Dual-state Thermal Parameter Tester

Non-destructive, in-situ accurate measurement of multi-dimensional thermal conductivity for battery samples.

Capable of testing a wide range of sample sizes with minimal surface flatness requirements.

Automatic setting of experimental parameters based on sample information, with adjustments made during the test process.

Suitable for homogeneous or heterogeneous samples of various specifications, surface hardness, roughness, and porosity.

Utilizes a 3D heat transfer model for testing and inversion analysis, measuring parameters such as core transverse thermal conductivity, core longitudinal thermal conductivity, and overall equivalent thermal conductivity.

Supports external battery charging and discharging equipment to realistically simulate thermal conditions during these processes.

Adjustable sample cold plate temperature and flow rate to simulate different heat dissipation conditions.

Uniform temperature across six-sided cold plates, high-precision oil bath temperature control, and adjustable ambient temperature.

Simple instrument operation with fully automated test initiation and execution.
