Lithium battery protection plate for preventing positive and negative electrodes from being in contact with liquid

Abstract

The invention discloses a lithium battery protection plate for preventing positive and negative electrodes from being in contact liquid, and relates to the technical field of lithium battery protection plates. The protection plate comprises a protection plate body, a positive electrode connection point and a negative electrode connection point, the positive electrode connection point and the negative electrode connection point are arranged at the top of the protection plate body, and a waterproof box is fixed to the top of the protection plate body. Through mutual cooperation of the waterproof box, a waterproof quick connection mechanism and a sealing cover plate, the device can provide protection for the lithium battery protection plate conveniently, short circuit caused after positive and negative electrodes of the lithium battery protection plate make contact with liquid is avoided, meanwhile, the device can be connected with an external wire conveniently, the lithium battery protection plate can be installed and overhauled conveniently, and the device is convenient to use; and through mutual cooperation of the waterproof box, the sealing cover plate and a drying agent, the situation that the lithium battery protection plate is located in a humid environment for a long time, and further aerugo rust is generated on the lithium battery protection plate is avoided, and the lithium battery protection plate is prevented from being damaged.

Description

technical field [0001] The invention belongs to the technical field of lithium battery protection plates, in particular to a lithium battery protection plate that prevents positive and negative electrodes from contacting liquid. Background technique [0002] The lithium battery protection board is mainly an integrated circuit board that protects the lithium battery. When the lithium battery is fully charged, it can ensure that the voltage difference between the individual batteries is less than the set value, and realizes the equal charging of each individual battery in the battery pack. Effectively improves the charging effect under the series charging method; simultaneously detects the overvoltage, undervoltage, overcurrent, short circuit, and overtemperature status of each single battery in the battery pack, protects and prolongs the service life of the battery; undervoltage protection enables each When a single battery is discharged and used, the battery is prevented fro...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a lithium battery protection plate that prevents the positive and negative electrodes from contacting liquid, so as to solve the existing problems: most of the positive and negative electrodes of the existing lithium battery protection plate are exposed, and the positive and negative electrodes are easily exposed to the liquid. A short circuit occurs, causing damage to the lithium battery protection board, causing the lithium battery to fail to charge and discharge
