BYD Super DM Hybrid Technology

BYD Super DM (Dual Mode) Technology is a pioneering advancement in intelligent plug-in hybrid (PHEV) engineering. Exclusively developed by BYD, it offers a range of benefits, including greater energy efficiency, reduced fuel consumption, improved driving performance, and enhanced comfort.

How is BYD Super DM different?

BYD Super DM Technology distinguishes itself from other PHEV systems with an electric-focused hybrid design. It relies primarily on a high-power motor and a large-capacity battery, with the engine providing supplementary support. This innovative setup prioritises efficiency and adapts effortlessly to a wide range of driving conditions.

What are the benefits?

When fully charged, the vehicle operates as a purely electric car. As the battery depletes, it shifts to an ultra-low fuel consumption hybrid mode, still prioritising electric power while using minimal fuel. This eco-friendly system maximises energy efficiency, reduces fuel consumption, and delivers a quiet, comfortable ride without sacrificing 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) incorporates a highly integrated powertrain, combining high-speed dual motors, dual controllers, and advanced oil-cooling technology to boost motor power density and overall efficiency.

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

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

Hairpin Motor Technology
Utilising advanced hairpin technology, the EHS greatly improves heat dissipation, achieving peak efficiency of up to 97% and maintaining stability above 90% in most operating scenarios.

Oil Cooling Technology
The system employs targeted oil cooling to dissipate heat effectively, boosting motor power density to a maximum of 5.5 kW/kg.

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

Xiaoyun 1.5L/1.5T Hybrid engine

The Xiaoyun engine, purpose-built for Super DM Technology, pairs world-class thermal efficiency with a compact, streamlined design, delivering exceptional peak power and torque for outstanding performance.

A large capacity Blade Battery

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

Enhanced Safety
The Blade Battery successfully passes the rigorous Nail Penetration Test without igniting or producing smoke.

Optimised Strength
Each cell acts 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, improves vertical rigidity.

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

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