Requirements

module testing v1: a lot of learnings about assembly, module design, testing procedure

module testing v2: shits getting serious

mechanical design
fit check
boards | waiting on boardmounts CAD to be finished to make final CAD revisions of module top plate (only 3 modules will need the AFEs on top, the other 6 can be left)
taps
current sense
wiring
thermistors
busing
cells
fixturing (screws, inserts, etc)
module to module
fixturing??? We will need to find insulating bolts/fasteners for module to module connections. Unsure if Eric ordered them already or if they need to be ordered. This means busbars will need a revision as well to make it electrically insulated
module to enclosure
fixturing??? Nicole working on module to enclosure securing
electrical performance
busbar to cell
module to module
monitoring & bms

Overall, I think we should focus on getting the entire system rolling, rather than optimizing thermals, etc…

  1. BMS

    1. get mitch all the info he needs

  2. Motor Testing (since we can’t push modules with e-loads, lets just push it with the motor…)

    1. Motor controller

  3. Pack characterization

    1. coulomb counting

  4. Update documentation as we go

Kostubh’s Time Allocation

  • Module R&D completion oversight

    • All focus on Eric’s CAD

    • Down to redesign busing

    • Calcs

    • Oversight…

  • Coulomb Counting

  • Telemetry (Not really)

  • Anything else? How can I be most helpful

Onboarding

  • Focus on trial & error don't bombard kids with info, I think we do too much research

  • Design logs/documentation (helps the team and you)
