Purpose: Development and approbation of the methodology of the definition of power expenses on booster charge of diesel locomotive rechargeable battery with the purpose to clarify tractive calculations. While definition of power expenses on charge of a battery it’s necessary to take into account the current state of a battery itself as well as of starter-generator implementing this battery charge. This task can be solved as a result of statistical analysis of information being registered by subsystem of board diagnostics of modern diesel locomotives. Methods: The methods of preprocessor treatment of information array and statistical analysis of formed sampling have been proposed. Results: Capacity probable values, spent on battery charge in the process of diesel locomotive exploitation, have been defined. With 95 % probability for 14 section of diesel locomotives of 2TE116U series, average charging capacity of rechargeable battery doesn’t exceed 2.6 kW at expected value of 1.4 kW. Practical significance: The obtained results allow to clarify capacity value selected for auxiliary needs and as a consequence to rise accuracy of locomotive tractive-energetic properties.
