Abstract: A power system for a locomotive includes an engine, an alternator, an electrical system, a primary load, an auxiliary load, a battery and a battery management system. The alternator is coupled to the engine. The electrical system is electrically powered by the alternator. The primary load, auxiliary load, and battery are electrically connected to the electrical system. The primary load is configured to provide the primary motive power for the locomotive. The battery management system is electrically connected to the battery and configured to monitor the battery and provide power to the auxiliary load when the engine is off and at least one battery condition is met. The battery management system is in communication with a back office to provide information on the at least one battery condition.
