Problems solved by technology

Therefore, it is particularly important to test the internal resistance of the battery before using it. However, the traditional battery internal resistance tester still has various deficiencies during use, so it cannot meet the needs of practical applications. For example: Chinese patent authorization The utility model patent with the announcement number CN201903589U and the authorized announcement date on July 20, 2011 discloses a tool for detecting the internal resistance of lithium-ion batteries. The purpose is to improve the detection speed and work efficiency. The technical solution adopted for this purpose is: tool The positive and negative metal sheets corresponding to the positions of the positive and negative poles of the battery to be tested are arranged in the housing, and the positive and negative metal sheets are connected to the voltage internal resistance meter through wires
When in use, the internal resistance reading of the battery can be displayed by placing the battery to be tested directly in the tooling case. Although the detection speed and work efficiency are improved, the structure of this device is too simple, resulting in poor stability and poor measurement accuracy. lower

Abstract

The invention discloses a cell internal resistance detector which comprises a base, and is characterized in that the base is equipped with a probe fixing seat; the probe fixing seat comprises a left probe fixing seat and a right probe fixing seat; the probes in contact with electrodes of the detected cell are mounted on the left probe fixing seat and the right probe fixing seat oppositely; and a detected cell fixing seat is mounted on the base and located between the left probe fixing seat and the right probe fixing seat. The cell internal resistance detector is convenient to operate, and the measuring accuracy is high.

Description

technical field [0001] The invention relates to a detector, in particular to a battery internal resistance detector. Background technique [0002] The internal resistance of the battery is an important parameter of the battery, which not only reflects the current nuclear power state of the battery, but also reflects the degree of deterioration of the battery. Therefore, it is particularly important to test the internal resistance of the battery before using it. However, the traditional battery internal resistance tester still has various deficiencies during use, so it cannot meet the needs of practical applications. For example: Chinese patent authorization The utility model patent with the announcement number CN201903589U and the authorized announcement date on July 20, 2011 discloses a tool for detecting the internal resistance of lithium-ion batteries. The purpose is to improve the detection speed and work efficiency. The technical solution adopted for this purpose is: to...
