Is It An EREV Or PHEV?

Is It An EREV Or PHEV?

It's unlikely that the EREV or PHEV battle will ever come to an end, but recently the Society Of Automotive Engineers provided a definition for both classes of vehicles in a paper title “Chevrolet Volt Electric Utilization.

Here are the SAE-provided definitions:

E-REV: “A vehicle that functions as full-performance battery electric vehicle when energy is available from an onboard RESS and having an auxiliary energy supply that is only engaged when the RESS energy is not available.”

PHEV: “A hybrid vehicle with the ability to store and use off-board electrical energy in the RESS.”

So, where does the first-gen Volt fit in? Should the next-gen Volt be classified differently?  BMW i3 REx?  What classification does it get?
