BYD Battery Platforms

Blade · FinDreams · Super e-Platform · MC Cube

BYD installed 194.8 GWh of EV batteries in 2025, second only to CATL, and most went into its own vehicles. Because BYD builds both the cell and the vehicle, it carries the producer obligations that CATL usually shares with an automaker.

FinDreams Battery, a BYD subsidiary, makes Blade LFP cells in a cell-to-pack design, including the flash-charge cells of the Super e-Platform. Its output flows mostly to BYD itself: BYD cars (Dynasty, Ocean, Denza, Yangwang), buses, trucks and forklifts including the Lancaster, California plant, and grid storage systems MC Cube-T and Haohan. Outside buyers include Tesla's Berlin-built Model Y, Toyota and Xiaomi. The Super e-Platform launched in 2025 runs at 1,000 V with up to 1,000 kW peak charging and a 10C cell charge rate.

Finding

BYD is the only top-tier battery maker that consumes most of its own output, which makes it both cell supplier and producer of record across cars, buses and grid storage

SNE Research put BYD's 2025 EV battery installations at 194.8 GWh, 16.4% of the market. FinDreams Battery makes Blade LFP cells for BYD, Denza, Yangwang and Fangchengbao vehicles and for outside customers including Tesla's Grünheide-built Model Y, Toyota's China-market bZ3 and Xiaomi's SU7.

The Blade is a long, thin LFP prismatic cell laid directly into the pack as a structural member, which raised LFP pack energy density enough to replace NMC in most mass-market cars. The Super e-Platform, launched in March 2025 on the Han L and Tang L, pairs 1,000 V electronics with flash-charge Blade cells for up to 1,000 kW peak charging, and BYD is building its own megawatt-class charger network in China to use it. The same cells go into BYD's electric buses and trucks, forklifts and terminal tractors, and its MC Cube-T and Haohan grid storage containers.

Vertical integration changes who is accountable. When BYD sells a car or a bus in the EU, it is the battery producer for the passport, carbon footprint and take-back duties, not just the cell supplier. In the US, Section 301 tariffs on Chinese EVs and batteries keep BYD cars out, and federal transit funding rules bar buses from Chinese state-linked makers, which cut BYD's Lancaster bus plant off from most transit agency orders.
