Technology

Q&A

【Q】What is the working principle of a battery adiabatic calorimeter?

【A】The BAC series employs adiabatic tracking technology to monitor cell temperature in real time while dynamically adjusting the chamber environment temperature, driving the temperature differential between cell and chamber toward zero. This effectively eliminates heat exchange, ensuring that all observed temperature changes originate solely from the cell's own heat generation or absorption. The system can therefore induce and record the complete thermal runaway process, yielding accurate characterization of key thermal runaway parameters.

【Q】What tests can a battery adiabatic calorimeter perform?

【A】The BAC series supports thermal abuse testing, electrical abuse testing, mechanical abuse testing, specific heat capacity testing, visual monitoring, gas evolution analysis, and charge/discharge calorimetry. These capabilities cover the full spectrum of battery thermal safety evaluation, from abuse triggering to gas analysis and heat generation measurement.

【Q】What key parameters does adiabatic calorimetry provide?

【A】Thermal runaway characteristic temperatures (T₁, T₂, T₃), adiabatic temperature rise, specific heat capacity, charge/discharge heat-generation power and total heat generation, pressure-rise rate, and maximum gas-generation pressure.

【Q】How is adiabatic calorimetry used in battery thermal safety evaluation?

【A】The system enables thermal runaway testing of large-format single cells or small modules under adiabatic conditions to obtain thermal stability characteristic parameters. It also supports cell-level gas-evolution assessment within the UL 9540A standard framework, providing gas volume and generation-rate data to inform module and pack-level venting and burst-protection design. Gas sampling and analysis further enable evaluation of cell-level gas hazards.

【Q】How does adiabatic calorimetry support battery thermal management?

【A】The system measures heat generation, heat-generation rate, and temperature-dependent specific heat capacity across a wide temperature range, including low-temperature conditions. These data provide the quantitative basis for battery thermal management system design and validation.

【Q】Can adiabatic calorimetry be used for battery material testing?

【A】The system enables thermal stability testing of electrolytes, cathode and anode materials, and separators to obtain thermal decomposition characteristic parameters, supporting the improvement of cell and system safety design.
