Nope. The ecu senses when the engine has surplus power and uses this

And when the battery is fully charged, what happens to this 'surplus

Senile one, the engine revs down and the electric motor cuts in. Duh!

So the 'power' it was generating wasn't surplus?

It was by the IC engines. It was captured and given back off.
