Jointly Learning Consistent Causal Abstractions Over Multiple Interventional Distributions

1 code implementation14 Jan 2023 Fabio Massimo Zennaro, Máté Drávucz, Geanina Apachitei, W. Dhammika Widanage, Theodoros Damoulas

An abstraction can be used to relate two structural causal models representing the same system at different levels of resolution.

State of Health Estimation of Lithium-Ion Batteries in Vehicle-to-Grid Applications Using Recurrent Neural Networks for Learning the Impact of Degradation Stress Factors

no code implementations16 May 2022 Kotub Uddin, James Schofield, W. Dhammika Widanage

This work presents an effective state of health indicator to indicate lithium-ion battery degradation based on a long short-term memory (LSTM) recurrent neural network (RNN) coupled with a sliding-window.

Feature Analyses and Modelling of Lithium-ion Batteries Manufacturing based on Random Forest Classification

no code implementations10 Feb 2021 Kailong Liu, Xiaosong Hu, Huiyu Zhou, Lei Tong, W. Dhammika Widanage, James Marco

Lithium-ion battery manufacturing is a highly complicated process with strongly coupled feature interdependencies, a feasible solution that can analyse feature variables within manufacturing chain and achieve reliable classification is thus urgently needed.

Systematic derivation and validation of a reduced thermal-electrochemical model for lithium-ion batteries using asymptotic methods

1 code implementation3 Nov 2020 Ferran Brosa Planella, Muhammad Sheikh, W. Dhammika Widanage

These models are usually posed in an ad hoc manner, leading to inconsistencies with the DFN model and to multiple formulations of the same model, with the Single Particle Model (SPM) being a very good example of the latter.
