2024 Xiaomi SU7 OEM Salvaged Charging Port Harness Assembly - 800V High-Voltage Connector with Waterproofing & Thermal Management

Restore or upgrade your Xiaomi SU7’s charging infrastructure with this factory-original salvaged charging port harness assembly, engineered for seamless compatibility with the SU7’s 800V high-voltage platform. Recovered from decommissioned SU7 Max/Ultra prototypes, this harness replicates the OEM design with IP67-rated waterproofing, thermal management systems, and precision-welded connectors for reliable fast-charging performance.

Core Features & Benefits

1. High-Voltage Compatibility

   • 800V Platform Support: Optimized for Xiaomi’s SU7 Max/Ultra models, enabling 510 km range extension in 15 minutes (120 kW DC fast charging) 

     
     
     .

      

   • Dual-Layer Shielding: Reduces electromagnetic interference (EMI) and ensures stable communication between the battery management system (BMS) and charging station.

2. Robust Waterproof Design

   • IP67 Rating: Sealed connectors and silicone gaskets prevent water ingress during heavy rain or submersion (tested to 1m depth for 30 minutes) 

     
     
     .

      

   • Corrosion Resistance: Stainless steel terminals and fluoropolymer insulation withstand extreme temperatures (-40°C to +125°C).

3. Thermal Management

   • Heat-Shrink Tubing: Protects solder joints and connectors from thermal stress during high-current charging.

   • Cooling Channels: Integrated heat dissipation pathways reduce connector temperatures by 15–20°C under peak loads.

4. Plug-and-Play Installation

   • Pre-Calibrated Length: Maintains SU7’s factory wiring routing and gap tolerances (±1.0 mm).

   • CAN Bus Integration: Direct replacement for SU7’s charging control module with verified protocol compatibility.
