The MSU EcoCAR 3 team plans to transform the all-new 2016 Chevrolet Camaro into a plug-in series-parallel hybrid electric vehicle, powered by E85 gasoline, over the course of the 4-year competition. By selecting an aggressive and monumental architecture design, the team plans to make waves throughout the course of the competition.
The Mississippi State University EcoCAR 3 Team’s selected architecture includes a custom gear drive system and energy storage system (ESS). The custom gear drive will take three inputs and output to a singular shaft. The gears will be machined by a team sponsor, while the aluminum housing will be machined in house by the team. Coupled to the gear drive is a two speed under/overdrive transmission. The transmission will allow the team’s Camaro to reach speeds of up to 88 miles per hour (mph) in first gear and top out at 113 mph.In the rear of the Camaro is the team’s custom ESS which is designed with components from a competition sponsor, A123. The battery pack has a capacity of 18.9 kWh which will help the team reach 64 miles all electric range. The team will be fabricating both the ESS case and supports in house out of carbon fiber. Additionally, included in the team’s architecture is a two cylinder turbocharged engine that was originally designed for snowmobiles and wave runners. This light and compact engine puts out 120 horsepower (hp) and will be converted to run off of E85 gasoline. An 8.5 gallon tank will be installed in the rear of the vehicle. Estimations show the team will achieve around 50 miles per gallon gasoline equivalent (mpgge), bringing the MSU Camaro’s total vehicle range to just shy of 500 miles.Coupled to the team’s engine is one of three electric motors used in MSU’s architecture, a Bosch Integrated Motor Generator (IMG) which will be used to generate power for maintaining and recharging the ESS. The other two electric motors, UQM 125 and UQM 145, will be used to drive the vehicle. These motors, along with the custom gear drive, and two speed transmission will make it possible for the Camaro to output over 1000 ft-lbs of torque after the transmission.
