What is the Principle of Hybrid Power?

The following is an introduction to the principle of hybrid power and related information about hybrid vehicles: 1. Principle of Hybrid Power: The principle of hybrid power involves the combination of a traditional gasoline engine and an electric motor to output power. The engine's operation is used to charge the battery, and the power generated by the car's electric motor and engine is continuously switched and converted. 2. Hybrid Power: Based on the degree of dependence on electric energy, hybrid power can be divided into Mild Hybrid (also known as light hybrid, soft hybrid, micro hybrid, etc.), Moderate Hybrid, Full Hybrid (also known as strong hybrid, etc.), and Plug-in Hybrid.
The hybrid principle is actually quite like teamwork. The engine and electric motor take turns or work together, complementing each other's weaknesses. For example, during low-speed traffic jams, the electric motor drives alone, running quietly and saving fuel; during acceleration or overtaking, both work together to deliver strong push-back force; during high-speed cruising, the engine takes the lead due to its efficiency, with excess energy charging the battery. My hybrid car operates this way meticulously, and the dashboard shows real-time energy flow mode switches, with city commuting fuel consumption just over 5 liters. What surprised me most is the kinetic energy recovery during deceleration, making the brake pads last much longer than in fuel-powered cars.
The essence of hybrid technology lies in the intelligent switching between gasoline and electric power. At its core is a planetary gearset that acts as a coordinator, with the engine driving a generator to produce electricity, which then powers the electric motor or is stored in the battery. During slow urban driving, it operates purely on electricity for quiet and eco-friendly performance. When rapid acceleration is needed, the battery pack provides additional torque. For high-speed cruising, the engine directly drives the wheels for optimal fuel efficiency. Energy is automatically recovered during downhill braking, and the battery maintains a buffer of around 30% charge. In winter, the system uses electric heating for immediate warmth without waiting for the engine to warm up. Having disassembled and repaired this system, I can confirm it indeed requires three additional cooling systems compared to conventional gasoline vehicles to manage the electric motor and battery.
