Tests of BMS Battery Management System with active and passive system of balancing the battery capacity

Abstract

The tests of two BMS Battery management systems, equipped with active and passive systems of balancing the battery capacity, realized within the framework of the HYDKOM 75 project, are discussed in the article. These test were performed on the lithium-ferric-phosphate(LiFePO4) battery assembly for the mining mobile machine of BH 3000 B HYDKOM 75 type. The object of tests included two Battery Management Systems (BMS). The first one was a commercially available system most often used in the automobile industry, however the second one was the author's BMS-Battery Management System developed at the KOMAG Institute of Mining Technology within a realization of the HYDKOM 75 project. The tests were conducted both during a battery charging process as well as during discharging the LiFePO4 battery for different values of the load current.
