Analysis of online diagnosis and repair technology of lead acid battery faults

Abstract

Lead-acid battery, as a basic component of DC power supply equipment in power communication system, is also known as maintenance-free battery. It is believed that it does not need maintenance treatment in the initial stage of application research. However, as an electrochemical product, it has relatively high requirements for both use environment and operation. It is the main problem discussed in electric power industry at present. In this paper, on the basis of understanding the research status of online fault diagnosis technology of lead-acid battery, according to the basic principle of lead-acid battery and online detection system, discharge treatment of two groups of tested single battery load, calculate and analyze the battery resistance value. The final experimental results show that this method can solve the safety hazard of the whole battery line discharge, control the equipment cost, and ensure the fault location is more accurate and effective.
