Description

  The present invention relates to an overhead line-less traffic system in which a power storage device is mounted on a vehicle and travels a route set on a track while receiving power supply from a charging facility installed on the ground, before leaving from a standby base, By performing standby charging, it is possible to start while accurately maintaining the set charging state at all times, and to prevent overcharging and overdischarging of the power storage device, thereby extending the life of the power storage device. The present invention relates to a transportation system capable of charging and a charging method thereof.

In recent years, in a traffic system that travels on a track on which a vehicle is set, an overhead line-less traffic system using an electric vehicle that travels without receiving power from the overhead line has been proposed. An electric vehicle of an overhead line-less transportation system is equipped with a power storage device.
Such an overhead wire-less traffic system is disclosed in, for example, Japanese Patent Application Laid-Open No. 2000-83302.

  In the traffic system disclosed in Patent Document 1, when the vehicle stops at the stop facility, the power receiving means is electrically coupled to the external power feeding means, and the external power is supplied from the external power feeding means. The external power thus stored is stored in the in-vehicle power storage means as the stored power. When the vehicle travels, the stored electric power is taken out from the in-vehicle power storage means, sent to the electrical drive source, and the rotational speed of the electrical drive source is controlled to control the travel speed of the vehicle. When the vehicle is braked, the electric drive source is rotated as a generator, and the generated regenerative power is stored in the in-vehicle power storage means as the stored power.

  Patent Document 2 (Japanese Patent Laid-Open No. 2003-274514) discloses an unmanned transport system for transporting luggage to each room in a building having a large number of rooms such as a hospital. FIG. 7 is a schematic view of this transport system. In FIG. 7, this transport system includes a traveling track 01 and a carriage 010 movable along the traveling track 01, a battery is provided in the carriage 010, and the carriage 010 is loaded and unloaded on the traveling track 01. The station ST1 is provided with a plurality of stations ST1 for stopping, and each station ST1 is provided with a charging device 021 for charging the battery of the stopped cart 010. The charging device 021 is provided for a predetermined time after the stopping of the cart 010. And a second charging mode in which charging is performed with a charging current smaller than the charging current in the first mode.

  Also, a lifter 020 for moving the carriage 010 is provided at the station ST2 arranged on a different floor, and the carriage 010 can move between the traveling track 01 and the lifter 020. Further, the running track 01 is provided with a buffer BF1, which is an area for storing an empty carriage 010 that is not used, and the buffer BF1 is charged with a charging current smaller than the charging current in the first mode. A charging device is provided.

  With such a charging system, when the cart stops at one station, first, the first charging mode in which charging is performed with a large charging current, a large amount of power is charged to the cart battery in a short time, and the cart stops. After a predetermined time has elapsed, the vehicle is charged without applying a load to the vehicle by charging the vehicle in the second charging mode in which charging is performed with a small charging current.

  Patent Document 3 (Japanese Patent Laid-Open No. 2005-57878) discloses a battery charging equipment for an industrial electric vehicle such as an electric forklift. The charging device is a battery charging device capable of charging a battery in any one of a normal charging mode and a quick charging mode in which a battery is rapidly charged with a charging current larger than the normal charging mode, In order to prevent the battery liquid temperature and the temperature of the transformer, rectifier, etc. from rising excessively in the quick charge mode, the battery is charged when a predetermined quick charge time has elapsed since the start of charging in the quick charge mode. Once it is stopped, the charging mode is changed to the standby mode with zero charging current, and when this standby mode continues for a predetermined standby time, the charging mode is changed from the standby mode to the normal charging mode. ing.

However, the charging system of the transport system disclosed in Patent Document 2 is referred to as a first charging mode in which quick charging is performed with a large charging current and a second charging mode in which charging is performed with a charging current smaller than the first charging mode. Since two charging modes are provided and these two charging modes are switched and controlled, the control system becomes complicated, and the start and stop of the carriage is not so frequent and suitable for a case where the start and stop intervals are slow. In addition, as in the above-mentioned overhead line-less transportation system, the vehicle is charged in a short time at a stop facility such as a station building, repeatedly starts and stops frequently in a short time, and is not suitable when the stop time differs at each station. .
Similarly to Patent Document 2, the charging system disclosed in Patent Document 3 is a charging system in which there is a time margin in the charging interval, and the processing is too complicated, so that it frequently occurs in a short time like a vehicle. It is not suitable for a charging system for a large mobile object that repeatedly stops and requires a large current.

  The present invention simplifies the charging method in an overhead line-less traffic system using an electric vehicle in which a power storage device is mounted on a vehicle traveling on a set route, and the vehicle travels without receiving power from the overhead line, and By adopting a charging method that also considers maintenance during stand-by at the vehicle base, the vehicle is departed from the stand-by position while maintaining the charged state with high accuracy, and overcharging and overdischarging of the power storage device are prevented. It is an object of the present invention to propose a transportation system and a charging method that can extend the service life.

In order to achieve the above object, the traffic system of the present invention comprises:

  In the present invention, in a charging facility arranged on a route on which the vehicle travels, charging is performed with a constant current (constant power) capable of rapid charging, and when the vehicle stops traveling between stations and is waiting on a standby route, The power storage device (for example, a secondary battery such as a lithium ion secondary battery) is charged with a constant voltage, which reduces the temperature of the liquid storage device, transformer, rectifier, etc. excessively. Preventing the life of the power storage device from being lowered. In the present invention, charging on the vehicle travel route is limited to constant current (constant power) charging, so that it is not necessary to switch the charging mode during charging, and the device configuration can be simplified. Charging with a constant voltage can reduce the charging power source.

Therefore, the vehicle of the present invention applied to the traffic system and the charging method of the present invention is

Therefore, it is possible to start while maintaining a high degree of accuracy, so that overcharging and overdischarging of the power storage device can be prevented and the life of the power storage device can be extended.

Is connected in parallel to the secondary battery 12 at a position such as the bottom surface of the vehicle main body 10 that can face a ground-side power transmission device to be described later. The power receiving devices 13 and 14 may be connected to the secondary battery 12 in a switchable manner.

  FIG. 3 shows a state in which the vehicle body 10 stops on the track 2 beside the charging facility 20 installed in the station building 3.
