摘要： A power supply system includes a main power storage device and a plurality of sub power storage devices. A converter is connected to a selected one of the sub power storage devices to convert voltage between the selected sub power storage device and an electric power feeding line bidirectionally. Connection of the sub power storage device is switched and, when the last sub power storage is used, a request to disconnect the sub power storage device is generated based on the SOC of the sub power storage device and the vehicle state. Specifically, where the SOC is included in a disconnection forced region in which the SOC is smaller than a reference lower limit, the sub power storage device is forced to be disconnected regardless of the vehicle state. Where the SOC is included in a disconnection permitted region in which the SOC is higher than that in the disconnection forced region, the disconnection request is generated on condition that the vehicle is in such a state that will not affect vehicle's drivability.

摘要： An electric powered vehicle includes a motor, an inverter, a main power storage device, and a plurality of sub power storage devices. A converter is connected to a selected one of the plurality of sub power storage devices to perform voltage conversion bidirectionally between the selected sub power storage device and an electric power feeding line. A control device executes a disconnection process to disconnect a selected sub power storage device from the converter based on a state of charge of the selected sub power storage device when there is no new sub power storage device that can replace the selected sub power storage device. Further, the control device executes a braking process for the inverter for regenerative braking by the motor. The control device prohibits, during execution of one process of a disconnection process and braking process, the other process.

摘要： A power supply control apparatus for controlling a power supply unit including a battery and a load is provided. The power supply control apparatus includes a main relay and a ground relay, a pre-charge relay, an inrush current limiting resistor, a first relay control section, and a time measurement section. The main relay and the ground relay are connected between the battery and the load. The pre-charge relay is connected in parallel with one of the main relay and the ground relay. The inrush current limiting resistor is connected in series with the pre-charge relay, and limits an inrush current from the battery to the load. The first relay control section temporarily turns ON the pre-charge relay and turns ON the main relay and the ground relay upon receiving a power supply connection request from the outside, and turns OFF the main relay and the ground relay upon receiving a power supply interruption request from the outside. The time measurement section chooses a time point in the period from when the pre-charge relay is turned ON to when it is turned OFF, and measures the elapsed time from the chosen time point. Before the elapsed time measured by the time measurement section reaches a predetermined reference period, the first relay control section does not turn OFF the main relay and the ground relay, but maintains the relays ON, even when receiving the power supply interruption request.

摘要： A two-way clutch is provided between an engine and a generator motor. Further, a battery and a cargo handling pump are provided. The generator motor is set to either a generator mode or an electric motor mode. When a cargo handling load (detected by a sensor) is small, the two-way clutch is set to a first state in which transmission of driving force from the engine to the generator motor is allowed and in which transmission of driving force in reverse is prevented. Further, when the engine is stopped or idled, the cargo handling pump is driven by the generator motor in the electric motor mode. When, during the above operation, the load increases to a level above a predetermined value, an increase in output of the generator motor and an increase in engine RPM are started, and when the engine RPM becomes equal to the RPM of the generator motor, which previously increased, the two-way clutch in the first state is connected, and the cargo handling pump is driven by the engine.
