High precision current sensor HMI-201

Battery Test

HMI-201 is used in power battery detection for real-time monitoring of charging and discharging currents, accurately calculating the state of charge (SOC) and state of health (SOH), ensuring overcurrent protection and balanced control; Its mA resolution can detect microcurrent leakage , and its high-frequency response supports fast charging dynamic current, pulse charging and discharging, and harmonic analysis. This series wide dynamic range covers static sleep to kA level high current scenarios. By combining temperature drift suppression and anti-interference design, it significantly improves battery safety, life prediction accuracy, and fast charging performance optimization. It is widely used in battery research and development, production line testing, and fault diagnosis in fields such as electric vehicles, energy storage systems, and drones.
