BQ25700A 充电电压设置16.8V,但实际测量出来只有16.72V,实际电池充满16.7

请问是否需要实际做补偿,谢谢

Star Xu:

这误差在范围内.电器性能表中有提到charge regulation voltage accuracy of +/- 0.5%

When termination condition is hit, there will be an artificial voltage drop across Rimp*Iterm which tricks IC into thinking battery is charged. This depends on your termination current setting and impedance of wires/trace. You can try lowering your termination current to reduce the effect of this extra voltage, so battery is charged more fully, but from your results this seems to be with expected range.
