2019 Strategy Plan

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 ???
