结论摘要
行业媒体对第三方机构旧数据的综述：比亚迪国内电池份额降、海外份额升，净方向MIXED且无新增边际事实，对任何单一标的均不构成可交易催化，回避。

主要风险
- 国内动力电池价格战与比亚迪国内份额持续流失若在后续季度数据中确认，可能形成趋势性利空，但本报道数据非新增
- 海外高增长为多家中国电池厂共享的行业beta，个股选择仍需新订单/定点等公司层面催化
反向证据
先例如何影响了这次决策
对本次决策的影响:未据此交易；行业第三方例行装机统计通常在发布当日被板块整体消化，二次媒体汇编不产生独立价格反应
方向:无可对照先例，且事件本身为存量行业数据综述，缺乏事件研究所需的边际催化锚点
涨幅量级:不适用

BYD is facing declining market share in China's domestic electric vehicle (EV) battery market, even as its overseas business continues to expand, highlighting a growing divergence between its domestic and international performance.
According to data from the China Automotive Battery Innovation Alliance (CABIA), BYD's domestic power battery installations totaled 106.44 GWh in the first three quarters of 2026, down 4.3% year over year.
Its market share fell to 18.53%, a decline of 4.04pp from the same period in 2025. BYD remained China's second-largest power battery supplier, behind market leader CATL.

Overseas installations jump 66.5%
In contrast to its domestic performance, BYD's overseas battery business has maintained strong growth.
Citing data from South Korean market research firm SNE Research, Chinese media outlet Battery Network reported that BYD's overseas power battery installations reached 39.7 GWh in the first eight months of 2026, representing a 66.5% year-over-year increase.
Its overseas market share climbed to 11% from 8.2% in the same period of 2025, placing the company third in the overseas market.
BYD's expansion across Europe, Southeast Asia, and South America has become a key driver of its growing overseas battery installations.
Because BYD primarily supplies batteries for its own electric vehicles, the company's vehicle sales performance directly affects demand for its batteries and their installation volumes.
According to company data, BYD sold a cumulative 3.1316 million new energy vehicles (NEVs) in the first three quarters of 2026, down 3.94% year over year.
However, NEV exports reached 180,700 units in September, accounting for 38.98% of the company's total vehicle sales that month.
That proportion increased by approximately 21pp from September 2025, underscoring the growing contribution of overseas markets to BYD's overall vehicle sales.
Chinese peers accelerate overseas expansion
BYD is not alone in benefiting from international demand, as overseas markets have also become increasingly important to other Chinese battery manufacturers.
According to SNE Research, several Chinese battery suppliers recorded triple-digit growth in overseas power battery installations during the first eight months of 2026.
Gotion High-Tech reported a 147.2% year-over-year increase, while EVE Energy recorded growth of 185.6%. SVOLT Energy Technology's overseas installations rose 105.2%, and CALB registered a 77.6% increase.
During the same period, the combined overseas market share of six Chinese companies among the world's 10 largest power battery suppliers increased from 43.6% to 56.2%, reflecting the growing presence of Chinese battery manufacturers in international markets.
