2021-04-28 S2021 Hardware Planning

Assembling final versions of boards

• PD, Lights, Steering, Solar, UV Cutoff, BMS Carrier

HIGH

4 months

Final designs for boards (for sendoff by EOT)

• Pedal, Precharge, UV Cuttoff?, Solar?

HIGH

4 months

Complete wiring diagram

• Make the importance of the tasks more clear

• Aren’t too far from completion

HIGH

End of June

MANDATORY WORK SESSIONS 😤

Finalize enclosure layouts

• Feedback for interiors

MEDIUM

dependent on Interiors

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 (MPPT layout)

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

MEDIUM

Further testing motors depends on mech (need rolling chassis)

BMS → dependent on battery, also need BMS Carrier assembled

HV integration into mockup

LOW

Telemetry, Headlights and Cameras (w/ Interiors)

LOW

Sorry, Renzo

All onsite tasks:

• Assembling final versions of boards (HW)

  • PD

  • PS (done)

  • Steering

  • Lights

  • Solar

  • UV Cutoff

  • Centre Console (done)

  • Current Sense (done)

• Motor Sense Validation (HW)

  • At the stage of integrating Sense to Controllers

  • Blocks all of Power Train

• High voltage testing (HW)

  • Integration Testing

  • Blocked by Motor Sense Validation

  • Blocked by Pre-Charge integration testing

• Assemble final versions of most boards (excl. AFE, DCDC, Charger interface, MCI) (January)

  • 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

Aashmika (School)

• Assembly of final versions of boards
• Precharge

• Onsite
• Available on most weekends
• Can possibly take some boards home to work on, during the week

Micah
(School)

• Motor sense validation
• Enclosures finalization

• On site, focus on battery box (1 month)
• Part-time + 3A… 😅

James L
(Co-op)

• Assembly of final versions of boards
• Telemetry Diagram

• Remote, will in in-person in Fall 2021
• Most likely can’t help

Nita
(School)

• Assemble PD (reflowed on side, hand-assembled the other side)
• Task force for diagram making

• Remote
• Can maybe visit on weekends but will be overloading during the term

Liam
(School)

• Assembly of final versions of boards

• Remote
• has equipment to do assembly / validation without being in loo

Kristen
(School)

• Harnesses?

• On Site
• Grunt work that requires limited hardware knowledge

Ricky
(Co-op)

• Onboarding?

• Onboarding 😃
