1, the test purposes are different: generally, the aluminum case does not explode under the pressure of 1.2Mpa, and the expansion of the battery case is observed when the aluminum case is impacted by high-pressure gas to evaluate the pressure resistance of the aluminum case; The bursting pressure test means that the aluminum case explodes under the pressure of 1-3.5Mpa, that is, the aluminum case is impacted by high-pressure gas, and the strength of the aluminum case is evaluated by observing the damage of the battery case.

2, the test results are different: the withstand voltage test can test whether the battery case will be deformed after being pressed for a long time; The bursting test can test whether the battery case will be damaged under instantaneous pressure.
