"Extended-range electric vehicles, or EREVs, promise all the benefits of regular EVsbut without the range anxiety or charging concerns. That's thanks to a combustion engine that acts solely as a generator for the electric powertrain. An EREV is an electric car at heart, but there's also a combustion engine that turns a generator to replenish the battery on the go. There's no mechanical connection between the engine and wheels, though."
"Long lines at the fast chargers? No problem. There's no destination charger at the hotel? No problem, just fill up the tank at the friendly local gas station and let the generator, which can't drive the wheels directly, feed the battery. If efficiency and lower emissions tickle your fancy, EREVs can also be fast-charged like a regular EV. At least, that's the promise; as with conventional plug-in hybrids, there's no guarantee that people will actually plug in these cars."
Extended-range electric vehicles (EREVs) pair an electric powertrain with a combustion engine that functions solely as an onboard generator, with no mechanical connection to the wheels. Drivers can rely on electric driving while using the engine to recharge the battery on the go, eliminating range anxiety and enabling refueling at conventional gas stations. EREVs can also accept fast charging like conventional EVs, offering flexibility. Real-world charging behavior may vary, and drivers might not always plug in. The EREV concept has prior examples in the U.S. and is attracting renewed interest as automakers adjust plans amid public and regulatory hesitancy toward pure EVs. The Ram 1500 REV is a forthcoming extended-range pickup.
