Abstract: A locomotive propelled by a hybrid power system includes a boost mode of operation accessible on-demand by the operator. When a throttle is set to deliver maximum power from a diesel-electric engine, an operator can select actuators separate from the throttle to request that a control module deliver additional electrical power from batteries. The actuators may be soft keys or a touchscreen on a computer monitor or mechanical switches as part of the locomotive cab. The actuators provide boost notches of additional power beyond the typical eight notches on the throttle at least for transient conditions, and existing locomotives may be easily and inexpensively retrofitted with the actuators.

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.
