Overview of BYD Hybrid Technology

BYD's hybrid technology, branded as Super DM (Dual Mode) Plug-in Hybrid Technology, represents a significant advancement in the automotive industry's push towards sustainability and efficiency. By integrating both electric and internal combustion engine (ICE) powertrains, BYD hybrids offer drivers the flexibility to operate in multiple modes, catering to varying driving needs and conditions. This dual-mode system not only enhances fuel efficiency but also reduces emissions, contributing to a greener environment.

Core Architecture

The foundation of BYD's hybrid system lies in its sophisticated architecture, which combines high-power electric motor drives with a large-capacity proprietary Blade Battery. This integration ensures that the vehicle can operate efficiently in both electric-only and hybrid modes.

• Electric Motor Drive: BYD employs dual electric motors that provide high torque and instant response, essential for both urban driving and performance applications.
• Blade Battery: The Blade Battery is a lithium iron phosphate (LFP) battery known for its safety, durability, and high energy density. With capacities starting from 18.3 kWh, it enables extended electric-only driving ranges, reducing the need for frequent refueling.
• Internal Combustion Engine: Serving as an auxiliary power source, the ICE complements the electric motors by providing additional power when required, such as during high-speed cruising or when the battery charge is low.

Dual-Mode Operation

The dual-mode operation is the cornerstone of BYD's hybrid technology, allowing the vehicle to switch seamlessly between different driving modes based on real-time driving conditions and driver preferences.

Electric Mode (EV Mode)

In electric mode, the vehicle operates solely on electric power derived from the Blade Battery. This mode is ideal for short-distance commuting and urban driving, providing a quiet, emission-free, and cost-effective driving experience.

Hybrid Mode

When additional power is needed or the battery charge is low, the internal combustion engine activates to assist the electric motors. This hybrid mode ensures that the vehicle maintains optimal performance and fuel efficiency, especially during longer trips or high-speed driving.

Series Mode

In series mode, the ICE functions as a generator to produce electricity, which is then used to charge the battery or power the electric motors. This mode is particularly effective during stop-and-go traffic, where maintaining a steady electric drive can significantly enhance fuel economy.

Parallel Mode

Parallel mode engages both the ICE and electric motors simultaneously to provide maximum power output. This mode is suitable for dynamic driving conditions, such as overtaking or climbing steep gradients, ensuring that the vehicle delivers the necessary torque and acceleration.
