BYD Super DM Hybrid Technology

BYD Super DM (Dual Mode) Technology represents a groundbreaking advancement in intelligent plug-in hybrid (PHEV) engineering. Developed exclusively by BYD, it delivers numerous benefits, including improved energy efficiency, lower fuel consumption, enhanced driving performance, and increased comfort.

How is BYD Super DM different?

BYD Super DM Technology sets itself apart from other PHEV systems with an electric-focused hybrid architecture. It relies mainly on a high-power motor and a large-capacity battery, with the engine providing supplementary support. This innovative design prioritises efficiency and adapts seamlessly to a variety of driving conditions.

What are the benefits?

When fully charged, the vehicle runs as a pure electric car. As the battery level drops, it switches to an ultra-low fuel consumption hybrid mode, prioritising electric power while using minimal fuel. This eco-friendly approach maximises energy efficiency, lowers fuel consumption, and provides a quiet, comfortable ride without compromising on power or responsiveness.

The three core components of Super DM Technology

BYD Super DM technology is made up of 3 core components:

Electric Hybrid System (EHS)

The Electric Hybrid System (EHS) features a highly integrated powertrain, combining high-speed dual motors, dual controllers, and advanced oil-cooling technology to enhance motor power density and overall efficiency.

Peak Power: 145 kW / 150 kW
Peak Torque: 300 Nm

High-Speed Dual Motors
The EHS employs powerful high-speed dual motors with a maximum speed of 15,000 rpm. The P1 motor generates power, while the P3 motor drives the wheels, delivering outstanding performance across a wide range of driving conditions.

Hairpin Motor Technology
By using innovative hairpin technology, the EHS significantly improves heat dissipation, achieving peak efficiency of up to 97% and maintaining stability above 90% under most operating conditions.

Oil Cooling Technology
The system incorporates oil cooling that targets the heat source directly, enhancing heat dissipation and increasing motor power density to a maximum of 5.5 kW/kg.

Highly Integrated Dual-Motor Controller
The IGBT-based dual-motor controller elevates overall electronic control efficiency to an impressive 98.9%, ensuring precise and responsive power delivery.

Xiaoyun 1.5L/1.5T Hybrid engine

The Xiaoyun engine, specifically engineered for Super DM Technology, combines world-class thermal efficiency with a compact, streamlined design, delivering impressive peak power and torque for superior performance.

A large capacity Blade Battery

BYD Super DM Technology incorporates a customised version of the acclaimed Blade Battery, engineered specifically for the hybrid platform. With capacities starting at 18.3 kWh, it offers a pure electric range of up to 43 miles. Key benefits include:

Enhanced Safety
The Blade Battery passes the stringent Nail Penetration Test without igniting or emitting smoke.

Optimised Strength
Each cell functions as a structural beam within a single pack, resisting external forces. An aluminium honeycomb-like structure, reinforced with high-strength panels on the top and bottom, enhances vertical rigidity.

Extended Range
Compared with conventional battery packs, the Blade Battery improves space utilisation by 50%, boosting energy density and delivering a longer driving range.

Longer Lifespan
Designed for durability, the Blade Battery exceeds 5,000 charge and discharge cycles, ensuring long-lasting, reliable performance.
