What is the difference between plug-in cars and hybrid cars?

[LukeFitz]

Plug-in cars not only require refueling but also need to be charged. On the other hand, hybrid cars, like conventional fuel vehicles, only need to be refueled. The main differences between plug-in cars and hybrid cars are as follows: 1. The electricity in hybrid models is generated by charging the battery during steady-speed driving, slow driving, and braking deceleration. The battery in hybrid models is much smaller, typically only capable of ensuring about 3 kilometers of driving in pure electric mode. Its electricity is mainly used to supplement the engine power during rapid acceleration with heavy throttle, keeping the engine in the most fuel-efficient state, as well as in stop-and-go traffic congestion. 2. The battery in plug-in hybrid models is much larger, usually capable of ensuring about 60 kilometers of driving in pure electric mode. Compared to hybrid models, they are closer to pure electric vehicles. The source of their electricity, besides the same methods as hybrid models, also includes direct external charging of the battery. Plug-in hybrids consume more fuel than conventional fuel vehicles in pure fuel mode and more electricity than electric vehicles in pure electric mode.
