DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric vehicle configured to connect a power-supply mobile vehicle containing a secondary battery having a predetermined power capacity to a main body of an electric vehicle so that the power-supply mobile vehicle can be pulled and run. The present invention relates to a motor vehicle, and more particularly to an electric vehicle having an electrical connection structure for facilitating attachment and detachment of the power supply mobile vehicle.

[0002]

2. Description of the Related Art In general, an electric vehicle uses a secondary battery as a driving power source. However, there is a limit to the power capacity of a secondary battery that can be mounted on a vehicle. / 4 is short. Recharging of the secondary battery takes several hours in a general method, and it is not possible to run during that time. In response to this problem, there is a need for a charging method in which charging can be repeated while the vehicle is parked at a time and place where the electric vehicle is not driven, for example, at home, at work, at a parking lot, etc. There are still problems in securing security and collecting fees. on the other hand,
The rapid charging method, which performs supplementary charging on the road as an emergency measure, forces a large voltage and a large current, shortening the battery life, increasing the power demand gap between day and night, and queuing queues on the road. Many problems have been clarified, such as the expected situation.

[0003] In the case of business electric vehicles such as buses, trucks, and forklifts that use the power of a secondary battery as a power source, the discharged secondary battery is charged by a special facility provided at a specific location. A method of replacing the battery with the next battery and mounting it again is adopted. However, this method is not suitable for general vehicles.

[0004] As described above, there are problems in both charging in the state of being mounted on a vehicle and replacing the secondary battery with a new one. Therefore, there is an interest in increasing the energy density of the battery itself. Effort is being directed.

The inventor of the present application has previously proposed a power supply device for an electric vehicle to cope with a so-called dead battery on the road of the electric vehicle (Japanese Patent Laid-Open No. 7-76228). This device is a power supply device which is a moving body in which wheels are attached to a battery pack containing a secondary battery of a driving unit amount. When an electric vehicle runs out of battery, it is mechanically connected to the electric vehicle. The secondary battery power from the power supply device is supplied to the electric vehicle.

According to this method, the battery exchange is converted into a connection between two mobiles, an electric vehicle and a power supply, between the two. Since this operation is relatively simple, a dead battery can be relieved in a short time. In addition to the purpose of relieving the dead battery, a system has been constructed in which a charged power supply device is made to stand by at a site arranged at a fixed distance interval, and the discharged power supply device is replaced with a charged one at that site. If it is possible to replace the electric vehicle, it has the advantage that long-distance running of an electric vehicle, which has been considered impossible until now, can be performed for the first time.

[0007]

However, there still remains a problem in the electric vehicle power supply device. For example, it is not easy to connect a power supply cable from a power supply device to an on-vehicle battery of an electric vehicle or a line from the on-vehicle battery to a drive motor every time connection is made. In addition, when the connection is easily performed, the power remaining in the vehicle-mounted battery and the externally supplied power are mixed and leveled, so that it is impossible to use two power supplies having different discharge depths properly.

[0008] Further, the power supply device can be configured as a train by connecting one or a plurality of the power supply devices to an electric vehicle, and the train configuration can be simply physical transportation of the device or power supply to the electric vehicle. Despite being able to increase and / or increase resources,
A power supply method for realizing the proper use has not been established. In addition, the power supply cable needs a thick cable because of a large current power supply, and is difficult to handle. The power supply cable may be loosened and cause various failures. Further, apart from the power supply cable, a line to the lights and the like which needs to be provided in the power supply device at the end of the train configuration also needs to be wired through the train configuration. The plurality of cables to the lights also had problems such as difficulty in connection and looseness.

The present invention has been made in order to solve the above-mentioned problems of the prior art, and has a connection structure between an electric vehicle main body and a power supply mobile vehicle containing a secondary battery, and a selective use of a plurality of secondary batteries.

The electrical connector and the repeater can be configured to have a common structure. In addition, since the terminal plate of the electrical connector and the terminal plate of the repeater are pressurized face-to-face, the two terminals are brought into pressure contact with each other, and a good conductive connection is made.

Further, the electric connector and the repeater may be configured to include a terminal block on which connection terminal plates for electric circuits are arranged in a row, and a lid for opening and closing the terminal plate of the terminal block. Further, since it is possible to switch the electric circuit in conjunction with the opening and closing operation of the lid of the electric connector, the terminal can be connected by the lid when the electric connector and the repeater are not used. By closing the base, it is possible to prevent foreign substances and contaminants from entering the terminal portions arranged in the terminal base. In addition, the lid of the electric connector provided at the rear of the power supply mobile vehicle, which is the last in the case of the train configuration, is closed because there is no fitting connection of the repeater. The tail is recognized, and the electric circuit can be switched in conjunction with the opening and closing operation of the lid so that the lights can be turned on. It is also possible to perform line switching of an auxiliary device such as providing a generator in a power supply mobile vehicle.

Further, since the electric connector and the repeater can be formed in a common structure, and the electric connector and the repeater can be manufactured as the same member, the number of members constituting the electric vehicle can be reduced. In addition, manufacturing costs can be reduced.
