Specialising in the manufacture of various types of inductors, choke coils and linear filters.

AIT1000-SG has a high gain and measurement accuracy in the full bandwidth range, due totheapplicationof the multi-point zero-flux technology system and high-frequency ripple sensing channel ontopof currentlyexisting DC sensor technology. The multi-point zero-flux technology system secures the high accuracy by utilizing thetechnologycombination of exciting magnetic flux closed-loop control, self-excited magnetic fluxgateandmulti-closed-loop control that realizes the closed-loop control between excitation magnetic fluxandAC/DCmagnetic flux generated by primary current, while the high-frequency ripple sensing channel allowsthesensor to have the high performance over the full bandwidth range.

BMS500 fluxgate transducer is made of an excitation magnetic ring and a control circuit. Under normal
conditions, the control circuit generates a fixed excitation current frequency to alternately place the magnetic
core at the maximum saturation point. When the measured current flows, the primary current is measured by
detecting the symmetry of the saturation point.

The BMS series is suitable for battery monitoring systems that require high accuracy and low offset.
It can realize the isolation measurement between the primary current (high voltage) and the secondary
current (12V system).

PHEV and EV system may use different technologies of batteries. One very important parameter that mayinfluence the stability of the SOC is the temperature. The battery temperature affects vehicle performance, reliability, safety and lift-cycle cost. The BMS500 series is qualified between -40 to 85 but the transducer shows a better accuracyinarestricted temperature range in order to deliver a very accuracy current measurement.
