On December 14, Chezhi.com, China’s leading platform for collecting defective‑vehicle information and handling consumer complaints, jointly with Kairui Saichi Consulting, hosted an online ceremony for the release of Research Findings on Quality Performance of China’s New‑Energy Vehicle Three‑Electric Systems 2023 and the Award Presentation for Best‑Market‑Performance Three‑Electric‑System Suppliers. Industry associations, representatives of three‑electric‑system suppliers and 40 domestic media outlets were specially invited. The event interpreted market trends of new‑energy vehicles, unveiled the research outcomes on three‑electric‑system quality performance, and announced the winners of the Best‑Market‑Performance Three‑Electric‑System Supplier awards. 

For years, Kairui Saichi Consulting has kept improving its multi‑dimensional product research system centered on product quality while taking user attention and satisfaction into account. Since 2019, it has successively released the annual Automotive Quality Research (AQR) Report to empower enterprises to develop products driven by user demands. It set up an independent new‑energy vehicle segment in 2021 and focused its 2023 research on the quality performance of three‑electric systems.

Zhang Yue, Senior Vice President of Kairui Saichi Consulting, stated in his speech that Chinese new‑energy vehicle enterprises have become a vital force reshaping the global automotive industry. Chinese brands have delivered outstanding performance among three‑electric‑system suppliers, boasting remarkable advantages in technical capability, R&D strength, market share and cost scale. He expressed hopes that these outstanding suppliers would seize the overseas‑expansion opportunity and continuously deliver high‑quality Chinese solutions for three‑electric systems. 

Cui Dongshu, Secretary‑General of China Passenger Car Association (CPCA), pointed out that exports and new‑energy vehicles constituted key growth drivers for the automotive market in 2023. Automobiles are evolving from traditional mechanical tools into durable electronic consumer goods with greatly shortened service cycles and accelerated replacement. Future new‑energy vehicles will serve as high‑efficiency, low‑cost mobility tools, an independent third living space, as well as energy‑storage units for distributed energy systems.

Based on massive user complaint data and a multi‑dimensional quality‑performance research model, the released *Research on Quality Performance of China’s New‑Energy Vehicle Three‑Electric Systems (2023)* deeply explored users’ perceptions and attitudes toward three‑electric‑system quality issues and interpreted quality performance from the perspective of user experience. The research covered 24 vehicle brands, 19 powertrain suppliers and 22 battery‑system suppliers.

Key findings of the research are as follows:

Complaints concerning three‑electric systems of new‑energy vehicles kept rising overall. A total of 4,764 complaints were recorded from January to October 2023, exceeding the full‑year figure of 2022 and representing a 63% year‑on‑year increase.

Battery‑electric vehicles accounted for the largest share of three‑electric‑system complaints, while complaints for plug‑in hybrid electric vehicles surged by 125% year‑on‑year.

Failures tended to occur at an early stage of vehicle usage. 66.4% of three‑electric‑system malfunctions took place within one year after purchase, and failures were most frequent within a mileage range of 3,000‑10,000 kilometers.

Complaints for battery‑electric, plug‑in hybrid and extended‑range vehicles all mainly centered on power‑battery failures, inaccurate driving‑range readings and charging malfunctions.

According to the research, traction batteries are high‑value core components of new‑energy vehicles. Users are highly sensitive to battery quality, which easily triggers disputes with after‑sales service providers over fault resolution. Charging failures directly impair driving experience and have a low tolerance threshold among users.

This study also matched vehicle‑level quality performance with supplier brands, and analyzed the quality performance of powertrain and battery‑system suppliers across two market segments: economy‑grade and mid‑to‑high‑end. The final results are shown below:

No.1 in quality performance among powertrain suppliers for economy‑grade new‑energy passenger vehicles: Founder Motor;

No.1 in quality performance among powertrain suppliers for mid‑to‑high‑end new‑energy passenger vehicles: Huawei Digital Power;

No.1 in quality performance among battery‑system suppliers for new‑energy passenger vehicles: FinDreams Battery.
