Meetings:

TitleObjectivesDate
Drive States

Coming up with scenarios for the following events:

  • Acceleration
  • Braking
  • Parking
  • Idle
  • Cruise Control
  • Regenerative Braking
  • Faults: faults that can happen while driving, and how we're gonna handle them
Monday Nov 11
Car's Charging

Coming up with scenarios for the following events:

  • Solar
  • Regen
  • Off-grid
  • SoC

Car's Power States

Coming up with scenarios for the following events:

  • Power on: (already done)
  • Initiating pre-charge from aux mode.
  • Safe-state
  • Charging from grid
  • Charging from solar cells
  • Power off

Interiors

What we're going to show:


Debugging
  • Telemetry
  • GUI:
    • Battery:
      • Module states 
        • voltage
        • temperature
        • SoC
      • Relay states: open/closed
        • what they should be (?)
    • Motor state
    • Self-test:
      • LV current distribution

Power Consumption
  • Idle state: what's the minimum?
  • data:
    • Where is the power getting used? (possibly live charts, etc.)
      • All coming from power distribution's current measurements
      • BMS current sense
