  • hi taohu,

    CYCT is the cycle count since a full reset. A full reset clears this register. Each count indicates a cumulative
    discharge equal to the Design Capacity (256 * ILMD). The host system has read-only access to this register pair.

    只有在累计的放电电量达到Design Capacity才会+1,

    您描述的实验过程没有看明白。可以描述一下您充放电电流大小,以及持续时间么? design capacity是多少?ILMD设定为多少?
