Product Introduction
The battery cell pressure vessel device is mainly used to meet the needs ofThe UL 9540A standard specifies the requirement for thermal runaway testing of battery cells, which can meet the functions of placing commercially available batteries, vacuuming internal chambers, nitrogen charging, as well as measuring parameters such as pressure, temperature, and oxygen concentration. In addition, it reserves interfaces for thin film heating and overshoot circuits.

characteristic
1. The sealed cabin adoptsMade of 304 stainless steel material, with an internal diameter of 480mm, a length of 500mm, and a testing space volume of approximately 90L.
2. Maximum pressure resistance of the cabin10Mpa, with a constant withstand pressure of not less than 3MPa, and a safety valve with an engineering pressure of 6.4Mpa is installed on the cabin.
3. Multiple flange connection plates are reserved in the cabin, and dedicated card sleeve joints are used on the connection plates for temperature, voltage, heating, overshoot and other circuit connections.And reserve a nitrogen filling interface，Used to connect external nitrogen to achieve cabin oxygen concentration<1% environment configuration.
4. The battery cell installation port adopts a movable door opening and closing method, and is equipped with locking screws to ensure the sealing of the cabin. It is equipped with a movable metal sample bracket inside, with a structural inlet for stable placement.
5. Equipped with Thomas sampling pump, the exhaust speed can be manually adjusted to achieve the interior of the cabin-90KPa vacuum pumping capacity.
6. Equipped with pressure sensors, pressure monitoring range-0.1MPa——0.5MPa(Can be customized according to actual usage conditions)
7. Equipment reservation13 temperature acquisition channels，Temperature display accuracy0.1℃
8. Equipment reservationTwo voltage acquisition signals are used to test the real-time voltage changes of the battery cells.
9. All pipeline and sensor interfaces are reserved with manual ball valves and solenoid valves，Can protect sensors and block gas leaks inside the cabin；
10. Reserve one manual sampling interfaceEquipped with a mode filter and filtering accuracy0.μm.
