Do you Build AI Models?

Train them with batemo!

Challenge

The development of data-driven artifi­cial intel­li­gence (AI)-models or algorithms such as neural networks (ANN) or support vector machines (SVM), which use machine learning techniques to learn the linkage between battery in- and output variables, is an exciting but challenging task. It means to create a model that captures the non-correl­a­tive, non-linear and dynamic behavior of a real battery cell by supplying large amounts of data for AI training. Ensuring that the training data are of high quality and cover all operating conditions is essen­tial for building robust AI models. Something that is missing when technology evolves fast – like in the battery business with novel chemistries that all have their own challenges. 
The major problem is that fast, physical and accurate battery models are missing for AI development. As alter­na­tive, testing-based workflows are applied. However, conducting suffi­cient exper­i­ments at the time when the datasets are needed for training is close to impos­sible, as it is expen­sive and time-consuming. This causes major issues when the algorithm trans­fers data deficien­cies to inaccu­rate predic­tions, non-inter­pretability and unsafe opera­tion.
This is true for many aspects of AI development. Let’s make some examples: 
  • Does my AI algorithm track the state of charge correctly, even under extreme conditions?
  • How accurately does my AI estimate the state of health?
  • How do I ensure that my AI is not biased from imbal­anced battery training datasets causing over- or underfitting?
  • How can my AI generate inter­pretable results that provide insights into the physical battery state?
  • How do I know if I fed suffi­cient data so that model predic­tions are robust?
Finding reliable answers to these questions fast is diffi­cult… very difficult. 

Solution

You need the ultimate tool for devel­oping your data-driven AI algorithm by giving it access to the best possible data base for training and valida­tion. This is exactly what the Batemo Cell Models can do for you. Batemo’s unique battery modeling technology allows you to develop advanced AI algorithms based on globally validated battery cell models. The under­lying idea is to develop your AI not with measure­ment data, but with the most accurate battery cell models there are. With the Batemo Cell Model as high-fidelity physical core model, you ensure that every­thing during AI development holds true when you move to field opera­tion. By having access to the Batemo Cell Model Library, you ensure that the training of your AI algorithms is consis­tent and robust amongst all your cell types, and that you have the ideal training source for all your cells from day one. By incor­po­rating the Batemo Cell Models into your development, you can unlock the full poten­tial of data-driven approaches to build better AI algorithms with less resources a lot faster.

Physical

The Batemo Cell Models are strictly physical and provide access to inner cell quanti­ties. Only if you base your AI development on a physical core model that correctly splits up the under­lying processes, you can enable the AI to predict the perfor­mance of fresh and aged battery cells under all operating conditions.

Accurate

The Batemo Cell Models are the most accurate battery cell that exist on the market - guaran­teed! We always demon­strate the validity through exten­sive measure­ments that prove highest accuracy. Only in this way you can ensure that the AI receives validated cell behavior as data base. 
The method­ology we apply is novel and robust and repre­sents a paradigm shift in AI development. It is based on syner­gis­ti­cally combining physics-based Batemo simula­tions, data-driven machine learning algorithms, and testing.
