Here is a real photo report from Arnaud. Thanks a lot to him !
It seems to be a 79kWh pack with a little degradation no ?
He will watch with SMT as soon as he has it installed (- at the moment his splitter cable is in order).
Batterie de 82 kWh sur la Model 3 Grande Autonomie version 2021
Calculates to 78.1kWh.
To me it just looks like a 77.8kWh pack, pushed to the limit. Which is not surprising given the old part code (it's the
same part number as the other 77.8kWh packs, just with a different revision number...so we wouldn't
expect it to have the new 2170L cells).
I'd be sad if I were him.
Unfortunately his picture was not taken in "Drive" or unlocked state, so we can't see how much regen he has. As we know, it's possible for there to be a software lock on a pack that actually has more capacity, and there's no way we would know, without SMT, or paying attention to the regen at 100%.
But I suspect he has nearly no regen at 100% and has a 78kWh pack with no hidden capacity. But we will see what SMT says (maybe).
I have no idea how this is ok for the Performance. Maybe the WLTP test in Europe for the Performance was done with a 78kWh battery? (I haven't tried to work out the numbers, working back from EPA efficiencies, and comparing to prior WLTP results for Performance, to see whether that is plausible.)
Pretty sure we will never see such a pack in a 2021 Performance in the US. (Unless they do a new Performance- EPA test.)
