What is the Detailed Explanation of Hybrid Vehicle Principles?

The following is a detailed explanation of hybrid vehicle principles: 1. At the beginning of vehicle operation, the battery is in a fully charged state, and its energy output can meet the vehicle's requirements, so the auxiliary power system does not need to work. 2. When the battery level drops below 60%, the auxiliary power system starts: when the vehicle's energy demand is high, the auxiliary power system and the battery pack simultaneously provide energy to the drive system; when the vehicle's energy demand is low, the auxiliary power system not only supplies energy to the drive system but also charges the battery pack. 3. Due to the presence of the battery pack, the engine operates under relatively stable conditions, thereby improving its emissions.
When I used to drive a hybrid car, I found its working principle quite fascinating. Simply put, it combines a gasoline engine with an electric motor to work together. The car primarily relies on the electric motor for starting and low-speed driving because the motor can deliver instant torque, which means the gasoline engine doesn’t have to work as much, saving a lot of fuel. When you brake or release the accelerator, the system converts kinetic energy into electricity and stores it in the battery—this is called regenerative braking, preventing energy waste. During high-speed driving, the gasoline engine takes over and simultaneously charges the battery. The entire process is intelligently managed by a control computer, which automatically switches power sources to ensure smooth and efficient driving. This design not only makes hybrid cars fuel-efficient and hassle-free but also reduces exhaust emissions, making them more environmentally friendly. As a long-term driver, I always felt like there was an invisible assistant optimizing everything while driving.
