BYD Faces Twin Headwinds: Battery Share Slips to 17% as Intelligent Driving Conference Tests Strategy
26.05.2026 - 13:32:25 | boerse-global.de
China’s electric-vehicle powerhouse is navigating a delicate balancing act. Just as BYD prepares to showcase its artificial intelligence and driver-assistance ambitions at a high-profile technology event, new data reveals that its in-house battery unit is losing ground to archrival CATL at an accelerating pace. The juxtaposition underscores how the company’s vertic integration model — long seen as a competitive moat — is becoming a source of vulnerability.
The domestic battery market expanded roughly 15% in April to 62.4 gigawatt-hours, yet BYD’s subsidiary FinDreams captured only 17% of that volume, according to the China Automotive Battery Innovation Alliance (CABIA). CATL, by contrast, held a commanding 47% share. Over the first four months of the year, FinDreams has ceded more than seven percentage points of market share compared with the same period in 2025.
The root cause is plain: FinDreams sells the vast majority of its batteries to its parent company. Though emerging automakers such as Xiaomi and Xpeng also source from BYD, their volumes remain marginal. That dependency turns every wobble in BYD’s own vehicle sales into a direct drag on the battery unit. In April, BYD delivered 321,123 new-energy vehicles, down sharply from 380,089 a year earlier. The cumulative tally for the first four months stands at roughly 1.02 million units, versus nearly 1.38 million in the year-ago period.
Those delivery figures reinforce a broader financial deterioration. For the first quarter of 2026, BYD reported revenue of 150.23 billion yuan — a decline of nearly 12% year over year. Net profit plunged more than 55% to 4.08 billion yuan, while operating cash flow shrank from 8.58 billion to 2.79 billion yuan, which the company attributed to weaker cash inflows from ongoing operations. The pressure has not stopped BYD from investing heavily: capitalised development spending rose to 8.29 billion yuan in the quarter, a clear signal that management is betting on technology as the route out of the current slump.
Should investors sell immediately? Or is it worth buying BYD?
Export markets are providing a critical buffer. In April alone, BYD shipped 135,098 vehicles overseas, helping to offset the domestic weakness. The company’s installed battery capacity reached 20.977 gigawatt-hours in April and 81.192 GWh in the year to date, including stationary energy-storage applications. Its strength in lithium-iron-phosphate cells — which command more than 80% of the Chinese market — remains a structural advantage.
It is against this backdrop that BYD will hold its “Ganwei” conference on Wednesday, May 28, at 7:30 p.m. Beijing time, streamed via official platforms. The event is designed to reframe the narrative around vehicle intelligence: ADAS, AI-powered driving functions and automotive software. No specific models or technical parameters have been announced; the focus is on the broader theme of “intelligentization”.
The data foundation BYD will point to is substantial. Its vehicles equipped with driver-assistance features have surpassed 2.99 million units, generating more than 190 million kilometres of usable driving data each day. That data feeds cloud simulations and reinforcement-learning models. Since 2025, BYD has launched smart-driving versions for more than 20 models. The Ganwei event follows earlier technology milestones this year, such as the second-generation Blade Battery and a new flash-charging system unveiled in March.
BYD at a turning point? This analysis reveals what investors need to know now.
The market will now judge whether BYD can translate its vertical strength in batteries and powertrains into credible progress on the software front. If the conference delivers concrete advances in ADAS and connected-vehicle functions, the technology theme could gain real traction as a growth driver for the stock. If it yields little more than strategic declarations, the operational headwinds — shrinking market share in batteries, falling domestic sales and compressed profits — will almost certainly dominate the conversation in the months ahead.
