Shenzhen Busbar Sci-Tech Development Co. Ltd. (Ebusbar) was established in April 2010. As a national high-tech enterprise, it specializes in the research and development (R&D), manufacturing, and sales of core components for new energy vehicles (NEVs). As an integrated solution provider for high-voltage systems in NEVs, Ebusbar focuses on energy transmission, distribution, and management of high-voltage systems, continuously enhancing its product portfolio and manufacturing capabilities.

When asked why Ebusbar has set its sights on the NEV industry, its chairman Lin Guojun explained that the company’s goals align with China’s automotive industry development strategy and closely follow the industrial layout in Pingshan and Shenzhen.

Ebusbar initially operated in the fields of computers, communication, and consumer electronic products. Leveraging technological innovation, the company has developed a complete industrial chain and has been recognized as a “little giant” enterprise by the Ministry of Industry and Information Technology for utilizing specialized and sophisticated technologies to produce unique and innovative products.

Originally from Guizhou Province, Lin arrived in Shenzhen in 1991 at the age of 16. “Back then, I just hoped to find a factory job and settle down in Shenzhen,” Lin recalled. 

After being rejected by several factories, he moved to Pingshan and secured work at an electronics factory. Progressing from a cleaner to a production line worker and then to management, Lin founded his own company in 2000. With 2,000 yuan in savings and a 20,000 yuan loan from relatives, he purchased his first piece of equipment, which is now displayed at Ebusbar as a symbol of his early entrepreneurial challenges and aspirations.

Starting with OEM (Original Equipment Manufacturer) services, Lin steadily earned profits and eventually decided to enter the new energy sector. In 2010, Ebusbar was founded with the goal of developing its own high-voltage systems for NEVs.

The English name “Busbar” refers to laminated busbars. The company aims to use laminated busbars as a starting point to develop a complete high-voltage connection system solution for NEVs, with independently owned intellectual property rights.

During the 26th Summer Universiade in Shenzhen in 2011, the city deployed 3,810 vehicles to support transportation, with more than half being NEVs. “Shenzhen’s initiative gave me confidence that I was on the right path,” Lin said. Ebusbar later participated in several municipal and national NEV projects, further establishing its industry reputation.

In 2013, Pingshan District provided Ebusbar with subsidies for office rent and industrial space, prompting the company’s relocation to Pingshan. “This is where my ‘industrial dream’ began, and also where BYD’s global headquarters are located. It’s the perfect place for Ebusbar to grow and help Chinese NEVs go global,” Lin said.

Ebusbar has invested subsidies and support funds from district, city, provincial, and national levels into technological innovation, aiming to carve out new paths amid fierce NEV-industry competition. Its R&D efforts focus on new materials, conduction technologies, improved conduction efficiency and safety, and practical applications.

The company’s strong R&D capabilities and innovative power have earned it collaborations with leading firms, including BMW, with whom Ebusbar worked to develop the charging nozzle for BMW’s electric i3 model. “We learned a lot from German engineers through this collaboration,” Lin noted.

Ebusbar has also contributed to the formulation of national standards and holds over 600 patents. Lin emphasized that comprehensive support from Pingshan — from policy backing to innovation platforms and industrial chain cooperation — has boosted the company’s confidence in overcoming challenges.

Ebusbar primarily focuses on passenger vehicles, serving clients from second-tier to first-tier suppliers and covering components from batteries and motors to electronic control systems. The company plans to extend its product offerings to a wider range of NEV models and applications, and is aligning its future products with trends toward lightweight, high-power, standardized, and cost-effective solutions.

Ebusbar has been recognized by the Ministry of Industry and Information Technology for utilizing specialized and sophisticated technologies to produce unique and innovative products.

Beyond rent subsidies, Pingshan supports Ebusbar with incentives for expanding production capacity, improving efficiency, and providing financing loans designated for specialized, innovative “little giant” enterprises. As a leading hub for the NEV industry within the Guangdong-Hong Kong-Macao Greater Bay Area (GBA), Pingshan’s future prospects excite Ebusbar.

Lin revealed that Ebusbar’s products for NEVs have gained growing international recognition as China’s NEVs expand globally. He expects that soon, Ebusbar will enter the global market as an independent brand and become a flagship of Shenzhen’s NEV component industry. “We have chosen Pingshan as the base of Ebusbar’s global headquarters. From here, we will go global,” Lin affirmed.

“Our company is preparing to expand internationally. At the same time, we will leverage Pingshan’s advantages in advanced industries to position ourselves as a ‘lighthouse enterprise’ in intelligent car components,” Lin said. “I believe that as a hub for high-quality industrial development, Pingshan will emerge as the region with the most listed companies and headquarters, and the highest economic output in advanced industries,” he added.
