Abstract

This invention provides a distributed battery management system, comprising a managed battery group, battery monitoring units, on-site control host and a server. The distributed battery management system can collect the voltage, current, internal resistance and temperature of the battery through the battery monitoring units distributed on the managed battery and transmits the voltage, current, internal resistance and temperature of the battery to the on-site control host. The on-site control host reports the received battery parameter information to the server which stores the received battery parameter information and analyzes the battery performance according to the battery parameter information. In the meantime, the distributed battery management system also has a capability of charging equalizing management. The distributed battery management system realizes the distributed remote monitoring for the battery group and charging equalizing management.

Description

technical field [0001] The invention relates to a device in the field of battery technology, in particular to a distributed battery management architecture. Background technique [0002] The principle of the storage battery is to convert chemical energy and direct current energy into each other, and restore the energy after charging after discharge, so as to achieve the effect of repeated use. With the rapid development of my country's communication, electric power, UPS and other industries, the consumption of batteries is also increasing rapidly. As far as the current usage conditions of our batteries are concerned, some unexpected situations often occur, such as when a seemingly normal battery discharges, it cannot discharge electricity. The main reason for this situation is that the operating status of the battery has not been effectively monitored. Once a certain battery fails in a battery pack composed of multiple batteries connected in series, it will cause the entire...
