簡介

    AHBC-CANB電量傳感器為一高(gao)精(jing)度直流(liu)電(dian)流(liu)傳感器，主要安裝于(yu)電(dian)池組母排，用(yong)于(yu)監(jian)測充放電(dian)電(dian)流(liu)。AHBC-CANB采用(yong)磁(ci)通門技術，具有(you)高(gao)精(jing)度，低磁(ci)滯等優點。零點偏置電(dian)流(liu)小于(yu)10mA,由(you)于(yu)采用(yong)磁(ci)通門原理(li)，無磁(ci)滯影(ying)響，在(zai)1000A大電(dian)流(liu)沖擊后仍能保持(chi)低零偏，高(gao)精(jing)度特(te)性。因此特(te)別(bie)適用(yong)于(yu)動力電(dian)池電(dian)量監(jian)測，高(gao)精(jing)度電(dian)流(liu)監(jian)測等應用(yong)場合。電(dian)池電(dian)流(liu)監(jian)測及管理(li)系統。

磁(ci)通門原(yuan)理在高精度測量領(ling)域具有(you)絕(jue)對的技術優勢，采用激勵磁(ci)場持續振蕩，可等效于(yu)消磁(ci)磁(ci)場，進而使磁(ci)滯(zhi)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電量傳感器滿足該精度要求，并(bing)且具(ju)有更小的磁滯及更小的零點偏移。
