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

Further testing motors depends on mech (need rolling chassis)
BMS → dependent on battery, also need BMS Carrier assembled

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

Reviews for all tasks together
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
)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
...
Let’s make a functioning electrical system that our team has confidence in

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
