Tesla model Y 4680 battery pack not very serviceable!

<< < (6/15) > >>

Miyuki:
Tesla is actively anti-repair, ever was, and they are just getting better at this as getting more experience.
And if they will go with it and people still buy it. It will be just an inspiration for other manufacturers.
It is a sad world.

I wouldn't say they are anti-repair, that is where the company does things for no reason other than to block repair.

But yeah, lots of issues with repair definitely

Why not?  At 80kWh capacity per charge and 5km/kWh 250,000 km is 625 cycles.  A good Li-Ion pack will do 1500 cycles easily, a very good Li-Ion pack can do 3000.

Whilst these figures do sound reasonable, that graph alone doesn't give us enough information. Is that across all owners worldwide or within a specific region?

I'd love to see how long those batteries last in Australian summer temperatures. Nissan's claim of 80% usable battery life after 5 years didn't apply to the Australian market where there are reports of batteries losing up to 20% capacity within 12 months (granted it was probably based on the old battery design). Nevertheless, it's not unusual in parts of Australia to experience daytime temperatures of 40 degrees C and above. The average January temperature in western Sydney is over 31 degrees.

tom66:
Nissans battery had absolutely no cooling, not even a fan to blow air over the cells.  It's no wonder when parked in a country that regularly exceed 40C that the cells deteriorated.  A secondary issue is that the cell chemistry is very poor.  Like, it's one of the worst chemistries you could have used for EVs.  It's baffling to me that they used it for so long - and even the 40/62kWh packs use a very similar, slightly tweaked chemistry (still not cooled, mind).

That Tesla graph is from the Netherlands, so could be under-reporting high temperature degradation.  This graph is from the US:


I'd roughly estimate 80,000 miles = 4% degradation but the data is more limited.  That does put the car at worst case ~12% degradation by 200k miles, making a linear interpolation.  More data needed to make a solid conclusion.

They used aluminium welding in the Model 3, which 95% of reapir shops have no equipment to repair.
They offer no replacement parts to be ordered by third parties.
Flash memory is broken and you need to replace everything in your dash for 1500 or whatever it was.
Recently my bosses Model S tripped the circuit breaker 2x, each time it was 5K to fix the internal charger of the car, because it was out of the 2 year warranty. I had to ask this twice, because I got used to 6-10 year warranty on Japanese cars.
