Background
The tightness of the battery pack is an important performance index, so that the airtightness of the battery pack needs to be detected in the production process, and the battery pack is prevented from being short-circuited due to air leakage and water seepage.
At present, the air tightness of the battery pack is mainly detected by a differential pressure method, namely: and inflating the interior of the battery pack, judging whether the internal and external pressure difference of the battery pack changes, if so, indicating that the air tightness of the battery pack is poor, and if not, indicating that the air tightness of the battery pack is good. However, this method causes the internal pressure of the battery pack to be too high, and the upper cover of the battery pack is easily pushed open by the air pressure, so that the sealing performance of the battery pack is easily damaged. In addition, because more parts are arranged in the battery pack, and part of the parts have certain gas accommodating spaces, when the battery pack is inflated to detect the air tightness of the battery pack, the inflation time is increased, and the air tightness detection efficiency is reduced.
