What is the Principle of DM-i Super Hybrid?
2 Answers
dm-i super hybrid principle is an electric hybrid architecture centered around high-power drive motors and high-capacity power batteries as the main energy source, with the engine as a supplement. Features of DM-i: The DM-i super hybrid primarily relies on high-power, high-efficiency motors for driving. The main function of the gasoline engine is to generate electricity within the efficient RPM range and provide direct drive when necessary. This approach changes the traditional hybrid technology design that mainly depends on the engine and is oil-centric, thereby significantly reducing fuel consumption. DM-i applicable models: The core components of BYD's DM-i super hybrid technology are the newly developed Xiaoyun plug-in hybrid-specific engines by BYD, which come in two different versions—the 1.5L engine is mainly used in Qin PLUS and Song PLUS, while the 1.5T turbocharged engine is used in larger models like the Tang DM-i.
I've been driving my DM-i car for almost two years now, and the system's principle is quite straightforward. It primarily uses a high-power electric motor to drive the wheels, while the gasoline engine mostly doesn't drive directly but acts as a generator to charge the battery. During city commuting, the pure electric mode is quiet, cost-effective, and provides quick acceleration; on highways or when climbing hills, the engine starts to generate electricity, ensuring high efficiency and energy savings with a fuel consumption of just 3-4L/100km. When the battery is low, the engine charges while driving, so you never run out of power and get stranded. I charge at home for about two hours weekly, and a full charge gives me around 110 kilometers of pure electric range. Maintenance is simple with no spark plug issues, and the driving is smooth like an electric car with no jerking. The overall design intelligently balances power and fuel, cutting my monthly fuel costs in half while being eco-friendly, making it super cost-effective for family use.
