Abstract: In case of branching a primary-side energy supply path into a plurality of secondary-side energy supply paths to supply energy to a plurality of supply targets, the energy supply to the plurality of supply targets is remotely monitored and efficiently controlled. A branch apparatus branches the primary-side energy supply path into the plurality of secondary-side energy supply paths. The branch apparatus is provided with secondary-side measurement means for measuring an energy supply status in each of the plurality of secondary-side energy supply paths, opening/closing means for opening and closing each of the plurality of secondary-side energy supply paths, and control means for transmitting information of measurement results of the secondary-side measurement means to a management apparatus and controlling the opening/closing means to individually open and close each of the plurality of secondary-side energy supply paths based on the control information received from the management apparatus.

Abstract: A utility vehicle is configured to cause an inverter to convert direct-current electric power from a battery into alternating-current electric power and supply the alternating-current electric power to an electric motor, and is also configured to cause motive power to be transmitted from the electric motor to a transmission case and then from the transmission case to a pair of left and right rear wheels. The battery is below a driver's seat. The transmission case is between the rear wheels. The electric motor is between the rear wheels and forward of the transmission case relative to the body. The inverter is backward of the battery relative to the body, forward of the electric motor relative to the body, and within the width of the battery.

Abstract: A vehicle includes an amount-of-power calculator, a power reception necessity determiner, a power transmission permissibility determiner, and a power transmission determiner. The amount-of-power calculator calculates an amount of necessary power for the vehicle. The power reception necessity determiner determines whether or not power reception of the vehicle from one or more other vehicles is necessary. The power transmission permissibility determiner determines whether or not power transmission from the vehicle to the one or more other vehicles is permissible. When two or more out of the vehicle and the one or more other vehicles make requests for the power reception, the power transmission determiner compares calculation results of the amount-of-power calculator of the vehicle and respective amount-of-power calculators of the one or more other vehicles, to determine priority of the power reception of the vehicle and the one or more other vehicles.
