Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply device for a moving body, and more particularly to a power supply device comprising a group of storage batteries.

[0002]

2. Description of the Related Art A storage battery mounted on a moving body is mainly used for driving in an electric vehicle, and is used for a control power supply and lighting in an internal combustion engine vehicle. It is also used in conventional railways for the same purpose as internal combustion engine vehicles. In an internal combustion engine automobile or a conventional railway, a generator operates during running to supplement the natural discharge of the storage battery, while the load is borne by a charging device such as a generator, so-called floating charging.
Therefore, it is generally unnecessary to consider external charging before the life of the storage battery, except when the storage battery is not used for a long time. An electric vehicle is a vehicle that is charged during the night and used during the day because the storage battery itself is the driving power source.

[0003] A power supply device of a magnetic levitation vehicle that is levitated, supported, and driven in a non-contact manner by electromagnetic force, such as a superconducting magnetic levitation railway, includes an assembly of storage batteries and a non-contact current collector.
The non-contact current collector, a ground coil installed at a position on the ground opposite to the superconducting magnet mounted on the vehicle, a current is induced by the superconducting magnet by running the vehicle,
Utilizing the fluctuating magnetic field generated from the ground coil by this current, the current is collected by the induction current collecting coil arranged on the vehicle. The power collected by this non-contact power collector depends on the running speed of the vehicle, and when the vehicle is running at a low speed, sufficient power cannot be supplied to the load inside the vehicle. Supply.

FIG. 5 shows an example of a conventional on-vehicle power supply device applied to the floating railway. This is a state where the vehicle is stopped at a station or the like. A storage battery assembly 2 is provided in the vehicle 1, and a controller 4 required for controlling the storage battery and a fan 5 for cooling the storage battery are provided as auxiliary devices associated with the storage battery assembly 2. The fixing means 3 for fixing the storage battery assembly 2 and the accompanying auxiliary equipment is provided. For example, both the non-contact power collector 6 and the storage battery assembly 2 can supply power to the in-vehicle load 7 such as the interior lighting so that power can be supplied to the in-vehicle load 7 if necessary. The in-vehicle load 7, the non-contact power collector 6, and the storage battery assembly 2 are connected by a connection cable so that the assembly 2 can be charged. Since the non-contact power collecting device 6 does not function while the vehicle 1 is stopped, electric power is supplied to the in-vehicle load 7 from the storage battery assembly 2.

When charging the battery assembly 2, the current collecting shoe 10 is pulled out of the vehicle 1 and connected to the current collecting rail 9 provided on the ground. Electric power is sent from the ground power supply 8 to the current collecting rail 9. Therefore, the battery assembly 2 can be charged from the ground power supply 8. Current collecting shoe 10
Is drawn into the vehicle 1 while the vehicle 1 is running.

When the distance between stations is long, high-speed traveling is possible, so that the non-contact power collector 6 can collect sufficient power, so that power is supplied to the in-vehicle load 7 and the storage battery assembly 2 It can also supply power for charging. On the other hand, when the vehicle 1 cannot travel at high speed due to a short distance between stations or the like, the power collected by the non-contact power collector 6 is not enough to charge the storage battery assembly 2 by the non-contact power collector 6. Can not be done. Also, even when the vehicle is running at high speed, if the power consumption of the in-vehicle load 7 increases, the non-contact current collector 6
To charge the storage battery assembly 2 due to the above. In such a case, the storage battery assembly 2 is charged while the vehicle 1 is stopped at the station shown in FIG.

However, since the stopping time of the vehicle at the station is short, the charging is performed with a large current in a short time, so that there is a problem in the temperature rise of the storage battery and the life of the storage battery. by the way,
By displacing a power source such as an internal combustion engine or a storage battery device in a vehicle and its bearing device in a rearward and downward direction of a turning support portion provided in the vehicle, the bearing device turns in a direction away from the vehicle and is removed from the vehicle. The invention disclosed in Japanese Patent Application Laid-Open No. 49-25616 is disclosed. SUMMARY OF THE INVENTION It is an object of the present invention to quickly and easily attach / detach a power source such as a storage battery to / from a vehicle, thereby reducing the time during which the vehicle cannot be used during charging time by replacing the time with the power source.

[0008]

SUMMARY OF THE INVENTION Japanese Patent Laid-Open No. 49-2561
The invention disclosed in Japanese Patent Publication No. 6 is a floor cleaner, a lawnmower, a golf cart and the like as exemplified by the target vehicle, and the number of storage batteries is four and the number is exemplified. Therefore,
It is not intended for an aggregate (for example, 400 kg) of a storage battery having a weight that is mounted on an electric vehicle or the floating railway. It is difficult to attach and detach the assembly of the heavy storage batteries mounted on the electric vehicle or the floating railway vehicle according to the above invention. On the other hand, when considering charging a vehicle or other moving object with a battery pack mounted on it, the normal charging time of an electric vehicle is about 8 hours, and even a quick charge requires 30 minutes. Becomes

In a floating railway, the time during which a vehicle is stopped at a station is limited, so that the charging current for the storage battery to make up for the consumed electric power becomes very large, and the capacity of the device also becomes large. . In addition, the size of the cooling fan for preventing the temperature of the storage battery from rising due to the flow of a large current becomes large. In addition, there is a problem that charging with a large current significantly reduces the life of the storage battery. SUMMARY OF THE INVENTION The present invention has been made to solve at least one of the problems relating to the assembly of heavy storage batteries mounted on a vehicle as described above.

[0010]

In order to solve the above-mentioned problems, the present invention employs the following means. That is, in a power supply device composed of a group of storage batteries mounted on a moving body, the group of storage batteries is pulled out of the moving body at one time, and the group of fully charged storage battery devices is replaced at a time. Draw in. For this purpose, a guide device is provided on the aggregate of the moving body and the storage battery. Then, the storage battery assembly is fixed at a predetermined position in the movable body by a fixing means.
