Introduction The AHBC-CANB power sensor is a high-precision DC current sensor, which is mainly installed on the busbar of the battery pack to monitor the charging and discharging current. AHBC-CANB uses fluxgate technology, which has the advantages of high precision and low hysteresis. The zero-point bias current is less than 10mA. Due to the use of the fluxgate theory, there is no hysteresis effect, and it can still maintain low zero-bias and high-precision characteristics after 1000A high current impact. Therefore, it is especially suitable for power battery monitoring, high-precision current monitoring and other applications. Battery current monitoring and management system. The fluxgate theory has absolute technical advantages in the field of high-precision measurement. The continuous oscillation of the excitation magnetic field is equivalent to the degaussing magnetic field, thereby minimizing the hysteresis. Item 4.2.4 of the national standard QCT 897-2011 stipulates that the SOC estimation accuracy requirement is not larger than 10%. In order to ensure this accuracy, the charging and discharging monitoring accuracy needs to be better than 1%. In order to ensure high-precision SOC in both high-current and low-current situations, the full-scale accuracy of the sensor needs to be further improved to 0.3%. AHBC-CANB power sensor meets the accuracy requirements, and has smaller hysteresis and smaller zero offset.
