CCS

• prerequisites
  • explore V2G protocol
    • http://openv2g.sourceforge.net
    • http://openv2g.org
    • https://www.v2g-clarity.com/en/risev2g
  • discover BMS <> Charger CANbus conversation
  • develop BMS <> PCL communication

• parts

  • input voltage monitor
  • power contactor (125A disconnecting device)
  • current monitor
  • V2G in-vehicle-charge-controller e.g. EVAcharge SE ~EUR 750,-
    • ARM microcontroller
    • Linux OS
    • fully programmable
    • PWM duty cycle detection (CP low level communication)
    • switchable resistors (CP low level communication)
    • HomePlug Green PHY integration (PLC high level communication)
    • Proximity pilot signal input (PP)
    • lock-motor output
    • lock-motor end switch input
