Hi.
I want to build a backup power system with a lithium-ion battery that includes a charger.
My system consumes 1 A during operation. The system works about a few seconds and then enter a low power mode and thus save energy.
I made a conceptual image of the idea I have in mind of that system, please see the image at the following link:
The system consists of a Voltage Boost Converter circuit and Lithium-Ion Battery Charger circuit.
The Voltage Boost Converter circuit could work with input voltages from 2 volts to 10 volts and its output is 5 V.
When an external voltage of 5V is present, the battery is charged by the Lithium-Ion Battery Charger circuit.
When the external source of 5 V is removed from the system, the diode D (Schottky) allows the discharge of the battery and the system continues to provide 5V thanks to Voltage Boost Converter circuit.
Do you think the concept is correct?
Could there be a problem with that design?
Any ideas or suggestions are welcome.
Thanks
