BQ4050: Battery Management Studio参数什么意思

Part Number: BQ4050


有人可以解释一下以下几项的详细意思吗,有举例就最好啦。

AOLD—Overload in Discharge   放电中的过载(什么意思)

       Latch Limit; Counter Dec Delay; Recovery; Reset; Threshold(各项什么意思,阈值单位是什么)

ASCC—Short Circuit In Charge 充电中短路

      Threshold 16进制表示单位是什么?

PTO—Precharge mode Time Out 预充超时

   Charge Threshold; Suspend Threshold; Delay; Reset(各项指的是什么)

OC—Overcharge(什么意思,单位为什么是mAH?)

CHGV—ChargingVoltage 充电时的电压?(什么意思,充电时电压不是一直在变吗)

    Threshold阈值; Delay延时; Recovery恢复 (各项指的是什么)

HGC—ChargingCurrent 充电时的电流?(什么意思)

  • 您好,AOLD基于硬件的过载放电保护, Latch Limit计数器跳闸阈值,Counter Dec Delay: Overload latch counter decrement delay; Recovery: AOLD保护恢复时间。

    Reset: : AOLD latch 重置时间。Threshold设置了保护延迟时间和阀值。对应TRM 15.1 Overload in Discharge Protection (AOLD)

    ASCC—Short Circuit In Charge:对应TRM  15.2 Short Circuit in Charge (ASCC)表格中的十六进制对应的电压单位mV除以Rsense的阻值,就是ASCC的短路电流值。

    PTO

     Charge Threshold: 预充电超时电流阈值; Suspend Threshold:  Precharge Timeout Suspend Threshold; Delay: 预充电时间;Reset:预充电超时重置阈值

    OC—Overcharge: 电池组充电超过FullChargeCapacity()OC的阀值就是overcharge,可以防止继续充电。

    CHGV— OverChargingVoltage() Protection,详细请参考TRM 2.17 OverChargingVoltage() Protection

    CHGC-----OverChargingCurrent() Protection, 详细介绍请参考TRM 2.18 OverChargingCurrent() Protection
