BQ40Z50-R1: cell temperature model计算问题

Part Number: BQ40Z50-R1
Other Parts Discussed in Thread: BQ40Z50

1.我已经有了 bq40z50计算coeff calculator ,并且计算了 47k b值3435 ntc的coeff 参数。现在出现的问题是,当我校准了目前的环境温度23度时,当温度升高到32°时,电量计芯片中显示的问题是37℃。

2.现在我想问问 coeff a1 a2 a3 a4 a5 ,coeff b1 b2 b3 b4这几个参数的具体意思,这样我自己可以对这些参数进行细微的调整,以使温度更准确。
