2024-2026 Electromechanical Electrical SSR Notes

Data Aq:

New Sensors

• Steering Sensor (angle)

• Break Pedal Actuation Sensor (potentiometer - angle)

• Barometric sensor (downforce - mounted at rear of car), Humidity Sensor

  • possibly two sensors for pressure differential

Controls:

New features:

• Motor
  • 2 wheel drive → 2 motors!!
  • 1 pedal driving
• Cruise Control
  • On/off button on steering wheel
  • +/- buttons on steering wheel to increase/decrease cruising speed
    
    • fast control
• Interior Changes
  • Buttons on steering wheel - dashboard switches move from dashboard
    • ex blinkers
  • adjustable fan control - potentiometer
• Blindspot detection
  • distance sensor
• SOM Design
  • wiring constraints

Power Generation (Array):

Sensors

• Temp
• Irradiance
  • Wires to both
• Bigger cells → less cells → new wiring needed for the array

Power Systems:

Power board

• switch from current system to a system that can shut off non essential systems when pulling from supplemental battery to avoid excessive power draw

Fuses

• Fuses for each component for over current protection
• disconnect from power sources for safety

New module connection/new wiring for batteries to make it the whole system less sketchy

Module = 9 cells in bracket, nickel plate spot welds to connect batteries in each module

Battery Protection Systems:

Boards:

• Leader
• Peripherals/Minions
  • 3x
• Amperes (charge/discharge)
• Fan board
• switching to SOM design
