The 'hidden source of power' on hybrids and EVs

We often forget that there is a sort of 'fourth force' at play in hybrids and electric vehicles.

Yes, there is the battery, electric motor and the (usually petrol) engine as you know.

But one element often overlooked (especially by me) is the 'feedback' power of regeneration.

This happens particularly when you apply the brakes - the energy flow is reversed and converted to its electrical source.

The same happens when you lift off the accelerator.

Anyone who has driven, or been in, a hybrid will no doubt have seen the flowing graphic representation of this on the screen. It's fascinating.

I mention this in connection with our report from last week on the results of a UCD study into how far hybrids go on electric power.

Strictly speaking I should have mentioned and accounted for regeneration which, no doubt, added to the length of time the petrol engine, for one, was not in use.

I don't know about you, but I think there is something quite special about the whole idea of being able to turn slowing-down-energy to such good use.
