Description of the Related Art Exhaust gas from automobiles powered by gasoline engines or diesel engines accounts for most of the causes of air pollution, and the development of low-pollution vehicles is one of the most important factors for global environmental protection. Is essential for.
Therefore, electric vehicles have been attracting attention and are being put to practical use as vehicles without exhaust gas. Since this electric vehicle is equipped with a battery and is charged by the battery to run, the greatest advantage is that it does not require an internal combustion engine for burning liquid fuel and is pollution-free. The charging operation of the electric vehicle is performed by connecting a vehicle-side power source unit and a ground-side charger with a flexible cable or the like, and passing a current for a predetermined time.

走行が困難で、実用的ではないという課題もあった。However, such an electric vehicle requires a long time to be charged, for example, it currently takes 4 to 6 hours when fully charged by normal charging, and about 30 minutes when 40% charged by rapid charging. Even if charging is performed for such a long time, the traveling distance for one charging is short, and therefore it is necessary to frequently perform charging work. The flexible cable requires human intervention each time such charging work is performed. However, there is a problem that it is not practical to connect such devices. In addition, since a special power supply device for charging work is required for charging work, the place where charging work can be done is limited, the traveling range is limited, continuous running for a long distance is difficult, and practical There was also a problem that was not.

れる。FIG. 3 is a block diagram schematically showing the new transportation system. The microwave transmitting station 21 is provided with a position detecting signal receiving means 25, and a signal for notifying the position of the vehicle 22 transmitted from the position indicating signal transmitting means 29 via the antenna 29a is transmitted to the antenna 25.
It is designed to be received via a. The signal is input to the position determination means 32, and the position determination signal from the position determination means 32 is output to the microwave transmission control means 33 and the driving device 27. By inputting the position determination signal to the microwave transmission control means 33, the microwave from the microwave generator 34 is transmitted to the microwave transmission antenna 24 via the microwave transmission control means 33. The microwave is transmitted via a microwave transmitting antenna 24 which a drive device 27 follows in the direction of the vehicle 22 based on the position determination signal. On the other hand, the vehicle 22 is provided with the position detection signal receiving means 30 and the position indicating signal transmitting means 2
A signal for notifying the position of the microwave transmission station 21 transmitted from 6 through the antenna 26a is received through the antenna 30a. The signal is input to the position determination means 35, and the position determination signal of the position determination means 35 is output to the drive device 31. The driving device 31 drives the microwave receiving antenna 28 based on the position determination signal so that the microwave receiving antenna 28 can surely catch the microwave from the microwave transmitting station 21. The microwave received through the microwave receiving antenna 28 is converted into charging electricity by the converter 36 and charged in the battery 37.

ト部に収容されている。Embodiments of the battery charging system according to the present invention will be described below with reference to the drawings. FIG. 1 is a partially transparent perspective view schematically showing an embodiment of a battery charging system according to the present invention, in which 11 denotes a DC power transmission line. The DC power transmission line 11 is buried in the ground, for example, 0.5 m from the road surface 12, and performs 1500 V general DC power transmission or DC power transmission for electric railway vehicles. On the other hand, in the vehicle 13, the coil 14 including the iron core 14a for generating the electromagnetic induction current is provided on the road surface 12
The coil 14 is connected to one end of the rectifier circuit 15 at a height of, for example, 0.5 m. The rectifier circuit 15 is configured to include a diode (not shown), a capacitor (not shown), etc., so that the battery 16 can be charged regardless of the direction of the current flowing through the coil 14. The other end of the rectifier circuit 15 is connected to the battery 16. Although the coil 14, the rectifying circuit 15, and the battery 16 are illustrated as being arranged up to the door portion of the vehicle 13 in FIG. 1, all of them are actually accommodated in the front portion of the vehicle 13.

When IA power is being transmitted to the DC power transmission line 11 in the direction of the arrow A, a magnetic field C based on the Ampere's right-hand screw law is generated in the DC power transmission line 11. The strength H of the magnetic field C that the coil 14 receives is determined by setting the distance from the DC power transmission line 11 to the coil 14 to 1 by the above configuration.
Applying the Ampere Circular Theorem (2πrH = I) as m, the following equation is obtained.

The magnetic flux density B on the coil 14 side is expressed by B = μH. When the vehicle 13 travels in the direction of arrow D at a speed of Vm / s, for example, the coil 14 crosses the magnetic field C generated by the DC power transmission line 11, and an electromotive force E based on Fleming's right-hand rule is generated. . The magnitude of the electromotive force E is obtained by multiplying the magnetic flux density B (wb / m 2 ), the length (m) of the coil 14 and the moving speed (m / s) of the coil 14.

When electric power is being transmitted in the direction, a large electromotive force E is generated in the coil 14, and the electromotive force E is rectified by the rectifier circuit 15 into a flow of current in the direction for charging the battery 16 to charge the battery 16. It will be. Therefore, the generated electromotive force E
Due to the action of the rectifier circuit 15, the battery 16 is charged regardless of the power transmission direction of the DC power transmission line 11 and the traveling direction of the vehicle 13.
