Abstract

The invention is suitable for the technical field of new energy batteries, and provides a maintenance tool and a maintenance method. The maintenance tool and the maintenance method are used for disassembling a battery cell connected through an electrode connecting piece in a battery pack, and the maintenance tool comprises a clamping assembly used for clamping the battery pack, a disassembling assembly arranged opposite to the clamping assembly, and a moving assembly; the disassembling assembly comprises a cutter arranged opposite to the electrode connecting piece and a cutter driver used for driving the cutter; and the moving assembly is connected with at least one of the clamping assembly and the cutter driver. The clamping assembly is used for clamping and fixing the battery pack, the moving assembly drives the cutter to move along a preset track, the cutter driver drives the cutter to work, and then the electrode connecting piece connected to an electrode in a welded mode can be accurately disassembled; and when the maintenance tool provided by the embodiment is used for dismounting the electrode connecting piece, the charging and discharging functions of the battery cell are not influenced, and the shape and the size of the electrode are controllable, so that the reuse of the battery cell is not influenced.

Description

technical field [0001] This application relates to the technical field of new energy batteries, in particular to a maintenance tool and a maintenance method. Background technique [0002] New energy technology has developed rapidly in recent years, and in practical applications, new energy technology is inseparable from the support of battery packs. The existing new energy vehicle industry often uses battery packs with multiple lithium battery cells. The cells in the battery pack are often welded through metal connectors (such as aluminum strip connectors, etc.). To achieve electrical and structural connections. [0003] In the production process of the existing battery pack, when the parameters of the battery pack do not meet the requirements due to factors such as poor manufacturing process or poor incoming materials, it is impossible to replace the battery cell without damaging the battery cell, so it often affects the entire battery pack. The battery pack is scrapped o...
