Connector Selection and Technical Requirements for New Energy Vehicles - Guide
New energy vehicles (NEV), in electric and hybrid vehicles, connectors play a critical role for power transmission, signal transmission and reliable connection.
Because working conditions are harsh, correct selection determines system reliability and lifetime.
5 Critical Technical Criteria:
1. Current and Voltage Values
Nominal values must be suitable for the system. In high voltage systems (400-800V) isolation and safety standards (CAT III, 3000V AC) are mandatory.
2. Temperature Resistance
Battery and power electronics environment varies in -40°C / +125°C range. Contact resistance (<0.5mΩ) and thermal cycle durability (1000+ cycles) should be evaluated.
3. Vibration and Mechanical Durability
For vehicle vibrations, locking mechanism (secondary lock + CPA), contact continuity, ISO 16750-3 vibration standard, 50G shock resistance are critical.
4. Environmental Protection
For humidity, dust, water IP protection: IP67 / IP6K9K, sealing, UV, salt spray and chemical resistance.
5. Material and Contact Performance
Contact: Silver-plated copper alloy, plating type, PBT / PA66 halogen-free housing, 10 years / 200,000 km service life.
Application Areas:High voltage connection connectorsLow voltage signal connectors Battery connection systems Compact automotive module connectors
Important Note: Selection should not be made only by physical size; it should be made according to manufacturer technical documents, IEC 62196, LV214, USCAR-2 standards and application requirements.
