The goal of this project was to convert one of our customer’s retail low-speed vehicles from a diesel to electric drivetrain. Feedback from target-user interviews as well as mechanical modeling guided by basic vehicle physics were used to select new drivetrain components. The new drivetrain included a battery module with three recycled Tesla battery packs, a three-phase electric motor coupled to the original transmission (which was locked in 2nd gear), a motor controller which allowed for performance tuning and test data logging, and new cooling and throttling systems. The resulting prototype vehicle was tested under realistic conditions to verify its performance before delivery to the customer.
