Am I misinterpreting this?
Also a Boost converter is not a Voltage Multiplier device. An alternator produces AC. A Voltage Multiplier device converts AC to DC and multiplies the DC Voltage many times.
We are not changing the closed system's energy, we are converting its output to a higher Voltage which would be higher than the DC drain on the battery. (Theoretically assuming all factors are considered properly)

Truly closed systems, without interference, exist only in theory. Anything you actually build, is going to suffer interference, even if you just made a motor that powered an alternator, that powered the motor. There are no truly frictionless materials, no alternators or motors that don't create some heat, and no wires without some resistance to connect them. This is before we actually move the car, or turn on a light.
I'm no electrical engineer, but I had to take a lot of their classes while working on a physics degree.
I promise you that a self charging car, never needing charging or fuel is not possible at all.
