BYD

BYD is known for it’s cars. BYD and its FinDreams battery arm also build Blade cells and packs for buses, trucks, forklifts, grid and residential storage, and – as of a 2026 announcement – marine vessels.

Buses and Trucks

BYD’s bus business predates Blade. The K9, one of BYD’s earliest electric buses, used an LFP pack built from three separate 108 kWh modules mounted on the roof, giving around 250 km of range. In September 2022 BYD brought Blade to buses with the eBus Blade Platform shown at IAA Transportation in Hannover, replacing that roof-mounted module arrangement with a chassis-integrated pack. On the truck side, the Class 8 8TT and the 6F are offered with 422 kWh or 563 kWh LFP packs aimed at drayage, regional haul and distribution work. BYD’s “heavy truck pressure test” – a fully loaded 46-tonne truck driven over the pack – is a manufacturer safety claim rather than an independently verified result, worth flagging if it’s repeated elsewhere.

Industrial Vehicles

BYD’s forklift range runs on an 80V LFP pack, vertically integrated with BYD’s own charger and motor, marketed on around seven hours of run time from a one-hour charge. It’s a smaller-volume business than the car or bus side, but a genuinely different duty cycle from anything else in BYD’s LFP lineup: repeated deep partial cycling across a single shift rather than a daily commute.

Stationary Storage

On the grid side, BYD Energy Storage’s MC Cube launched in May 2023 as the first BYD product built on Blade cells, using a module-less “Cell to System” (CTS) approach – the same pack-level thinking as Cell to Pack, just applied at container scale. The 2024 follow-up, MC Cube-T, raised cell and cube energy capacity by up to 11% and total system capacity by up to 35.8% over that first generation, with up to a 24.7% smaller footprint. On the residential side, the Battery-Box range (HVS, HVE, HVB, LV Flex) is built from 2.56-4.29 kWh modules stacked into towers from roughly 5-23 kWh; the HVB, launched May 2025, is the first Battery-Box generation to use Blade cells rather than earlier module formats. See the site’s Battery Energy Storage Systems page for more on BESS testing, standards and failure modes.

Marine

In May 2026, BYD Energy Storage and Norway’s Corvus Energy signed a strategic cooperation agreement to co-develop LFP battery systems for electric vessels, with BYD contributing cell technology and manufacturing scale and Corvus handling marine system integration and certification. It’s BYD’s first publicly announced move into maritime, with no shipped product yet.

Manufacturing Scale and Sodium-Ion

FinDreams also supplies cells outward to non-BYD pack builders: an eight-year agreement signed with BorgWarner in February 2024 sees FinDreams-supplied Blade cells assembled into LFP packs across Europe, the Americas and parts of Asia-Pacific, and FinDreams is reported to supply cells for Tesla’s Shanghai Megafactory. Total BYD battery production reportedly reached 194.8 GWh in 2025, though that figure comes via secondary trade press rather than a primary BYD filing and is worth tracing further before treating as a hard number. Alongside its LFP business, FinDreams holds 51% of a joint venture with Huaihai Holding Group building a 30 GWh/year sodium-ion plant in Xuzhou, construction of which began in January 2024 – see the site’s Sodium-Ion Battery page.

2019

• FinDreams is formed as a subsidiary of BYD and contains the sub-components: power batteries, automotive lighting, electronics, powertrain, and moulding.

2020

2021

• e-Platform 3.0 – vehicle platform that takes the Blade technology to the next level with a Cell to Body approach.
  • Seal
  • Seal U

2022

• FC4680P – 15Ah LFP cylindrical cell in the Tesla 4680 cylindrical format.
• eBus Blade Platform – shown at IAA Transportation in Hannover in September 2022, bringing Blade to buses with a chassis-integrated pack, replacing the roof-mounted module arrangement used on the earlier K9.

2023

• MC Cube – BYD Energy Storage’s first energy storage product built on Blade cells, launched May 2023. Uses a module-less “Cell to System” (CTS) approach, the same pack-level thinking as Cell to Pack applied at container scale.

2024

• Shark PHEV – 29.58 kWh Blade battery pack.
• e-Platform 4.0 – likely to be the basis for the electric vehicles from the end of 2024.
• BorgWarner supply deal – an eight-year agreement, signed February 2024, for FinDreams to supply Blade cells that BorgWarner assembles into LFP packs across Europe, the Americas and parts of Asia-Pacific.
• MC Cube-T – second-generation containerised energy storage system, launched April 2024, raising cell and cube energy capacity by up to 11% and total system capacity by up to 35.8% over the first MC Cube.
• Sodium-ion joint venture – FinDreams and Huaihai Holding Group began construction of a 30 GWh/year sodium-ion plant in Xuzhou in January 2024, with FinDreams holding 51% of the venture.

2025

• BYD have stated “Oil and electricity at the same speed”, by this I read: Charging at the Speed of a Petrol Pump. What does that mean in terms of power?
• Battery-Box HVB – launched May 2025, the first generation of BYD’s residential Battery-Box range to use Blade cells rather than earlier module formats.

2026

• BYD Blade 2.0 – introduced in March 2026
  • BYD Blade 2.0 compared to 1.0 – a move from LFP to LMFP
  • BYD battery self heating system – in the Denza Z9 GT means that even in cold conditions it just adds 3 minutes to the charge time. 
• BYD-Corvus marine MoU – BYD Energy Storage and Norway’s Corvus Energy signed a strategic cooperation agreement in May 2026 to co-develop LFP battery systems for electric vessels.
