Energy Management Control Systems for Electric and Hybrid Electric Vehicles
Researchers at Purdue University have developed an electric powered and regenerative braking power management system for an electric vehicle of any size, similar to a hybrid electric-human powered recumbent cycle driven by a brushless DC hub motor. The regenerated braking energy is captured using ultracapacitors and later transferred to the auxiliary battery or used directly to power the vehicle as needed. Because ultracapacitors can absorb large amounts of energy very quickly, they offer significant efficiency advantages over battery only regenerative braking systems. When desired, the flow of energy can be reversed in order to power the vehicle, especially in situations where sudden acceleration is required. The system is also modular. By using a unique printed circuit board similar to a mother board of a personal computer, users are able to add different functions by connecting auxiliary devices as needed. Lastly, this system, working additively with the human powered aspect of the travel, adds to the overall riding experience, leading to an increased value of the electric vehicle.
