Cooling System Optimization
...
Decide whether we would rather crank up the fans or run the car at a lower speed (and rely more on passive cooling)? idrk how the fans work rn lol
also need to run car to maintain a safe temperature for the battery pack (in addition to not drawing out too much power)
...
Optimizing the cooling system. If energy effects are negligible, we leave it out of scope of the team. However if requires relevant energy consumption, it becomes a SUN POWER issue.

Battery Performance
Testing the battery’s reception to solar energy and optimizing performance/monitoring performance. Kinda broad but can help answer questions regarding cell placement, cell traction, battery optimization etc.
Telemetry might focus on this topic or we might address in Coloumb Counting.
...
Over, under -voltage, current for each module. Send feedback to chase vehicle (could be part of telemetry)

Coulomb Counting for Capacity of battery
...
Will address the “How much energy left in the pack?” question.
We could have rate of capacity decrease indicator. The difference between what we are getting from the sun and energy we are using.

...
Critical
Metric to usage, input and energy. Explore rate of capacity decrease indicator.

Battery Module Testing
...
Discharge a module in a way similar to a full day of racing. Monitor temperature, current, voltage, and other important indicators
Can also test thermal performances specifically
possibly different cell configurations ← realized this may be more of a battery box specific thing
Prototype module being developed.
Figure out profile of a day of racing.
Simulate day of racing and collect statistics
Different cell configurations based on race results.

Battery Module Testing | Battery/Strategy Audits
| Dec. 2022 | Battery WIP to explore Micah’s work. (Check out Micha’s GitHub) Battery-led development. Strategy available to assist with any tasks. | |
Battery Monitoring Dashboard | Prototyping Phase
Initial Research
| Dec. 2022 | Strategy / ~ Battery | Strategy WIP, will generate “MENU” once term kicks off. |
Solar Array Testing | Battery Ownership
Re-convene with possible owner(s). | Dec. 2022 | Strategy / ~ Battery | Priority: Assign a Strategy member to lead. In-person BAY visit to figure out solar cart, measurement tools, logistics, battery involvements, etc. Optional requisite: MMPT functionality, test separately and then integrate Mimic a measurement this Winter to support the data collection plan. Measure every parameter. Angle, date, weather, temp. Expected solar energy vs received solar energy. |
Sunny Day | Complete Strategy ownership - will keep battery in the loop. | Dec. 2022 | Strategy | In-progress |
