  • created + cleaned up MSXV Electrical Mockup Connections google sheet

  • Hardware Board Enclosures review

    • harnessing sheaths

      • combine common wires (i.e. GND) and splice them OR keep each wire separate but in common “casings”

    • FRONT ENCLOSURE TO REAR/BATTERY/CANOPY

      • run from sides following chassis tubes

    • REAR/BATTERY TO CANOPY

      • wiring needs to not restrict opening of canopy

        • Proposed path: Rear → Front → Rear (on side of canopy) → canopy

      • REAR/BATTERY TO TAIL

        • most direct path

      • UPDATE 28/08/2023: battery box ports will likely be on top of the front of our enclosure and maybe one or so on the lid for the AFEs

  • TO-DO:

    • work on PD/BMS portion of MSXV Elec Connections Google Sheet

      • remember to spec out wire gauges + length estimations!

7/26/2023

  • looking into harnessing softwares

    • Siemens

    • Solidworks Electrical

    • Solidworks Mechanical (extruded-circle for wire)

    • possibly no wiring CAD

  • mock-up diagram finalization

  • MSXIV Excel Wiring Tracker

  • Wiring speccing

    • look into MSXIV Electrical VDR

  • Task Delegation

    • break down by HV, LV; between enclosures

    • new-member friendly: speccing components (connectors, wires)

      • digikey skills, decision matrices, etc.
