ECE 492 Final Presentation

Major Highlights ● Integrated Dynamometer Testing Room using Vehicle Electronics Data Acquisition Software ○ ○ Grounded Low Voltage Breakout Board ■ ■ Safety Loop Tractive System Interface ○ ● New Motor and Motor Controller ○ Motor: EMRAX 208 ○ Motor Controller: emDrive 500 ● High Voltage Accumulator Management System Prototype Read and record cell voltage and temperature ○

Interconnect ● Mechanical Strain Relief ● Budget-conscious connectors ● High voltage rule compliant 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

Motor / Motor Controller / Dyno ● New Motor and Motor Controller ● Motor: EMRAX 208 ● Motor Controller: emDrive 500

Cooling ● Water Cooling the motor controller Quick disconnects added to TSI ● ● Sensors ○ Temperature Flow Rate ○ ● Powered through GLV and TSI ● VSCADA connectivity
