Mass Production Exceeds 500,000 Units! Jingwei Hirain XCU's Path to Integrated Breakthrough
Release time:
2025-12-16 10:26
With Jingwei Hirain's XCU reaching its 500,000th unit in mass production, its integrated solution has been fully deployed in the Geely Galaxy, helping this model maintain its position as the top-selling vehicle across all categories.
Amid the rapid advancement of new energy vehicles, the integration of electric drive systems and the domain-based architecture of electronic/electrical systems have emerged as two distinct trends. Against this backdrop, Jingwei Hirain's XCU (X-in-One Control Unit) solution represents more than mere “bundling” or “unified installation.” It signifies a pivotal step in the evolution of vehicle electronic/electrical architecture—shifting from decentralization to centralization, and advancing from hardware integration toward deep integration of control logic. As the industry's demand for higher-level control integration grows increasingly urgent, the emergence of functional domain controllers like XCU not only responds to technological trends but also lays a solid architectural foundation for the future of “software-defined vehicles.”
▎Three Major Pain Points of Traditional Architectures
Under traditional distributed electronic architectures, an intelligent electric vehicle typically houses over 100 electronic control units (ECUs). These ECUs are developed independently and deployed in a dispersed manner, not only increasing system complexity but also presenting three increasingly prominent challenges:
- High Wiring Complexity: In traditional architectures, a vehicle's wiring harness extends up to 5 kilometers in length, accounting for nearly 5% of the vehicle's total weight. This makes it one of the heaviest components in the low-voltage electrical system. It not only consumes space but also increases costs and assembly complexity.
- Significant cost pressure: Each function requires a dedicated controller, leading to redundant investments in chips, housings, and development. This lack of cross-model reusability drives up overall vehicle R&D and manufacturing costs.
- Complex cooling systems: Dispersed heat-generating components necessitate separate cooling circuits for each module, along with distinct pumps or valves for control. This results in numerous pipes and intricate control logic, further increasing costs and energy consumption.
▎Jingwei Hirain XCU: Industry Solution with Centralized Integrated Architecture
Addressing industry pain points, Jingwei Hirain leverages years of automotive electronics expertise to introduce the XCU - a highly integrated main control unit. This solution systematically resolves challenges inherent in traditional architectures and has been deployed in Geely Galaxy models. With cumulative shipments exceeding 500,000 units and a reputation for consistent quality, the XCU demonstrates proven maturity and high reliability.
• Architectural Innovation: From “Functional Silos” to “Centralized Brain”
The XCU integrates multiple traditional standalone units—including the vehicle controller, thermal management controller, gateway, and motor controller—onto a single hardware platform. It also provides bootstrap circuits for components like the on-board charger (OBC) and DC/DC converter. Future iterations may further integrate core algorithms from the battery management system, reducing computational load on the microcontroller within the battery pack. Compared to traditional CAN bus communication, XCU employs high-speed on-chip communication for faster response, higher reliability, and significantly simplified wiring harness layout and vehicle assembly processes.
• Balancing Cost Efficiency and Safety
The XCU replaces multiple standalone controllers with a single Infineon AURIX™ TC3x series main controller chip. This significantly reduces the number of chips and controller housings, lowering hardware costs and failure rates while enabling simpler, more efficient thermal management. While optimizing costs, safety remains uncompromised—its main controller chip supports the highest ASIL D functional safety rating. Critical systems like the accelerator pedal and motor control feature hardware redundancy design, with real-time monitoring and tiered alerts for core parameters, ensuring driving safety remains under control.
The successful implementation of XCU represents not only a breakthrough for a single product but also a significant step in the evolution of automotive electronic architecture toward domain control. As it expands across more vehicle platforms, Jingwei Hirain is committed to establishing XCU as the industry benchmark for integrated power-domain control units.
Moving forward, Jingwei Hirain will continue deepening its technological expertise to drive iterative upgrades of the XCU and expand its application across multiple vehicle models. Through high-quality, cost-effective technical solutions, the company aims to propel China's intelligent electric vehicles toward higher levels of development, delivering more reliable, efficient, and intelligent mobility experiences for global users.
