Climatic chamber for HV batteries

Project Facts


2 years

Coordination planning

Test benches:

  • Climatic chamber with a vibration table for the oscillation loading of a HV battery with thermal overlapping
  • Installation in a large room in a possible association of further climate chambers

Technical assemblies:

  • Multiaxial vibration table (Table and plunger suitable for low temperatures)
  • Climate chamber from -40 to 90°C with two-layer insulating shell (1000° C resistant insulation as fire protection plus foam insulation layer)
  • Cooling water conditioning to cool the HV battery
  • HV source sink to load the HV battery
  • Water mist cooling system in a circulation compound (Cooling of the HV battery in the Thermal Runaway)
  • Fire detectors by aspirating smoke detector
  • Pressure relief and flue gas exhaust to the outside (natural, without fans)
  • Safety control (fail-safe control) of the safety matrix

SBI services in detail:

  • Development and realization of the concept of fire protection measures for the protection of a theme runaway of a HV-battery in the test bench (climate chamber) with specifications for all involved trades
  • Planning of the fail-safe control for realization of plant controls from the safety matrix
  • Functional testing of the safety functions according to the safety matrix with all trades
