  • Patent number: 9088027
    Abstract: A plurality of cell units is stacked. A pressurizing mechanism applies a compressive force in a stacked direction to a stacked structure of the cell units. Each of the cell units includes a power storage cell, and a frame body which supports the power storage cell. The frame body includes a positioning portion which restrains a relative position with respect to a direction perpendicular to the stacked direction of the frame bodies adjacent in the stacked direction. The positioning portion positions the frame bodies with respect to the direction perpendicular to the stacked direction. A margin is kept in a direction in which the frame bodies are closer in the stacked direction in a state where the compressive force is applied to the stacked structure due to pressurization through the pressurizing mechanism.

  • Patent number: 8810210
    Abstract: A motor generator operates as a generator and a motor. A converter switches a discharge state where power is supplied from a capacitor to the motor generator and a charge state where the capacitor is charged by the power generated from the motor generator. Electric power that is output from the capacitor in the discharge state and electric power that is input to the capacitor in the charge state are controlled. A capacitor voltmeter measures a terminal-terminal voltage of the capacitor. A capacitor ammeter measures charge/discharge current of the capacitor. The measurement result is input from the capacitor voltmeter and the capacitor ammeter to a controller. The controller controls the converter based on the measurement result.
