The AHBC-CAN500/24V power sensor is a high-precision DC current sensor primarily installed on battery busbars to monitor charging and discharging currents. Utilizing fluxgate technology, it offers high precision and low hysteresis. With a zerooffset current less than 10mA, it maintains low zero offset and high accuracy even after exposure to large currents up to 1000A. This sensor is ideal for power battery monitoring, high-precision current measurement, and battery management systems, meeting the SOC estimation accuracy requirement of less than 10% as per national standard QCT897-2011. All functionalities comply with automotive-grade standards.
