Energy reserves of accumulatory batteries in locomotive transport of industrial enterprises.

The reserves of production capabilities of traction batteries of intra-production and inter-production rail narrow-gauge transport problem is considered. The article defines the maximum length of industrial cargos transportation by 2AM8D battery electric locomotives with a route that corresponds to the slope of equal resistances, based on the factors of battery energy capacity and duration of the work shift. The factors that determine the maximum length of cargo transportation by a battery electric locomotive for different number of locomotive trips are established: the average energy capacity of the battery and its average discharge voltage, the operating current in the locomotive engines, the duration of the work shift and pauses for shunting, final and other operations, the delay of the locomotive in the trip. The energy capacity reserves of the locomotive battery in industrial enterprise were estimated for work shifts lasting 6 and 8 hours on the example of the use of 2AM8D mine battery electric locomotives both in underground conditions and on the surface for intra-production and inter-production transport. As result of study was established: the main limiting factor for the maximum length of cargo transportation by battery electric locomotive is the duration of the work shift; it is possible to limit the maximum length of transportation based on the energy capacity factor of the battery when the duration of the work shift is 8 hours. and more with a small quantity of locomotive flights; for a shift duration of 6 hours when the number of locomotive flights is more than 7 the maximum length of transportation by a locomotive is limited by due to the excessively long total time of the pause on the shunting operations, and at the quantity of trips over 16 transporting is technically impossible to carry out due to the length of the work shift.
