Hi Guys,
I have a 13S li-ion pack which powers my BMS MCU (CY8C58LP) after proper regulation, I want to read the voltage of individual cells via the ADC. One method which I could think of was using appropriate voltage dividers to bring the voltages within analog sensitivity range for every individual cells. The second method may be to use a mosfet based mux to switch the VDDA and VSSA to each individuals cell +tive and -tive and then read using ADC, but I am not sure if this is possible or what kind of impact this will do if I switch the analog ground dynamically.
thanks
Sanjeev
