Other Parts Discussed in Thread: BQ24650
Hi,
I just have a few basic questions about how the BQ24650 Module works. First, I am a little confused about what the MPPT does. On the website it says the MPPT " automatically reduces charge current so the maximum power point is maintained for maximum efficiency". I am confused because I thought that the current is what is important in charging, not voltage (as long as you meet the minimum voltage value). So why would you lower the current to increase the voltage? Also it mentions that the charge controller uses MPPT for the current and voltage going into the controller and uses PWM to regulate the current and voltage coming out of the controller into the battery. Why does it matter the values of the current and voltage going into the controller...isnt the point to step down the voltage and increase the current and then use PWM to charge the battery?
I know these are a lot of questions, so any answers I can get would be greatly appreciated.
