Abstract
An energy tender vehicle for use in connection with a hybrid energy locomotive system having an energy storage and regeneration system. The energy storage and regeneration system captures dynamic braking energy, excess motor energy, and externally supplied energy in one or more energy storage subsystems, including a flywheel, a battery, an ultra-capacitor, or a combination of such subsystems. In one form, the energy storage and regeneration system is located in the energy tender vehicle. The energy tender vehicle is optionally equipped with traction motors. In one form, the energy tender is configured to operate without any power connections to the locomotive. An energy management system is responsive to power storage and power transfer parameters, including data indicative of present and future track profile information, to determine present and future electrical energy storage and supply requirements. The energy management system controls the storage and regeneration of energy accordingly.
