簡介

     AHBC-CANB電量傳感器為(wei)一高精(jing)度(du)直流(liu)(liu)電(dian)(dian)(dian)流(liu)(liu)傳感器，主要(yao)安裝于(yu)電(dian)(dian)(dian)池組母排，用(yong)于(yu)監測(ce)(ce)充放電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu)。AHBC-CANB采用(yong)磁通門技(ji)術(shu)，具(ju)有高精(jing)度(du)，低磁滯(zhi)等(deng)(deng)優點。零點偏(pian)置電(dian)(dian)(dian)流(liu)(liu)小于(yu)10mA,由于(yu)采用(yong)磁通門原理，無磁滯(zhi)影響，在1000A大電(dian)(dian)(dian)流(liu)(liu)沖(chong)擊后仍能保(bao)持低零偏(pian)，高精(jing)度(du)特性。因此特別適用(yong)于(yu)動力電(dian)(dian)(dian)池電(dian)(dian)(dian)量監測(ce)(ce)，高精(jing)度(du)電(dian)(dian)(dian)流(liu)(liu)監測(ce)(ce)等(deng)(deng)應用(yong)場合。電(dian)(dian)(dian)池電(dian)(dian)(dian)流(liu)(liu)監測(ce)(ce)及(ji)管理系(xi)統。

磁(ci)(ci)通門(men)原理在(zai)高精度測(ce)量領域(yu)具有絕對的技術(shu)優勢，采(cai)用激(ji)勵磁(ci)(ci)場持續振蕩，可等效于消磁(ci)(ci)磁(ci)(ci)場，進而使磁(ci)(ci)滯降(jiang)到低(di)。

國標QCT 897-2011中第4.2.4條目規定SOC估算精度要求不大于10％ 。為保證該精度，充放電監測精度需優于1%，為保證大電流，小電流場合下均有高精度SOC，傳感器滿量程精度需盡一步提高至0.3%。AHBC-CANB電量傳感器滿足(zu)該精(jing)度要求，并且具有更(geng)小的(de)磁滯(zhi)及更(geng)小的(de)零點偏移(yi)。
