  • Publication number: 20200162000
    Abstract: Systems and methods that utilize continuous field flash as integrated alternator heaters in a genset are disclosed herein. The method includes detecting that a generator set is in a non-rotating state, enabling a field flash circuit of the generator set to operate while the generator set is in the non-rotating state, and activating the field flash circuit so that current flows through and heats at least a portion of an alternator of the generator set and reduces a moisture on the at least a portion of the generator set.

  • Patent number: 10298161
    Abstract: Systems and methods for controlling a generator set are disclosed herein. The method includes determining a state of local modes selectable via a local interface proximate to the generator set. The local modes include a local standby mode and a local remote enabled mode. The method also includes determining a state of a plurality of remote modes using a command from a device remote from the location of the generator set in response to determining the remote enabled mode is active. The method includes, in response to determining the local standby mode is active, the remote enabled mode is active, and one of the remote modes is active, determining whether to activate or stop the generator set based on the active remote mode and disabling the local standby mode from controlling activation of the generator set.

  • Patent number: 9874190
    Abstract: Methods and systems for exercising a genset are disclosed herein. The method includes detecting whether the genset is in a first mode or a second mode, and activating a plurality of exercise cycles of the genset. Activating the plurality of exercise cycles comprises, in response to detecting the genset is in the first mode, ignite fuel to activate the genset during each of the plurality of exercise cycles of the genset; and in response to detecting the genset is in the second mode, cranking the genset without igniting fuel during at least a first subset of the plurality of exercise cycles.

  • Publication number: 20100186373
    Abstract: An electric power system includes a genset with an electric power generator, an internal combustion engine driving the electric power generator, and an electric heating device. This device may be used to selectively regenerate an exhaust treatment subsystem and/or to otherwise selectively increase load on the engine. In one application, the system is carried by a vehicle propelled by another engine. In another application, the system is structured to provide back-up power to an AC power bus, and is typically stationary.

  • Patent number: 7482704
    Abstract: This document discusses, among other things, systems, devices, and methods of disabling an automatic generator starting (AGS) actuator, such as used with a fuel-powered AC power generator providing AC electrical power to a recreational vehicle (RV) or other vehicle. The AGS actuator is disabled in response to a fault condition, such as may be indicative of a risk of hazardous gas, such as carbon monoxide (CO) accumulating near the vehicle, potentially in an enclosed area. After such disabling is performed, the vehicle driver would then have to consciously re-engage the AGS actuator. Factors useful for determining whether the fault condition exist include, among other things, transmission position, wheel rotation, vehicle engine operation status, ignition status, and/or an exhaust gas sensor.
