A regular car alternator can generate way less than that.
At 500 Watt 15 seconds would yield just 7500 Joule, just enough to power a 150 Watt system for 50 seconds.
I bet the belt drag alone would annihilate that gain in most situations.

I have a pair of cars with regenerative alternators.
My 0.9l two cylinder engine's alt has been ramped up- all the way to 120A! That's 1680 watts
The limiting factor is the batteries charge acceptance.
