请教:使用BQ34z100-G1做放电测试,大电流情况下SOC突变为0%

您好,如题所述,在大电流放电时BQ34的SOC会突变为0,每次测试都是放出10%左右的电量后突变为0,电量变为0之后,手动复位BQ34后能够恢复正常电量,或者静置一会也会自动恢复正常电量;

Chemical ID是对的,也做了充放电的学习过程,使用的.srec文件之前一直再使用,没有遇见过这个问题,现在重新做了BMS板,使用同一款电芯,在大电流放电测试中出现了这个问题。

放电过程中Log:

Gavin Xu1:

谁知道这个问题怎么解吗

,

Star Xu:

您好,已经在咨询这个问题,暂时还没得到回复。

,

Gavin Xu1:

好的,非常感谢

,

Star Xu:

您好,较大的放电电流会给电池的输出电压带来较大的I * R下降,如果放电电流足够大,则I * R的下降将足以将电池的输出电压下拉至EDV,这将迫使 RM设为0。我认为这是放电电流非常大导致的正常现象。

,

Gavin Xu1:

谢谢您的答复。放电测试电池电压RM突变为0时,电压为22.34V,6S电池,这个电压没有达到Cell terminate voltage(3000)值,怎么会迫使RM为0,还需要什么条件触发这个自动RM为0吗

,

Star Xu:

您好,建议您确认放电是RM突变为0时实际量测电芯电压是多少。
