Battery Modeling and Simulation

efficient battery development needs
reliable modeling techniques.

Technology

Building good batteries is a very difficult task: The behavior of batteries is notoriously complex as a myriad of physico-chemical processes are taking place at the same time, and the requirements in the various applications of batteries are highly diverse. Fortunately, there is a solution to cope with this complexity: simulation-based development.

Battery modeling and simulation provides a deep understanding of the battery behavior and speeds up system development while coping with the high complexity and variety of variants.

But there is a problem: Battery cells are very difficult to model, and the available models do not work sufficiently well.

Let’s make this more clear:

Equivalent circuit models (ECM) mimic the terminal behavior of the cell using simple elements. Because the fundamental model structure does not match the cell physics and since nonlinearities are not properly considered, ECMs are too inaccurate.

On the other hand, finite element method (FEM) tools are prone to errors, parameterization takes several months and the model validity must be ensured by you. This makes the FEM approach too complex and too slow for development.
And that’s the challenge: developing batteries is an extremely difficult task…

..‌.until Batemo’s technology fundamentally changed that!

We developed a novel model technology, which is not an ECM model, not an FEM model, but which is something else:

Fast

batemo cell models run within seconds on office computers, making them provide results in rocket speed with easy handling and visualization. Waiting for a simulation result for hours or even days is a thing of the past.

Physical

batemo cell models do not simply mimic cell behavior, but precisely describe all electrical, chemical, and thermal processes inside the cell. This is true even under extreme conditions when conventional models fail.

Accurate

batemo cell models have proven validity in the total current, temperature and SOC regime of the cell, since accuracy is a prerequisite for simulation-based development. This is why the our models are gloablly validated.

This the what makes our models unique, and what we promise to our customers: Our models are fast, physical, and accurate. It’s part of our DNA to not rely on claims without back-up, so we gurantee:

Guranteed: Batemo Cells are the
most accurate battery models on the market.

If you can show us another battery cell model that is more accurate, we will refund your money!

The model accuracy is calculated from a set of validation experiments that cover the total operational area of the cell as specified by the cell manufacturer. Additional validation measurements in the interpolation and extrapolation regime, that are unknown to the model creator, are used for additional testing of the model. The ratio of the measurement time between the different validation sets is as follows: validation set known to Batemo and competitor 50%, validation set known only to Batemo and unknown to competitor 25%, validation only know to competitor and unknown to Batemo 25%. Model accuracies are defined and averaged as defined in the Batemo validation Excel documents.
