Description
This Thermal Abuse Case Stress Test Chamber can be used for module case stress at high ambient temperatures as well as thermal abuse and thermal testing. After the battery (pack) is charged, test it at ambient temperature of 70±2°C for 7h, then shift it out from the oven, cool to room temperature, and the battery case required free from physical deformation that causes the internal components to be exposed.
Place each fully charged cell in a natural convection or forced air oven. The oven is raised to an average heating rate of 5 ± 2 ° C to 130 ± 2 ° C. The battery is maintained at this temperature for 30min, the battery does not explode, no fire is qualified.
