Abstract
Application of battery powered mining locomotives with lead-acid cells is associated with secretion of hydrogen under charging. Modern systems of powering and control of these machines allow electrical braking with simultaneous energy recuperation. This however, increases the efficiency of operation while, increasing the risk of dangerous hydrogen concentration. The paper presents and discusses the results of both tests for real objects in mine and the results of relevant simulation analysis. The results were confronted with the formal applicable requirements. In this work also attempt to determine the correlation between the quality of electrical energy provided to the battery and the intensity of electrolytic gas emission.
