  • Patent number: 10150384
    Abstract: Provided is a power control apparatus for a fuel cell vehicle which includes a fuel cell and which is driven by an electric motor that is supplied with electric power from the fuel cell. The power control apparatus includes an accelerator sensor that detects an operation of an accelerator, and a control unit that controls the fuel cell to increase the output power of the fuel cell so as to correspond to an increase in a requested acceleration output based on the detected accelerator opening degree. When the accelerator opening degree is less than a first accelerator determination value that is set in advance, the control unit controls the fuel cell to suppress an increase in the output power thereof.

  • Publication number: 20170365901
    Abstract: Provided is a warm-up apparatus for a fuel cell for an electrically driven vehicle in which a fuel cell and a secondary battery are mounted as power sources of a motor for travelling, and which, when charging of the secondary battery is required, stops operation of the fuel cell and charges the secondary battery with electric power from an external power source by means of a battery charger. The warm-up apparatus includes: a secondary battery cooling circuit that cools the secondary battery; a fuel cell cooling circuit that cools the fuel cell; a connection passage that connects the secondary battery cooling circuit and the fuel cell cooling circuit through a switching valve; and a warm-up control unit that, during charging of the secondary battery, controls the switching valve so that the secondary battery cooling circuit and the fuel cell cooling circuit communicate through the connection passage.
