  • 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.
    Type: Grant
    Filed: March 27, 2017
    Date of Patent: December 11, 2018
    Assignee: MITSUBISHI JIDOSHA KOGYO KABUSHIKI KAISHA

  • Patent number: 9837692
    Abstract: A power controlling apparatus includes a secondary battery (2) connected to an electrical device (4), and a fuel cell (3) connected to the electrical device (4) and the secondary battery (2). The fuel cell (3) has two non-generating modes including an idling mode and a halt mode, the fuel cell (3) suspending generation of power while being supplied with fuel in the idling mode, the fuel cell (3) stopping generation of power without fuel supply in the halt mode. The power controlling apparatus further includes a remainder estimator (11) to calculate the remaining number of starts representing the remaining number of available starts of the fuel cell (3), and a controller (16) to control the fuel cell (3) to be one of the two non-generating modes during a non-charging mode of the secondary battery (2), based on the remaining number of starts calculated by the remainder estimator (11).
