Development of a Model of a Source of Stabilized Battery Charge Current on Electric Trains with Rheostatic Braking

From the analysis of the operation of electric trains of the ET2, ET2M, ED2T, ED4M, ED4MK series, it was revealed that their failures in some cases are associated with battery failure. The aim of the work is to increase the reliability of the technical condition of the fleet of suburban rail vehicles, by developing and improving scientifically based methods aimed at increasing the life of batteries and control circuits in general. The analysis of charging circuits for rechargeable batteries and power supply of control circuits on electric trains is carried out. A scheme has been developed for stabilizing the charging current of batteries on electric trains. The elements of the circuit of a voltage regulator are calculated and its model is compiled. The analysis of the operation of the circuit based on the transients that accompany the operation of the charger in the process of charging the battery. The analysis confirmed the working ability of the circuit and the correct calculation of its elements. Comprehensive all-season operational tests have confirmed the high efficiency of the developed battery charging circuit eliminating overheating, recharging, and in some cases an explosion, as well as eliminating thermomechanical defects in the control circuits. The developed charging scheme was put into continuous operation on an electric train of the ET2M and ED2T series.
