Automobile dmi is the system of plug-in hybrid electric vehicle. Its core components are Xiaoyun plug-in hybrid engine, ehs dual motors, dmi super hybrid blade battery developed by BYD, and a series of vehicle control systems, engine control systems, motor control systems and battery management systems. * * * together constitute a super hybrid system. Dmi super hybrid power is based on high-capacity battery and high-power motor. When the vehicle is running, it is driven by a high-power motor. The main function of gasoline engine is to charge the battery, and direct drive needs more power. Only by working with the motor can the load be reduced. This hybrid technology is different from the traditional hybrid technology, which depends on the characteristics of the engine, thus reducing fuel consumption more effectively. When fully charged, the dmi model is equivalent to a pure electric vehicle, and the power supply of the motor is enough to drive in various road conditions. When the power is insufficient, dmi models will independently judge whether to use electricity or oil, or a combination of oil and electricity according to the working conditions of the system.
