Integrated maintenance instrument for storage battery and method for preventing deterioration of storage battery in storage and transportation period

Abstract

The invention relates to an integrated maintenance instrument for a storage battery and a method for preventing deterioration of the storage battery in a storage and transportation period. The maintenance instrument comprises a central control and computation unit, a data collection / output mode selection unit, a desulfurization / charging mode selection unit, a pulse / charging generation unit and an output unit, wherein the central control and computation unit and the data collection / output mode selection unit are respectively connected with a data collection unit. The central control and computation unit sends out a corresponding command to control the data collection unit or the output unit to work, thereby completing data collection of the storage battery, balanced charging of the storage battery or pulsed desulfurization of the storage battery. By adopting the method, the influence of self-discharge of the battery can be effectively overcome, the deterioration of the battery in the storage and transportation period can be effectively prevented, and the manual intervention is not required in the whole process; through the three-stage combined maintenance way of detection protection, balanced charging and pulsed desulfurization adopted by the integrated maintenance instrument for the storage battery, the deterioration of the battery can be effectively eliminated, the lost battery performances are restored and the battery can be always kept in an optimal state in the storage and transportation period.

Description

technical field [0001] The invention belongs to the field of electronic information technology, and relates to a comprehensive intelligent management device for lead-acid batteries, which collects the main parameters of the batteries and transmits them through the network, and restores the performance of the deteriorated batteries online, and in particular relates to a comprehensive maintenance instrument for battery packs; A method of using the comprehensive maintenance instrument to prevent battery deterioration during storage and transportation. Background technique [0002] Solid valve-regulated sealed lead-acid batteries, which are widely used in communication, electric power, banking, railway and other systems, have outstanding advantages such as light weight, less land occupation, less pollution, and less maintenance. However, after the lead-acid battery is produced, self-discharge will occur during the storage and transportation period. If the battery is not treated ...

AI Technical Summary

Problems solved by technology

However, after the lead-acid battery is produced, self-discharge will occur during the storage and transportation period. If the battery is not treated in time, the battery will be in a state of power loss for a long time, and lead sulfate crystals will be formed and gradually vulcanized. The longer the time, the more serious the vulcanization degree

Due to the difference of batteries, the vulcanization degree of each battery is different. After the battery is put into use, the rectifier starts to charge the battery pack, and the vulcanization speed of the battery will slow down. However, conventional charging cannot restore the vulcanization crystals formed during storage and transportation. The vulcanized flaws formed during the transportation period cannot be eliminated by conventional charging, and the formed lead sulfate crystals are irreversible. The vulcanized flaws formed during the storage and transportation period of the battery already exist or the battery has deteriorated during the storage and transportation period.
