Purpose of the Task Force 
The purpose of this task force is to enable the NACS proposals to move in an expedient standardization process and support the process through industry aligned system-level charging specifications and definitions. The task force may focus on the following topics as determined during a June 27 alignment call (in no particular order): 

  • Safety 
  • Repeatability by multiple vendors 
  • Completeness of specification, including: 
    • System architectures  
    • Behavioral models Adapter safety 
  • Plug & Charge 
  • V2X/ bidirectional 
  • Current capability 
  • Consistent implementation 
  • Interoperability & reliability 
  • AC/DC overlay functional safety 
    • AC only designation 
    • DC only designation 
    • Labeling (AC/DC) 
    • Consumer experience (AC/DC) 
  • Cable length, layout, port position on vehicle, power level identification 
  • Opeb specification 
  • 1000 V variant mechanical robustness/ liquid cooled version of cable 
  • Standards for suppliers 
  • Voltage and current ratings 
  • Water drainage management 
  • Installation angles 
  • Future of J1772 
  • Mac’s product lines/ sharing 
  • Thermal management at charge plug/ inlet interface/ Cooled vehicle inlet 
  • DIN 70121 and ISO 15118  
  • Max charge power  
  • Certification of EV/EVSE interoperability 
  • Testing & proof of reliability 
  • First proof of electromechanical interoperability testing 
  • Testival activities 
  • Retrofitting CCS/J1772 
  • Ensure 100% compatibility of NACS with IEC 61851-1 and IEC 61851-23, both for AC and DC charging 
  • Prioritization of activities (i.e., stage gates) 
  • Normative (door) NFC signal & trigger signal 
  • Categorize the areas of focus and launch subgroups/ tracks and establish leadership 

Stakeholders for the Task Force 
Automotive, EVSE manufacturers, EVSE hardware & software developers, charge point operators.
