What is the working principle of BYD DM-i?
1 Answers
BYD's hybrid DM-i working principle is based on the design foundation of high-safety blade batteries and high-performance high-power motors, primarily relying on high-power efficient motors for driving. The main role of the gasoline engine is to generate electricity within the efficient RPM range and directly drive the vehicle at appropriate times. By altering the traditional hybrid technology's engine-centric design, it significantly reduces fuel consumption. The relevant introduction of DM-i is as follows: Introduction to DM-i: DM-i has multiple advantages that lead other hybrid technologies, and its "core concept" is to prioritize electricity with fuel as a supplement. In terms of architecture, the DM-i super hybrid is based on large-capacity batteries and high-power motors. During driving, the vehicle relies on high-power motors for propulsion, while the gasoline engine's primary function is to charge the battery, only directly driving when more power is needed and working in tandem with the motor to reduce load. This hybrid technology differs from traditional hybrid technologies that depend on the engine, thereby more effectively lowering fuel consumption. Applicable Models: The core components of BYD's DM-i super hybrid technology are BYD's newly developed Xiaoyun plug-in hybrid-specific engines, which come in two different versions—the 1.5L engine is mainly used in the Qin PLUS and Song PLUS, while the 1.5T turbocharged engine is used in the larger Tang DM-i model.
