Battery Enclosure Thermal Runaway Equipment

Compliance

UL 2596


The Battery Enclosure Thermal Runaway Equipment is designed to evaluate the battery enclosure material performance in a simulated battery thermal runaway. It enables testing of the material with a sheet material instead of an entire battery assembly which can reduce development cost and time.

The UL 2596 Test Equipment consists of

  • Test chamber, made of structural steel, with an internal dimension of 100mm x 100mm x 89mm.

  • The top side of the chamber is open and the test sample is secured onto the open side during the test.

  • The midpoint of one side of the chamber is using a vent orifice to release pressure generated during the test.

  • A Type K 24AWG insulated thermocouple is used to measure the internal temperature of the test chamber.

  • A Type K 24AWG insulated thermocouple is used to measure the external temperature of the test sample.

  • A pressure transducer is used to measure the internal pressure of the test chamber.

  • Thermal runaway trigger device, heating up the initialing cells at the rate of 4~7 °C.

  • A PID temperature controller controls the heating of the film heater, the range of 0 to 1,000°C, with an accuracy of 0.1°C.

  • Two Type K 24AWG insulated thermocouples are used to measure the surface temperature of the initialing cells individually.

  • The temperature of the initialing cells are monitored during the test.

  • Data acquisition system, collects the temperature, pressure, and time at a rate of 10 samples per second.

  • Window based operation software, with the functions:

    - Records the internal temperature of the test chamber.

    - Records the external temperature of the test specimen.

    - Records the surface temperature of the initialing cells.

    - Records the pressure of the test chamber.

    - Control the heating of flexible film heaters at a specific rate.

    - Records the time, and generates the time-synchronized plots of temperature & pressure.

    - Generates the maximum temperature & pressure.

    - Report export and management.
