Note

No specific dates since COVID might just screw everything up… will use time estimates 😢

Validation / Testing

  • Powertrain, MCI

  • Charger Interface

    • Elcon Charger to mockup battery

  • Precharge

  • BMS

    • Connect power supply to each channel, verify lower and upper faults

  • Solar Sense → can test outside (tongue) (MPPT layout)

  • Don’t have a load to test motors… Need to put it on the car

Further testing motors depends on mech (need rolling chassis)

BMS → dependent on battery, also need BMS Carrier assembled

    • HW validation for new versions

    • Notes:

      • Aashmika has the reflow at home to assemble most boards

      • if lockdown happens, this can still be done at Aashmika’s house.

    • Unit test boards once they return

      • if designs are flawed, board needs to be resent (at any stage)

  • Integrate into mockup (February) - must be onsite

    • Displays

    • Horn

    • Cameras

    • Telemetry Router

  • Mockup Testing

    • Solar

    • BMS Full (Pending Battery pack, and other testing)

    • MCI, Limit testing for Motors (includes carryover from F2020)

    • Full Mockup Integration (w/ displays)

    • Worst case: bleed into Spring

  • Complete all harnessing/make diagram for full vehicle (near EOT)

    • Includes layout

    • Note: this is offsite, if lockdown, will move this task to Jan

  • Finalize Enclosures Layout
    (to plan for post W2021)

...

Spring Term

  • Assembling Final Versions of Boards

  • Complete all board mounts

  • Complete all harnesses

  • Complete all enclosures

  • Assemble all items

Revisiting W21 goals…

  • Assembling final versions of boards

  • Motor Sense Validation (Hall-effect issues) - Weekend :)

  • High voltage testing 

  • Cell balancing + BMS Testing - in progress

  • Validation for final versions of boards (FW & HW)

  • Harnessing Planning ??

Fall 2021 Goals

Task

Notes

Timeframe

Integrate new hardware changes

  • No major/core firmware projects

  • focusing on integrating changes in a timely manner

CanExplorer

  • Aiming for demo in October, will try to get it to onsite members

  • An hour to review how to use the tool with onsite elec

  • Add to the onboarding / training plans

  • Could have a future training session targeted towards those that would maintain it

October Demo

MU

  • Led by Mitchell

  • has been fairly stagnant, will push for it next term to be used for integration testing

  • A way to get members familiar with the vehicle itself

Bootloader

  • Moving a bit slowly, hoping to deploy next term

  • New member migh tbe able. to help accelerate deployment

EOT

Board Sendout

  • Pedal, UV Cutoff and Precharge/MCI - no major changes but would be good for Firmware to check

  • PD has a small rev fix - had an issue about an enable put to a wrong pin 😞

2nd Week of September

Wiring Diagram

  • Diagram is basically done

  • Phase 2 should be done early next term but it might be delayed due to other priorities, not the end of the world

October

BMS / BPS Testing

  • Have the testing setup, to conduct testing of the system next term

  • Simulate what would be done during scrutineering, separate from other integration testing

  • Micah to write a test plan

  • Testing for current limits was done by soldering in an extra bridge to the amplifier

Charger Interface Testing

  • Not done…

  • Want to test with the VSC charger, ELCON charger communications, HV supply for input

  • Need to completely debug before potentially starting a new rev

Pick and Place Machine

  • First draft of safety manual is complete

  • Need to purchase all replacement equipment next term

  • Need to pick up the machine next term

Other:

  • Those familiar with vehicle architecture (apart from leads): Jess, Mitchell, Jarvis

  • No in-person onboarding component this term

  • Who will be onsite next term apart from Mitchell and Jess?

  • more CAN adapters…? Talk to Jess to see if there’s more equipment. the team may need/want?

  • Solar enclosure may be moved under the rear enclosure

Concerns:

  • MPPT issues - not consistent

  • Harnessing is blocked by mech in general

Boards (Onsite Progress)

  • Fully test Charger Interface

  • Testing AFEs and BMS to make sure we have thermistor readings

  • MPPTs don’t consistently boost, need to do more testing to see what’s wrong

  • Solar - Relay driver wasn’t working properly, need to replace the IC + conduct ideal diode tests

  • Debug Power Selection

  • Lights - have to test with higher driving currents if we need to make the lights brighter

titleEasy / Manageable

  • Reviews for all tasks together (smile)

    • Last Saturday of each month? Extended standup 😞

  • Buddy system (2-3 members w/ a lead)

    • Leads combine tasks to have groups work on them together (Kristen (smile))

    • Saturday work sessions

    • Standups once a week → Wednesdays

Expectations for Next Term

  • RETAIN MEMBERS 😃

  • Join On-Site weekly standups to get a better grasp of overall elec progress, improve knowledge

Next Steps

  • Kristen S to get everyone ready for onsite work (safety plan, etc.)

Term Layout - Remote Tasks

Wednesday standup to go over group progress - groups will give updates together
