Conceptual Design Review (CDR)

Presented by: @Shawn Coutinho

High level block diagram

• [ ] Look into fuse current specifications and current draw of the system with consideration for derating
• [ ] Spec proper bus bar able to handle current
• [ ] Automotive relay ratings
  • [ ] Consider checking current draw
• [ ] Consider taking a look at the BlueBoat circuit diagram for initial high level diagrams
  • [ ] Helpful for illustrating harnesses
• [ ] Fuses in line with elements that are likely to fail (such as ahead of ESCs)
  • [ ] Consider a trade-off of where to place different fuses
• [ ] Connector choice should avoid exposed conductive elements that are providing power
• [ ] Fuse for the computer battery too
• [ ] Reverse polarity protections for battery plugin in addition to fuses
  • [ ] See common circuit diagrams (Google)
• [ ] Stupid-proofing ideas for screw terminals
• [ ] Common ground for the whole system
  • [ ] Avoid ground loops
