DESCRIPTION OF THE INVENTION

This invention is a convenient, automatic system to charge an electric vehicle, or a hybrid vehicle, during its travel on a road.

What sets this invention apart, is that the electric charging is done during normal driving on a special road, and solves a problem.

This is a convenient, automatic charge method, wherein the driver does nothing except driving. Electric vehicles do need to be charged with electric power sufficient to reach their destination, which is not always the case? This invention provides for a convenient method to accomplish this charging while driving onto a specially prepared road.

This road is having electrical contacts on a fence by the side of the road.

It could be a one-way direction roadway, with a wall on one side, having a non-conducting enclosure containing two stationary electrical contacts which are supplying current, mating with two electrical receiving conductive contacts in the vehicle.

These conductive electrical vehicle contacts are extendable and retractable from the vehicle, to their proper position. The two or more contacts make a good electric connection by a design that has a spring-loaded construction.

The vehicle contacts are supported by a non-conductive enclosure which can be totally invisible when retracted into the vehicle. The continuing enclosure in the wall of the charging road, can have protecting sheets made of non-conductive material, of rectangular, round or oval shape.

The electrical strips inside the non-conductive enclosures, are constructed of a low resistance, high conductance material for securely transferring the electrical current into the vehicle.

The enclosures are mounted on a supporting fence.

The fence is preferably made from corrugated or indented material to increase its stiffness and strength, but still be cost-effective.

The enclosures are mounted interlocked with the fence, which could have a support wires, to resist high wind or snow.

The fence, and its other components, can be mounted either on the on the left side or the right side of the road, depending on the customs of the country where it is installed.

To deter animal and birds to stay around the charging road, a high frequency annoyance signal can be used.

For test purposes of this inventions feasibility, a short section full size fence, with some electrical contacts, have shown surprising results.

The inventor has studied the literature without finding any specific prior art.

Only when a vehicle enters the charging road, the charging current is turned on, to save power during non-use. Sensing for the vehicle can be done optically, magnetically, by LED or by GPS.

The vehicle could enter the prepared charging road at low speed, or it could enter at a designated speed for that section, with earlier entering, and later entering vehicles, both having a uniform speed.

If this invention would be used for “self-driving” vehicles, it would allow the driver of the vehicle having a rest during the charging period on this “charging road”. This could be very important for drivers of truck vehicles. Another self-driving application is for delivery vehicles of packages, luggage or materials.

The cost for the electric charge, could be automatic by a license-plate scanner. After the vehicle enters the charging road, the conductive electrical vehicle contacts are extended to contact the semi-tubular electrical strips.

These conductive electrical strips can either have AC (alternating current or DC (direct current).

Additionally, an alternate charge method can be used, by having mating primary and secondary inductors that inductively transferring AC power from the strips to a secondary inductor in the vehicle.

This type of inductive transformer coupling between closely spaced inductors can be accomplished during the vehicle motion on the charging road. This inductive transfer can also be done with a high frequency for better efficiency.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is showing the vehicle traveling on a charging road with the the receiving contacts in the vehicle extended.

A supporting corrugated fence, is shown in dashed lines, mounted on the road bed either with cement or with fastener.

The vehicle is shown with several attached guidance and safety gear.

FIG. 2 is showing a larger view of the receiving contacts, in center of the charging contacts attached to a fence.

FIG. 3 is showing the top of the vehicle with its many accessories.

DETAILED DESCRIPTION OF THE DRAWINGS

FIG. 1 is showing the vehicle 10 traveling on a charging road 12 with the the receiving contacts 14 in the vehicle extended.

A supporting corrugated fence, 16 is shown in dashed lines, mounted on the road bed 18 either with cement 20 or with fastener.

FIG. 2 is showing a larger view of the receiving contacts, 40 attached to the non-conducting arm 14 having a spherical attachment point 42 that is fit into a hollow non-conducting spherical cavity in the vehicle 10, not shown. This cavity allows the arm 14 to adjust itself both up and down, as well as side-ways, and also be folded into the body of vehicle 10. The contacts 40 have electrical connections to the vehicle, not shown for reason of clarity of the Figure. At the end of the arm 14 is a spring loaded non-conducting plunger 44 to prevent accidental touch. Along the arm 14 is a non-conducting rectangular top 51 and bottom 52 sheet having attached charging contacts 53 and 54 carrying high charging current.

The charging contacts are only attached on one side for conformance and flexibility. The non-conducting sheets 51 and 52 has a curvature 55 and 56, and thereby having weak points for flexibility, before they are securely attached at 57 and 58 to fence 16.

An arrow 60 indicates the possibility of spring loading sheets 51 and 52, as well as opening them for entrance purposes.

FIG. 3 is showing a multitude of accessories on on the vehicle 10. These signify the several attached guidance and safety gear.

The above summary is not intended to describe each described embodiments or every implementation of the present invention.
