title05 November 2023 - Testing & Vallidation + Module Manufacturing

Production Module Testing (4.5.3)

  • keysight: not feasible too long

  • two paralle

possible solutions for worst case:

  • ask other people? not done yet

  • ask profs

  • maybe past documentation

  • ask teerstra

  • ask lab in waterloo

  • talk other design teams

  • ask prof for battery challenge

Current assessment of module manufacturing & testing

  • all modules to be completely manufactured: dec 8th

  • will have to check with testing the first module

  • do we have prototype module testing goals?

    • draw for 30min and check temperature

    • asc does not outline anything specific

Prototype module testing:

  • depends on what we say

    • will say it was first one made (of the production run)

  • documentation needed? no but yes (for future etc)

  • keep prototype deadline same on pvdr but aim for end of nov

  • continue to test for production

Pack & battery systems validation

  • different equipment?

    • either use motor or power resistors

    • have a completed plan before jan 2024 (check-in mid-dec)

Actionables:

  • module manufacturing timeline done for 06-11 (will check with donna)

  • working on on validation plan - check monday 05-11 and review (check with owen)

  • jenna will start prototype testing this week, feasibility test (check-in end of week)

    • just draw current 58.2 A and 3.6V with module

title05 November 2023 - Enclosure Manufacturing

why are baffles being redesigned?

  • bc safety wire

  • too much wire around the box

  • not checked

  • will not push to git, keep to safety wire

Design change

  • one extra cutout need for molex connector

  • air duct been designed?

    • cad changed for fan folders to accommodate for air duct (completed)

    • will be stuck with tape

    • once air duct connector cad done will check with jenna

Image Added

Machining

  • only a few extra inches to the order

  • jenna will assign to experienced machining people to get it done

3d prints

  • fan holders (problem with heat set)

    • two seem viable from prototype, will be used for module

  • Hydrophobic mesh for inlet will look into it now -shem will do

  • enclosure feet: petg

    • will might need to modify according to weld bead

    • can we print right now? yes can print, but might need to modify to fit bolts to chassis

    • air baffles and diagonal supports can print right now

Electrical integration

  • wires who will buy?

  • so far know:

    • can use hardware money (can check confluence page)

    • all connectors for wiring in and out of box

  • deliverable: have a list of everything in battery box in electrical that is not module in enclosure (for saturday working session 11-11) will confirm with jonathan/forest

    • fans, connectors, etc

jigs

  • crossbar is good

  • chassis is good

mdf

  • jenna will let nicole know when done to check

welding

  • what happens if it sucks?

    • if too small use 1/8 inch board

    • if too big: need to redo or grind down bars

summary of deliverables:
shem:

  • list of electrical components/stuff in enclosure (everything but the modules) for 11-11-2023

  • assign 3d printing to new members on sat 11-11 (enclosure feet, air baffles & diagonal supports)

  • send update about asc email 05-11

  • Hydrophobic mesh for inlet 11-11

nicole:

  • jigging as soon as everything is done

  • machining to be done?

jenna:

  • will cut mdf (will be checked by nicole for wed)

  • modify aux bat for securing m4 for 10-11

  • air duct will confirm with micheal there is 2

  • assign machining as soon as gotten

update: email from asc securing method can be done with pack itself

  • sealing required for impounding

  • can secure another method post-assembly for during race (ie. fishing wire through modules)
