FE1 was built during the 2013-2014 school year for the 2014 FSAE-electric competition in Lincoln Nebraska. UC Davis had not built a ground-up vehicle in several years. There had been a combustion team at UCD as recently as 2007-2008, and a Hybrid team subsequent to that. FE1 was built only during the 9 months of the academic year with the primary goal of building a simple, steel framed, dual-drive, rules compliant vehicle and passing tech inspection. Due to the nascent nature of the competition, we had reason to expect that simply being able to participate in dynamic events would produce a good outcome regardless of achievement of ideal vehicle performance. As it turned out this goal was both well matched to our resources and indeed produced a good outcome. FE1 became the first vehicle from a USA university to completely qualify and run dynamic events at FSAE-electric, and the only one in the 2014 competition, allowing us to take third place overall.
The construction and campaigning of FE1 was an immense group effort which included engineering students from all academic years, culminating in the travel of 22 students and our adviser Roland Williams to Lincoln, NE.
I was mostly responsible for the design and construction of our traction battery pack, as well as collaborating on the design of our low voltage system, power electronics packaging, and dual-reduction drive. I also drove the during the brake test and first part of the endurance event.
