We all know to help retain the life of the battery we must sacrifice range on daily charge to 90%. If the new Model S 70 is "really" a 75, would charing the battery to 100% really equal 93%? My question isn't if I should change to 100% regardless, just curious about how the artificial lowering of the battery capacity really limits the battery capacity. 70 kw * 90% = 63 kw 75 kw * 90% = 67.5 kw 75kw * 93% ~ 70 kw (75 kw * 90%) / 70 kw = 96% Therefore a 96% charge of a 70 kw (really a 75) is equivalent to a 90% charge of a 75 kw. The hardware should still balance the cells regardless of max capacity and if max capacity is actually higher than the amount you are "allowed" to charge there should be extra room for the cells to balance. Any thoughts? Again, this isn't a question of IF people should charge their new Model S 70 to 96% just more a question about the physics.
