BYD Blade Batteries Power Industrial Trains in New Deal 2026

BYD's famous blade batteries are now moving from electric cars and trucks to industrial trains, thanks to a new agreement between its subsidiary FinDreams Battery and Chinese company Changsha Fusheng Technology. The deal, signed on September 7 at BYD's Shenzhen headquarters, marks another step in the expansion of BYD's battery technology beyond passenger vehicles.

What the BYD-FinDreams Deal Covers

The agreement focuses on industrial locomotives used in mines and factories for tasks like internal transport. While the exact contract value, supply volumes, specifications, and delivery dates were not disclosed, the partnership aims to integrate BYD's blade batteries into these specialized vehicles.

FinDreams Battery will handle research, development, and manufacturing of the batteries, while Changsha Fusheng will integrate them with the necessary control and management electronics for railway operations. Notably, despite being used in trains, these will be automotive-grade batteries.

Why This Matters for BYD's Battery Business

The deal comes at a time when BYD is losing ground in its battery business. According to Car News China, BYD installed 72 GWh of EV batteries in China this year, capturing an 18% market share—down 13% from the same period last year. This decline suggests the company is seeking new applications for its battery technology to maintain growth.

Industrial trains represent a niche but potentially lucrative market for BYD's blade batteries, which have already proven their performance, fast-charging capabilities, and reliability even in extreme cold. By diversifying into this sector, BYD can leverage its expertise in battery manufacturing while reducing dependence on the highly competitive EV market.

Key Takeaways from the Partnership

• BYD's blade batteries will be used in industrial trains for mining and factory applications.
• FinDreams Battery leads R&D and manufacturing, while Changsha Fusheng handles system integration.
• The batteries are automotive-grade, not specially designed for rail.
• The deal comes as BYD's EV battery market share declines in China.
• No financial details or supply volumes were disclosed.

BYD's Battery Market Position

BYD has long been a major player in the battery industry, but recent data shows it facing increased competition. The drop in market share from 31% to 18% year-over-year indicates that rivals are catching up, particularly in the Chinese EV market.

This partnership with Changsha Fusheng could help BYD tap into new revenue streams and demonstrate the versatility of its blade batteries. Industrial applications often require robust, reliable power sources, and BYD's proven track record in automotive batteries could give it an edge.

What to Watch Next

While the financial details remain undisclosed, the success of this partnership will depend on how well BYD's automotive batteries adapt to the rigorous demands of industrial train operations. If successful, it could open doors for BYD to supply batteries for other heavy-duty applications, such as construction equipment or marine vessels.

Additionally, as BYD works to regain its battery market share, this diversification strategy could be a test case for other EV battery makers looking to expand beyond the automotive sector. The industrial train market, though small, offers a proving ground for battery durability and performance in harsh environments.
