Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a battery module sampling structure. Background Art

[0002] The battery module is the core component of the battery system in electric vehicles. The temperature of the battery cells in the battery module is the core parameter of the battery system. Therefore, the temperature sampling of the battery cell temperature directly affects the performance and safety of electric vehicles. When the electric vehicle is running or charging, the battery cell will generate a lot of heat, which will increase the temperature of the battery module. Excessive temperature will cause thermal runaway of the battery pack. When the battery works under low temperature conditions, it will cause internal damage to the battery cell and shorten the service life of the battery pack. Therefore, it is necessary to accurately sample the temperature of the battery cell;

[0003] In the prior art, temperature sampling is usually performed by laser welding a temperature sampling piece and a bus bar. The reliability of the connection between the temperature sampling piece and the battery cell is poor, resulting in an inability to accurately sample the temperature of the battery cell.

[0004] The existing patent (Announcement No.: CN212585868U) discloses that the cover plate is connected to the clamping column, and the cover plate is pressed on the temperature sampling piece. One end of the temperature sampling piece is provided with a bending part. When the cover plate is pressed on the temperature sampling piece, the bending part abuts against the battery cell and produces elastic deformation, thereby closely abutting against the battery cell. Through the above arrangement, the reliability of the connection between the temperature sampling piece and the battery cell is guaranteed, thereby achieving accurate sampling of the battery cell temperature.

[0005] However, the above technical solution still has certain defects. First, the device uses various fixing clips to fix the abutment, which is cumbersome to install and has low fixing strength. It may become loose and fall when the device vibrates, resulting in poor contact and affecting the sampling accuracy. In addition, there is no protective structure on the upper end of the battery of the device, and the safety of the battery is relatively low. For this reason, a battery module sampling structure is proposed. Utility Model Content
