Abstract

The invention relates to a battery pack sealing detection system. The battery pack sealing detection system comprises a testing connection pipe, a liquid-storage container and a transparent tube; a compressed air inlet is arranged in the liquid-storage container; the testing connection pipe is communicated with the liquid-storage container; and the transparent tube is vertically arranged and is communicated with the liquid-storage container. Preferably, the liquid-storage container is a liquid-containing tank, the transparent tube is a glass tube, and the transparent tube is provided with a first graduation and a second graduation which are arranged at intervals from top to bottom. The battery pack sealing detection system further comprises a control valve; the control valve is mounted on the compressed air inlet; and a liquid-compensating port is further arranged on the liquid-storage container. The battery pack sealing detection system further comprises a bracket; the bracket is vertically arranged; and the transparent tube is fixedly arranged on the bracket. The battery pack sealing detection system further comprises a base, and the liquid-storage container is mounted on the base. The battery pack sealing detection system provided by the invention is unique in design and ingenious in conception, and therefore, the battery pack sealing detection system can be used for the air-tightness test with larger volume; and the detection method is simple, the detection performance is reliable and direct-viewing, and the detection equipment is low in cost, thus the battery pack sealing detection system is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to the technical field of detection systems, in particular to the technical field of seal detection systems, and specifically refers to a battery pack seal detection system, which can be used to detect whether the battery pack is leaking after the battery pack for electric vehicles is assembled. Background technique [0002] At present, new energy vehicles are becoming a development hotspot, especially the development of pure electric vehicles has become the focus of new energy vehicle development, and major automobile companies are investing huge sums of money in research and development. The most critical part of an electric vehicle is the battery. For vehicle manufacturers, in addition to controlling the quality of the battery, special attention must be paid to the quality of the battery pack. The sealing performance of the battery pack is related to the safety of the electric vehicle and the life of the battery pack. Special a...
