Stage | Battery Remaining Useful Life Prediction

WHAT WILL BE YOUR ROLE?

During your thesis you will be estimating the remaining useful life of lithium ion batteries using a machine learning algorithm. The research revolves around studying the effects of real world imperfections in the data on the performance of the algorithm. Even though there is numerous sources in literature describing remaining useful life methods, few actually can cope with the imperfect nature of real world data. Your job is to manipulate an extensive battery ageing dataset to mimic real life imperfections and research the impact on the algorithms performance.

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:

• Use machine learning to create a battery remaining useful life estimation algorithm and determine the baseline performance.
• Manipulate data and incrementally add realistic imperfections into the data to investigate the effect on algorithm performance.
• Suggest methods to mitigate inaccuracy caused by the imperfections introduced.
