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.
