Abstract: A method for operating one or more processors to control access of a plurality of pieces of rechargeable electrical equipment, optionally including one or more electric vehicles, to one or more charging resources. An access queue is maintained for each of the charging resources. Each piece of equipment is assigned a position in an access queue when it is determined to have a state of charge (SOC) less than the first level. Each access queue is updated based on charger information such as its availability. A piece of equipment is assigned access to a charging resource when its queue position reaches a first priority position and a charging resource is available. For each piece of equipment assigned access to a charging resource, an instruction to end access to the charging resource is issued when an elapsed charging time period is equal to or greater than a break time or the SOC is greater than a second level representative of an operational charge.

Abstract: The present invention relates to a hot shutdown monitor for an internal combustion engine, in which the engine control module (ECM) obtains engine operating information from various sensors and calculates an instantaneous load factor of the engine based upon various factors such as engine speed, engine fueling, exhaust manifold temperature, oil temperature, etc. This instantaneous load factor is preferably heavily filtered with the output of the filter determining a cumulative weighted load factor that represents a condition of the engine (i.e. the heating and cooling of the engine components). The present invention monitors for a shutdown request both from the operator (i.e. ignition keyoff or from other ECM control algorithms (i.e. engine protection). When an engine shutdown is detected, the weighted load factor is compared to a predetermined threshold. If the threshold is exceeded, a fault indicator is set within the ECM and the current engine data is captured for later retrieval.
