Lithium-ion battery pack cycling dataset with CC-CV charging and WLTP/constant discharge profiles

This work presents a database of a Lithium-ion battery pack cycling test generated from a custom testbench that simulates dynamic driving conditions based on the WLTP cycle.

The current profiles are derived from speed–time data using MATLAB/Simulink and a Tesla Model 3 vehicle model.

The dataset includes the time series of cell voltages, currents, surface temperatures, and pack-level resistance across up to 36 cells arranged in three parallel branches.

Data is recorded under controlled thermal conditions and stored in an efficient PARQUET format.

The system uses a CAN bus architecture and commercial automotive BMS units to replicate in-vehicle communication constraints, enhancing the dataset’s relevance for real-world battery management system development and validation.
