Hello Team,
We are working on a one project, In that we are Charging our battery through BQ24650 charge controller.
We are planning to charge our battery through solar panel and USB. (Solar panel specification - 6V 1000mA)
We are facing listed below issue for reference find attached schematic.
1. Some time charging is working or sometime charging is not working, means charger only provide supply to main system not to battery.
2. Some times we got 1.2V MMPT at PIN 2 of charge controller.
3. Can we put one Boost converter before charge controller? (junction at USB connector and Solar panel), so the fix 1.2V MPPT is generate.
4. Kindly review the below schematic and give your valuable suggestion on this design
Thanks & Regards,
Mitul Tank
