Oh boy, where do I even start.
Step 1: lean about thermodynamics.
Step 2: learn about regenerative braking
Step 3: apologize to the internet for your confident ignorance.

I will NOT apologize for thing I barely understand!
And then there's this: it looks like a standard car alternator that puts out around 14.5 volts. That's way, way, way below what an EV battery pack needs to charge. So there would be need for a step-up converter, which would introduce losses, and further decrease the range, on top of the already abysmal efficiency of a car alternator!
The energy the generator would use to charge the battery with comes from the wheel, which in turn gets its energy from the motor and the motor is powered by the battery. It's a loop but since every step of conversion (battery to motor to wheel to generator to battery) causes a loss through friction and electrical resistance it's a net loss.
If it wasn't you could hook generators to motors with a battery in between and just give it an initial spin to create a perpetual motion machine.
It's the conservation of energy. You can't create anything from nothing or destroy it to nothing, you can only change it to different things.
Personally I was really annoyed at realizing this as a child. Really put a crimp in a lot of my ideas.
