Abstract

The invention provides an intelligent single battery management system. The intelligent single battery management system comprises three modules: an intelligent single battery acquisition module IBU,an intelligent battery pack management module BMU and an intelligent battery pack display module BDM, communication is established between the IBU and the IBU module and between the IBU module and theBMU module in a wireless or two SBUS serial bus communication mode. The BMU module establishes communication with the BDM module or the upper computer through an RS485 communication mode. According to the invention, the data acquisition speed and precision are effectively improved, the workload is reduced, and wiring is simple.

Description

technical field [0001] The invention relates to the battery field, and is particularly applicable to the measurement and maintenance of an intelligent single battery management system. Background technique [0002] With the advancement of science and technology, valve-regulated sealed lead-acid batteries have the advantages of light weight, small footprint, and no acid mist pollution. While valve-regulated lead-acid batteries have outstanding advantages, there are many shortcomings, such as: difficult to test capacity, high requirements for float voltage and use environment, etc. This puts forward new requirements for battery test equipment. Therefore, while improving battery performance and reducing maintenance workload, how to quickly and effectively detect early failure batteries and predict battery performance trends has become the top priority of battery operation and management. Although the centralized management of battery packs improves the speed and accuracy of d...
