Can Hybrid Cars Run on Electricity Only?

Hybrid cars can indeed run on electricity alone. Hybrid vehicles can be categorized into three types: plug-in hybrid, conventional hybrid, and range-extended hybrid. Below is a detailed introduction: Plug-in Hybrid Electric Vehicles (PHEVs): PHEVs have relatively larger batteries that can be charged externally. They can operate in pure electric mode until the battery is depleted, after which they switch to hybrid mode (primarily using the internal combustion engine) while simultaneously charging the battery. Common PHEV models include the Roewe eRX5, Trumpchi GA5, and Trumpchi GS4. Conventional Hybrid Electric Vehicles (HEVs): Due to their smaller battery capacity, HEVs primarily rely on the battery for energy recovery during starting, stopping, acceleration, or deceleration, and cannot travel long distances in pure electric mode. This is a well-established type of hybrid vehicle, with models like the Corolla Hybrid, Camry Hybrid, and Accord Hybrid utilizing this technology. Range-Extended Hybrid Electric Vehicles (REEVs): REEVs operate by using an engine to generate electricity that powers the electric motor for propulsion. When the battery is sufficiently charged, the vehicle runs in pure electric mode. When the battery is low, the onboard engine starts to drive a generator, which charges the battery to provide power for the electric motor (i.e., range-extending mode). Unlike PHEVs and HEVs, REEVs cannot be directly driven by the engine under any circumstances; they rely solely on the electric motor for propulsion. However, like PHEVs, they can also be charged via an external power source.
I've been driving a hybrid for several years, and this is a very practical question. Whether a hybrid can run on electricity alone depends on the specific model. For plug-in hybrids (PHEVs), like some BYD models, there's usually a pure electric mode option. After a full charge, you can drive dozens of kilometers in the city using only electricity, without the engine—quiet and cost-effective, ideal for traffic jams. However, for regular hybrids like the Toyota Prius, the small battery means the engine always assists, especially during acceleration or at high speeds, making it nearly impossible to drive purely on electricity. From my experience, I recommend checking the vehicle manual or testing the pure electric function before purchasing to avoid misunderstandings. PHEVs can save on fuel costs and are more environmentally friendly.
