Select the right battery cell & technology

Challenges
  • Different cells suit different applications
  • Datasheets from cell manufacturers do not provide a complete picture of battery behavior
  • Testing all available cells for specific use cases to obtain aging data is too cost-intensive
Solution
  • Access the performance and aging behavior of the battery cell for different use cases over its lifetime. Validate the information provided by cell suppliers.
  • Simulate hundreds of different use cases in no time to make sure the strengths and weaknesses of your chosen cell are well-understood.
  • Compare battery cells to choose the optimal supplier.

 

Get battery design spot on

Challenges
  • When developing a new battery system, the space for the battery should be used as efficiently as possible.
  • The battery design must ensure safe operation over it’s entire lifetime.
  • Depending on the configuration, for the same load profiles, battery cells are loaded differently and therefore degrade differently.
Solution
  • Avoid the cost of oversizing, but do not compromise on performance or lifetime.
  • Identify the optimum number of cells and what the right configuration is needed to meet the power requirements of the application.
  • Simulate different use cases and designs to strike the balance between desired performance and optimal costs.

 

Fine-tune battery system design

Challenges
  • Assessing the interaction of different components for the overall system.
  • It is time- and cost intensive to assess the impact of different use cases on battery performance in varying operating conditions.
  • Currently only generic battery models available which insufficiently model the behavior.
Solution
  • Enhance the model-based design of your application by integrating validated battery models with the system simulation. Evaluate how its requirements translate into battery requirements to find the best concept.
  • Run sensitivity analysis on different parameters such as SoC windows or DoD to find the optimal operating conditions for a long-lasting and reliable vehicle.
  • Use these insights to optimize Battery Management System functionalities, derive warranty terms, and assess business cases such as BaaS.
