I need to make an active cell Balancer using STM32 to balance Supercapacitors in following configuration: 5 capacitors are in series and every capacitor is attached with 1 another capacitor in parallel.
The rating of a Supercapacitor is 400F, 2.5V.
Here I've attached schematics that I thought of Drain of MOSFET connected to positive terminal of Supercapacitor configuration and Source to the balancing capacitor. Then Drain of other MOSFET to other side of balancing capacitor and Source to the negative terminal of below Supercapacitor. Similar connections followed for other Supercapacitors too. What do you think? Will this work?
Also for voltage reading of these Supercapacitors, I will be using ADC channel of SMT-32. The MOSFETs can be IRFZ44N. Furthermore Gate's can be connected to the output of Driver IC TC4422 (taking input from GPIO Input pins of stm32).
For activation logic of stm32, I am thinking of Voltage threshold based that it continuously monitors the voltage of each Supercapacitors. As far as burning of MOSFETS goes, I can use current limiting resistors to prevent risks, heat sinks can be thought of too.
I'm not sure if this idea will work so need help. Appreciated!
