As an authoritative award in the field of China's automotive supply chain, the "Golden Collection Award" has always been committed to "discovering good companies, promoting good technology, and achieving automotive professionals". As a company that has been deeply involved in the automotive industry for many years, Pinjia actively promotes the intelligent and electrified transformation of China's automotive industry with strong technical support and supply chain integration capabilities. By continuously deepening and expanding its technological innovation capabilities, the company has built a comprehensive service ecosystem from upstream original factory agents to downstream technical support, which can help customers quickly complete design verification and system integration, accelerating their development process from conceptual design to functional verification.

12V&48V intelligent power distribution system solution, breaking through the bottleneck of traditional power distribution

With the rapid development of electric vehicles and intelligent assisted driving technology, the continuous evolution of automotive electronic and electrical architecture, multi module collaborative operation, and the continuous improvement of functional safety standards have become important issues facing the industry. The 12V&48V intelligent power distribution system that won this award is an innovative solution launched by Pinjia in collaboration with Infineon's technical team. This solution adopts an intelligent distribution architecture that deeply integrates software and hardware, and is compatible with both 12V and 48V dual voltage platforms. During design, high-power loads such as chassis, amplifiers, and thermal management can be distributed in a 48V system, while low-power loads such as radar, lighting, wipers, doors, and windows can be distributed in a 12V system. The plan also reserves 12V/48V load channels to meet various expansion needs.

Not only that, the solution supports multi-channel communication and flexible configuration, with programmable protection logic that can achieve real-time diagnosis, warning protection, and recoverable control, fully in line with the trend of future automotive electronic and electrical regionalization and safety level improvement. At present, the plan has been approved by the car factory and prototype testing has been completed.

At the technical implementation level, this solution introduces a recoverable eFuse design. After triggering the protection mechanism, the system can reset without replacing any components, significantly reducing the customer's subsequent maintenance costs and operational burden. Compared with traditional fuses that only provide single overcurrent protection, this design has comprehensive diagnostic and protection capabilities, which can monitor and quickly respond to various fault situations such as overvoltage, undervoltage, overcurrent, and overtemperature in real time, providing more refined and predictable protection for the safety of vehicle power distribution. In addition, in terms of safety design, this solution strictly follows the functional safety process from the initial stage, and can support safety requirements up to ASIL D level, which can meet the strict standards for safety and reliability of core components in the era of intelligent driving.

Deepen the comprehensive layout of automotive electronics, and empower the smart travel "core" ecology with innovative technology at the Dalian University

Da Da Da Da Pin Jia Group has always regarded automotive electronics as its core strategic direction, continuously increasing investment in automotive technology research and development and ecological construction. In the face of the "new four modernizations" wave in the automotive industry, the company relies on its strong resource integration capabilities as the cornerstone. It not only focuses on the supply of key components for electrification and intelligence, but also deeply lays out in high growth tracks such as intelligent cockpit, vehicle networking, and energy management. By closely collaborating with domestic and foreign original factory partners, Pinjia further empowers vehicle manufacturers and Tier 1 manufacturers to accelerate product iteration and system integration, thereby helping them occupy key nodes in the rapidly evolving automotive electronics value chain.

In terms of product supply, Dalian University relies on a global supply chain network and digital management capabilities to ensure stable supply and rapid response of automotive grade key components. In addition to hardware support, Dalian University also collaborates with software suppliers to provide more complete software and hardware solutions, supporting customers in all aspects of design and production.

Facing the new stage of "software defined, data-driven" in the automotive industry, as a company that has been deeply rooted in the industry for 20 years, Dalian University will no longer be limited to the traditional role of "distributor", but will take technological innovation as the cornerstone, resource ecology as the support, transform cutting-edge technologies into competitive advantages that customers can quickly deploy, and use a resilient and agile supply chain system to safeguard the innovation journey of the automotive industry.
