Can a plug-in hybrid run without charging all the time?

Plug-in hybrid cannot run without charging all the time. Plug-in hybrid electric vehicle (PHEV) is a type of vehicle between an electric vehicle and a fuel vehicle, equipped with both the engine, transmission, drive system, fuel line, and fuel tank of a traditional fuel vehicle, as well as the battery, motor, and control circuit of an electric vehicle. The battery capacity can also support driving in pure electric mode for a certain distance and provides a charging interface. Plug-in hybrid vehicles will not run out of power while driving. If there are charging piles nearby, they can be driven as an electric vehicle. When driving a plug-in hybrid vehicle, it can operate in pure electric mode or hybrid mode. In the battery hold mode, the vehicle is also in hybrid mode, similar to a regular hybrid vehicle. It starts in pure electric mode, the engine intervenes when speed increases, and kinetic energy is recovered during coasting and braking.
I've been driving a plug-in hybrid for over three years. While theoretically it's possible to never charge it and just run on gasoline mode, I must say that's really not cost-effective. For daily commutes using pure electric mode for 30-40 kilometers, fuel consumption is basically zero. But once when I was on a business trip for a month without charging, relying solely on the engine, fuel consumption skyrocketed to over 7 liters per 100km – higher than a regular gasoline car. The key issue is that prolonged lack of charging causes battery degradation, reducing electric driving range and weakening power output. So I recommend charging at least once a week – installing a simple home charging station isn't troublesome. These vehicles are designed as hybrids; proper charging is needed to realize their fuel-saving and eco-friendly advantages. While long-term non-charging is technically possible, it results in poor experience and hurts your wallet – truly unnecessary.
From a technical perspective, plug-in hybrid vehicles are quite intelligent in their systems. The engine can generate electricity to replenish the battery at any time, allowing unlimited driving even without charging. However, there is a cost to this: the engine may be overworked, leading to increased fuel consumption; if the battery remains at low charge for extended periods, its cycle life could be compromised, potentially resulting in high battery replacement costs after a few years. Based on my experience, occasionally using hybrid mode on highways is acceptable, but for daily urban commuting, it's best to charge the vehicle. Essentially, this car is a fuel-saving tool, and not charging it wastes its advantages. Consider the rising gasoline prices—stable electricity costs offer more savings. If used purely as a gasoline car, a traditional hybrid would be more economical. The core value of a plug-in hybrid lies in its flexible charging capability.
I originally bought a plug-in hybrid for environmental reasons, to reduce carbon emissions. If you never charge it and rely solely on gasoline, pollution emissions will increase significantly. Charging maximizes the electric driving mode, allowing for zero-emission driving for dozens of kilometers in the city. By sticking to charging once a week, fuel consumption drops, and the carbon footprint becomes much smaller. Not charging for a long time isn't prohibited, but it goes against the concept of sustainable development. My neighbor treats their plug-in hybrid like a pure gasoline car, not only resulting in high fuel consumption but also frequently complaining about the lack of power. This type of car requires proper battery maintenance—charging is like resting after exercise. A simple small habit can protect the planet and save money.
