Battery Model Requirements

This document describes the implementation and requirements of the Battery and SOC Model.

Requirements

Inputs

• Battery Data
• Car's voltage + current draw + pack temperature + module voltage

Outputs

• State of charge estimate (% energy remaining)
• Energy remaining (Wh)

Nice to haves

• Integrate Driver Display (need firmware changes for this)
• Have a telemetry integration (individual cell voltages)
• An understanding of how much "energy" is left in the pack 
• Predicting range at different speeds (especially given modeled velocity)
• Good visuals 
• Historical data storing 
  • Individual cell voltages
• Cool displays + firmware integration 
• A reasonable smoothing of our SOC
• Tell the driver to limit motor current at low SOCs

Interface

• For first go, a CLI python model
  • Give me some good comments so I understand because I have a small brain
• Be able to see it on Driver Display
• See it on Telemetry
• Be able to query it somehow to get the amount of energy the car has left + the historical data 

Testing

• The actual testing to get the data
• Unit test all your functions
• At least one full-integration
