Battery issues like weight, cost, charging time and infrastructure have been major obstacles to Electric Vehicle (EV) introduction to the market. As a solution, KAIST introduced the new concept of on-road wireless charging technology, called OLEV� (On-Line Electric Vehicle). In applying the technology, efficient power management, especially with Heating, Ventilation and Air-Conditioning (HVAC) system in electric vehicles remains as yet to be solved, in view of continuous and efficient energy management especially when operating on the electrified road. In this paper, unique feature of power control algorithm of HVAC system for OLEV� is introduced. The main purpose is to control the amount of power and energy consumed by HVAC system so that it does not affect any key performances of an electric vehicle in view of driving distance and speed. Specifically, the algorithm makes sure that HVAC consumes no more than 20% and 25% of instantaneously available power for air-conditioning and heating respectively by controlling the output of heating or cooling power from HVAC system, while maximizing the HVAC performance in customers' perspective. A proper set of dynamic models and control algorithms for a HVAC system is developed linked together with OLEV� system operation. With these models, simulations have been carried out to verify that the algorithm leads to optimized and improved performance of an OLEV�.
