How to turn a motor into a generator and use it to charge a car battery?

Did you know that you can save fuel and run your car on water
lethaldriver questioned:
I am preparation to build an gripping vehicle and I want to have regenerative brakes to boost its travel array.
Some public say that a motor and a generator are in the end the same business.
But how come a car alternator doesn’t turn on its own even when it’s collectively to a car battery?
I plot to potential the gripping motor with four 12volt batteries collectively in run to make a total of 48volts.
What must I do to be able to straight away convert the motor into a generator (to convert kinetic into electrical energy and payment
the batteries) as the vehicle is in budge?
is here a need for some complicated circuit boards to do this?
if I were able to batter the clear and unenthusiastic relations to the motor as the vehicle is tender then would it payment the batteries?

A generator produces DC current
a alternator produces AC current that is converted to DC current that is usable in automotive applications
The unadorned pledge is “Yes”, you need some complicated circuitry to make the potential flow in the much loved management upon command.
Both ac apparatus and dc apparatus can be used as motors or generators below the right conditions.
An alternator is in the end a established pull AC generator with a diode join at the productivity, so potential only flows OUT of its terminals. That’s why it won’t motor.
A fixed squirrel cage induction motor can be used as a generator, if here is an outdoor ac source to grant the de rigueur excitation, and the outdoor fill in transporter rotates closer than synchronous speed. Huge wind turbines often use this deal with.
To do what you want for automotive applications, you need a potential electronic converter that can chat the voltages on the glide to supervise over potential any into the apparatus (as a motor), or out of the apparatus (as a generator). Note that this is very uncommon from just unreliable the polarity between battery and motor.
If you only batter the helpful polarity, the motor just tries to promptly chat to spinning in the contrary management. This facility for braking, but puts a LOT of heat into the motor. Potential is subdue flowing from battery to motor, and no re-age assemble occurs.
yes any generator can operates as motor and vis versa
but u can’t acheive this thought
as in order to make the motor operates as a generator to give the batteries
