Publication number: 20030221884Abstract: The invention relates to a hybrid power driving apparatus and its controlling method, especially using different types of power sources to cooperate them in parallel with each other. Due to a way of combining power sources in parallel, a single power source is able to be operated independently for not wasting energy under a condition of not combining power sources. The hybrid power diving apparatus comprise at least one controlling system apparatus, one electric driving apparatus, one fuel driving apparatus, one auto-control clutch apparatus and one integrated power assistant apparatus.Type: ApplicationFiled: August 13, 2002Publication date: December 4, 2003Applicant: Industrial Technology Research InstituteInventors: Ping-Huei Shu, Chien-Tsung Wu, Chi-Tang Hsu, Chun-Hsien Lu, Kai-Ching Hsieh, Chih-Chung Lo, Tzeng-Te Wei, Huan-Lung Gu

Publication number: 20030105562Abstract: The present invention is a power output control system for electric vehicle with hybrid fuel cell, which is an optimal design of DC/DC converter and applies the controller area network (CAN) as a connected instrument for communication to make a power source tend to be more flexible. When the invention is designed in the states of medium and low loads (for example, cruise in constant speed), the main electric energy supplied by the fuel cell boosts the fuel cell to an appropriate voltage through the control of DC/DC converter. While in the state of high load (for example, transient acceleration or uphill creep), the fuel cell may be served as an on-board charger. Not only the fuel cell may provide a maximum base load of electric power, but also the remaining requirement of electric energy is matched with the additional output of electric energy supplied by a high power secondary battery.Type: ApplicationFiled: November 30, 2001Publication date: June 5, 2003Applicant: Industrial Technology Research InstituteInventors: Jui-Sheng Hsiao, Chien-Tsung Wu, Chi-Tang Hsu, Jin-Chyuan Hung, Ping-Huei Shu
