SRN-SRP电流问题

Other Parts Discussed in Thread: BQ76930

我是用2个BQ76930的AFE
电池是20S1P, 72V/65AH
Rsense是0.625 mohm

当我放电电流越大时, SRN-SRP量到的电流会变大
例如:

仪器放电10A, CC_HI/CC_LO读到的电压值去除以0.625 mohm得到的电流值为 10.3A
仪器放电30A, CC_HI/CC_LO读到的电压值去除以0.625 mohm得到的电流值为 31.9A
仪器放电50A, CC_HI/CC_LO读到的电压值去除以0.625 mohm得到的电流值为 53.5A
仪器放电70A, CC_HI/CC_LO读到的电压值去除以0.625 mohm得到的电流值为 75.1A

请问一下为什么会有这样的结果?

如果不正常, 该如何去避免这样的问题

Thanks
