Dear TI support team,
I was wondering if TI had any information regarding the challenges of an application, in particular, a Lithium Iron Phosphate battery pack that isn't fully charged or fully discharged often.
I know that gauging this chemistry poses challenges because of it's flat discharge profile, and that a full charge and a full discharge need to be accomplished in order to establish the upper and lower points of a curve.
This is done prior to battery packs entering the field.
However, in the field we have seen applications where the pack doesn't always get a chance to receive a full charge or get fully discharged.
These conditions lead to the state of charge drifting.
Do you have any tips or recommendations to combat this challenge?
As far as I know, properly recharging the battery pack to full charge can help correct any state of charge errors.
In particular, setting the RSOC hold on so that the pack holds at 99% until a full charge condition is reached.
Is this correct?
Appreciate your expertise and insight on this subject.
Regards,
Kevin
