Abstract

The invention discloses a battery pole welding quality detection device and method, and the device comprises: a sealed container which is used for placing a detected battery; a gas mixer which is used for being connected with the detected battery in the sealed container and filling detection gas into the detected battery; and a gas detection device which is connected with the sealed container and is used for detecting the leakage rate of the detected battery after the detected battery is filled with a certain amount of detection gas by the gas mixer. The welding quality of the battery pole is detected in real time under the condition that the battery is not damaged, different battery cavities can be inflated at the same time, multiple cavities can be detected at the same time, the detection accuracy is high, and the efficiency is also high.

Description

technical field [0001] The present application relates to the field of new energy power battery pole welding, in particular to a battery pole welding quality detection device and detection method. Background technique [0002] With the increasing popularity of new energy vehicles, the power battery system is an important way to provide energy sources. In order to meet the high power requirements of the power battery system, a certain number of battery cells need to be loaded in the power battery system, and the positive and negative electrodes of these cells are connected through the connecting piece to meet the requirements of the total power and output voltage. The connecting piece is connected to the pole of the battery cell, and there are requirements such as large overcurrent and small internal resistance. Laser galvanometer welding is mostly used in the industry. The welding area is the position where the connecting piece contacts the battery pole. The quality of weld...
