Current test bench HVLR

voltagePLC-controlledfor electric vehicles

Bosch Engineering’s High-Voltage Lab Rig (HVLR) offers a fast, efficient and, above all, safe solution for testing the electric vehicle power electronics of the drive in the development lab. The HV test system integrates a high-voltage power supply and electronic safety functions for the circuit of the component under test in a compact 19-inch test equipment cabinet. Many of the tests on the power electronics of electric vehicles can therefore be shifted from the test bench to the high-voltage laboratory. This frees up valuable bench capacity for other testing and validation tasks, thereby reducing development time and costs. Thanks to its modular design, the HV test system can be flexibly adapted to individual customer requirements. For example, different voltage levels of up to 1,200 volts as well as different communication interfaces can be selected. Functions - Safe switching and monitoring of high-voltage up to 1,200 Volt / 200 Ampere - Isolation and operation monitoring - HV interlock - Safety PLC - Precharge and active fast discharge function - Emergency shut-off - Touchscreen or external monitor as central operating and display unit - Remote controllability - Integration into test automation  Modular design
