On June 13th, Great Wall Motors (GWM) officially unveiled its Intelligent Power Domain and Super Hybrid System (Hi4-G) for commercial vehicles at a media briefing. This marks a significant step in GWM’s strategy to provide innovative power solutions tailored for the new energy era in commercial transportation.
Full-Stack In-House Development: The Intelligent Power Domain
With the rollout of the first PT model of Great Wall’s commercial vehicles, the company has accelerated its market entry. As commercial vehicles transition from conventional fuels to new energy sources, the integration of intelligent connectivity with vehicle systems has become increasingly crucial. Leveraging the ecosystem of Great Wall Motors, the company has developed a pioneering intelligent power domain solution for commercial vehicles, addressing key pain points in logistics operations.
The Great Wall Intelligent Power Domain is designed as a comprehensive power system solution for vehicles and specific operational scenarios. It features in-house developed hardware such as power batteries, dual-motor central drive systems, super hybrid gearboxes, and dual-motor integrated axles. These components are paired with an intelligent brain with exceptional computational capabilities, aiming to enhance the operational intelligence of commercial vehicles and the efficiency of logistics.
At the heart of this solution is Great Wall’s first self-developed 9-in-1 power domain controller. This controller integrates nine critical control functions, including vehicle control, transmission control, motor control, battery management system, and steering control. By consolidating these functions, the system reduces the number of chips by 40% and shortens the vehicle’s wiring harness by 20%. This integration leads to lower energy consumption and higher power output through a unified hardware and software design.
One notable feature of the Intelligent Power Domain is its FOTA (Firmware Over-the-Air) capability, allowing seamless updates tailored to specific vehicle applications and scenarios. This makes the vehicle more adaptable to various operational conditions and supports pure electric, hybrid, and hydrogen platforms.
User-Centric Super Hybrid System: Hi4-G
Focusing on user needs is a core principle of Great Wall Motors. In the current logistics market, high fuel prices and low freight rates have made optimizing Total Cost of Ownership (TCO) essential for logistics operators. Fuel costs account for one-third of TCO, making fuel efficiency a critical factor in cost reduction.
The newly launched Hi4-G hybrid system is a testament to Great Wall’s technological prowess. Hi4-G stands for Hybrid Intelligent Four-wheel drive with a focus on high efficiency and profitability. This system is a breakthrough in scenario-driven vehicle design, specifically aimed at reducing TCO for commercial vehicle users.
World’s First 8-Speed DHT Transmission for Commercial Vehicles
The Hi4-G system incorporates the world’s first 8-speed Dual-Hybrid Transmission (DHT) designed for commercial vehicles. This system, built on the award-winning Great Wall DHT hybrid technology, features a unique “Three Engines, Eight Gears, Ten Modes” configuration, significantly lowering TCO.
Technologically, the Hi4-G system combines a high-efficiency internal combustion engine, a high-rate power battery, and the 8-speed DHT transmission to switch between over ten operating modes. These modes include serial, parallel, and mixed hybrid configurations, managed by intelligent control algorithms. This setup enables the powertrain to deliver optimal performance across various scenarios such as city driving, highway cruising, safe braking, and parking, ensuring maximum energy efficiency and power output.
The Intelligent Power Domain is the cornerstone of Great Wall’s strategy to provide highly intelligent, reliable, and low-TCO green solutions for the logistics industry. The Hi4-G system builds on Great Wall Motors’ extensive expertise in electric and hybrid technologies, offering a cost-effective, efficient platform tailored to commercial vehicle usage scenarios.
Looking forward, Great Wall Motors is committed to continuous innovation, substantial investment in research and development, and promoting the green, intelligent upgrade of the logistics industry. This launch is a significant milestone in GWM’s ongoing journey to enhance commercial vehicle performance and operational efficiency while reducing environmental impact.
