Nevera RIMAC Battery Module Details and Analysis

I found a cool picture released by RIMAC of the Nevera Battery Module. I have edited it with my own analysis:

◼️The Module packaging 📦 is very impressive with no space wasted by extra tick connectors

◼️The Nevera Battery uses cooling plates (already known). But what is New to me is that there are actually 2 cooling plates sandwiching 🥪 the cylindrical cells

◼️The cooling plates are much more complex than usual ones and seem to be formed around each individual cells, not sure if it for optimising the cooling ❄️ or for holding the cells (or both?). You also can observe how thin ↕️ is the cooling channel inside the plate

◼️The cooling pipe system seems extremely complex. I understand the plates cannot be only plugged in series because it would (1) slow down the cooling 🌡; and (2) create too much heterogeneity between modules 🥶🥵

◼️For a reason I cannot figure it out, each plate gets 3 in/out pipes: 1 normal output (or input?) and dual inputs (or outputs?) that are different between the top ⬆️ and the bottom plates ⬇️ on this image. It probably deals with the cooling complexity described above but if anyone has an explanation, feel free to comment

◼️In the Center of the plate, you can see the structure is different (flat with no cell-shaping) and if you pay attention you can see a sort of « guide » (🚧) at the near end of the module that seems to force the liquid 💧 inside the plate so the flow turns ↩️ only at the very end of the module to ensure the cooling everywhere

◼️At first I thought a cell 🔋 has been removed for display purpose but when you carefully look at the cooling plate, you can see black pins (⚫️) that go through the Module structure (from top to bottom). I believe it is for structural reason but please comment if you have any other assumption

◼️You also can see how the cells are grouped in parallel. I do not know if RIMAC uses its own solution for cell connection but it reminds me of the Mersen Infini Cells System
