Quality is measurable

High-voltage test station

HV test station for the safe commissioning of parts / components for charging and inverter technologies in the automotive sector of the future.

The rapid development of “PHEVs, MHEVs, BEVs” in electromobility brings, in addition to increasing challenges for measurement technology and ever higher requirements for data acquisition, a problem that has often been underestimated until now: the safety and protection of people when working on the high-voltage or high-current components or control units of e-mobility (e.g. chargers, converters).

Our safety concept closes this gap. Our specially adapted basic concept, consisting of various safety components, helps every technician or developer to carry out individual tests economically and ecologically safe for people and the environment.

These include:

  • Emergency shutdown control via a safety PLC (DIN-VDE)
  • Emergency stop circuit shutdowns according to the requirements of DIN-VDE
  • Protective hood system incl. interlocking (protection by distance and cover)
  • Monitoring of all system accesses (tamper protection)
  • Active limit value monitoring for voltages > 60V
  • Discharge concepts of residual voltage on active components
  • Mains failure monitoring incl. logging
  • Mains parallel operation of generation plants and a regeneration concept of reactive powers
  • Island operation
  • Active insulation monitoring
  • Active early fire detection system with optional active emergency extinguishing
  • Free selectable test run (PLC and VPS)
  • Access authorization and operating mode selection
  • Independent system acceptance by TÜV-SÜD
  • Adapted performance level selection according to customer requirements
  • Remote maintenance connection (worldwide – WAN)
  • Characteristic values voltage range: DC up to 1000V
  • Characteristic values voltage range: AC up to 400V
  • Characteristics power range (source dependence): 50kW / 100kW / 150kW / 200kW / 250kW

Extinguishing device demonstration video

Early fire detection and extinguishing technology provide the earliest possible detection in an emergency and also extinguish the fire in an emergency.

The early fire detection system has a highly sensitive smoke detection system that actively draws in and monitors the air from the test room. Feedback to the system is provided in several stages, so that the test object is de-energized even if there is only a small amount of smoke.

In the event that smoke development increases despite shutdown, first the emergency shutdown and then also the extinguishing device are activated in a further stage. The early fire detection system is battery-supported and can complete the extinguishing process. It complies with the DIN EN 54-20 standard.

In the video, a fire is simulated in the test room. The steadily increasing density of smoke triggers first stage 1 and then the extinguishing device. From different camera perspectives, it is shown how the extinguishing gas flows into the test room and extracts the heat from the fire, thus extinguishing it. The extinguishing gas leaves no residue on the test specimen.
