DC charging

CCS

  • parts
    • CCS-socket e.g. Phoenix Contact ~EUR 800,-
    • input voltage monitor
    • power contactor (+125A disconnecting device) Tyco ~EUR 150,-
    • 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
      • lock-motor fault pin
      • CAN transceiver (BMS communication)
      • 6 GPIOs (current-monitoring?, voltage-monitoring?, temprature-monitoring?, power contactor-driver?, (contactor-monitoring?))
