Patent number: 8970341Abstract: Disclosed is an electric vehicle, a battery charging station, and an electric vehicle battery exchange reservation system including the same. The electric vehicle includes a power level detection unit adapted to detect a power level of a battery mounted on the electric vehicle; a communication unit adapted to communicate with a battery charging station; and a control unit adapted to determine a battery charging station, in which the battery of the electric vehicle is to be exchanged, based on the power level of the battery and a route of travel of the electric vehicle and transmit a battery exchange reservation command to the determined battery charging station. Based on the battery power level of the electric vehicle, a battery charging station existing along the route of travel is requested to provide battery information, and battery exchange is reserved accordingly, so that batteries can be exchanged more efficiently and conveniently.Type: GrantFiled: June 25, 2012Date of Patent: March 3, 2015Assignee: Kookmin University Industry Academy Cooperation FoundationInventors: Jun-Seok Park, Won-Kyu Kim, Hee-Jeing Park, Hee-Seok Moon, Wong-Chul Choi, Jay-Il Jeong, Chi-Man Yu, Do-Yang Jung, Yong-Hark Shin, Jae-Hong Park
