What are the types of hybrid vehicles?

Hybrid vehicles can be categorized into three types based on the configuration of their power drive systems: series hybrid, parallel hybrid, and series-parallel hybrid. More details are as follows: 1. A hybrid vehicle refers to a vehicle whose drive system consists of two or more individual drive systems that can operate simultaneously. Typically, the term hybrid vehicle refers to gasoline-electric hybrid vehicles. As environmental protection regulations become increasingly stringent worldwide, hybrid vehicles have become a focus of automotive research and development due to their energy-saving and low-emission characteristics. 2. In a series hybrid, the engine, generator, and drive motor are connected in series to form the drive system. The engine charges the battery, which is then connected in series with the motor, ultimately driving the vehicle. This configuration is more common in medium and large-sized vehicles. In a parallel hybrid, the engine and generator are connected in parallel, allowing their driving forces to be combined or output separately. 3. The series-parallel hybrid combines the advantages of both series and parallel systems. It operates in series hybrid mode at low speeds and switches to parallel hybrid mode at high speeds. However, the downside is that the technology is more complex than the other two types, resulting in higher costs.
I see that hybrid vehicles are mainly divided into several types: The first is parallel hybrid, where the engine and electric motor can drive the wheels together or separately. Many Honda vehicles use this system, which offers strong power but may not be as fuel-efficient. The second is series hybrid, where the engine only generates electricity and does not directly drive the wheels, relying on the electric motor for propulsion. Extended-range electric vehicles like those from Li Auto are typical examples, known for their quiet operation and high efficiency. The third is power-split hybrid, which combines the advantages of parallel and series hybrids. Toyota's THS technology, for instance, uses planetary gears to coordinate and balance power and fuel efficiency. The fourth is plug-in hybrid (PHEV), which can be charged externally and offers a pure electric range of several dozen kilometers. The BYD DM-i series is very popular, making it ideal for cost-effective urban commuting. The fifth is mild hybrid (HEV), which does not require charging but significantly improves fuel efficiency. The Toyota Corolla Hybrid is a common example. These classifications stem from different powertrain designs, affecting driving experience and costs. I recommend choosing a vehicle based on driving habits and charging conditions, avoiding the pitfall of prioritizing new technology over practicality.
From the owner's perspective, hybrid vehicles can be categorized into several types: conventional hybrids that don't require charging, where the electric motor assists the engine to save fuel, making them ideal for daily commutes; plug-in hybrids (PHEV) that can be charged externally, featuring larger batteries capable of driving dozens of kilometers on pure electric power, like the BYD Tang—cost-effective but with the hassle of charging; range-extended electric vehicles where the engine only generates electricity to power the motor, offering quiet operation and simple maintenance, with the Li L9 being a prime example. There are also series-parallel hybrids that balance performance and efficiency, represented by the Toyota Prius. Having driven these vehicles, I can say the type of hybrid affects usage costs—plug-ins are more economical in the long run but pricier upfront; for frequent long-distance travel, conventional hybrids are more reliable. The key is to consider personal budget and lifestyle rather than blindly following trends.
