A battery management system (BMS), in addition to many other functions, has to closely monitor voltage, current, and the temperature of battery cells and packs. Temperature measurement is important in preserving the operational characteristics of both the cells and the BMS itself, as well as optimizing the state of health (SOH) by preventing degradation.
In a VHDL-AMS design, the heat production fluxes created by several transistors, other semiconductor elements, as well as heating elements can be directly injected into thermal RC networks modeling the heatsinks of these elements, or simply the ambient environment.
What if the designer would like to combine the electrical effects on one side with the thermal effects on the other?
No SPICE model can be better than the real measurements performed on electronic components, which are sometimes patiently gathered over the course of weeks and years.
