BQ76PL455A-Q1: Negative temperature perfermance is poor

Part Number: BQ76PL455A-Q1

Dear TI Experts

About BQ76PL455A-Q1,When testing negative temperature, some PL455A has great error. We have done the  cross-over experiments  , found that IC with large error is always large. 

We would like to know  whether the characteristic is poor when testing negative temperature?
