I got a wild idea to convert my old Honda Civic into electric car, remove
engine and install dc motor with good torque and deep cycle battery bank
(like golf cart batteries) to power dc motor. Also install a battery
charger in car for charging batteries while parked over night in garage or
any other place where AC outlet is available.

I am also thinking to have a small diesel generator in car to charge
batteries in case on long drive.

Now back to DC motor..... I am lookin a motor something like half motor and
half generator. When motor is in use for driving, the other half side of the
motor is also generating electric to charge the batteries same time
.......Got the idea ? Now this kinda motor is special, not a normal motor,
any one knows or any info on that kinda motor ?

I know lot of genius and more knowledgeable peoples are here, I would
appreciate some input on this project or from any one who has done something
similar to this project.

Something like the following:

You might have to remove a couple of seats or something to fit that
"small" generator. It might help if it was a high speed rotary
diesel with a turbo. They are slightly smaller and lighter if they
exist at all.

Regenerative braking, where you run the motor as a generator to recharge
the batteries, uses all of the motor. It's either operating entirely as
a motor and pushing the car down the road or operating entirely as a
generator and slowing the car.

If you're looking for some magic perpetual motion device (which produces
more electricity than it uses) then you're out of luck. No such thing
can exist in this universe unless someone rewrites the laws of physics.

There are kits for the honda civic. Google it

Put the diesel on a trailer so you don't have to drag around the extra
weight when running short distances

Can not be done. At least not with any good results.
You CAN have the motor act as a generator when decellerating
(regenerative braking) with the right controller.
I know lot of genius and more knowledgeable peoples are here, I would
appreciate some input on this project or from any one who has done something
similar to this project.
I "did" a '75 Fiat 128L coupe back about 1978. I had a very
rudimentary controller, an aircraft generator for a motor, and 8 6
volt golf cart batteries (GC2H - 235 amp hour). Good for 50 miles at
30mph, or 30 miles at 50 on a charge.
 
A motor that simultaneously generates torque and charges batteries cannot be
made; it is contrary to the laws of physics.
There do exist motors that can generate electric power while exerting a
braking action on the car.

But you can't have torque generation and power generation at the same time.

A general comment: Since making a practical electric car has taken billions
in research by the major car manufacturers, it is too hard for you to do
well. You would end up with a car that had a very low power to weight ratio.
Ie., it would be very slow, and it would probably have very little usable
space.

Don't bother.
My Fiat was a full 4 passenger car and could strip the rubber off the
front tires with very little effort. The motor was small for the
application, but I ran the 4 speed transmission. Top speed was in
excess of 50mph.

I think you are referring to braking regeneration, allowing some of the
energy dissipated in braking to flow back to the batteries. Most modern
controllers have this function. See the Curtis site.

otherwise there is no energy for "charging" the batteries, as your
"generator" would just draw more power from the batteries to run it.
