DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric vehicle having a generator, and more particularly, to an electric vehicle that can be used similarly to a gasoline vehicle or a diesel vehicle.

[0002]

2. Description of the Related Art As is well known, in order to solve the problem of air pollution in an urban area or around a high-traffic highway, a motor which is driven by electricity which is quiet and does not emit exhaust gas is used as a power source. Electric vehicles are attracting attention, and their widespread use is strongly desired. Research and development for practical use of electric vehicles are being conducted.

[0003] The electric vehicle is a motor as a power source.
And a battery for supplying electricity to the motor, and the performance of the motor has been improved by the research and development for the practical use of the electric vehicle. By devising the driving method, the speed performance and the acceleration performance have reached the same level as those of gasoline vehicles and diesel vehicles.

[0004] However, the size and weight of the battery mounted on the electric vehicle are limited, and the capacity thereof is also limited. Dozens of kilometers
It is not enough for usability, and it takes several hours to charge the battery, and it is an electric lamp that is a facility for charging the battery of an electric vehicle with electricity. Currently, there are few facilities such as
The electric vehicle is limited to the range of one charge travel distance, so that the electric vehicle can be used only in a very limited manner and cannot be used freely like a gasoline vehicle or a diesel vehicle.

Furthermore, in order to spread electric vehicles widely, it is necessary to improve not only the performance of the electric vehicles (particularly, the extension of one charge traveling distance) but also the maintenance of an electric stand for charging the electric vehicles. However, under the current situation where electric vehicles are not widely used, it is difficult to maintain electric stands and the like, and it has been very difficult to widely and widely use electric vehicles.

Therefore, the usability of the electric vehicle is improved,
In order to promote its spread, a hybrid type vehicle combining a motor and an engine (a gasoline engine, a diesel engine, etc.) has been proposed and put into practical use. This hybrid vehicle uses, for example, a motor as a driving force when the vehicle travels in an urban area, and uses an engine and a motor in a suburb or a highway according to the traveling location. Tar
Can be used by switching.

[0007]

According to an automobile in which the above-mentioned motor and engine are combined, the use of the motor in an urban area where acceleration and deceleration are frequent causes problems of air pollution and noise. In an urban area where it is quiet, it can take advantage of the quietness and no emission of exhaust gas, and can travel without problems even if the traveling distance per charge is short. In suburbs and highways where constant-speed driving is possible, the use of an engine enables long-distance driving while minimizing emissions. That is,
The advantages of both the motor and the engine can be obtained. However, using the engine, which is also the above-mentioned heat engine, as the driving force of an automobile causes load fluctuations such as acceleration and deceleration due to the running of the automobile to be applied to the engine, leading to gas emission and noise from the automobile, and the original electric vehicle It was out of the purpose of disseminating.

Accordingly, an object of the present invention is to realize long-distance traveling, which is difficult for electric vehicles in the past, while minimizing air pollution, and to obtain the same usability as gasoline vehicles and diesel vehicles. And to promote the spread of electric vehicles.

In order to achieve the above object, the present invention has the following technical means. That is, this will be described using reference numerals in the accompanying drawings corresponding to the embodiments,
The present invention provides a generator 2 that generates electricity by burning a combustible fuel;
Driven by the supply of electricity generated by the generator 2;
A motor 7 for rotating a drive shaft of the electric vehicle 1, a battery 6 which is charged by being supplied with electricity from the generator 2 and supplies electricity to the motor 7,
Are mounted together with the electric vehicle 1, and the motor
When the generator 2 generates electric power, the generated electric power is supplied to the motor 7 and the battery 7 is driven.
When the generator 6 is not sufficiently charged, the generator 2 supplies electricity to the motor 7 and also supplies the battery 6 with electricity. When the generator 2 is stopped, the battery 6
An electric vehicle provided with a generator, wherein electricity is supplied to a motor 7 from a motor vehicle.

Another characteristic feature is that the electric vehicle 1 is a luggage transport vehicle having a luggage loading section 12 for loading luggage at a rear portion thereof, wherein the generator 2 and the battery 6 are used. It is characterized in that it is mounted on the luggage loading section 12.

The electric vehicle 1 is a passenger car having a box-shaped body, and includes the generator 2 and an AC / DC converter.
The motor 5, the battery 6, and the motor 7 are mounted in a front portion 11 of the electric vehicle 1.

The generator 2 includes a generator main body 3 and an engine 4, and the engine 4 uses natural gas, LP gas, gasoline, light oil or the like as fuel. The generator 2 used in this example will be specifically described.
And the generator body 3 is a single-phase 50 Hz, 4 PO
LE, output 6.5 kVA, voltage 200 V, current 32.5
A is an AC generator. The engine 4 is a diesel engine having a rated output of 11 PS / 1500 rpm. The external dimensions of the generator 2 are 925 mm in overall length, 574 mm in overall width, and 690 mm in overall height, and the weight is 225 kg.
It is.

Next, the AC / DC converter 5 converts the AC current generated by the generator 2 into a DC current, and
The power is transmitted to the battery 7 or the battery 6, and in this example, it is a 200 VAC / 120 VDC converter.
Next, as the battery 6, a lead storage battery having a voltage of 12 V and a capacity of 90 Ah for 5 hours is used. The external dimensions of the battery 6 are 513 mm in overall length, 189 mm in overall width, and 223 in overall height.
