We specialize in high-precision simulation software for lithium-ion-batteries. For any lithium-ion-cell we create physical models and demonstrate global validity. We call our models Batemo Cells. They help to solve central challenges of battery system development and answer typical design questions such as:
- Which cell technology is most suitable for a specific application?
- What does an optimal pack design look like?
- Which operational strategy extends the lifetime of the battery?
- How can innovative fast charging methods be developed?
- How can safety be guaranteed in complex systems, under all circumstances?
inaccurate and no insights
Equivalent circuit models (ECM) mimic the terminal behavior of the cell by simple elements like resistors, capacitors or other impedance elements. The model parameters are usually multi-dimensional lookup-tables obtained from measurements. Because the fundamental model structure does not match the cell physics and since nonlinearities are not taken into account properly, ECMs are inaccurate and do not allow an insight of the cell.
Using finite element method (FEM) tools, the microstructure of the electrodes is recontsructed and the system of partial differential equations is solved spatially. The approach is error-prone, parameterization takes several months and model validity must be ensured by you. Moreover, simulation times are in the range of many hours. This makes the FEM approach too complex and slow for industrial development.
complex and slow
You can use our Batemo Cells as digital twins and save time-consuming and lengthy measurements. Your battery system development becomes model-based, making it faster, safer, more flexible, and leading to better products. This is how we contribute your success.
With Batemo Cells, the innovation potential of new ideas can be easily evaluated and complex functions can be developed much quicker. This is how you can enhance your technological leadership.
You can monitor your batteries during operation. You can develop the safety features with Batemo Cells, detect critical conditions early, and design efficient strategies to ensure safe operation under all conditions.
Battery packs are often used in a variety of products with different chargers. Using Batemo Cell simulations, you can ensure overall compatibility.
If you are introducing new technologies to the market, the Batemo Cells helps you to bring high-quality, innovative ideas to the market very quickly. Key product features can be improved and differentiated from competitors, leading to increased market share.
Batemo Cell simulations are significantly faster than real-time laboratory tests. You can perform comprehensive, simulation-based test scenarios with single cells, battery packs, or total systems in a fraction of time.
With Batemo Cells, single functions or subsystems can be thoroughly tested in the early stages of the development process. You can detect design errors early on and significantly reduce the failure rate of your design and production validation.
Batemo Cells reduce the cost of battery system development in many ways. For instance, you can reduce expenses on prototyping, avoid performing extensive lab measurements, and decrease your development time.
