Принадлежит: Briggs & Stratton Corporation

An on-demand generator starting system and method is disclosed. The generator starting system is included as part of a standby or portable generator that includes one or more outlets that provide electrical power to an electrical device. The operating system includes a generator controller that monitors for a request for power from the electrical device connected to the outlet. When the control circuit of the generator controller determines that electric power is required from the generator, the control circuit initiates operation of the internal combustion engine. After the internal combustion engine starts, the control circuit operates a relay to provide power from the generator to the outlet of the generator. When the electrical device is no longer operating, the control circuit of the generator controller terminates operation of the internal combustion engine of the generator. In this manner, the generator operates only when the electrical device is requesting electrical power. 1. An operating system for a generator having an outlet and an internal combustion engine operable to generate a supply of electrical power to an electrical device connected to the outlet , the system comprising:a control unit;a switching device selectively operable by the control unit to connect one of a first input or a second input to an output, wherein the second input receives the supply of electrical power from the internal combustion engine;an outlet connected to the output of the relay through a power supply line;a current sensing device positioned to detect current flow through the power supply line and communicate to the control circuit;a starter circuit connected to the control unit and operable to initiate starting of the internal combustion engine;a power control circuit connected to the control unit and operable to switch the movable contact of the switching device to selectively connect the output to either the first input or the second input; andan ignition kill circuit ...
