Trumbull High defended its alternative energy racing crown recently, completing 102 laps of Berlin Raceway in four separate heat races. The team raced an electric go-kart against teams from seven other state schools.
The race constraints are that teams are limited to a one-horsepower DC electric motor, and two 12-volt car batteries to power the vehicle. The go-kart works on basic electronics principles, the batteries are wired in series to make a combined 24-volt system. The difficult part of the race is that competitors aren’t allowed to recharge batteries in between the four 15-minute heats, so getting an efficient gear ratio is essential.
