The principle of BYD plug-in hybrid fuel saving can be summarized as follows:
1. Electric motor and internal combustion engine work together: Plug in hybrid vehicles combine two power sources: electric motor and internal combustion engine. When the vehicle is starting, driving at low speeds, or requires less power, the electric motor works independently to provide power and reduce fuel consumption. When the vehicle requires higher power output, such as acceleration or climbing, the internal combustion engine will start and provide additional power, while the electric motor can also assist in the work, making the power output smoother and improving overall efficiency.
2. Intelligent energy management system: BYD plug-in hybrid models are equipped with advanced energy management systems that can monitor the vehicle's driving status and energy consumption in real time. According to actual driving needs, the system will automatically adjust the working status of the internal combustion engine and electric motor to achieve optimal energy utilization efficiency. For example, when the vehicle is driving steadily, some of the power from the internal combustion engine will drive the electric motor to generate electricity and charge the battery system, thereby improving energy utilization efficiency.
3. Multiple driving modes and efficient battery system: BYD plug-in hybrid models offer multiple driving modes, such as pure electric mode, hybrid mode, and high-performance mode. In pure electric mode, the vehicle relies entirely on the battery system to achieve zero fuel consumption driving. An efficient battery system can provide stable power support for electric motors during vehicle operation and quickly store electrical energy during parking and charging. This not only extends the vehicle's range, but also improves overall energy efficiency. By setting the SOC value reasonably and utilizing charging facilities to charge the battery in a timely manner, it can ensure that the vehicle has sufficient energy reserves when needed, thereby further reducing fuel consumption.
The principle of BYD plug-in hybrid fuel saving is mainly due to the collaborative work of electric motors and internal combustion engines, the application of intelligent energy management systems, and the support of multiple driving modes and efficient battery systems. Under the combined effect of these technological features, BYD plug-in hybrid models have achieved lower fuel consumption levels while maintaining strong power.
