Owned by Taiping Li
Jun 17, 2019

- 8.1.H: Do we need sample solar cells? Do we have any spares?
- 8.2: Buy unaltered samples of cells (Eric Chiang)
- 8.2.C: Buy battery powered fans for drivers?
- 8.2.C.2: Why does the NiMH battery not work the whole time?
       o Look at waveforms when relays are closing
- 8.4.A: Check isolation between HV GND and GND
- 8.4.C: Check battery markings (Caution Chemical Hazard and High Voltage)
- 8.4.F: Get Eric to replace fishing wires for batteries
- 8.6.A.3: Label on power button that says POWER, PUSH ON
- 8.6.A.4: Verify that ALL HV relays open when the power switch is hit, or when the vehicle is in a safe state
- 8.6.B: Check BPS indicators
- 8.8.C: Test cruise control, make sure deactivates when the brake or accelerator pedal is pressed, or when car is shut off
- 8.9: Label all solar and PJB enclosures with High Voltage (min 10mm)
- 8.9: Check all thermistors for exposed conductors
- 9.4.A: Fix DRLs, check functions for all other lights
- 9.5.E: Check new camera for rear vision



General

- How are we doing telemetry?

- How are we doing radio/communication?

- Spare fans

- Rewire motor x2

- Harness for Power supply/lead acid battery (with reverse bat protection)

- Take inventory of connectors, screws, nuts, and inserts. Do we need to order anything?

- Get a long ethernet cable?

- Long extension cord?


Power Distribiution Validation
- Check DC-DC UV when turning on?
- Increase DC-DC voltage to 12.5 or 13V

Solar Sense
- Try reset in FW
- Probe I2C if needed
- Finalize MPPT calibration in the sun


Spare Boards Needed (* means we should have the parts already) 
- BMS Current Sense (ISEN) x1
     - Note tantalum capacitors are polarized
     - Don't put board into sense resistor yet
- Motor Interface/Precharge (PRE_CHG) x1
- Driver Controls Pedal (PDL_2.1) x1
- Driver Controls Center Console (DCC) x1
- Driver Controls Steering (STR_3.1) x1
    - One of the pads aren't connected. Need to solder it first
- AFE (AFE_5) x3
    - Inductor is different. Validate regulator...
    - Use LTC6811-1 instead of LTC6804-1 for U1
- Lights (LGHT) x1
    - Need to cut a trace on the board
- Controller Board (CB_7) x3

- Solar Master*
- Solar Slave*
- DC-DC*

- BMS Carrier (some parts)
- Power Distribution Rev 3
