What is the Difference Between Range-Extended Hybrid and Plug-in Hybrid?

[Isaac]

Range-extended hybrid and plug-in hybrid differ in nature, power, and characteristics. Each has its own advantages and disadvantages. The specific details are as follows: Different in nature: A range-extended hybrid uses the power battery to drive the motor and propel the vehicle, with the engine only charging the power battery and not directly providing power. In contrast, a plug-in hybrid can directly use the engine for power when the vehicle's battery is low. Different in power: In a range-extended hybrid, when the battery is sufficiently charged, the power battery directly drives the motor to meet the vehicle's power demand, and the engine does not participate in operation. A plug-in hybrid relies on the power battery for propulsion when the battery is sufficiently charged, offering a longer pure electric range. When the battery is low, the engine starts and uses traditional engine power to continue driving. Different in characteristics: The disadvantage of non-plug-in hybrid vehicles is their very short pure electric range. In China, they are not classified as new energy vehicles, so they cannot enjoy new energy vehicle subsidy policies or obtain the exclusive green license plates for new energy vehicles. Since the engine in a range-extended hybrid can only be used for generating electricity, it never achieves optimal working efficiency, resulting in higher fuel consumption.
