LiPo battery charging efficiency
Jardar last edited by
We are looking to have a system where we use the LiPo battery as a emergency/ups type of powersource and as a capacitor bank for high currents draw during network (LTE) connects.. The main power will be delivered from a larger battery, but we are still limmited in battery.
So my questions is about how to optimize powerconsumption with LiPo and charger:
- What efficiency can we expect from the built-in charger (PySense board)
- Are there other circuits that are more efficient?
- What is the best way to implement charging with respect to powersaving (for example only carge when below 50% and charge to 85% instead of 100%)
- If so are there circuits that do this or does it have to be controlled by software in some way?

It's not really possible to give one efficiency figure for the built-in charger because of the many modes and dynamic operation. For full details I refer you to the datasheet of the charger chip used, the BQ24040
