Fraunhofer Institute for Integrated Circuits IISOur expertise in current measurement includes both new and proven techniques: First and foremost is model-based current measurement, an innovative method that uses mathematical models and advanced algorithms to accurately measure current. This method is constantly evolving. In addition, we rely on established and robust methods such as the differential field principle, which uses the difference in magnetic fields for precise measurements, and the ring integral principle, which enables us to accurately measure currents by integrating the magnetic field along a path. This is how HallinPower® technology was created.

Applications: Focus on energy efficiency
In times of the energy transition and the more sustainable use of resources, the precise measurement of currents in automobiles, industrial plants and smart homes has become a major focus. HallinPower® technology offers a comprehensive range of flexible solutions for a wide variety of requirements. Both proven methods for current measurement and modern approaches can be implemented. They enable quick installation and commissioning without calibration as well as the simultaneous measurement of several currents. Accordingly, HallinPower® is suitable for the following applications, for example:
- Current sensors for power distribution systems
- Monitoring of energy-efficient systems
- Energy monitoring of photovoltaic systems with inverters
- Battery condition monitoring, e.g. of the internal resistance
- On-board power supply monitoring
- Start/stop support without shunt
- Charging infrastructure in electromobility
- High current measurement in electrolysis processes
