The guys at Autoline Network have put a Tubecast together of the Model 3 teardown where they discuss the BMS, onboard controls, and of course, the battery
The cooling system was always going to be an engineering challenge, given their desire to pack as many cells into the space available. So they used thermally conductive silicone gloop to both stabilise the cells from vibration and to soak heat away from the cells towards a cooling plate top and bottom.
The wire-bonded busbars are consistent with their earlier battery designs, although a huge weight saving has been realised in not using the polycarbonate supporting plates.
I don't think they will be stopping the cells from getting very hot on occasion, but they will definitely work at getting the average cell temperature down. I look forward to more in-depth teardown!
