Can you share some examples?

To my understanding EREV, like the i3 pictured in models with the optional ICE, is mostly driven on battery power with the generator as a backup. It doesn’t even provide full power when running on the generator whilst the battery is low. I don’t know of examples of EREV without a battery or with a tiny battery which would be classified as EREV but would like to see examples. I know of some studies showing lowered fuel consumption but nothing for consumers.

I would understand your frustration towards EREV in the cases where it’s mainly burning fuel as that’s indeed not BEV at all.

Did not look thus up, do verify if necessary.

EREV is a BEV with a backup engine. PHEV is mainly a combustion engine vehicle with a limited electric drivetrain bolted on.

EREV powers a generator to drive the electric drivetrain. The electric drivetrain is the only drivetrain and must thus provide the full functionality. The intent is to drive fully electric and have an emergency backup. Markets place maxima on the amount of fuel the fuel tank may carry in some markets (eg: 10L).

PHEV has the dino burning engine drive the wheels and an electric drivetrain. The battery can be charged. The electric drivetrain often doesn’t provide the full functionality (eg: it has too limited power and and may be limited to low speeds).
