Notes on DataAcq Presentation
Ishan's Notes
Race Strategy
Sensors
Data used for analysis
New peripheral board
Current:
- IMU (could be used actively in conjunction with motor control?)
- Airflow
- Temperature
- Tire Pressure (could be used for motor control?)
New Sensors
- Brake Pedal (why marked as new?)
- Should probably be under controls domain
- Steering sensor (useful for two wheel drive software differential)
- Atmo Pressure Sensor
- Humidity Sensor
Telemetry
- Regenerative Braking message over CAN (wouldn't this be encoded within the motor messages?) (what type of data do you want to see)
Dashboard (chase car)
- Not relevant to controls
Race Strategy
- Optimize track stuff
- Will be relevant to controls after this race, to integrate data acq race strategy stuff
- Monitors efficiency of the car
- Every 3 secs, outputs an optimal speed for the vehicle over CarCAN
- Could be integrated into display w/ driver notifications
Notes on Array Presentation
Ishan's Notes
- Power Electronics to track max power point to get most power out of array
- Bigger cells
- Make MISO and MOSI pins actually correct
- 1 RTD chip per 8 sensors with a decoder (with a select pin)
Notes on Power Systems Presentation
Ishan's Notes
- Manufacture HV battery pack
- Improve Battery Pack Safety
- Faster Manufacturing
- Better Power Usage
- Improve charging efficiency between battery and array
- Has there been any noticeable improvements from characterizing each cell individually that would be lost from just taking samples from each box?
- From current characterization stuff, how much do the cells each actually differ in terms of characteristics?
Notes on BPS Presentation
Ishan's Notes
Issues with current gen:
- Hardware uses non-standard and scarce chips
- Long wakeup time for isoSPI chips sampling
Goals:
- Standardize software drivers
- Transition to SOM
- New hardware to use common protocols
- How do you monitor the battery health now? Why is it a "nice to have" rather than "must have"?
- Wanna know how damaged the cells are
- We don't currently monitor the battery health
- Actively monitor isolation between frame and HV line (isolation is required by regs, but active monitoring is not (clarify this))
- Switch to CAN from isoSPI
- Tachometer feedback from fans
Stuff that may need to be addressed in PDR
Ishan's Notes
- Figure out dist. sensor before PDR so Aeroshell can make cutouts depending on size
- Wire harnessing wants a small board that they have to route less wires to in the back of the car (LIN? CAN?)
- Icons for steering wheel? Coordinate with Ergo to figure out
- Ask Akshay what he was saying to Philip and Steven about Regen stuff
