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
  • Aero losses
  • Elevation changes
  • Friction
  • Auxiliary stuff
  • Motor losses
  • LV losses
  • Battery efficiency
  • Environment Model
  • Route
  • Are we meteorologists?
  • Or are we just creating scenarios
  • Contingency planning
  • State of Charge
  • Bigly important
  • Optimization
  • Take car model + requirements + Course + 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

Overall strategy timeline:

Deadlines:

Track Day - Sunday

  • How many kwh do we have in the pack?
  • Measure it!
  • What is the weight of the car? We know that!
  • What is the rolling resistance of the tires?
  • Get data
  • Build an empirical model
  • What are the aero losses?
  • Get data
  • Build an empirical model
  • We need a working speedometer, anemometer, and measuring of speed vs time
  • How much energy does the car lose being alive? Ask Taiping (hopefully he figures it out!)
  • How much solar energy do we get?
  • How much energy does the sun shine?
  • How much of it do we pick up?
  • When driving?
  • With array normalization?
  • Motor efficiency ???
  • Battery loading efficiency??? Ask Micah Black
  • SOC??? Karl????

Track Day - June 9th

Track Day - June 22nd

FSGP - July 2019

ASC - July 2020AUGUST

  •  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 (tentatively Dash)
  •  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
