Problems solved by technology

[0003] The existing drop tests for battery packs on the market are all free-fall drop tests on the battery pack alone, or flip tests on the battery pack alone. The test strength is insufficient, and it is impossible to accurately simulate the rollover of the battery pack driven by the vehicle or the battery rack. Damage to the battery pack, so the safety of the battery pack cannot be accurately verified

Abstract

The invention relates to the technical field of battery pack testing, in particular to a battery pack drop test method and a battery pack drop test device. The invention provides a battery pack drop test method. The method comprises the following steps: fixing a battery pack on a drop table; and the battery pack is released, so that the battery pack falls down along with the falling table, and the battery pack falls onto the ground after being turned over along with the falling table. The battery pack drop test method can accurately simulate the damage to the battery pack when the vehicle or the battery rack actually rolls over, so that the safety of the battery pack is accurately verified, and the battery pack drop test method is simple and convenient to operate. According to the battery pack drop test device provided by the invention, the drop test is carried out on the battery pack by applying the battery pack drop test method, the safety of the battery pack is accurately verified, the structure is simple, the cost is low, and the battery pack drop test device can be conveniently processed and produced.

Description

technical field [0001] The invention relates to the technical field of battery pack testing, in particular to a battery pack drop test method and a battery pack drop test device. Background technique [0002] The battery pack can supply power to electronic devices. The safety of the battery pack seriously affects the service life of the electronic device. For example, the battery pack in the vehicle or the battery pack placed on the battery rack, when the vehicle or the battery rack drives the battery pack to roll over, Poorly safe battery packs or substandard battery packs are prone to short circuit, fire or even explosion. Therefore, for the battery pack, the battery pack drop test can detect the drop resistance of the battery pack and verify the safety performance of the battery pack. [0003] The existing battery pack drop test on the market is to perform a free-fall drop test on the battery pack alone, or perform a flip test on the battery pack alone. The test strength...
