Abstract

The invention discloses a square cell expansion force testing device, which comprises a bottom plate, and a first pressing plate and a second pressing plate which are sequentially arranged above the bottom plate; at least two screw rods which are vertically fixed and sequentially penetrate through the first pressing plate and the second pressing plate are arranged on the bottom plate; a fasteningnut is arranged on each screw rod and is arranged above the second pressing plate; a pressure sensor is arranged between the first pressing plate and the bottom plate and connected with a pressure displayer used for displaying pressure values. A digital display range finder is arranged on the second pressing plate and located at the penetrating position of any screw rod. According to the invention, the randomness of measurement can be effectively reduced, errors caused by human factors can be reduced, adjustment can be timely and flexibly carried out according to the test result of the range finder in terms of distance judgment and measurement, the operation is simple, convenient and rapid, and the repeatability is high.

Description

technical field [0001] The invention relates to the technical field of battery testing, in particular to a device for testing the expansion force of a square battery cell. Background technique [0002] Among the many application fields of lithium-ion batteries, the use of lithium-ion batteries mainly includes two application methods: monomer and module. In the usage mode of a single battery cell, only one battery cell is required for the usage mode of the battery cell; in the usage mode of the module battery, the battery cell needs to be used in the form of a single cell-module battery-module battery. In the use environment of a single cell, the state of the cell itself will directly affect the use environment of the cell; in the use environment of a module battery, the state of the single cell is not only directly output from the It will have an impact on the adjacent cells in the module, and the adjacent cells will have a diffuse effect on the surrounding cells. Therefor...
