What is the meaning of hybrid vehicles?

Hybrid vehicles (also known as hybrid-electric vehicles, referred to as Hybrid-Power-Automobile in English) are equipped with two or more power sources: storage batteries, fuel cells, solar cells, and the generator sets of internal combustion engine vehicles. Currently, hybrid vehicles generally refer to those that combine an internal combustion engine generator with a storage battery. There are currently three main types of hybrid vehicles: 1. The "parallel hybrid" system, where the engine serves as the main power source and the electric motor acts as an auxiliary power source. In this setup, the vehicle is primarily driven by the engine, while the electric motor, which can generate strong power during startup, assists during acceleration or when the engine's fuel consumption is high, thereby reducing the engine's fuel consumption. 2. The "series-parallel hybrid" system, where the vehicle is driven solely by the electric motor at low speeds, and the engine and electric motor work together at higher speeds. During startup and at low speeds, the vehicle is powered only by the electric motor. As speed increases, the engine and electric motor efficiently share the power load. 3. The "series hybrid" system, which is essentially an electric vehicle driven solely by the electric motor. The engine only serves as a power source, and the vehicle is driven exclusively by the electric motor. Although the drive system consists only of the electric motor, because it still requires a fuel engine, it is also considered a type of hybrid vehicle.
Hybrid cars are those magical vehicles that don't need charging but are more fuel-efficient than traditional gasoline cars. I've deeply experienced this with my Corolla Hybrid. It comes with both an engine and a small electric motor, charging by recovering energy during braking. It's eerily quiet in low-speed traffic jams, and automatically switches to gasoline mode on highways. Unlike pure electric cars with range anxiety, you don't need to hunt for charging stations everywhere - just refuel and go. Last week I took a long trip with only 4.2L/100km fuel consumption, saving nearly half the fuel costs compared to my neighbor's same-class gasoline car.
