Goal: Give our driver an optimal driving profile.

What do we need?

  • Car Model

    • Energy Generation
      • Solar energy
      • Energy being absorbed by the solar cells
      • Regen braking
    • Energy Consumption
      • Dynamics model
        • Aerodynamic losses
        • Elevation changes
        • Friction
      • Auxillary Stuff
        • Motor losses
        • LV losses
        • Battery efficiency

  • Environment Model

    • Route
    • Wind
    • Weather
    • Contingency Planning

  • State of Charge

    • Bigly Important

  • Optimization

    • Take car model + requirements + route + meteo data => driving profile
    • Timing (start + stop)
    • Speed requirement
    • Lights + Turns
    • City driving
    • Track driving
    • Smoothing of drive profile
    • Charging times
    • Strategic stops
    • Speed limits
    • Stops & turns
    • Traffic dumping

Deadlines:

  • Track Day - Sunday

  • Track Day - June 9th

  • Track Day - June 22nd

  • Questions to answer before FSGP: 
  1. How many kwh do we have in the pack?  →  Measure it!
  2. What is the weight of the car?  →  We know that!
  3. What is the rolling resistance of the tires?  →  Get data & build empirical model
  4. What are the aero losses?  →  Get data & build an empirical model
    • We need a working speedometer/telemetry, anemometer, and measuring of speed vs. time.
  5. How much energy does the car lose being alive?  →  Ask Taiping (hopefully he figures it out!)
  6. How much solar energy do we get?
    • How much energy does the sunshine?
    • How much of it do we pick up?
    • When driving?
    • With array normalization?
  7. Motor efficiency ???
  8. Battery loading efficiency ???  →  Ask Micah Black
  9. SOC ???  Karl ???

FSGP - July 2019

...

AUGUST

  •  Strategy repository - Github action for testing
  •  Update Jira board with incoming tickets
  •  Update Confluence with data storage, strategy clients, overview of strategy repo
  •  Establish style guide and onboarding guides
  •  Finalize plans for strategy visualizations (and how they interact with other Midnight Sun systems)
  •  Look for “missing feature” - any functionality that we want that hasn’t been added as a ticket; any models that we will need that haven’t been outlined or planned
  •  Outline how our two efficiency profiles will exist within repo; switching between coils frequency
  •  Strategy models on Raspberry Pi feasibility

SEPTEMBER

  •  Welcome new team members! Onboarding
  •  Update mobile app plans based on infotainment progress
  •  Update visualization plans based on firmware progress
  •  Dynamics data smoothing complete
  •  Update SOC models for missing features (eg. distance remaining, time remaining)
  •  Determine how to analyze race loop decision
  •  Determine how we want to consider weather (and consequently, how we want to test solar panels)

OCTOBER

  •  Develop testing plan for our visualizations and mobile app
  •  Research tire (Ecopia with Ologic) wear effect on rolling resistance and determine if negligible; how we want to test this conclusion
  •  Establish what the testing plan for SOC/battery box model will look like

NOVEMBER

  •  SOC/battery box should be complete; have model complete and ready for testing as well
  •  Testing for battery box model
  •  Complete refactoring of car optimization model (both coils)

DECEMBER

  •  Establish April testing plan for rolling resistance, drag coefficient

2021+

  •  Testing
  •  Leftover tasks from Fall
  •  More TBD
