As more and more electric vehicles emerge in our daily operation progressively, a very critical challenge lies in accurate prediction of remaining driving/flying time to distance. In case of electric aircrafts, computing remaining flying time is also safety-critical, since an aircraft that runs out of power (battery charge) while in the air will eventually lose control leading to catastrophe. In order to tackle and solve the prediction problem, it is essential to have awareness of the current state and health of the system, especially since it is necessary to perform condition-based predictions. To be able to predict the future state of the system, it is also required to possess knowledge of the current and future operations of the vehicle.
Our research approach is to develop a system level health monitoring safety indicator either to the pilot/autopilot for the electric vehicles which runs estimation and prediction algorithms to determine state-of-charge and estimate remaining useful life of the vehicle. Given models of the current and future system behavior, the general approach of model-based prognostics can be employed as a solution to the prediction problem and further for decision making.

NASA is extending our senses to see the farthest reaches of the universe, while pushing the boundaries of human spaceflight farther from Earth than ever before. Humankind is poised to take its Next Giant Leap, far beyond the frontiers of exploration we've reached to date. On Earth and in space, the agency is developing new capabilities to send future human missions to an asteroid and Mars. An unprecedented array of science missions is seeking new knowledge and understanding of Earth, the solar system and the universe. We're studying Earth right now through current and future spacecraft helping answer critical challenges facing our planet: climate change, sea level rise, freshwater resources and extreme weather events. NASA's aeronautics team is working with other government organizations, universities, and industry to fundamentally improve the air transportation experience and retain our nation's leadership in global aviation. NASA is with you when you fly. Every U.S. aircraft and air traffic control tower has NASA-developed technology on board.
