A high-vibration-resistant deep-cycle battery

Abstract

The invention provides a deep cycle battery with high vibration resistance, which includes a battery body, an electrode group, an electrode fixing mechanism, a limiting plate and a buffer mechanism. The inside of the battery body is provided with an electrode group, and the top of the electrode group is connected to There is an electrode fixing mechanism, and the electrode fixing mechanism is used to limit the position of the pole group. There is a buffer mechanism between them. The advantage of the present invention is that: the limiting plate is combined with the electrode fixing mechanism, so that the electrode fixing mechanism and the pole group are more fit, and at the same time, the downward extrusion of the pole group makes the bottom of the pole group more fit to the buffer mechanism, and the volume of the buffer mechanism It can be changed, and the pole group is limited from the bottom and top of the pole group at the same time. During the use of the battery, the vibration resistance of the electrode group inside the battery body is better, so that the service life of the battery body is longer.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a high-vibration-resistant deep-cycle battery. Background technique [0002] At present, many battery manufacturers are producing power batteries for trucks, engineering vehicles, and ships. The vibration performance requirements meet the 5G8h vibration or 5G48h (customer standard) vibration of B-type batteries in the GB / T5008.1-2013 standard. The specific requirements are as follows: [0003] After the battery is fully charged, the open circuit voltage is collected during the vibration process. After the vibration is completed, the battery is discharged at 800A for 30s in an environment of 25±5°C without charging, and the terminal voltage of the battery is recorded. The terminal voltage is ≥ 7.2V to determine that it is qualified. [0004] At present, power batteries for trucks, engineering vehicles, and ships on the market have relatively poor vibration resistance consistency...

AI Technical Summary

Problems solved by technology

[0004] At present, power batteries for trucks, engineering vehicles, and ships on the market have poor consistency in vibration resistance. According to the above test method, the vibration resistance performance is difficult to reach 8h, and some batteries fail after 10-20min of vibration.
