If you disconnect you battery and your MPPT is at full load, and 4-phases have concentrated energy in toroidal coils, after you BMS disconnect battery, voltage spike from accumulated energy will destroy caps and FETs or IGBTs, also CC-CV algo is not good, because it take long time to charge battery with low current in CV mode, and hight voltage at cells will destroy your electrolyte and after few hundred cycles, battery will have lower capacity and high resistivity and will deterriorate even faster. BMS has to communicate with Charger/MPPT/Inverter, because if not, it is very hard to dissipate e.g. 100 A x 4.2 V, if one cell is bad and another 13 cells are at low voltage.
Nice Explanation. I got one question: Where did you get the figure from 06:58 and the equation Nu = 0.0059 Re^0.09238 * Pr^0.4 from? I can't find those in any literature. Can someone help?
The parallel circuit is for conduction through metal to metal contacts. You need to break down the total cm2 heat flux area to small small patches even while considering TIM. Feel free to send me your query in detail on knowingindetail@gmail.com
