What are the differences between BYD Han DM and DM-i?
1 Answers
The differences between BYD Han DM and DM-i: 1. Different advantages: DM-i has multiple advantages that lead other hybrid technologies. The core concept is to prioritize electricity and use fuel as a supplement. In terms of architecture, the DM-i super hybrid is based on a high-capacity battery and high-power motor, relying on the high-power motor for driving during vehicle movement. The main function of the gasoline engine is to charge the battery, and it only directly drives when more power is needed, working in synergy with the motor to reduce load. This hybrid technology differs from traditional hybrid technologies that rely heavily on the engine, thus more effectively reducing fuel consumption. 2. Different core technical components: The core components of BYD's DM-i super hybrid technology are the newly developed Xiaoyun plug-in hybrid-specific engines, which come in two versions: a 1.5L engine mainly used in Qin PLUS and Song PLUS, and a 1.5T turbocharged engine used in larger models like Tang DM-i. These models also feature two important components: the EHS dual motor and the DM-i super hybrid-specific Blade Battery, along with a series of vehicle control systems, engine control systems, motor control systems, and battery management systems, collectively forming the super hybrid system. Most importantly, these core components and key technologies are entirely independently developed by BYD. 3. Different driving forces: When the DM-i model has sufficient battery charge, it operates like a pure electric vehicle, with the motor providing enough power for driving under various road conditions. When the battery is low, the DM-i model autonomously decides whether to use electricity, fuel, or a combination of both based on system conditions. According to BYD's official data, in urban conditions, the vehicle is driven by the motor 99% of the time, offering a driving experience almost identical to a pure electric vehicle. Additionally, the engine is in a shutdown state 81% of the time during operation. During high-speed driving, both the engine and motor provide power to the wheels, with the engine always operating within the most efficient range.
