What is a Battery Drying Oven?

KOMEG battery drying oven

The battery oven is mainly used to test the adaptability of the battery in high temperature environments. The standard for passing the test is that it does not catch fire or explode. The following are some battery standards that require a drying oven for testing:

  • UL 1642:Lithium Batteries
  • UL 2054:Household and Commercial Batteries
  • IEC 62133:Secondary Cells and Batteries Containing Alkaline or Other Non-Acid Electrolytes –Safety Requirements for Portable Sealed Secondary Cells, and for Batteries Made from Them, for Use in Portable Applications
  • IEC 62660-2:Secondary lithium-ion cells for the propulsion of electric road vehicles – Part 2: Reliability and abuse testing


  1. Aging test: Testing the batteries at high temperature for a long time to accelerate the aging of the batteries and evaluate the stability of the batteries for long-term use.
  2. Performance evaluation: Place the battery at different temperatures to evaluate the battery performance.
  3. Safety test: Test the battery under extreme temperatures to evaluate whether the battery has safety issues, such as thermal runaway or overheating.


Because battery testing can be dangerous, we will add some protection devices to ensure the safety.

  • Explosion-proof window: The stainless steel protective grid on the observation window can prevent glass from splashing.
  • Explosion-proof pressure relief port: When the pressure exceeds the set value, the pressure relief port automatically opens to relieve pressure and protect the equipment.
  • Explosion-proof chain: When an explosion occurs, it gives the door space to open, quickly releasing pressure while protecting personnel safety.
  • Smoke detector: gas detector and warning light, which will quickly alarm and light up the red light when smoke is detected.
  • Fire extinguishing device: The four test areas are equipped with separate sprinkler devices, electric smoke exhaust devices, and carbon dioxide fire extinguishing devices to protect test safety.
