Explore advanced techniques and challenges in current, voltage, and insulation monitoring. We'll discuss the principles of current measurement using shunt resistors with combined sensor modules and the impact of tolerances and temperature coefficients. Topics include rapid pyro fuse control (<100 µs) in automotive and energy storage systems, voltage measurement requirements and multi-stage insulation monitoring in commercial vehicle application to ensure safety and reliability.
Overview
As battery-powered systems continue to evolve toward higher power, faster charging, and increased safety requirements, precise measurement and reliable insulation monitoring become critical success factors. In this webinar, Isabellenhütte Heusler, a global leader in precision shunt and sensor technology, will share insights into how advanced measurement solutions enable safer and more efficient battery management systems.
We will start with a brief introduction to Isabellenhütte and its unique expertise in high-precision materials and sensor technologies. The session will then explore typical battery management system architectures, highlighting key requirements for current, voltage, and insulation monitoring.
Participants will gain a deeper understanding of current measurement challenges, including accuracy under dynamic load conditions, thermal stability, and functional safety demands, e.g. igniting a Pyro-Fuse. We will discuss how Isabellenhütte´s ability to manufacture custom-shaped shunt resistors or custom sensor solutions beside standard products with ultra-low temperature coefficients enables very fast and optimized system integration.
A key focus will be electrical safety and insulation monitoring, comparing passive and active monitoring concepts and their impact on system response times. Looking ahead, we will address future energy storage requirements, such as fast charging and rapid fault detection, including the role of pyro-fuse ignition within few 100 µs.
The webinar concludes with a presentation of IVT UIR sensor technology and real-world applications of the IVT 3 PRO with integrated IMD for truck PDUs and energy storage systems.
