Abstract
Abstract An electrically powered vehicle comprising at least one electric motor connected to a drive axle, at least one generator means connected to another axle whereby the rotation of the axle powers the generator means to produce electricity, batteries to provide stored electrical energy to said motor, transmission gearing means to increase the rotational speed of the generator means beyond that of the axle, and management control means to selectively direct electrical power from the generator means to either the motor for power or the batteries for recharge, depending upon the driving conditions and requirements.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
92 words
An electrically powered vehicle comprising two axles connected to wheels, an electric motor coupled to one said axle to drive said vehicle, generator means coupled to the other said axle whereby the rotation of said axle powers said generator means to create electricity, rechargeable batteries to supply electricity to said motor, electrical conducting means connecting said motor, said generator means and said batteries, and management control means to selectively deliver electricity from said batteries to said motor or from said generator means to either said motor or to said batteries for recharge.
Claim 2
Dependent Claim
92 words
An electrically powered vehicle comprising two axles connected to wheels, an electric motor coupled to one said axle to drive said vehicle, generator means coupled to the other said axle whereby the rotation of said axle powers said generator means to create electricity, rechargeable batteries to supply electricity to said motor, electrical conducting means connecting said motor, said generator means and said batteries, and management control means to selectively deliver electricity from said batteries to said motor or from said generator means to either said motor or to said batteries for recharge.
Claim 3
Dependent Claim
39 words
The vehicle of claim 1, further comprising transmission gearing means coupled between said axle and said generator means whereby the rotation speed of said generator means may be increased to greater speed than the rotation speed of said axle.
Claim 4
Dependent Claim
154 words
An electrically powered vehicle comprising a plural number of rotating axles connected to wheels, at least one electric motor connected to at least one said axle to drive said vehicle, at least one generator means coupled to at least one said axle whereby the rotation of at least one said axle powers said at least one generator means to create electricity, rechargeable batteries to supply electricity to said at least one motor, electrical conducting means connecting said at least one motor, said at least one generator and said batteries, transmission gearing means coupled to said at least one generator means to increase the rotation speed of said at least one generator means to a speed greater than the speed of said at least one axle, and management control means to selectively deliver electricity from said batteries to said motor or from said generator means to either said motor or to said batteries for recharge.
Claim 5
Dependent Claim
154 words
An electrically powered vehicle comprising a plural number of rotating axles connected to wheels, at least one electric motor connected to at least one said axle to drive said vehicle, at least one generator means coupled to at least one said axle whereby the rotation of at least one said axle powers said at least one generator means to create electricity, rechargeable batteries to supply electricity to said at least one motor, electrical conducting means connecting said at least one motor, said at least one generator and said batteries, transmission gearing means coupled to said at least one generator means to increase the rotation speed of said at least one generator means to a speed greater than the speed of said at least one axle, and management control means to selectively deliver electricity from said batteries to said motor or from said generator means to either said motor or to said batteries for recharge.
Claim 6
Dependent Claim
14 words
The vehicle of claim 3, comprising four said motors and one said generator means.
Claim 7
Dependent Claim
14 words
The vehicle of claim 3, comprising four said generator means and one said motor.
Claim 8
Dependent Claim
18 words
The vehicle of claim 3, where said generator means and said motor are connected coaxially to said axles.
Claim 9
Dependent Claim
15 words
The vehicle of claim 3, comprising four independent axles, two generator means and two motors.
Claim 10
Dependent Claim
15 words
The vehicle of claim 3, comprising four independent axles, four generator means and four motors.
