Application Fields
-
Electric vehicle energy efficiency certification and driving range testingHigh-precision closed-loop current sensors are essential tools for EV performance testing and certification. On test benches, they provide millisecond-level accurate measurement of input and output currents for drive systems, battery packs, and high-voltage auxiliary systems.
This extreme accuracy is critical for evaluating motor, inverter, and drivetrain efficiency, verifying official range data, and optimizing vehicle energy management systems.
-
Battery testing and large-scale capacity formationDuring lithium battery capacity grading, lifecycle testing, and formation, high-precision closed-loop current sensors provide sub-millivolt-level current measurement accuracy.
In large-scale battery production lines, they ensure ultra-low drift control of charge and discharge energy for each cell. This exceptional measurement stability is essential for cell consistency, maximizing yield, and accurately classifying battery performance.
-
Electricity Measurement Standards and Testing Instrument CalibrationHigh-precision closed-loop current sensors typically use advanced fluxgate technology for near-zero flux compensation, achieving minimal residual magnetic error and excellent temperature stability.
They are widely applied in national or laboratory-grade power metrology standards, internal calibration circuits of high-precision power analyzers, and current sensor calibration setups for high-end electronic test equipment, serving as key components for accurate power measurement and maintaining metrology reference standards.
