So I have made a simulation about heat generation in 12 cells 18650 battery pack. Material that I use is nickel(from material data base) both of busbar, tab, and cell. The connection of the battery is series. I use 1 c-rate and Time step size is 60 s. with NO. of time steps is 30.

The result is this picture below
