We have discussed heat generation more than a few times, and I think there is agreement that larger capacity packs generate less heat since the pack current is divided up proportional to the pack parallelism. It works out that a 62 kWh pack that is ~ 1.5x larger capacity than a 40 kWh pack will generate ~ 1/2 the heat for the same power **.
The trade-off is in heat dissipation, presumed worse in tightly packed cases but no where as easy to calculate or model. Some empiric testing using e.g the EPA cycle, 40 mile a day, and at a couple ambient temperatures would be informative.
