Across the mountains and plains of Guangxi, an expressway network stretching over 10,000 kilometers forms a critical artery for regional economic development and public mobility. Behind the smooth operation of this vast transportation system lies a complex electromechanical and digital infrastructure, where power reliability is essential to safety, efficiency and continuity.

The successful completion of the Guangxi Expressway UPS and Battery Upgrade Project has significantly strengthened this digital backbone. As a key equipment supplier, KSTAR delivered a comprehensive electrical solution, ensuring stable and secure operation of the expressway’s electromechanical systems and earning strong recognition from the client.

Project Background

Partnering with the Core Force of Smart Transportation

The project was led by Guangxi Computing Center Co., Ltd., the core digital and smart transportation arm of Guangxi Transportation Investment Group. Established in 1978, the organization is recognized as a national-level innovation demonstration enterprise and a Specialized, Sophisticated, Distinctive, and Innovative enterprise, with multiple provincial research platforms and top level certifications such as CMMI Level 5.

As a key driver of expressway digitalization, Guangxi Computing Center plays a vital role in supporting Guangxi’s transportation information infrastructure, making this UPS and battery upgrade a critical project.

Project Strict Requirements

Complex Environments and Stringent Power Requirements

Covering expressway sections across the entire Guangxi region, the project faced multiple strict requirements:

• Highly diverse installation environments, from remote outdoor equipment rooms to central control hubs

• Strict requirements for power stability, safety, and reliability

• Continuous operation demands for critical systems such as tolling, communications, monitoring, and tunnel emergency lighting

After extensive technical evaluation, Guangxi Computing Center selected KSTAR based on its independent R&D capability, proven product reliability, and full lifecycle service assurance.

KSTAR Solution

A Fully Integrated and Secure Electrical System

To meet the project’s diverse requirements, KSTAR delivered a customized, end-to-end power solution, including:

• 35 UPS Systems

• 11 EPS Systems

• 2,427 Battery Units

• 65 Battery Cabinets, Supporting Accessories

KSTAR’s UPS systems, featuring double-conversion online architecture with isolation transformers, were deployed as the core power protection units, providing strong overload capability and stable performance in complex environments.

For tunnel emergency lighting applications, KSTAR’s KS-D series ensure millisecond-level switching to emergency power, maintaining uninterrupted illumination for LED emergency lights and significantly enhancing tunnel driving safety.

Project Value

Setting a New Benchmark for Expressway Power Systems

The successful delivery of the Guangxi Expressway project represents another benchmark case for KSTAR in the expressway sector. KSTAR’s multi-scenario power solutions for highways have already been widely applied in expressway projects across Yunnan, Guangdong, Jiangsu, Henan, and Shandong, supporting the stable operation of intelligent transportation systems nationwide.

Beyond traditional power protection, KSTAR’s solutions also extend to service area charging infrastructure, where its full liquid cooled ultra-fast charging solutions have been deployed in multiple provinces. Together with the Guangxi project, these applications demonstrate KSTAR’s strong capabilities across both conventional electromechanical power systems and emerging new energy scenarios.

Looking Ahead

Empowering the Digital Transformation of Transportation

From core power equipment to full-scenario energy solutions, KSTAR remains committed to independent innovation, safety, and reliability across key sectors including transportation, data centers, and new energy. With a complete portfolio covering UPS, EPS, and battery systems, combined with integrated capabilities spanning data centers and solar-storage-charging solutions, KSTAR continues to provide stable energy foundations for digital infrastructure while supporting greener and more efficient energy utilization.

Looking forward, KSTAR will continue to respond to the evolving needs of smart transportation with forward-looking technologies and solutions, helping build a more secure, intelligent, and sustainable future for digital transportation infrastructure.
