What is the principle of BYD DMI?

The dual-motor series-parallel hybrid structure eliminates the traditional gearbox of fuel vehicles.

DM-i super hybrid technology is based on the design of high-security blade batteries and high-performance high-power motors. It mainly relies on high-power and efficient motors for driving. The main responsibility of the gasoline engine is to rotate at high-efficiency speeds. Interval power generation.

And directly drive the vehicle at the right time, by changing the engine-based design of traditional hybrid technology, thereby significantly reducing fuel consumption.

Extended information

The core components of DM-i super hybrid include the dual-motor EHS super electric hybrid system, Xiaoyun-plug-in hybrid dedicated high-efficiency engine, DM-i super hybrid Special power blade battery and vehicle control system, engine control system, motor control system, and battery management system. These core components and key technologies are completely independently developed by BYD.

Compared with fuel engines, motor drives are more efficient and environmentally friendly. The DM-i super hybrid's electric-based architecture truly achieves more electricity use, less oil use, and efficient oil use. When the battery is sufficient, the DM-i super hybrid is a pure electric vehicle.

When the battery is low, the DM-i super hybrid is an ultra-low fuel consumption hybrid: when driving in urban areas, it is driven by the motor 99% of the time, and the driving experience is infinitely close. For pure electric vehicles, 81% of the operating conditions are when the engine is in a stalled state, with completely zero fuel consumption;

High-speed driving is mainly based on parallel direct drive, and the engine is driven in a high-efficiency range, which simplifies the energy transfer link and achieves ultra-fast driving. High efficiency and ultra-low fuel consumption.
