 This dataset contains information about the duty cycle of an electric vertical take-off and landing aircraft. It consists of 22 batteries, each with different characteristics such as charge current, discharge power, discharge duration, ambient cooling conditions, and end-of-charge voltage. This data can be used to train machine learning models, fit physical, or empirical models for battery performance and or degradation, and more. This article was offered by Alexander Bills, Shashank Shripad, Lee Fredericks, and others.
