What is BYD's DM-i Technology?
1 Answers
The following is an introduction to BYD's DM-i technology: 1. Advantages of BYD DM-i: DM-i possesses multiple advantages that lead other hybrid technologies, with its "core philosophy" being electricity as the primary power source and fuel as supplementary. Architecturally, the DM-i Super Hybrid is based on a high-capacity battery and high-power electric motor. During driving, the vehicle relies on the high-power motor for propulsion, while the gasoline engine's main function is to charge the battery. It directly drives the wheels only when additional power is needed, and even then, it works in coordination with the motor to reduce load. This hybrid technology differs from traditional hybrid technologies that rely heavily on the engine, thereby achieving more effective fuel consumption reduction. 2. BYD DM-i's engine: The core component of BYD's DM-i Super Hybrid technology is the newly developed Xiaoyun plug-in hybrid dedicated engine, which comes in two versions: a 1.5L engine primarily used in Qin PLUS and Song PLUS, and a 1.5T turbocharged engine used in the larger Tang DM-i model. These models feature two key components: the EHS dual-motor system and the DM-i Super Hybrid dedicated 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.
