Description
This dataset contains locally acquired single-cell LG 18650 NMC battery data collected under UDDS-style dynamic operation, CC/CV charging, rest periods, and reference performance tests. It includes voltage, current, temperature, charge throughput, SOC, sparse measured/reference capacity, and sparse SOH labels.
The experiment used a Rigol DP711 programmable DC power supply for charging and a Rigol DL3021 DC electronic load for discharge, dynamic-load operation, and reference-discharge operation. A surface temperature probe was attached to the 18650 cell casing during testing.
The dataset is intended as a local target dataset for public-to-local transfer evaluation in lithium-ion battery state-of-health estimation and embedded-BMS second-life battery research. The released file contains one local cell and should be interpreted as a reproducibility dataset for target-domain evaluation, not as a population-scale aging dataset.
Current sign convention: positive current is discharge and negative current is charge.
SOH and capacity labels are sparse and mainly associated with reference-discharge-related rows. The first reliable 100% SOH capacity in the file is approximately 3.219 Ah. Experiments using this dataset should explicitly state the reference-capacity definition used for SOH calculation.
