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
