Cell Qualification

Find the best cell for your application


  • Different cells suit different applications
  • Datasheets only provide an incomplete picture of the battery behavior
  • Testing all available cells for specific use cases is not feasibile



  • Instantly download a wide range of cell models
  • Virtually test performance and lifetime for different cells in specific use scenarios to identify ideal cell

Battery System Design

Avoid oversizing


  • Battery performance requirements must be met
  • The battery design must ensure safe operation over the entire lifetime
  • Difficult assessment of impact of different use cases of battery performance over lifetime



  • Virtually test different use cases & configurations to find the optimal system design and meet requirements
  • Simulate different use cases and designs to strike the balance between desired performance and optimal costs

Application Design

Develop better battery systems


  • Assess the interaction of different components for the overall system
  • Deduct optimal component requirements
  • Currently only generic battery models available which insufficiently model the behavior



  • Use a parametrized battery model in the overall system simulation
  • Virtually test interdependencies to derive system requirements more accurately
