What are the types of hybrid vehicles?
1 Answers
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.
