What does BYD's DM-i mean?

[Harper]

BYD's DM-i is a super hybrid technology, whose core components include the Xiaoyun plug-in hybrid engine developed by BYD, the EHS dual-motor system, the DM-i super hybrid Blade Battery, and a series of vehicle control systems, engine control systems, motor control systems, and battery management systems, all of which together form a super hybrid system. When the DM-i has sufficient power, it operates like a pure electric vehicle, with the motor's power sufficient for driving under various road conditions. When power is insufficient, the DM-i model independently determines whether to use electricity, fuel, or a combination of both based on the system's operating conditions. This technology features one main motor and one auxiliary motor. The engine is only used for generating electricity for M1 and does not participate in driving the wheels. M2 is the main motor, which recovers energy during braking to charge the battery. DM-i primarily relies on a high-power, high-efficiency motor for driving. The main role of the gasoline engine is to generate electricity within its efficient speed range and, at appropriate times, directly drive the vehicle. By altering the traditional hybrid technology design that primarily relies on the engine, it significantly reduces fuel consumption.

BYD's DMI is their signature Dual Mode Intelligent hybrid system. I've driven their cars, and the experience is truly exhilarating. Simply put, it's a plug-in hybrid that can intelligently switch between pure electric and hybrid modes. The engine mainly generates electricity or provides minimal propulsion, ensuring no fuel is wasted. The electric motor takes the lead in driving, delivering astonishingly quick power response. In urban areas, you can typically drive 50 to 120 kilometers on pure electricity, enjoying quiet and cost-effective travel; on highways, it automatically switches to the engine, with fuel consumption dropping below 4L. Maintenance is also convenient, eliminating the range anxiety associated with pure electric vehicles. In the long run, the cost-saving benefits are significant, especially when charging during low electricity rates. Highly recommended for friends looking to save on fuel and be environmentally friendly.

I've been driving the BYD Han DM-i for a long time and know its DMI system well. DMI stands for Dual Mode Intelligent hybrid, meaning the car can run on either electricity or fuel. For my daily commute, I mostly use electric mode with zero fuel consumption, saving money. On long road trips, the system automatically switches to hybrid mode to ensure ample power. The intelligent management system is truly impressive, perfectly balancing energy without any waste. The average fuel consumption is 4.5L per 100km, with a range exceeding 1000km. The driving experience is smooth, quiet, and accelerates quickly. The battery has a long lifespan with a 10-year warranty, and the charging station supports fast charging, filling up most of the battery in just half an hour. This technology is worth trying—practical, efficient, and eco-friendly.

BYD DM-i is a highly efficient plug-in hybrid system. Its core components include a gasoline engine, a large battery pack, and a high-power electric motor. The engine primarily generates electricity, intelligently supporting the electric motor for propulsion. Pure electric driving saves fuel and operates quietly; in hybrid mode, fuel consumption drops to 4L per 100 kilometers. It offers smooth driving, long range, environmental friendliness, and cost savings.
