Features
Accurately measures effective thermal conductivity of battery samples without sample destruction.
Compatible with a broad range of sizes and low surface flatness requirements, covering homogeneous and heterogeneous samples of varying specifications, hardness, roughness, and porosity.
Automatically compensates for system heat losses including surface and fixture dissipation, ensuring accurate and reliable results.
Supports external battery charge and discharge equipment to simulate actual heat generation during cycling.
Six-sided cold plate temperature uniformity with high-precision oil bath control. Supports independent cold plate and ambient temperature settings to simulate diverse heat generation and dissipation conditions.
Dynamic test progress display with color maps simultaneously presenting measured data, model predictions, and error evaluation for rapid result validation.
