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 ???
