Product Overview & Dual-Mode Charging Pathway
The YDCHARGE NACS (SAE J3400) to CCS Combo 1 AC/DC Charging Adapter is developed for electric vehicle charging applications requiring compatibility between CCS Combo 1 vehicle inlets and NACS charging equipment. Supporting up to 80 A AC charging and 500 A continuous DC fast charging at up to 1,000 V DC, it provides a high-current cross-standard solution for EV accessory suppliers, fleet operators, charging solution providers, and OEM commercial projects.
1. Dual-Mode Power Architecture & Active MCU Control
Direct AC/DC Power Architecture
Supports both AC Level 1/Level 2 charging and high-power DC fast charging through a unified NACS to CCS1 interface structure. The internal power pathway provides direct electrical transmission without power conversion loss or voltage conversion overhead.
High-Current T2 Copper Busbars
Utilizes high-conductivity T2 copper conductors with silver-plated contact surfaces. The low-resistance contact architecture minimizes internal electrical resistance and heat generation during continuous 500 A DC high-load operation.
Integrated Active Control System
Unlike passive adapters, this model integrates an embedded MCU and PCB control module that manages interface safety logic:
- Maintains required charging communication pathways
- Monitors active charging session parameters
- Executes intelligent thermal protection protocols
2. Advanced Three-Point Thermal Monitoring System
Triple NTC Temperature Sensor Placement
Monitors thermal state at the NACS charger interface.
Monitors thermal state at the CCS1 vehicle inlet connection.
Monitors external housing surface temperature during operation.
Stage 1: Current Limitation
When elevated temperature is detected, the system triggers charging current throttling through vehicle and EVSE control responses to reduce thermal stress.
Stage 2: Thermal Shutdown
If temperatures continue rising and hit critical protection thresholds, the adapter interrupts the control signal to stop power transfer completely.
Stage 3: Thermal Recovery
Power transfer remains safely disabled until internal sensors confirm temperature levels have returned to specified reset conditions.
3. Environmental Sealing & Interoperability Scope
IP65 Weatherproof Enclosure
Constructed with a sealed engineering enclosure rated IP65 when mated. Protects internal electrical conductors and MCU hardware from dust exposure and high-pressure water spray during outdoor charging sessions.
Network & Platform Interoperability
Designed for seamless operation across NACS AC equipment, NACS DC fast chargers, and CCS Combo 1 electric vehicles. Final charging availability depends on vehicle software support, EVSE setup, and network authorization.
