Dual-state Thermal Parameter Tester
Developed based on non-contact infrared thermal imaging and three-dimensional heat-transfer model inversion analysis, the TCA 2SC-080-E is a thermal parameter analysis instrument designed for heterogeneous core–shell structured samples. It enables non-destructive testing of thermal conductivity and internal thermal resistance for hard-case lithium-ion battery cells without disassembly.

Features
No destructive sample preparation required; enables accurate in-situ measurement of multi-directional thermal conductivity of battery samples.
Supports a wide range of sample sizes with low requirements for surface flatness.
Test parameters are automatically configured based on sample information and dynamically adjusted during the test process.
Suitable for homogeneous or heterogeneous samples with different dimensions, surface hardness, roughness, and porosity.
Based on a three-dimensional heat-transfer model for testing and inversion analysis, enabling simultaneous measurement of in-plane thermal conductivity, through-thickness thermal conductivity, and overall effective thermal conductivity of the cell core.
Supports external battery charge–discharge equipment to realistically simulate heat generation under charging and discharging conditions.
Supports adjustable cold-plate temperature and flow rate to simulate different heat dissipation conditions.
Uniform temperature control using six-sided cold plates combined with high-precision oil bath temperature control, with adjustable ambient temperature.
Simple operation with fully automated test initiation and execution.
