簡介

     AHBC-CANB電量傳感器為一高(gao)精度(du)直(zhi)流(liu)電(dian)(dian)(dian)流(liu)傳(chuan)感器，主要安裝于(yu)電(dian)(dian)(dian)池組母排(pai)，用(yong)于(yu)監測充放電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)。AHBC-CANB采用(yong)磁(ci)通(tong)門(men)技術，具有高(gao)精度(du)，低磁(ci)滯等(deng)優點。零點偏(pian)(pian)置電(dian)(dian)(dian)流(liu)小于(yu)10mA,由于(yu)采用(yong)磁(ci)通(tong)門(men)原理，無磁(ci)滯影響，在1000A大(da)電(dian)(dian)(dian)流(liu)沖擊后仍能保(bao)持低零偏(pian)(pian)，高(gao)精度(du)特性。因此特別適用(yong)于(yu)動(dong)力電(dian)(dian)(dian)池電(dian)(dian)(dian)量(liang)監測，高(gao)精度(du)電(dian)(dian)(dian)流(liu)監測等(deng)應用(yong)場(chang)合。電(dian)(dian)(dian)池電(dian)(dian)(dian)流(liu)監測及(ji)管理系統(tong)。

磁通門原理在高精度測量領域具有絕(jue)對的技術優勢，采用(yong)激勵磁場(chang)持續振蕩，可等效于消磁磁場(chang)，進而(er)使(shi)磁滯降(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電量傳感器滿足該(gai)精度要求，并(bing)且具有更(geng)小的磁滯及(ji)更(geng)小的零點偏(pian)移。
