你好;
我想了解下BQ40Z80内部VC1-VC6单节电压采样流程;是同时采样6节电压还是按顺序每节电压
数据表里只说了1秒的间隔;
8.3.12 Voltage
The BQ40Z80 updates the individual series cell voltages at a 1-second interval. The internal ADC of the
BQ40Z80 measures the voltage, and scales and calibrates it appropriately. This data is also used to calculate
the impedance of the cell for the Impedance Track gas gauging.
IC自动进行电压采样,无需用户干预。每个电池组的电压也是按顺序采集的,但电压变化是渐进的锂化学变化,这意味着采样速度不需要很高,除非它们接近电压曲线的末端,但算法也因此提高了采样速度。
