Abstract

An electrical system to provide a continuous source of energy AC/DC within a vehicle. This system charges the batteries thus exerting a natural braking effect on the motor at those times when it is desired to slow the forward motion of the vehicle such as when going down hill or needing to come to a stop. Due to the batteries being thus intermittently charged, somewhat smaller batteries may be used than are used in the prior art, and the recharging interval can be lengthened. The system is environmentally friendly, with zero emissions and is economical to operate. In addition, the vehicle is quiet and gives a smooth ride.

Claims

1. An electrical charging and driving system for an electric powered vehicle, comprising:

a) at least one battery;

b) at least one motor powered by said battery, said motor connected directly to a rear axle of said vehicle;

c) a front axle of said vehicle having a belt;

d) rear wheels rotatively turned by said motor through the rear axle;

e) generating means for converting the rotatable turning of the front axle into electrical current, said generating means having a pulley;

f) generator engaging means for enabling the belt on the front axle to engage the pulley of the generating means, whereby the pulley may be rotatably turned by the belt on the front axle;

g) acceleration means for accelerating the vehicle, said acceleration means comprising an acceleration applied state and an acceleration nonapplied state;

h) braking means for retarding the forward movement of the vehicle, said braking means comprising a braking applied state and a braking nonapplied state;

i) means comprising a single charging system responsive to acceleration means and braking means for causing the generator engaging means to enable the belt on the front axle to engage the pulley of the generating means, whenever the acceleration means is in the acceleration nonapplied state or the braking means is in the braking applied state;

j) means for using the current from the generating means to charge the battery; and

k) a cooling system in said vehicle comprising a blower in a front of said vehicle for blowing air to said motor and said generator, and having a fan for directing some heat into an interior of said vehicle.

2. The electrical charging and driving system of claim 1, wherein the motor is a brushless motor, said motor being reversible.

3. The electrical charging and driving system of claim 2, wherein the generating means is an AC generator, said AC generator being reversible.

4. An electrical charging and driving system for an electric powered vehicle, comprising:

a) front wheels and rear wheels in said vehicle;

b) each of said rear wheels having an axle with a reversible AC/DC motor mounted thereon and positraction for driving said rear wheels;

c) a bank of batteries mounted in a rear portion of said vehicle;

d) a special panel mounted in a forward section of said vehicle adjacent a side body panel thereof;

e) electrical cables connecting said bank of batteries to said special panel for receiving and sending power to said bank of batteries;

f) a first cable for delivering electrical power to said reversible AC/DC motors from said special panel;

g) a reversible AC generator mounted in a forward portion of said vehicle, said AC generator having a pulley connected thereto;

h) a second cable for delivering electric power from said AC generator to said special panel when said AC generator is driven;

i) a front axle connected to said front wheels;

j) a driving belt fixedly attached to said front axle;

k) said vehicle having an accelerator pedal for transferring electric power from said bank of batteries to said special panel which converts DC power received to AC power for delivery over said first cable to said reversible AC/DC motors to drive said rear wheels;

l) said vehicle having a brake pedal for slowing down said vehicle;

m) a single charging system comprising means for connecting said belt to said pulley to drive said AC generator when a driver releases a foot from the accelerator pedal or said driver presses said brake pedal for delivering AC electrical power to said special panel over said second cable, said special panel converting power received to DC and transferring said DC over said electrical cables to said bank of batteries for recharging said batteries;

n) a cooling system in said vehicle comprising a blower in a front of said vehicle for blowing air to said AC/DC motors and said AC generator, and having a fan for directing some heat into an interior of said vehicle; and

o) said vehicle having a control system in which wheel speed and objective speed set point are compared using a software error reducing algorithm to optimize achievement of the objective speed test point.
