Abstract
Abstract There is disclosed an energy regenerating mechanism of an automobile, particularly to that adapted for an electric car. The energy regenerating mechanism is characterized in that a plurality of generators are provided so that the kinetic energy generated when the engine idles and the automobile continues running is converted into electric energy.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
148 words
An electric automobile comprising: a chassis; front and rear wheels supporting said chassis for movement; electric motors drivingly connected to said wheels for rotating said wheels, said motors being free from mechanical connection to each other; a battery connected in parallel to said electric motors for supplying electrical energy for operating said electric motors; separate electricity generators each drivingly connected to one of said wheels for transforming into electrical energy the kinetic energy of said automobile while said motors are not driving said wheels, each of said generators being free of electrical connection to its associated motor; conductors connecting said generators in parallel to said battery for supplying said electrical energy for charging said battery; and means for turning off said generators when said motors are driving said wheels and for turning on said generators when said automobile is moving and sad motors are not driving said wheels.
Claim 2
Dependent Claim
148 words
An electric automobile comprising: a chassis; front and rear wheels supporting said chassis for movement; electric motors drivingly connected to said wheels for rotating said wheels, said motors being free from mechanical connection to each other; a battery connected in parallel to said electric motors for supplying electrical energy for operating said electric motors; separate electricity generators each drivingly connected to one of said wheels for transforming into electrical energy the kinetic energy of said automobile while said motors are not driving said wheels, each of said generators being free of electrical connection to its associated motor; conductors connecting said generators in parallel to said battery for supplying said electrical energy for charging said battery; and means for turning off said generators when said motors are driving said wheels and for turning on said generators when said automobile is moving and sad motors are not driving said wheels.
