A method protects a battery in a fuel cell vehicle, in which an inverter-driven motor is supplied with electric power from the battery and a fuel cell. If a battery voltage of the battery falls outside of a prescribed range, a primary current and a secondary current that flow through the DC/DC converter, or currents in branch paths that correspond to the primary current and the secondary current, are reduced in order to limit a charging current flowing into the battery or a discharging current flowing from the battery.

The present invention is a compact fruit-vine harvester and separation system in which the harvested fruit travels along a vertical plane inside the harvester during processing, followed by a single turn for output. The system includes a machine and related methods for harvesting vine-borne crops. The machine is relatively compact, and provides for vine borne crops to be severed, separated, cleaned and machine-sorted along a straight path before making a single turn prior to exit. Harvested fruit passing through the machine experiences fewer drops than in other harvesters, thereby reducing the potential for fruit damage. The machine incorporates a blower and/or suction system for efficient removal of unwanted dirt, vegetation and debris, and an optional roller to prevent clogging of the suction system.

In an initial time of a warming-up control of a vehicle air conditioner, a control unit controls a mode switching member to set a foot mode, a first linear bi-level mode, a fixed bi-level mode, a second linear bi-level mode and the foot mode. In the first and second linear bi-level modes, a face-foot air blowing ratio between air blown from a face opening and air blown from a foot opening is gradually changed as the time passes. Therefore, the face-foot air blowing ratio can be smoothly changed in a mode switching between the foot mode and the fixed bi-level mode. Accordingly, when the mode switching is performed in the warming-up control in the winter, the face-foot air blowing ratio is prevented from being suddenly changed.
