Design Projects

Project	Status	To-do
Pedal Board	Created prototype with the potentiometer	Board review Board bring up Validation & integration
Steering Stalk	Tested different options to mitigate the EMI Tested differential I2C on solar slaves and master Tested ferrite and low-pass filter Testing the difference amplifier Tested the board and the steering stalk with 12V power supply	Board review Board bring up Validation & integration
Center Console	Tested the Schmitt trigger to debounce the noise	Board review Board bring up Validation & integration
Telemetry	Calder & Taiping	Not sure
BMS AFE	Designed and reviewed the rev 4 Unable to measure the isoSPI on the rev 3	Board bring up, validation, and integration
BMS Carrier	Tested the Schmitt trigger to debounce the noise	Design the circuit on Altium
BMS Current Sense	New members started to look into different options	Design the circuit on Altium
Controller Board	Decided not to redesign it Measured the ADC accuracy	None

Project	Status	To-Do
Motor Controller Interface	Help firmware investigate the MCP2515 CAN issues Measured the clock frequency of MCP2515	None
Solar Sense	Validated the solar slave ADC Validated the differential I2C on the slaves and the masters Validated the relay and the fuse on the solar master	More testing and integration with the solar system
Power Distribution	Finish the board bring-up & soldering One is working (need more testing) I damaged the other one when I try to fix the fuse sockets	Validation & Integration
Driver Display	Testing the new ambient light sensing circuit	Validation & Integration
Pre-Charge	Validated the fixes on the pre-charge Working on the next revision	Validation & Integration of the new revision
EV Charger	Validated the J1772 related circuits with the desktop power supplies and multimeter Working the the next revision	Testing the board with the EV charging station Integrate it with the inlet, charger and the battery

The car was not ready for testing on both track days
- The first track testing was cancelled due to a faulty resistor joint on the AFE
- The second track testing was cancelled due to a faulty relay in the battery box
The team did not have sufficient knowledge and experience to debug the issues before the deadlines
Took too long to find out the causes of the issues
There wasn't a plan in place or enforced to make sure the car is 100% ready the night before the track day

The new driver control board design requires more prototyping iterations and time than expectation
We should start to prototype the different designs much earlier in the term
The new members need time to learn how to use Altium and familiarize with hardware team's workflow

Did not take advantage of the project management tools to make sure the projects on track
The planned deadline is not being enforced
Did not account for the prototyping time
