Since the implementation of China's first electric vehicle (EV) annual inspection standard, the Regulations for Safety Performance Inspection of Electric Vehicles in Operation, the safety management of EVs has entered a new phase characterized by "standardization and traceability." Seizing this pivotal moment of industry transformation, J-Blue Technology, a subsidiary of Duolun Technology, has collaborated with Zhongjian Chefu Testing Technology (Beijing) Co., Ltd., a subsidiary of China Automotive Engineering Research Institute (CAERI), to jointly build and officially operate a digital-intelligent EV inspection station in Beijing.

Located in the Beijing Economic-Technological Development Area, this inspection station leverages cutting-edge technological capabilities to strictly adhere to national standards, establishing itself as a benchmark EV inspection facility in North China and laying a solid foundation for the safe development of the industry.

Central SOE Leadership with Technology Empowerment: A Deep Integration of Authority and Expertise

As a national-level central state-owned enterprise, CAERI has long been deeply engaged in the automotive inspection sector, possessing top-tier industry qualifications, profound technical expertise, and high credibility. It serves as a core driver in the implementation of vehicle inspection standards and the standardized development of the industry. Its subsidiary, Zhongjian Chefu Testing Technology (Beijing) Co., Ltd., as the operator of this central SOE flagship annual inspection station, continues to provide professional and reliable inspection services to the industry.

J-Blue Technology, a Duolun Technology subsidiary specializing in automotive inspection, has independently developed comprehensive inspection solutions for both conventional vehicles and EVs. With operations spanning more than 20 provinces and services to over 500 inspection stations nationwide, it has built a solid market foundation.

By deeply integrating the strengths of both parties, they have jointly established a high-standard, fully compliant EV inspection platform, truly fulfilling the mission of "serving national strategy, advancing industry development, and safeguarding public safety."

Self-Developed Equipment with Full Compliance: Fully Meeting the New EV Annual Inspection Standards

J-Blue Technology has provided this inspection station with a complete digital-intelligent EV inspection line, featuring the following core equipment:

• EV Charging Safety Inspection Equipment

• EV Discharging Safety Inspection Equipment

• On-Board Diagnostic (OBD) Terminal Testing Equipment

• Digital-Intelligent Supporting Software Systems

This equipment fully covers the four major inspection categories mandated by the Regulations for Safety Performance Inspection of Electric Vehicles in Operation:

• Power Battery Safety

• Drive Motor Safety

• Electronic Control System Safety

• Electrical Safety

Notably, the three core EV inspection devices developed by J-Blue Technology through national research initiatives – including the EV charging safety inspection equipment, discharging safety inspection equipment, and diagnostic terminal testing equipment – are now fully operational at Zhongjian Chefu Testing Technology (Beijing) Co., Ltd. These devices feature industry-leading wheelbase adaptability covering the vast majority of EV models on the market, incorporate multiple safety protection mechanisms, and have all passed certification by the Ministry of Public Security.

Comprehensive Scenario Coverage with Closed-Loop Data: Full-Service Inspection Capabilities Ensuring Controllable Safety Risks

Leveraging these self-developed equipment and the endorsement of a central SOE platform, this inspection station is equipped to provide professional services across multiple scenarios:

• EV Annual Inspection Services: Strictly executed in accordance with national standards, ensuring traceable data and trustworthy results.

• Pre-Sale Vehicle Quality Inspection: Providing safety assessments for automakers and dealers prior to new vehicle delivery.

• In-Service Vehicle Safety Evaluation: Offering health checks for core components such as power batteries and electronic control systems for existing EV owners.

This means the inspection station can handle the full chain of inspection services, from new vehicle delivery through daily usage to annual mandatory inspections, truly achieving "traceable inspection data and controllable safety risks."

Furthermore, as a central SOE flagship station, the inspection process is transparent and standardized. Vehicle owners can clearly understand the safety status of their vehicles, and regulatory authorities can obtain standardized inspection data to support industry policy optimization.

Continued Deepening Commitment with Lifecycle Safeguarding: Technology-Driven Advancement for High-Quality EV Industry Development

Duolun Technology's J-Blue Technology will seize the opportunity presented by the implementation of the new national standards, continuing to increase investment in EV inspection technology R&D, iteratively upgrading core equipment performance, and continuously expanding the depth and breadth of its inspection services. Duolun Technology will also continue to collaborate with ecosystem partners such as CAERI to promote the tangible implementation of professional EV inspection services, contributing to the safer, more standardized, and higher-quality development of China's EV industry.
