Multi-condition Battery In-situ Sensing Data

This dataset contains the test data of silicon-based lithium-ion batteries under different working conditions. Among them, time, current, voltage, and discharge capacity (dis_cap) are raw data directly collected by the battery testing equipment, with units of second (s), ampere (A), volt (V), and watt-hour (Wh) respectively. Wavelength 1 and Wavelength 2 (with units of nm) are the wavelength variation signals measured by two implanted Fiber Bragg Grating (FBG) sensors, which can reflect the changes in the internal mechanical and thermal states of the battery. The temperature and force parameters (with units of °C and N, respectively) are obtained through decoupling calculation of the wavelength signals, while the State of Charge (SOC) is calculated from the discharge capacity (dis_cap) using the ampere-hour integration method.
