CCS

• prerequisites
  • explore V2G protocol
    • http://openv2g.sourceforge.net
    • http://openv2g.org
    • https://www.v2g-clarity.com/en/risev2g
  • discover BMS <> Charger CANbus conversation
    • BMS/Battery (e4v.eu )
    • onboard charger (ies-synergy.com)
  • develop BMS <> PCL communication

• parts
  • CCS-socket e.g. Phoenix Contact ~EUR 800,-
  • input voltage monitor
  • power contactor (+125A disconnecting device) Tyco ~EUR 150,-
  • current monitor
