Abstract

The invention provides a battery detection device, equipment and structure, and relates to the field of battery. The battery detection device comprises a gas inlet pipe, a gas collection unit, an airpressure detection unit and a three-way valve, three ports of the three-way valve are communicated with the gas inlet pipe, the gas collection unit and the gas pressure detection unit respectively, the gas collection unit comprises a connection part connected with the three-way valve and a gas collection part connected to the connection part, and the connection part only allows gas being input only in the direction from the three-way valve to the gas collection part. The battery detection device can collect produced gas via the gas collection unit to determine the gas production amount; the pressure of produced gas can be detected by the air pressure detection unit; and thus, a battery can be optimized in design in a more convenient way.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery testing device, battery testing equipment and a battery testing structure. Background technique [0002] With the rapid development of new energy vehicles, the importance of power battery packs has become increasingly prominent. Among them, the battery cell design of the power battery pack needs to consider the positive and negative electrode materials, electrolyte, etc., and avoid the battery from being aggravated by abnormalities or excessive gas production during the formation process, which will cause the battery pack to fail to assemble smoothly. Therefore, it is necessary to reasonably analyze the cause of gas production by detecting the gas production of the battery and select the appropriate positive and negative electrode materials, electrolyte and the rationality of the entire processing technology arrangement of the battery to optimize the battery design an...
