Online distributed storage battery pack monitoring device

Abstract

The invention provides an online distributed storage battery pack monitoring device which comprises a battery gathering module, a dynamic environment monitoring center, battery modules and a Hall sensor. The input end of the Hall sensor is connected to a charging and discharging loop of a storage battery pack in series, and the output end of the is connected to a current collecting input end of the battery gathering module; the input ends of the battery modules are connected to the positive and negative ends of tested batteries of the storage battery pack correspondingly, and the output ends of the battery modules are connected to the input end of the battery gathering module via a communication and control bus; and a voltage collecting input end of the battery gathering module is connected to a terminal voltage detection line of the storage battery pack, and the output end of the battery gathering module is connected to the input end of the dynamic environment monitoring center. The monitoring device can monitor the voltage, internal resistance and temperature of tested batteries in an integrated way, and the problem that hidden fault troubles of the lead acid batteries cannot bediscovered and solved timely is solved via an unmanned and onsite networking manner.

Description

technical field [0001] The invention relates to an online monitoring device for a lead-acid storage battery group. Background technique [0002] Backup power supply includes power backup power supply and communication backup power supply, which are currently widely used in various industries, including communication, electric power, finance, medical care, petrochemical, education, transportation, and even various industries of basic necessities of life. The main purpose of the backup power supply is to prevent serious accidents such as abnormal shutdown of important equipment, loss of data, loss of control of power machinery and equipment due to temporary interruption of mains power, resulting in huge economic losses. Therefore, how to maintain the backup power system, especially the backup lead-acid battery pack, has become one of the important tasks of the industry's backup power management department. [0003] However, the lead-acid battery packs where the backup power s...
