摘要： PROBLEM TO BE SOLVED: To make a source of electric power have more flexible by making optimum design of direct-current/alternate current converter and a controller area network as the communication tools for connection. SOLUTION: The source of electric power is made to have more flexible by making optimum design of direct-current/alternate current converter and a controller area network (CAN) as the communication tools for connection. In the inside of electric vehicles, when it is a low load state (for example, it is in constant speed cruising), main electricity energy is supplied by the fuel cell, and the fuel cell is boosted to suitable voltage by controlling of DC/DC converter and the fuel cell can be used in an on-board charger. Moreover, when it is in a high load state (for example, it is in an instantaneous acceleration state or in climbing up a hill), the fuel cell provides the maximum base electric power and also it is made to output other required electric energies by combining the high power secondary-battery electricity energy added from the outside. Then, it is made so that it may have the combination type power supply output controlling function. COPYRIGHT: (C)2003,JPO
