Safely Measuring and Mastering High-Voltage Power Distribution

Mastering high-voltage systems starts with transparency.
In modern electric vehicles, reliable current, voltage, and isolation measurement is far more than just a measurement value. It is the foundation for functional safety, robust protection concepts, and traceable fault diagnosis in the high-voltage system.

Only by continuously and precisely measuring currents, voltages, and insulation conditions can charging and discharging processes be safely designed, protective functions be effectively implemented, and high-voltage architectures be reliably managed—even under dynamic load conditions.

Reduce complexity – without sacrificing safety.
Modern EV architectures benefit from consolidating relevant measurement data into clearly defined system modules. This reduces external components, interfaces, and wiring effort—while simplifying integration, diagnostics, and the scalability of modular platforms.

Isabellenhütte supports developers right where it matters.
With its many years of experience in precision measurement technology for high-voltage applications, Isabellenhütte offers sensor concepts that combine current, voltage, and insulation monitoring in a single component – developed to
ISO 26262, with insulation fault detection in under 5 seconds and an operating range from −40 °C to +125 °C. The result: reliable measurement data across temperature and lifetime, a dependable foundation for functional safety concepts and modern battery management systems.

One sensor, one interface – and plenty of real-world questions.
A sensor provides current, voltage, and insulation data via a single CAN interface—that sounds simple, but when it comes to designing commercial vehicles, construction machinery, and stationary storage systems, it raises precisely the questions that determine functional safety: What are the limits of integration? How do individual measurement values translate into a safe protection concept? And what does that mean specifically for your next HV architecture?

We’ll answer exactly these questions in Isabellenhütte’s free webinar—with real-world examples from the truck and off-highway sectors and the next generation of current, voltage, and insulation monitoring.
