Batemo digitizes battery development.
For a sustainable and joyful life.
The most accurate battery simulation models. Guaranteed.
Batemo is the global technology leader for the development of lithium-ion battery simulation software. We combine the three technological assets of battery modeling, battery parameterization and battery data, which makes our products unique worldwide. We have had hundreds of battery cells in our lab, measured them over the entire operating range, completely disassembled and modeled them. This is why we were able to develop an entire library of the most accurate battery cell models, the Batemo Cell Explorer:
Discover an entire library of battery cell models of all different formats, sizes and chemistries.
To enable the consistent simulation-based development of batteries, our technology fulfills three criteria:
Fast
Our solutions provide results in rocket speed with easy handling and visualization. Waiting for a certain result or output over days is a thing of the past, allowing you to act as fast as possible in the rapidly changing market.
Physical
Our battery cell models are strictly physical, which means that all processes in the battery are described by physical equations, and that all battery information we offer are based on measurements in our lab.
Accurate
A prerequisite for simulation-based development is to build on models, parameters and data that are accurate. This is why we alwalys demonstrate the global validity of our models, and why we have high-quality test stands.
This is what we promise to our customers: Everything we do is as fast, as physical and as accurate as possible. Since it is part of Batemo’s DNA to not rely on claims or punchlines without a back-up, we condense that in a guarantee:
If you can show us another battery simulation model that is more accurate, we will refund your money.
show the rules
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.
