Advantages

High voltage, high current, and high pressure performance

EP Icon 1
Using glass, rubber, and ceramic as insulation materials enables optimal electric insulation – even under severe environmental conditions. SCHOTT’s unique rubber insulation design provides the dual benefit of further enhancing the product’s electrical insulation properties while also preventing harmful condensation. SCHOTT offers e-Compressor Terminal designs that can support various refrigerants, including R134a, R1234y, and R744 (CO2) – which require high pressure resistance.
 
  • High voltage capability: 800 V (required for quick charging technology)
  • High current capability: 30 A ~ 150 A (required for 48V technology)
  • High pressure resistance: 20 MPa (required for CO2 refrigerants)

Superior reliability

What is an e-compressor?

Electric compressors, or e-compressors, are widely used in environmentally friendly vehicles to support the operation of the air conditioning system for optimal passenger comfort. Electric and hybrid electric vehicles are equipped with battery-powered compressors – unlike diesel or petrol-powered counterparts with an internal combustion engine that use belt-driven compressors. To work reliably and efficiently, these electric compressors must be hermetically sealed and function with their own motor inside. 

Why is the quality of e-Compressor Terminals so important?

E-Compressor Terminals are important components of electric compressors, and must be designed and manufactured carefully for optimal performance. An e-Compressor Terminal enables the transfer of large amounts of energy from the battery to the air conditioning compressor, and at the same time must remain reliably gas-tight to prevent refrigerant leakage. This is not an easy task, as electric compressors have very high performance and durability requirements while also being subjected to harsh environmental conditions. These include high pressure, high humidity and vibration. Compressor terminals must be able to withstand such adverse conditions without issue. Highly controlled and precise processes are necessary to provide long-term reliable gas-tightness.Moreover, the compressor terminals must deliver extremely high insulation resistance and high voltage capabilities to support future quick-charging technology developments. High current capabilities are also essential to enable upcoming 48V electrical systems.
