AHBC-CAN CAN communication Hall sensor

The AHBC-CAN500/24V power sensor is a high-precision DC current sensor primarily installed on battery rails to monitor charge and discharge currents. Featuring fluxgate technology, it offers high precision and low hysteresis. With a zero-offset current below 10mA, it maintains a low zero-offset and high accuracy even after loading with large currents up to 1000A. This sensor is ideal for power battery monitoring, high-precision current measurement, and battery management systems, and meets the SOC estimation accuracy requirement of less than 10% according to the national standard QCT897-2011. All functionalities comply with automotive standards.

  • Measurement: Direct current (DC)
  • Nominal measuring current: 500 A
  • Communication: CAN 2.0 interface
  • Accuracy: 0.2 % [Temperature drift < 50 ppm]
  • Perforation size: 23.7 mm
  • Power supply: +18 ~ +28 VDC
  • Application: Battery management system (BMS) for electric vehicles, battery distribution unit (BDU), high-voltage distribution unit (PDU), energy management for industrial lithium batteries, onshore emergency power supply
