Thermal Abuse Test Chamber

The Thermal Abuse Test Chamber LEGTA-180 heats a single cell or a battery module at a controlled ramp to a set temperature and holds it while the specimen is observed. It is built for the heating tests of IEC 62133-2017, UL 1642 and GB 31241-2014. The chamber ramps from room temperature to 150 °C at a linear 5 °C/min, with ±0.5 °C control accuracy and ±2.0 °C deviation at no load.

How it works

The specimen is placed in the 600 × 500 × 600 mm working cabinet, wired through 50 mm terminal holes in the side walls, and the door is closed on an explosion-proof lock and chain. The 7 in PLC touch panel runs the profile. In the standard sequence, a charged lithium-ion cell is heated to 130 °C ± 2 °C at 5 °C/min, held for 30 minutes and then observed for 1 hour; nickel metal hydride cells are heated to 85 °C ± 2 °C and held for 2 hours. Test data are exported by USB.

The inner chamber is mirror-finish SUS304 stainless steel inside a 1.5 mm SECC steel shell with powder coating, insulated with high-density glass wool and high-temperature silicone seals. A 390 × 360 mm window of 20 mm explosion-proof glass with a mesh guard allows observation. An explosion-proof pressure relief device, smoke exhaust, explosion-proof lighting, electronic door lock and safety stop switch contain and vent an event. The cabinet is 940 × 780 × 1620 mm overall on casters and runs on 220 V, 50 Hz, 4.0 kW.

Main Technical Parameters

The heating test of battery thermal abuse test chamber shall be carried out as follows

1. Relevant standard test requirements

• Single battery safety test
• The heating test is carried out as follows:
• The single battery is charged according to the method of 6.1.3
• Put the single battery into the temperature chamber.For lithium-ion batteries, the temperature chamber is increased from room temperature to 130 ° C ± 2 ° C at a rate of 5 ° C / min, and the heating is stopped after maintaining the temperature for 30 minutes.
• For nickel metal hydride batteries, the temperature chamber is raised from room temperature to 85 ° C ± 2 ° C at a rate of 5 ° C / min, and the heating is stopped after maintaining this temperature for 2h.
• Observe for 1h.

2.Battery module safety test

• The battery module battery shall be charged according to the method in 6.1.4.
• For lithium-ion batteries, the temperature chamber is raised from room temperature to 130 ° C ± 2 ° C at a rate of 5 ° C / min, and the heating is stopped after maintaining this temperature for 30 minutes.
• For nickel metal hydride batteries, the temperature chamber is raised to 85 ° C ± 2 ° C at room temperature at a rate of 5 ° C / min, and the heating is stopped after maintaining this temperature for 2h.
• Observe for 1h.
