Relevant Standard Testing Requirements
1.1 The test object is a battery pack or system.
1.2 Apply pressure according to the following conditions.
1.2.1 Squeezing plate form: A semi-cylindrical plate with a radius of 75mm. The length of the semi-cylinder is greater than the height of the test object, but does not exceed 1m. (It should be noted that you may have a typing error here, "but not exceed 1mm" is not reasonable, I assume you mean 1m. If it is not the case, please correct it.)
1.2.2 Squeezing direction: The X and Y directions (The vehicle driving direction is the X-axis, and the other horizontal direction perpendicular to the driving direction is the Y-axis).
1.2.3 Squeezing degree: Stop squeezing when the squeezing force reaches 200kN or the squeezing deformation amount reaches 30% of the overall size in the squeezing direction.
1.2.4 Maintain for 10 minutes and observe for 1 hour.
1.3 Requirements: There should be no phenomena such as fire and explosion in the battery pack or system.
