Application Scenarios for The NACS Charging Port?

1> Passenger Electric Vehicles

Ultra-Fast Charging for Consumer EVs, Enable 10% -80% SOC in 9 minutes (350KW) for premium EVs with 800V/1000V battery systems.

- Supports bidirectional charging (V2X) for vehicle-to-home (V2H) and vehicle-to-grid (V2G) energy transfer.

- Technical Edge:

-1000V DC rating ensures compatibility with next-gen high-voltage architectures (e.g., Porsche Taycan, Lucid Air).

- Dual NTC sensors on DC+/DC- terminals prevent overheating during sustained 350A+ operation.

Urban Mobility & Fleet Vehicles
- Optimized for ride-hailing fleets requiring high-duty-cycle charging (50+ cycles/day).
- Compact design suits urban charging stations with space constraints.
- Durability:
- IP67/IP69K protection withstands frequent plug/unplug cycles in all weather conditions.
- Snap-in locking mechanism reduces maintenance costs vs. screw-type connectors.

2. Commercial & Heavy-Duty Vehicles
Electric Trucks & Logistics
-Scenario:
- Delivers 1C charging rates for 600kWh+ battery packs (e.g., Tesla Semi, Volvo VNR Electric).
- Liquid-cooled 350A+ configurations sustain continuous operation in long-haul trucking.
- Customization:
- Shielded high-voltage harnesses (up to 15m length) for trailer integration.
- Military-grade materials (Type 3R) resist road salt, dust, and vibration.
Public Transport (Buses, Shuttles)
- Scenario:
- Supports overnight depot charging at AC32A/DC150A for municipal bus fleets.
- CAN FD communication enables smart load balancing across multiple vehicles.
- Safety:
- UL94-V0 flame-retardant housingmeets transit safety regulations (e.g., NFPA 130).

3. Microgrid & Emergency Power
- Scenario:
- Critical for V2G-enabled microgrids providing backup power during outages.
- 12-24V electromagnetic lock ensures secure coupling in mission-critical applications.
