Abstract

The invention discloses a battery online monitoring system and method. The system comprises a host computer, a battery information integrated management host, a data concentration module and a plurality of data acquisition modules. The data acquisition module is used for acquiring the individual voltage, the, the internal resistance, the charge and discharge current and temperature information ofa battery pack, and adjusting the voltage balance of the battery pack. The battery information integrated management host is electrically connected with the host computer and the data concentration module through a communication unit. The data concentration module interacts with the data acquisition modules successively. The battery online monitoring system and method replaces a battery insulationmonitoring device, uses new technology to monitor multiple states of the battery, and provides a battery monitoring function. The battery online monitoring system and method prolong the service lifeof the battery, saves the purchase fund of the battery, detect hidden dangers timely and reduce power loss. By means of the battery online monitoring system and method, it is no longer required to manually detect the internal resistance of the battery regularly and verify the capacity annually by operation and maintenance workers.

Description

technical field [0001] The invention belongs to the field of on-line monitoring of accumulator information in substations and on-line maintenance of accumulators, and relates to an on-line monitoring system and method for accumulators. Background technique [0002] At present, most of the monitoring methods for battery packs are to install battery inspection devices, which have a single function, only monitor the voltage and current parameters of the entire battery pack, and require manual regular inspection and maintenance. Although there is currently a battery monitoring system that monitors the voltage and internal resistance of each single battery. However, the acquisition of the voltage of the single battery uses a voltage dividing resistor method, which affects the accuracy of the collected voltage, and then affects the accuracy of the analysis and judgment of the device. It also does not have the online monomer charging and discharging function and the battery monito...
