2022-2024 Power Gen Retrospective

For questions, contact:

• Leadership: Roy Mor, Andrew Yin

• MPPT: Matthew Yu, Roy Mor, Andrew Yin, Tienda Hwang

• All array members:

Things we did well:

• Array and commercial MPPT worked

  • Around 600 Watts max under cloudy conditions with old MPPTs

  • Drivetek MPPT (drivetek_MPPT_RaceV4_Manual (1)) - very old

Things we can improve

• Have working black bodies

  • Problem:

  • Solution:

• Have working custom MPPTs

  • Problem:

  • Solution:

• Have good backup commercial MPPTs

  • Problem:

  • Solution:

• If we do lamination in-house in the case that we don’t find a good encapsulation manufacturer, we should:

  • Problem:

  • Solution:

    • After researching and designing our new array, during the manufacturing phase, we should spend every workday for at least 2 hrs working on encapsulation. This can be: characterizing cells, cutting Teflon, soldering modules, testing modules, laminating, etc. Quick lamination guide: Lamination Checklist

• Have array be more integrated into the rest of the electrical systems

  • Problem: We don’t know other systems' projects and designs, and vice versa. This limits the amount of learning on our team. Knowing how the car’s components interact, especially the neighboring systems to array like BPS, can help us design better as well.

  • Solution:

    • Design reviews, code reviews, board reviews

    • Working at pickle

    • SoM architecture like the rest of the electrical systems

• Keep deadlines better for every member on power gen

  • Problem

  • Solution:

    • discuss deadlines and goals in 1:1s and in team meetings

• Make sure every member is doing a project that they want to do

  • Problem

  • Solution:
