Abstract

The invention relates to the field of lithium battery repair, in particular to lithium battery detection and repair equipment and a repair method thereof.The lithium battery detection and repair equipment comprises a U-shaped frame, a limiting assembly is fixed to the top of the U-shaped frame, pressure measuring polar plates are arranged above and below the limiting assembly, the detection faces of the two pressure measuring polar plates are opposite, and a vertical plate is fixed to the side edge of the U-shaped frame; a closing mechanism is installed between the vertical plate and the limiting assembly, the voltage measuring polar plate is connected with the closing mechanism, a digital voltmeter is installed on the surface of the vertical plate, and the two sets of outer electrode pieces are connected with the positive electrode connecting end and the negative electrode connecting end of the digital voltmeter respectively. The movable electrode plate is pressed by the plane of the battery body or the battery cap to form different degrees of retraction, so that the movable electrode plate is in contact with different inner electrode plates, the position of the battery body does not need to be replaced, the electrode end of the battery body can directly and correctly correspond to the electrode end of the digital voltmeter, and the detection and repair efficiency of the lithium battery is improved.

Description

technical field [0001] The invention relates to the field of lithium battery repair, in particular to a lithium battery detection and repair device and a repair method thereof. Background technique [0002] Lithium battery is a relatively common storage battery. As the concept of environmental protection is gradually implemented in daily life, the use of new energy is becoming more and more extensive. Electric energy is a relatively large proportion of new energy. The use of electric energy depends on the storage of batteries. Its excellent power storage performance is widely used. [0003] There are many types of lithium batteries, and the adaptability will be adjusted according to different uses. The lithium battery pack is a combination of multiple single batteries. This structure not only realizes large-capacity energy storage, but also can increase or decrease The size of the battery pack can be used in a wide range. [0004] After a long-term use of lithium battery p...
