Battery heavy impact tester is a special device used to test the safety performance of batteries. It is mainly used to simulate the case of a battery being hit by a heavy object in an unexpected situation to evaluate the safety performance of the battery. Battery heavy impact testing machine is usually composed of a drop hammer mechanism and a test bench.

The drop hammer mechanism is the core component of the battery heavy impact testing machine, which can control the height and speed of the drop hammer to simulate different impact forces. The experimenter can adjust the height and speed of the drop hammer to simulate different conditions according to the specific test requirements. Under the control of the drop hammer mechanism, the drop hammer will impact the battery on the test bench with a certain speed and force, simulating the case of the battery being hit by a heavy object in an unexpected situation.

The testing bench is another essential part of the battery impact test equipment, which is used for fixing the sample to be tested. The battery which will be tested is placed on the test bench, and the battery’s safety performance is evaluated by observing and recording the reaction of the battery during the impact. The test bench usually has a height adjustable function to accommodate different specifications and models of battery testing.

In the test, the battery heavy impact tester can record the changes of the battery's temperature, voltage, current and other parameters to evaluate the reaction of the sample in the impact process. Meanwhile, the machine can also make judgement of the specimen’s safety performance after the impact test via the observation of the changes of the battery surface, checking if the battery shell
is broken, and if the battery is leaked inside.

The battery heavy impact test machine is greatly utilizing in the field of battery manufacturing and research and development, especially in the mobile electronic devices like electric vehicles, smart phones, laptops and so on. For these devices, the battery is one of the core components, and the safety performance is very significant. By taking advantage of the battery heavy impact test equipment, it can help better understand the safety performance of the battery, improve the safety and reliability of the battery.
