簡介

     AHBC-CANB電量傳感器為一高精(jing)度(du)直(zhi)流(liu)(liu)電(dian)(dian)(dian)流(liu)(liu)傳感器，主要安裝于(yu)電(dian)(dian)(dian)池組母(mu)排，用(yong)于(yu)監(jian)測(ce)(ce)充放電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu)。AHBC-CANB采(cai)用(yong)磁通(tong)(tong)門(men)技術，具(ju)有高精(jing)度(du)，低磁滯等優(you)點(dian)(dian)。零(ling)(ling)點(dian)(dian)偏置電(dian)(dian)(dian)流(liu)(liu)小于(yu)10mA,由于(yu)采(cai)用(yong)磁通(tong)(tong)門(men)原理(li)，無(wu)磁滯影響，在(zai)1000A大電(dian)(dian)(dian)流(liu)(liu)沖擊后仍能保持低零(ling)(ling)偏，高精(jing)度(du)特性。因此特別(bie)適用(yong)于(yu)動力電(dian)(dian)(dian)池電(dian)(dian)(dian)量(liang)監(jian)測(ce)(ce)，高精(jing)度(du)電(dian)(dian)(dian)流(liu)(liu)監(jian)測(ce)(ce)等應用(yong)場合。電(dian)(dian)(dian)池電(dian)(dian)(dian)流(liu)(liu)監(jian)測(ce)(ce)及(ji)管理(li)系統。

磁(ci)通門原理在高精度測量(liang)領域具有(you)絕對的技(ji)術優勢(shi)，采用激勵磁(ci)場持續振蕩，可等效(xiao)于消(xiao)磁(ci)磁(ci)場，進(jin)而使磁(ci)滯降到低。

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電量傳感器滿足該精度要(yao)求(qiu)，并且具有更小的磁(ci)滯及更小的零點偏(pian)移。
