Internship | Battery Remaining Useful Life Prediction

During your thesis you will be estimating the remaining useful life of lithium ion batteries by combining a machine learning algorithm with a model. The research revolves around implementing a model based battery ageing estimation and integrating it with the existing data driven estimation. The downside of the data driven estimation is that it requires data to function. By integrating it with a model based method, the algorithm is able to provide an estimate without any prior data, yet will still improve the estimate over time as more data becomes available, taking advantage of both methods’ strengths. Your job is to research the advantages and disadvantages of combining the two methods.

Your thesis will give a valuable contribution to TNO’s ambition to create a remaining useful life algorithm for batteries. Specifically by bringing the theory closer to practical implementation. A remaining useful life algorithm supplies battery owners with an estimate of how long their battery will last. Knowing how long the battery will last allows the owner to prove the resale value to a potential buyer, resulting in a lower battery cost over time and improves the chances batteries are reused in other applications prior to being scrapped/recycled.

Assignment tasks:

• Implement a model based remaining useful life algorithm and integrate it with the existing data driven algorithm.
• Test the combined algorithm.
• Analyze the combined algorithm’s performance/ feasibility and suggest possible improvements.
