bq27441 relax mode疑问

hi, TI大师们

 昨天已经开始调试bq27441了，bq27441spec中只提到normal mode -> sleep mode->hibernate mode，并没有看到relax mode。

请教relax mode是如何进入的？静置电池期间自己进入吗？调试过程中，opconfig中的SLEEP要设置为1吗？

谢谢！

    • relax，指的是电池充电完成或放电结束之后的relax时间，让电压进入平稳的状态

    Relax是指电流小于quit current是的状态，relax状态是相对于充电模式和放电模式而言的。详情可参考TRM里的描述，如下。Opconfig中的SLEEP bit是要配置允不允许芯片进入sleep模式。

    Charge mode is exited and relaxation mode is entered when EffectiveCurrent() goes below the quit
    current threshold for the number of seconds specified in Charge Relax Time (default 60 s). Discharge
    mode is entered when EffectiveCurrent() goes below the discharge current threshold for Quit Relax Time
    (default 1 s). Discharge mode is exited and relaxation mode is entered when EffectiveCurrent() goes
    above negative quit current threshold for Dsg Relax Time (default 60 s). Charge mode is entered when
    EffectiveCurrent() goes above the charge current threshold for Charge Relax Time (default 60 s).
