Top power battery suppliers

According to data compiled by the Gasgoo Automotive Research Institute, the power battery market for the Jan.-Apr. 2025 period shows a high level of concentration. The top 10 suppliers collectively account for nearly 95% of the China's local market share, highlighting the increasingly prominent dominance of leading players.

CATL secures the top position with a 41.6% market share (58,872 MWh installed). Leveraging its strong technological capabilities and large-scale production, CATL has built a comprehensive supply network that covers major carmakers, reinforcing its solid market leadership.

FinDreams Battery ranks second with a 27.1% market share (38,325 MWh installed). Backed by BYD's strong vertical integration, the company has established solid technological barriers in the lithium iron phosphate (LFP) segment and maintains stable growth through long-term partnerships with multiple leading Chinese carmakers.

CALB ranks third with a 6.5% market share (9,196 MWh installed). By pursuing a differentiated product strategy, the company has gained solid traction in both premium passenger vehicles and energy storage, steadily strengthening its position in the market.

Gotion High-tech captures 4.8% of the market (6,737 MWh installed), standing out in A00-segment electric vehicles (EVs) and energy storage through its focus on cost-efficient technologies.

The competitive landscape of the power battery market has settled into a "two giants followed by several strong players" structure: CATL and FinDreams Battery together secure nearly 70% of the market, reinforcing a duopoly. Meanwhile, other companies compete for the remaining share through technological innovation, client expansion, and cost optimization in niche segments. The high concentration among the top 10 suppliers highlights the industry's significant technological barriers and capital intensity, indicating that future competition will further consolidate around leading players, potentially accelerating market restructuring.

Top power battery pack suppliers

The latest data on power battery pack installations by the Gasgoo Automotive Research Institute shows a rapid acceleration in original equipment manufacturer (OEM) vertical integration, with carmakers' in-house battery pack production now exceeding 50% of total market volume—signaling a deep restructuring of the power battery supply chain.

FinDreams Battery takes the lead with a dominant 32.5% market share (1,044,665 sets installed). Its leadership is driven by close integration within BYD-affiliated entities and reflects the strategic determination of OEMs to control core battery system integration technologies. CATL ranks second with an 18.9% market share (609,691 sets installed), highlighting the growing trend of leading power battery manufacturers shifting towards system integration.

Notably, the automakers—Tesla (5.1%/164,550 sets) and Leapmotor (3.3%/106,061 sets) — have rapidly emerged as prominent power battery pack suppliers. Tesla's entry into the top three and Leapmotor's breakthrough into the top ten highlight the growing trend of carmakers building their own power battery pack capacity to achieve end-to-end technological control. These companies are not just reshaping the traditional supplier landscape — they are also shifting the balance of profit distribution and bargaining power across the power battery supply chain.

The current market dynamics reflect a deeper shift in the NEV industry, where carmakers are increasingly competing for control over key components. With OEM-produced battery packs now surpassing 50% of total installations, it is clear that carmakers are taking power battery system design and cost management into their own hands. As electrification technologies continue to advance, this trend of vertical integration is expected to accelerate, signaling a broader shift from standalone component supply to integrated system solutions across the supply chain.

Top BMS suppliers

The battery management system (BMS) supplier rankings show a clear trend: carmakers are increasingly focusing on having direct control over BMS technology. This is strongly reflected in the market structure. FinDreams Battery ranks first with a 33.1% market share (1,065,842 sets installed). Its leading position comes not only from its technical strength but also from the growing strategy of carmakers to take control of key components.

As a global leader in the power battery sector, CATL has also demonstrated strong performance in the BMS market, securing the second place with a 15.6% market share (501,248 sets installed), highlighting not only the growing trend of top power battery suppliers expanding into system integration, but also carmakers' push to gain greater control over BMS technologies.

Notably, VREMT (8.7% / 278,483 sets) and Leapmotor (3.3% / 106,061 sets), either carmakers themselves or their affiliated companies, both secure leading positions on the list. Their strong performance highlights the growing push among OEMs to bring BMS R&D and production in-house, underscoring the urgent need for direct control over battery management technologies. Meanwhile, UAES captures a 3.3% market share with 105,691 sets, signaling that some carmakers are also choosing deep collaborations with traditional suppliers to retain influence over BMS technology.

The current market landscape highlights a key shift in the NEV supply chain. As competition in electrification deepens, BMS has become a critical battleground, with OEMs aiming to take control of this core technology to strengthen their competitive edge. The strong positions of FinDreams Battery, CATL, and VREMT epitomize this clear industry trend. Looking ahead, OEMs' demand for BMS autonomy is set to grow, pushing suppliers to open up their technologies and driving OEMs to increase their own R&D efforts—reshaping how the BMS market will compete in the future.
