Model 3 Hatchback would be nice in Europe, but to really compete with BMW and Audi a StationWagon/StationCar (or Shooting Brake) would be even better!

Attached shows my four year Rated / SoC Percentage, as can be seen it has lows at winter and highs in summers, but not your 6.5 km variation.

MeToo! My S 70D October 2015 is A-okay, only unwanted 'degradation' is the 10-15% slower Super Charging. As an Electronics Engineer, I always wondered how Tesla could expect that boosted charging up to 1.5C would NOT effect longevity and degradation of their super high capacity cells. I would...

Nope, this is very clear because of cases in 2016-2018 where the 'ombudsmand' had to pull back and acknowledge the 3 year 'to old claim' limitation..At my cars 4 years warranty expires check, my local SC told me that my MCU (replaced under warranty at age 2,3 years) has warranty untill 6.3...

Depends on local rules. Here in Denmark, a part replaced under warranty receives a new warranty with period equal to the original warranty period, but with a 3 year limit due to another Danish law regarding expirations. So here your replaced part will have a new 3 year warranty.

Wouldn't a possible replacement strategy be that non P models gets the - assumed - 350V pack and P models the refurbed 400V packs? For the same power at 350V as at 400V, the current draw is 15% higher, which could be above what wiring supports.

The published paper Error - Cookies Turned Off has an interesting section: 4 | SUGGESTIONS FOR FUTURE RESEARCH 4.1 | Impact of GITT During our capacity data analysis, we observed a significant increase in capacity after conducting a GITT procedure (Figure 12). This is due to the slow discharge...

Hmm, I use the exact same batteries for my fossile car 12V battery maintenance charger:) These I charge with 1/3C from 10-60% SoC to preserve battery life. I would never consider charging like UC do and I would not state, that the charging protocol that UC implemented mimics Tesla Fast...

No fun intended! This is a functional error, not an unwarranted and uncovered degradation issue - go get a new battery!

The car shutting down BEFORE reaching 0 miles Range is the reason Tesla Bjørn had battery replaced on his Tesla Model X. Why is this not covered by warranty?

You are twisting my words. An unneeded degradation would be if there was another way of charging equally fast with less degradation? The BMS assumed a higher remaining capacity than actual remaining capacity. Possibilities are many: - Degradation from High Current charging likely under...

Potentially a little side track here:) Tuesday, while driving a constant 110 km/h with AC1 engaged the Trip Consumption meter showed the attached, that is full throttle for approx 10% of the 25 km shown. 2,5 km at 110 km/h is around 80 seconds and calculating backwards, to reach Avg Consumption...

Yes a very bad SC answer! Lots of Panasonic Li-Ion 18650 cells are tested and certified for 1C CCCV charging, which would be 78 kW on a Model S 85. High Energy Density cells improve lifetime when charging slower, but most flattens below 1/3 C, so going lower brings little. Charging at 38 kW...

The wiki fpr this thread links to Keils Paper on 'Aging of Lithium-Ion Batteries in Electric Vehicles' The paper investigates means to proplong BEV battery life to 'wanted' 2000 Equivalent Full Cycles in Year 2025 and concludes that 1000 EFC is already possible for a BEV charged at reasonable...

Good point! If the new 'nerfed' speed is similar to Peter keil's 'Reduced Boost Second SUC' protocol, you can now SUC double as much with the same degradation I hope the German engineers are busy measuring recovery effect after super charging. Untill -hopefully that - here is a best case...
