The present invention provides a safety auxiliary device for battery pack air tightness detection, comprising a main body rod, first clamping blocks sleeved on both ends of the main body rod respectively, and a plurality of second clamping blocks disposed on both sides of the main body rod , two first clamping blocks slide along the main body rod to clamp the battery pack in the length direction, a plurality of second clamping blocks are arranged along the length direction of the main body rod and fit with the top surface of the battery pack, the first The two clamping blocks are slidably connected with the side surface of the main body rod and slide along the length direction of the main body rod. The two first clamping blocks provided in the present invention clamp both ends of the battery pack in the length direction, and the second clamping blocks are in contact with the top surface of the battery pack to clamp the battery pack in the height direction. The positions of the first clamping block and the second clamping block are slidably adjusted to achieve compatibility of different battery packs, thereby preventing the battery pack from bulging, avoiding the performance degradation of the battery pack, and improving the safety during the air tightness test.
Description
technical field [0001] The invention relates to the technical field of battery pack detection, in particular to a safety auxiliary device for battery pack air tightness detection. Background technique [0002] With the continuous development of society, the utilization rate of automobiles is getting higher and higher, and traditional automobiles are polluting. Gradually, the development of new energy vehicles is getting faster and faster, and battery packs are the main source of power for new energy vehicles. The battery pack is tested for air tightness to prevent the battery pack from short-circuiting due to air leakage and water seepage. [0003] At present, there are three steps in the air tightness detection process of the battery pack: pre-pressure, voltage regulation, and pressure relief. However, during the air-tightness test, the battery pack will bulge, causing the voltage inside the battery pack to become unstable, resulting in a gradual decline in the performance...
