State of Health Estimation of Large-Capacity Energy Storage Batteries Based on Mechanical–Electrical–Thermal Multi-Modal Features

This paper proposes an SOH estimation method that fuses mechanical–electrical–thermal multi-modal features by introducing expansion force monitoring. Aging tests on 16 prismatic 530 Ah LiFePO4 batteries from two brands are conducted at 25 and 45 °C. Each full cycle is divided into charge, post-charge rest, discharge, a...
