Even in the high-temperature environment of summer outdoor exposure and long-term continuous high-current charging, the connector will not have excessive temperature rise, melting of insulating materials or aging of terminals, effectively avoiding safety hazards such as short circuit and ignition caused by overheating of the charging connector. In terms of mechanical performance, the service life of the 80A fast charging connector's plug-in and pull-out cycle is more than 10,000 times. After long-term frequent plug-in and pull-out use in public charging stations, the plug-in accuracy and contact stability can still be maintained, and there will be no poor contact and current interruption caused by terminal wear and loose fit.

The structural design of the 80A fast charging connector is scientific and reasonable, adopting a multi-core integrated modular structure, including DC positive and negative power supply terminals, auxiliary power supply terminals, communication signal terminals, grounding protection terminals and temperature detection terminals. The power supply terminals are responsible for 80A high-current DC power transmission, adopting a thickened copper terminal structure with large contact area, which improves the current carrying capacity and heat dissipation efficiency.
