Cells Designed for Every Application

Freudenberg e-Power Systems is a leading supplier of lithium-ion cell technology. Our reliable and long-lasting power cells are suitable for a wide range of heavy-duty applications, such as trucks, buses, maritime, construction, agriculture, and mining. When developing our power cells and improving their performance, we always focus on meeting the diverse needs of our customers.

Our XPAND pack, with integrated power cells, is ideal for maritime applications and certified to DNV GL, Lloyd’s Register, and other industry standards. This ensures the pack is resistant to vibrations, shocks and impacts, while preventing thermal runaway propagation.

  • High-capacity cells
  • Reliability and safety
  • Low total cost of ownership

Cells and Packs from a Single Source

From state-of-the-art materials to cell formulations and processing, we design and build our power cells with the longest possible lifetime at high charge rates. Working closely with our suppliers, we select and develop materials that provide the right balance of energy density, power, stability, safety, and cost. They are tested extensively on thermal, chemical, and electrical validation levels.

This testing is integrated into our pack development, where we subject our cells and packs to real-world scenarios, including abuse, years-long operation, and lifetime modeling. The rigorous testing regiment applied to every cell we design, and the invaluable knowledge gained from this testing, strengthens our development efforts to produce robust and long-lasting packs.

Safe and Reliable Power

Our power cells have a mid-nickel NCM-523 cathode chemistry. For power applications where safety and charge rate outweigh the need for energy, we have co-developed with Ascend Elements a 100% recycled custom cathode material tailored to heavy-duty markets, with best-in-class thermal stability and cycle life compared to market benchmarks.

Our extensive testing and validation, along with intelligent cathode chemistries, ensure our power cells can safely and reliably supply a high level of energy over a long period of time. This in conjunction with our proven battery management system ensures the highest level of safety for our battery packs.
