I uploaded the specs as an image file. I find it easier to read the post when the image it refers to is inline.
Some things we can work out from these specs.
The weight of the battery pack ( with heating plate ) = 38300 / 112.4 = 340.75 kg
This is 25% heavier than the previous pack. 271.8kg
The overall energy density of the pack hasn't increased, even though the actual cells are roughly 25% more energy dense.
I think this means it is the cooling system inside the battery pack that adds the weight.
Having liquid cooling doesn't just add extra cost, it also adds extra weight.
Nissan has chosen not to add liquid cooling to the new 62kWh Leaf.
This might be a good idea if the car is only to be sold in mild climates such as Norway.
The current Ioniq is not suffering from battery degradation. It does not have liquid cooling. Hyundai does not try to sell this car in Arizona.
The current car has a lighter, relatively more powerful battery. The new car has a larger, heavier battery, with a more powerful motor.
It will be interesting to see the new car tested to see how it actually performs. I have sat in the new Ioniq but haven't driven it.
