ABB Explains – traction batteries

Industry is being swept by an unstoppable trend: electrification. Going electric enables higher energy efficiency as well as cleaner and more sustainable operations. Batteries are an integral part of this process.

The battery assemblies made by ABB are far larger than those used in cars. They use a modular concept, meaning they can be tailored to virtually any high-power application. They are used (among others) in mining trucks, locomotives, railway maintenance vehicles, and other special-purpose machines.

Discover ABB’s battery manufacturing

Produced in Baden, Switzerland, ABB’s batteries are modular. Cells are assembled into modules, and modules into battery packs. The high-precision process uses laser welding, advanced electronics, and extensive testing to ensure safety and reliability. Key performance parameters of the batteries include energy capacity, very fast charge and discharge capability (high C‑rates), and an exceptionally long cycle life, often tens of thousands of cycles - far beyond automotive batteries.

ABB’s batteries primarily incorporate  LTO (lithium titanate oxide) cell chemistry, which sacrifices energy density and range in exchange for extreme durability, fast charging, safety, and robustness. LTO batteries are resistant to thermal runaway, tolerate high temperatures, and are well suited for demanding environments such as mining, rail, and industrial logistics. Water-based thermal management enables high power operation without overheating.

The batteries support both fully electric and hybrid systems. Hybrid solutions allow immediate fuel savings – a reduction of around 20 percent in diesel consumption - without requiring the installation of charging infrastructure. They act as a transitional technology, helping industries gain experience with batteries as the infrastructure for full electrification is being built.

ABB continues to improve battery energy density. This includes monitoring and evaluating next-generation materials such as niobium-based and sodium‑ion technologies. As production scales, performance improves and costs decline, supporting broader adoption across industrial, transportation, and energy‑intensive applications such as data centers and warehouses.
