  • Publication number: 20190039707
    Abstract: A power system of a ship includes a first power storage device, a second power storage device, and a control system. The first power storage device has an energy density higher than that of the second power storage device. The second power storage device has a power density higher than that of the first power storage device. The control system is configured to: as a power generator application, prioritize discharging the first power storage device over discharging the second power storage device, such that base power is continuously supplied to an onboard electrical load connected to an onboard bus; and as a grid stabilization application, prioritize charging/discharging the second power storage device over charging/discharging the first power storage device to compensate for frequency variation or voltage variation of an onboard power grid.

  • Patent number: 9975447
    Abstract: In a power storage system, a bidirectional DC-DC converter is set into mode for charging a secondary battery with electricity when a first state of charge (SOC) of the secondary battery is larger than a minimum value of the first SOC, and a second SOC of the capacitor is smaller than a maximum value of the second SOC, and the converter is set into mode for discharging electricity from the secondary battery when the first SOC is smaller than a maximum value of the first SOC, and the second SOC is larger than a minimum value of the second SOC. Based on an internal resistance of the secondary battery, the second SOC, a voltage of a direct current link in case of no load connected to DC link, and an error in a current on a direct current link side, a conduction ratio (D) of the converter is calculated.

  • Patent number: 8897937
    Abstract: A railcar control apparatus comprises a synchronous slide/slip detector which determines that the axles are synchronously sliding/slipping if an absolute value of axle's speed difference is less than a synchronous slide/slip speed difference threshold and an absolute value of axle's acceleration is greater than a predetermined synchronous slide/slip acceleration threshold.

  • Publication number: 20120004797
    Abstract: A construction machine comprises an electric motor/generator; an engine; an epicyclic gearing for rotating the electric motor/generator reversely when speed of a rotation output to a drive wheel is zero during running of the engine; a transmission configured to switch between a forward driving gear position and a backward driving gear position; and a controller for controlling the engine, the electric motor/generator and the transmission, based on at least an accelerator opening, and a state of charge in an electric storage device; the controller being configured to switch the forward driving gear position or the backward driving gear position to a direction opposite to a direction in which the construction machine is moving, and cause the electric motor/generator to generate reverse torque in a power running mode, when the electric storage device is in a fully charged state and the accelerator has been pressed down by a driver.
