Part Number: BQ4050
在使用BQ4050用作电池管理芯片时发现了一个问题
使用的DM配置在最后，使用了动态计算的EDV2，EDV1和EDV0，没有使用EDV平滑功能，CEDV参数是根据实际所用电池测试所得
假设overload current为10A，从RSOC=100%开始12A放电，那么在EDV2之前VDQ标志位都会保持置位，如果继续保持，那么到达EDV2后VDQ会被取消置位，这种情况下一切正常。
如果电流一如既往的保持8A，EDV2后FCC会被更新，这种情况下也一切正常。
那么如果在一开始使用12A放电，在EDV2之前一小段的时候把电流调整到8A，这时候RSOC会被保持在7%，一直持续8A放电，最终的结局是CUV，且这时候的RSOC还是7%；如果在最终再把电流提高到12A，那么VDQ会被取消置位，然后正常放电，不过由于在7%停了太久，最终还是可能出现CUV。
我想知道这种情况的发生原因和机制
