Hi,
We are looking for a mobile single cell LiPo gas gauge that should work in a high dynamic current system. I was checking bqJunior product, but I'm not sure if it will work according to our requirements:
- single cell LiPo; 400mAh; not changeable
- motor controller PWM controlled
- short (300ms) 3..4C current phases 40 times a day
- best would be remaining charge in % readable
- small component outlines
- micro controller in system that could adjust read result
We know aging could be quite fast. But, if I read data sheet I read something on a integration time for current (sensor voltage) of 5s. Would this integration cycle time consider these short current peaks (PWM with changing duty cycles)? And, what about aging? Is it possible to adjust aging parameter? How many charging cycles it will last until we can read a good remaining capacity? What would be the reading until the self calibration higher or lower capacity than available (lower would be acceptable)? Will it work at all? Are there different devices that would match much better for our demands?
Thanks
Uwe
