strain relief and grounding
- Modular panel based wiring
design
- More standardized wiring
diagrams across subsystems
Supervisory Control and Data Acquisition (SCADA)
SCADA Overview
Grounded Low Voltage (GLV)
Breakout Board (BoB) Safety Loop
Tractive System Interface (TSI)
- Pre-Charge / Discharge
- Firmware
○ Drive states
- Throttle Plausibility
- Testing Board
Tractive System Interface (TSI)
Pre-charge/Discharge Precharge: prevent the system from shoving too much power into the motor at once. Discharge: Discharges the motor controller when TSV is turned off.
Tractive System Interface (TSI)
Testing Board
- Throttle plausibility pots
- Drive states tests
- Brake Button
