Modern systems Power supply for electric vehicles, hybrid vehicles, and stationary energy storage require a reliable and secure architecture for HV circuit distribution. For these tasks, RUBRUKS has developed a line high-voltage switching units, among which are models HPDU-600-iso и HVCU2-600-iso. They provide centralized connection of battery modules to high-voltage consumers and integrate key monitoring and protection functions.
The key functionality of these devices is to operate with voltages up to 1000 V, allowing them to be used as part of traction battery systems and high-voltage distribution networks. Both blocks feature built-in Insulation monitoring devices (IMD), which allow the detection of both symmetric and asymmetric faults on the «plus» and «minus» buses.
This integration makes the blocks not only a switching hub, but also part of High-voltage functional safety systems, meeting modern industry requirements (including ISO 26262).
From an engineering perspective, particular attention has been paid to reliability and protection:
Thus, RUBRUKS HPDU-600-iso and HVCU2-600-iso High-Voltage Switching Units represent reliable and technologically advanced solutions for building secure HV infrastructure. They are a full-fledged alternative to foreign counterparts and are optimally suited for use in electric vehicles, hybrid technology, and stationary power units, where high power density, connection reliability, and built-in protection mechanisms are required.
