The global automotive industry is undergoing profound transformation, while the new energy vehicle sector has entered a new phase of upgrading, efficiency improvement and high-quality development. For more than 20 years, CHCD has maintained a close and reliable partnership with BYD. Starting from component supply projects, the two companies have stood side by side through years of challenges, building a solid alliance based on mutual trust, in-depth collaboration and strategic alignment. Upholding a commitment to manufacturing excellence and superior product quality, they have grown hand in hand and set a benchmark for strong cooperation and mutual empowerment across the automotive industrial chain.
A Cooperation Started with a Supplier Approval: The 20-Year Journey Begins
BYD stepped into complete vehicle manufacturing back in 2003. At that time, CHCD was already a leading manufacturer of wiper assemblies and cooling fan assemblies in China. Following thorough qualification reviews and strict supplier assessments, CHCD joined BYD’s supplier network, undertaking the simultaneous R&D and mass delivery of wiper assemblies and cooling fan assemblies for the BYD 318 model. This marked the official start of their long-term cooperation.
The partnership evolved from regular business collaboration to profound trust during a critical project in 2005. BYD’s F3, its iconic mainstream family car, was scheduled for launch in June that year. However, delays in the delivery and matching of outsourced components pushed back the launch timeline. What made it more challenging was that vehicle body parameters and operating conditions were continuously adjusted, meaning the design plans for wipers and cooling fans needed repeated revisions.
“Our engineers practically lived in the laboratory during that period,” recalled a senior engineer who took part in the project. “Every time we received updated parameters, we worked overnight to adjust structures and calibrate operating conditions, and sent samples for durability testing early the next morning.”
Leveraging mature synchronous development procedures and standardized quality control systems, CHCD completed structural adjustment, performance calibration and durability verification efficiently. All revised solutions, trial samples and deliveries were finished strictly on schedule. The final products passed all professional tests for vehicles and components at one go. The BYD F3 was officially launched on September 22, 2005, and soon became a blockbuster model in the domestic passenger car market.
The successful delivery of the F3 project laid a solid foundation for mutual trust in quality and on-time delivery. It also enabled CHCD to further integrate into BYD’s complete vehicle R&D and supporting system. With accumulated experience in rapid response, schedule management and vehicle matching, CHCD expanded its business scope from single-component supply to multi-category and platform-based supporting services, paving the way for over two decades of in-depth strategic cooperation.
Standing Together Through Difficult Times: Sincere Commitment Amid Market Fluctuations
It is easy to cooperate in prosperous times, yet true partnership is proven during hardships. From late 2008 to the first half of 2009, while the BYD F3 achieved strong market sales, the brand carried out in-depth optimization of its sales network. The overall automotive market turned cautious, and most component suppliers chose to hold back by cutting production and slowing down deliveries.
At this crucial moment, the management team of CHCD paid a visit to BYD’s headquarters. Both sides openly discussed the temporary operational difficulties and shared confidence in long-term development. Based on mutual understanding and shared vision, the two enterprises reached a tacit agreement without additional terms or special contracts.
Faced with extended payment cycles, CHCD stuck to the long-term partnership philosophy. The company made a firm commitment: no production cuts, no supply suspension, no price hikes and no reduction of supporting capacity. Production lines kept running at full capacity, and production and logistics teams worked around the clock to fully guarantee stable operation of BYD’s vehicle manufacturing bases. What started as a regular supply relationship turned into a sincere partnership forged through thick and thin.
Market volatility continued in 2010, and CHCD always stood firmly alongside BYD. Through multiple industry cycles, BYD grew steadily and took a leading position in the new energy vehicle industry. Meanwhile, thanks to its consistent reliability, outstanding product quality and strong sense of responsibility, CHCD developed from an ordinary component supplier into a core strategic partner deeply integrated within BYD’s key supply chain.
Non-Stop Supply Support: 300 Dedicated Trips for Zero Disruption & Zero Defects
Between 2020 and 2022, widespread pandemic restrictions brought unprecedented challenges to global supply chains. With traffic control across regions, logistics faced severe disruptions. BYD operated multiple production bases in Shenzhen, Xi’an, Changsha, Changzhou and Hefei, where assembly lines were at risk of shutdown due to material shortages.
CHCD immediately activated an emergency supply plan. The factory implemented closed-loop management, with employees staying on-site for continuous two-shift production. Priority was given to all component orders for BYD vehicles. Meanwhile, dedicated cross-regional logistics routes were launched to bypass restricted areas, with special delivery vehicles arranged for direct transportation.
“Our delivery vehicles often set off in the early hours. Drivers worked long shifts in full protective suits for over ten hours per trip,” said a logistics manager at CHCD. “No matter how urgent the delivery was, our quality engineers inspected every product thoroughly before shipment — quality could never be compromised.”
In three years, CHCD completed 300 dedicated cross-regional delivery trips, ensuring on-time shipments, consistent quality and uninterrupted supply for all BYD production bases. Throughout this period, there were zero supply disruptions and zero quality issues across all batches.
For its exceptional performance in supply guarantee and quality management, CHCD was awarded the Outstanding Quality Award by BYD and Fudi Technology in April 2021, setting an excellent example for supply chain collaboration under tough circumstances.
Expanded Full-Range Supporting Network: Leading Market Share with Solid Strength
As BYD expanded its product lineup into the Dynasty Series and Ocean Series, CHCD also realized a major upgrade from single-component supply to comprehensive systematic supporting services.
CHCD now provides a full range of products including front wipers, rear wipers, wiper linkages and drive motors, covering nearly all best-selling BYD models such as Qin, Song, Yuan, Tang, Han, Seal, Dolphin and Seagull. Its products fit perfectly with compact commuter cars, family vehicles, mid-to-high-end flagship models and performance coupes, achieving full coverage across BYD’s entire product portfolio.
Today, CHCD accounts for 55% of BYD’s external procurement volume for wiper systems, ranking first among all external wiper suppliers. The company maintains an annual supporting capacity of over 2 million sets. Thanks to sophisticated manufacturing techniques, closed-loop quality control and highly efficient production & delivery coordination, CHCD keeps its product yield and on-time delivery rate above industry averages, firmly securing its position as BYD’s core strategic supplier for wiper products.
Synchronized Technology Innovation: Five Generations of Product Upgrades to Embrace EV Trends
Driven by electrification and intelligent transformation, the automotive industry is evolving rapidly.
