Isothermal Calorimeter for Batteries
The Isothermal Calorimeter for Batteries is designed to measure the heat generated by batteries during charging and discharging under controlled temperature conditions. By combining power compensation and heat-flow measurement methods, the instrument supports thermal characterization of batteries of different sizes, from cylindrical cells to pouch and prismatic cells.
The system features an oil bath with a temperature control range of -40°C to 100°C, integrated battery charge-discharge control, and real-time recording of voltage, current, and temperature. It also supports battery heat capacity measurement and instrument calibration under different test conditions. The calorimeter is suitable for battery research, thermal management development, and performance evaluation in battery laboratories.
