Abstract

PURPOSE:To charge a battery fully until an automobile reaches its destination by charging the battery of the automobile while it is transported by a traffic means such as a railroad vehicle, a marine vessel or an automobile. CONSTITUTION:A railroad vehicle 1 has an electric power receiving equipment to which an electric power is supplied from a stringing 3 through a pantagraph 2 and an equipment to sent the electric power to an electric motor while controlling it. While an automobile 6 is transported, a charging cable is connected to the automobile. The electric power obtained from the stringing 3 through the pantagraph 2 is supplied/charged to a battery of the automobile after an alternating current, a direct current, voltage, an electric current and so on are converted/adjusted suitably for charging by means of a voltage/electric current regulator 5 being a charging device. Since an automobile transporting time is sufficient for charging the battery, the battery of the automobile 6 is put in a fully charged condition while it is transported, so that the automobile 6 can be operated immediately after it is transported.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a transportation machine such as a railroad vehicle, a ship or an automobile for transporting an automobile, and more particularly to a structure suitable for charging a battery of an electric vehicle being transported.

[0002]

2. Description of the Related Art In recent years, with the deterioration of air pollution caused by exhaust gas from automobiles, electric vehicles have been rapidly put into practical use as clean automobiles that do not emit exhaust gas. However, there are problems in advancing the practical use, that is, the distance that can be traveled by charging the battery once, that is, the one-charge traveling distance is short and it is not suitable for long-distance traveling, and the time required for charging the battery is long. It may be difficult to charge on the go (Fukino, Irie, "Current and Future Prospects of Electric Vehicles", Automotive Technology, Vol. 45, No. 8, 1991 August)
Month). Considering the characteristics of such an electric vehicle, the electric vehicle is suitable for moving within a city, but at present, is not suitable for moving between cities that are distant from each other.

On the other hand, railway vehicles, ships such as ferry boats, and trucks for land transportation are commonly used as transportation means for moving automobiles over long distances. However, these means are designed exclusively for the transportation of conventional motor vehicles with internal combustion engines. Therefore, it was not made in consideration of the transportation of electric vehicles and the operation after the transportation.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide means for efficiently moving an electric vehicle between long-distance cities and operating it after the movement by using a transportation means such as a railroad vehicle, a ship or an automobile. To do.

[0005]

In order to achieve the above object, the vehicle transportation means of the present invention comprises a device for charging a battery of a vehicle being transported.

[0006]

The vehicle transporting machine of the present invention loads a vehicle and transports it to the destination. The transportation time is relatively long, and the battery is charged using this time. Therefore, even when the battery of the automobile is almost discharged when it is mounted on the transportation machine, the battery is fully charged by the time it reaches the destination. Therefore, after arriving at the destination, the vehicle can be driven immediately without waiting for charging.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an explanatory view of an electric railway vehicle for automobile transportation, which is a first embodiment of the present invention.

The railway vehicle 1 has a power receiving facility to which power is supplied from the overhead line 3 via the pantograph 2 and a facility (not shown) for controlling the power and sending it to an electric motor. On the other hand, a part of the supplied power is connected to the input side of the voltage / current regulator 5. The vehicle is equipped with a loading facility for the vehicle 6.

During transportation of the vehicle 6, a charging cable is connected to the vehicle. The electric power obtained from the overhead wire 3 via the pantograph 2 is converted into AC / DC, voltage, current, etc. by a voltage / current regulator 5 which is a charging device so as to be good for charging,
It is conditioned, fed to the car battery and charged. Since the vehicle transportation time is sufficient to charge the battery, the battery of the vehicle 6 is fully charged during transportation, and the vehicle 6 can be operated immediately after transportation.

If the voltage / current regulator 5 incorporates an overcharge prevention device, an overcurrent prevention device, a leakage prevention device, etc., the safety is further enhanced. If a built-in watt-hour meter is used, the amount of electric power required for charging can be known, and the charging fee can be calculated.

Some electric railway vehicles have a function of regenerating electric power by causing an electric motor for self-driving to act as a generator during deceleration or gradient descent. In the case of a vehicle having this function, regenerative electric power may be used for charging in addition to electric power supplied from the overhead wire.

The utilization of these peripheral devices and regenerative electric power is not limited to this embodiment but can be applied to all the embodiments described below.

FIG. 2 is a block diagram of an automobile transportation train according to a second embodiment of the present invention.

The automobile transportation train comprises a vehicle 1 and an accompanying vehicle 1'having the same functions as in the first embodiment. Charging power supply lines 7 are installed inside each vehicle, and they are connected at a connecting position. The vehicle 1 is provided with a voltage / current regulator 5 for converting a part of the electric power supplied from the overhead wire 3 via the pantograph 2, and its output end is connected to a charging power supply line 7.
Cars 6 loaded from charging power supply line 7 inside each vehicle
A distributor 12 is provided for distributing power to the.

In the present embodiment, electric power for charging is supplied from the overhead wire 3 to the voltage / current regulator 5 via the pantograph 2 during transportation of the vehicle, and after a predetermined conversion, the charging power supply line 7 is supplied. Sent. Each distributor 12 further converts this electric power so as to suit the performance and state of charge of each vehicle and supplies it to the vehicle via a cable.

According to this embodiment, the batteries of a plurality of automobiles (for example, automobiles 6, 61, 62 in FIG. 2) mounted on a plurality of vehicles can be charged by one set of power receiving and converting equipment. The method of supplying charging power to the batteries of a plurality of automobiles using the charging power supply line 7 is not limited to the second embodiment of FIG. 2 and can be applied to all the embodiments described below. .

FIG. 3, FIG. 4 and FIG. 5 respectively show a third embodiment of the present invention, which is a diesel railway vehicle for motor vehicle transportation,
The structures of an automobile transportation ship according to the fourth embodiment and an automobile transportation automobile according to the fifth embodiment are shown. In both of these examples, a railroad vehicle 1 and a ship 8 which are automobile transportation machines.
The automobile 9 includes an internal combustion engine 10 and a generator 11 driven by the internal combustion engine 10. Internal combustion engine 1
