Storage battery internal resistance online real-time monitoring system

Abstract

The invention discloses a storage battery internal resistance online real-time monitoring system, and relates to the technical field of storage battery monitoring. The storage battery internal resistance online real-time monitoring system comprises a storage battery internal resistance data acquisition terminal, a data concentrator and a server management platform, wherein the storage battery internal resistance data acquisition terminal measures the internal resistance of a storage battery through hardware, carries out MCU data processing on the internal resistance, and then communicates withthe data concentrator through a 485 bus to exchange data with the data concentrator; the data concentrator uploads the data acquired by the multiple paths of storage battery internal resistance dataacquisition terminals to a server through a network switch and a router, and monitors a running state of a storage battery and the data uploaded by the data concentrator online through using a management computer and exchanges data with the server management platform; and the server management platform queries the internal resistance measurement data from a data management center and displays theinternal resistance measurement data. The storage battery internal resistance online real-time monitoring system can be effectively used for measuring the internal resistance of the lead-acid storagebattery, the measurement result is stable, reliable and effective, and a user can monitor and know the health state of the storage battery in real time through multiple platforms.

Description

technical field [0001] The invention relates to the technical field of battery monitoring, in particular to an online real-time monitoring system for battery internal resistance. Background technique [0002] In modern society, it is difficult to imagine the economic and socio-political damage to the government when the power grid is paralyzed. This has UPS (Uninterruptible Power System / Uninterruptible Power Supply), that is, uninterruptible power supply. Now uninterruptible power supply is widely used, such as server room, network equipment, data storage equipment, hospital, national defense, substation, power station, nuclear power station, etc. . Sophisticated network equipment and communication equipment do not allow power interruption, so the reliability of the storage battery is related to the safety and stability of the entire system. Battery failure or insufficient capacity may cause major accidents. Therefore, on-line detection and monitoring of storage battery h...
