The core components of DM-i technology include an efficient electric motor, plug-in hybrid battery pack and efficient internal combustion engine. The system adopts the EHS electric hybrid system architecture, which can realize intelligent switching of multiple power modes, including pure electric mode, hybrid mode and engine direct drive mode. When driving at low speeds and in urban areas, the vehicle relies more on electric motors to drive, thereby reducing fuel consumption and emissions; when driving at high speeds, the engine can directly drive the wheels to improve fuel efficiency.
In terms of energy management, the DM-i system has advanced energy recovery functions, which can recover and store kinetic energy in the battery during deceleration or braking, thereby further improving the energy efficiency of the entire vehicle. In addition, the plug-in design allows the vehicle to be charged externally, supporting pure electric cruising range, meeting the needs of users for daily short-distance travel, while also avoiding the range anxiety of traditional fuel vehicles.
The internal combustion engine used in DM-i technology has been specially optimized to achieve higher thermal efficiency and better fuel economy than traditional engines. This combination of a high-efficiency internal combustion engine and a powerful electric motor enables the vehicle to perform well during acceleration and provide smooth and powerful power delivery.
In addition, DM-i technology also focuses on smoothness and quietness of driving. Since it is mainly driven by electric motors at low speeds, the noise and vibration of the vehicle are greatly reduced, resulting in a more comfortable driving experience. At the same time, the system's intelligent energy management makes switching between different driving modes almost seamless, further improving the smoothness of driving.
In general, BYD's DM-i super hybrid technology uses an ingenious combination of electric drive and internal combustion engines to significantly improve fuel efficiency and reduce emissions while maintaining strong power. It is BYD's first step in the field of new energy vehicles. An important innovation that marks the future development direction of hybrid vehicles.
