Title:
電動車両の電源装置
Document Type and Number:
Japanese Patent JP6926549
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve the fuel economy of a fuel cell by increasing the time of generation of the fuel cell at its maximum efficiency output by limiting a vehicular output requirement in an electric vehicular power supply apparatus that includes the fuel cell and a secondary battery.SOLUTION: A power supply apparatus 3 of an electric vehicle 1 that has a fuel cell 5 and a secondary battery 7 includes a fuel cell control part 29 for controlling generation of the fuel cell on the basis of information from a charge state detection means 31 that detects a charge state of the secondary battery. Further, the fuel cell control part includes: a generation control part 33 for causing the fuel cell to generate at a maximum efficiency output when the charge state reaches a lower limit charge ratio or less and causing the fuel cell to stop generating when the charge state reaches a target charge ratio higher than the lower limit charge ratio; and a vehicular output limit part 28 for limiting a vehicular output requirement to the maximum efficiency output or less when the fuel cell generates at the maximum efficiency output under the control of the generation control part.SELECTED DRAWING: Figure 1
