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:
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 empirical model
What are the aero losses? → Get data & build an empirical model
We need a working speedometer/telemetry, 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 sunshine?
How much of it do we pick up?
When driving?
With array normalization?
Motor efficiency ???
Battery loading efficiency ??? → Ask Micah Black
SOC ??? Karl ???
