On August 12, the first batch of the L4-level cold chain unmanned vehicle, Xiaozhu A6 Pro, co-developed by MINIEYE (02431) and Yunnei Power, rolled off the production line at the Yunnei Power manufacturing base in Kunming. Yunnei Power Chairman Yang Bo and MINIEYE Vice President Guo Long attended the ceremony to mark this milestone. The two companies have integrated mature cold chain temperature control technology with map-free autonomous driving technology to create a new cold chain unmanned vehicle, reshaping industry standards for cold chain logistics. This official production launch signifies that the joint research, development, and integrated operational model between the two parties has entered a new phase of commercial deployment. The Xiaozhu A6 Pro is also the industry's first mass-produced map-free L4 cold chain unmanned vehicle.

Combining Strengths to Build Mass Production Capability for Unmanned Cold Chain
Cold chain logistics is a critical pillar for ensuring public supply and a key link connecting modern agriculture, commercial distribution, and the digital economy. In the unmanned delivery sector, specific scenarios like medical transport and fresh food delivery demand extremely high standards for compartment temperature control, delivery timeliness, and operational stability. Targeting these core industry needs, MINIEYE partnered with Yunnei Power to jointly define, develop, and mass-produce the Xiaozhu A6 Pro, specifically addressing existing pain points in transportation. As a benchmark company in China's commercial vehicle powertrain and complete vehicle sector, Yunnei Power brings deep expertise in vehicle R&D and a strong market presence, providing robust support for the high-quality batch delivery of the Xiaozhu A6 Pro. In this project, Yunnei Power leveraged its advantages in vehicle manufacturing, chassis platforms, system integration, and supply chain management. Meanwhile, MINIEYE contributed its leading L4-level map-free autonomous driving solution. The Xiaozhu A6 Pro is equipped with MINIEYE's self-developed iPilot 4 Max domain controller, utilizing a fully domestic hardware architecture and AI large model technology. It requires no pre-mapping of specific areas, allowing it to easily navigate complex road conditions such as rural roads, construction zones, and mixed traffic, significantly enhancing its generalization capability across diverse scenarios. Furthermore, leveraging map-free technology, the Xiaozhu A6 Pro can be deployed in as little as an hour, effectively reducing early-stage mapping and late-stage maintenance costs, perfectly aligning with the fast-expanding, time-sensitive delivery needs of the cold chain industry.
Professional Cold Chain Configuration with AI-Powered Intelligent Control
In terms of core cold chain capabilities, the Xiaozhu A6 Pro is equipped with a standard F-class refrigerated compartment. Using integrated hot and cold bidirectional temperature control technology, it achieves precise constant temperature regulation within a range of -20°C to +25°C, with a control accuracy of ≤±1°C. This meets the transport needs of various temperature zones, including fresh produce, frozen food, and medical reagents. The compartment is fitted with a full suite of cold chain intelligent equipment, including an ultraviolet sterilization device, dedicated LED lighting for refrigeration, and 24-hour video monitoring. Real-time data on temperature, humidity, sterilization records, and refrigeration unit status are synchronized to the cloud, enabling full traceability of the cold chain process.
Furthermore, the cold chain unmanned vehicle is equipped with an AI intelligent control system that connects the data links of the refrigeration unit, the vehicle's VCU (Vehicle Control Unit), and the remote dispatch platform. Utilizing adaptive intelligent algorithms, the Xiaozhu A6 Pro can autonomously adjust the temperature and dynamically optimize refrigeration energy consumption without any human intervention, supporting round-the-clock unmanned cold chain operations. The system also features a comprehensive intelligent warning mechanism. In the event of anomalies like temperature irregularities or equipment malfunctions, it can automatically issue alerts and make intelligent adjustments, ensuring the safety and reliability of the entire cold chain transport process.
It is reported that the first batch of Xiaozhu A6 Pro vehicles will be initially deployed in multiple locations across Yunnan, including Kunming, Chuxiong, Baoshan, and Lijiang. They can be widely adapted to diverse scenarios such as county and township cold chain distribution, urban fresh food transfer, and community food delivery. Looking ahead, MINIEYE and Yunnei Power will continue to deepen vehicle iterations, expand the deployment footprint to more cities, and accelerate the large-scale rollout of cold chain unmanned vehicles. Leveraging its map-free advantages and core cold chain technology, the Xiaozhu A6 Pro is set to become a new growth engine for MINIEYE in the smart cold chain sector, driving cost reduction and efficiency improvement in short-distance cold chain logistics through intelligent technology, and supporting the digital and green transformation of the cold chain industry.
