2. Project Summary At the start:
Already disassembled to only chassis, lights and tires
Several components were already picked out (e.g. BMS, contactors, motor controllers)
Progression
Designed an electrical system that replaces existing system
Determined components that will fulfill the needs of the system and client
Tested system-level components individually
Assembled most of the low voltage system and some of the high voltage system
Documented component list, testing procedures, future plans for improvements
CoE team has worked with the data acquisition system
Patrick has constructed the battery boxes, framing for motor controllers and plenty of other assembly.

3. Accomplishments 2 out of 3 battery boxes constructed
Isolated testing of
1 battery box (40V)
DC-DC converter
USB power adapters
Lighting system (headlights and front turn signal lights)
BMS
Motor Controllers
System wiring for most of the system (mentioned above) including the fuse box
DAQ from BMS to Arduino

4. Current System Design

5. Challenges Faced Technical challenges
Bypassing pre-charge resistor electrically
Fabricated relay circuit was not properly working
Management challenges
Broken or missing components
Delayed assembly time

6. Unfinished Tasks Isolated testing and integrating of Water pump
All 3 battery boxes
Construction of last battery box
DAQ from motor controllers to Arduino
Integrating relay circuit to close main contactor

7. Future Plans for Improvements
Replace mechanical secondary switch with a relay or alternative method to electrically maintain high voltage for DC-DC converter
Framing specifications
Replacement of 2 motor controllers for a single one
Addition of sensors for other features such as weight balancing
