Review of structural battery designs used on mine electric locomotives

Introduction. The use of alkaline and lead-acid batteries in electric locomotives of mining enterprises is currently relevant. There is a need to study the requirements for mine electric locomotives and identify the advantages and disadvantages of electrochemical systems. Research aim is to conduct a comparative analysis of the applied electrochemical systems of mine locomotives, consider the advantages and disadvantages of batteries used in mine electric locomotives, and consider the processes that occur when charging and discharging batteries. Methodology. A review of existing electrochemical systems used on electric rolling stock in the conditions of mine workings is carried out. The processes of charge-discharge of alkaline and lead-acid batteries are considered. Results. This article analyzes the electrochemical systems used in mine electric locomotives, of which two can be distinguished. Lead-acid batteries have a number of significant drawbacks that limit their operating conditions. Alkaline batteries are more widely used as an energy source for mine electric locomotives. Findings. The main types of electrochemical systems used in mine locomotives are highlighted. Their main advantages and disadvantages are examined, from which it follows that the data on the type of batteries operate using caustic substances, which requires additional measures to ensure safe operation.
