The definition and characteristics of hybrid vehicles, also known as hybrid electric vehicles, can be summarized as follows:
1. Definition: Hybrid vehicles refer to vehicles that have two or more power sources simultaneously, also known as hybrid vehicles. It combines two power sources, fuel and electricity, and provides power to the vehicle through different drive systems, either jointly or separately.
2. Power combination: Hybrid cars are usually equipped with internal combustion engines, electric motors, and related battery packs. In some car models, auxiliary power sources such as fuel cells or solar cells may also be included. Internal combustion engines are primarily responsible for providing power during high-speed driving or when high power output is required, while electric motors play a major role during low-speed driving, acceleration at start-up, or energy recovery.
3. Working principle and advantages: Hybrid vehicles can flexibly adjust the power output of internal combustion engines and electric motors according to actual driving conditions and needs, in order to achieve higher energy efficiency and environmental performance. During low-speed driving and starting, the electric motor can provide smoother and quieter power output, while reducing the load and emissions of the internal combustion engine. When driving at high speeds, internal combustion engines can leverage their high efficiency and high power advantages to provide continuous power support for vehicles. Hybrid vehicles also have an energy recovery system that can convert kinetic energy into electrical energy during braking or deceleration and store it in the battery, further improving energy utilization efficiency.
Hybrid vehicles are a type of vehicle that combines multiple power sources such as internal combustion engines and electric motors. By optimizing the power combination and working principle, they achieve higher energy efficiency and environmental performance.
