SoH estimation of Lithium-ion battery

  • This project is designed to predict State of health (SoH) for identifying remaining useful life of Li-ion batteries.
  • Linear Regression, LSTM
  • Nov. 1, 2020 ~ Dec. 1, 2020

| Plan | Presentation |

Project for the Industrial Mathematics & Lab Course

  • This repo is maintained by 오서영, 조지수, 이윤녕, 정유은

Process

1. Calculating and Visualizing SoH with 7 Li-ion battery datasets | Code


2. Eliminating outliers with quantile | Code


3. Linear Regression | Code

  • Start at 50% Cycle

  • Start at 70% Cycle

4. Long Short Term Memory | Code

  • Start at 50% Cycle

  • Start at 70% Cycle
