to finally exceed the 4.2V threshold for their 60/75 pack. He wrote a long post about it here: http://seekingalpha.com/article/4001134-tesla-alreadyI've collected detailed data logs from a refresh 75 (not locked), but not yet on a locked car.
The 75 behaves exactly like the older 70's voltage-curve wise, with the exception that the new 75 charges with higher current and way less taper. I think this may be due to 3 things; improvements to electrochemistry, thermal management, and the doubling up on the bond wires that connect each cell to the bus plates.
Until I get real data myself from a new locked 60 pack, I can't state for sure, but evidence presented from several members here indicates that the pack voltage is at 352 volts when completing a 100% supercharge. This means 4.2v/cell, which is 100% charge. Going over that is instant damage to the cell. There has been a theory proffered by some here that Tesla/Panasonic changed the electrochemistry such that is supports a higher 100% charge voltage, which is highly unlikely due to the way voltage is established in the cell. Also, if this were the case, then I'd see it on the 75 pack. Nope!
