Abstract

The present invention discloses a device for testing accumulator on line which comprises of monomer measuring module, CPU control module and power supply module. CPU control module controls monomer measuring module and power supply module and transfers measuring result and power supply module information to CPU control module to store and process, wherein, a constant current module parallel connected to power supply module to make the current output from power supply module and constant current module is invariableness. The structure of present invention saves electricity without adding heating load in discharging process, realizes grouping on line constant current discharging and measuring capacity of accumulator efficiently and safely.

Description

Technical field [0001] The invention relates to a storage battery testing device, in particular to a testing device used for testing the battery capacity of a storage battery pack in a basic power supply of a communication machine room (on-line) in a working state. Background technique [0002] The power supply is an essential part of the communication network, and the quality of the power supply is directly related to the smooth flow of the entire communication network. In communication technology, transmission, sending, receiving, calling and other equipment use DC-48V as the power supply of communication equipment. In order to realize uninterrupted and stable operation of communication equipment, all communication equipment power systems are equipped with battery packs . The working principle of the battery is to store and release electrical energy through a chemical reaction: Pb (negative electrode) + PbO2 (positive electrode) + 2H2SO4 = 2PbSO4 + 2H2O (discharge reactio...
