EV Lithium Ion Battery State of Health Dataset

Each sample includes information about the battery’s operating conditions such as voltage, current, temperature, and elapsed test time. From these measured values, additional attributes including Δt, Current Modified, Discharge (Ah).

These features together provide a detailed picture of the battery’s behavior during cycling, where voltage and current reflect the instantaneous operating conditions, test time and Δt capture the temporal progression, and the Discharge (Ah) gives an indication of the total charge throughput. Collectively, these attributes form the foundation for accurate estimation of SOH and enable understanding of how the battery degrades over time.
