EVs are extensively utilised with lithium-ion batteries. Predicting the SOH of batteries is desired to achieve optimal operation and health management. The most significant obstacle to accurately predicting battery health is choosing battery features. This study introduces numerous data analysis strategies to manage feature irrelevancy and help determine which features can be selected and used in real-time and edge computing. The first step in manually crafting features is to analyse the evolution pattern of numerous essential battery characteristics. Second, the correlation between selected features and degraded capacity was analysed. Then, selected features are fed into a representative machine learning regression model to effectively predict the remaining capacity of the battery to find the SOH status. Finally, the remaining battery capacity is selected as a feature to predict the RUL in terms of remaining charge-discharge cycles.
