Tests Of Electric Properties Of Supply-Control System Of Mining Floor-Loader

Tests of electric properties of the supply-control system designed for a floor-loader operated in underground mine workings, are presented in the article. The tests included functionality of the machine power electronics systems, consisting of the inverter controlling the induction motor and the charger of lithium-ion battery. The tests were concentrated on a verification of functional correctness of the system managing an operation of the battery (BMS) and its collaboration with the superordinated floor-loader control system. The obtained test results enabled to verify the accepted technical and functional assumptions of the supply-control system as well as to confirm a possibility of its safe operation in underground conditions (including the zones where an explosion hazard occurs). The supply-control system of the floor-loader is developed within the framework of the HYDKOM 75 project number POIR.04.01.02-00-0102/16, co-financed by the European Regional Development Fund.
