Abstract
The invention provides a clamping tool for lithium ion battery testing. The clamping tool includes a first vertical plate, a second vertical plate and a fastening piece, the first vertical plate and the second vertical plate are oppositely arranged in parallel, a lithium ion battery to be tested is placed between the first vertical plate and the second vertical plate, the two opposite side surfaces of the lithium ion battery to be tested are respectively in contact with the inner side surfaces of the first vertical plate and the second vertical plate; when the lithium ion battery to be testedis placed between the first vertical plate and the second vertical plate, the first vertical plate, the lithium ion battery to be tested and the second vertical plate are fixedly arranged through thefastening piece. The clamping tool for lithium ion battery testing, the first vertical plate and the second vertical plate are arranged on the two opposite side faces of the lithium ion battery to betested respectively, cycling testing is carried out on the lithium ion battery to be tested, and in the testing process, the internal expansion force of the lithium ion battery cannot be exploded fromthe side surface of the lithium ion battery to be tested, so that the expansion force acts on the battery cover, the pressure is released after breaking through an explosion-proof valve, the explosion of the lithium ion battery to be tested can be prevented, and the safety is high.
Description
technical field [0001] The invention relates to the field of battery testing equipment, in particular to a clamping tool for lithium ion battery testing. Background technique [0002] As a secondary battery with high specific capacity, long cycle life and environmental friendliness, lithium-ion battery is widely used in portable devices and electric vehicles. In recent years, with the rapid development of electric vehicles, higher requirements have been placed on lithium-ion batteries. At present, the internal expansion force of the lithium-ion battery can reach 2000kg during the cycle test, and the lithium-ion battery may explode, posing a safety hazard. Contents of the invention [0003] Based on this, it is necessary to provide a clamping tool for lithium-ion battery testing that will not explode. [0004] A clamping tool for lithium-ion battery testing, including a vertical plate 1, a vertical plate 2 and fasteners, the vertical plate 1 and the vertical plate 2 are r...
