Patent number: 10509075Abstract: A diagnostic test is conducted by operating an engine-generator set at a plurality of reduced speeds. At each of those speeds, operating parameters of the engine are sensed and analyzed to detect an unsatisfactory operating condition. For example, such operating parameters may include speed of the engine-generator set, engine oil pressure and level, engine temperature, coolant level, and battery voltage. When a transition in engine speed occurs, a throttle test also may be conducted to measure how quickly and smoothly the engine reaches the new speed. After the engine reaches the normal operating speed, the generator is activated to produce electricity. One or more characteristic of that electricity, such as voltage, current and frequency, are sensed and evaluated to detect an unsatisfactory operating condition.Type: GrantFiled: January 5, 2015Date of Patent: December 17, 2019Assignee: Kohler Co.Inventors: Eric D. Albsmeier, Kenneth R. Bornemann, Harrison Chirkdo Chiu, Zane Eaton, Anthony James Hackbarth, Richard Allen Mauk, Jeffrey John Neis, Edward Douglas Brey

Patent number: 9369075Abstract: An alternator has a field coil that produces a magnetic field which induces electricity in a coil arrangement. A field coil excitation system includes a generator with an output coil assembly for producing alternating electricity. A rectifier converts the alternating electricity into voltage and direct current at two nodes. A capacitor, between the nodes, has capacitance that forms a resonant circuit with inductance of the output coil assembly. Due to that resonant circuit, the voltage and direct current oscillate in a predefined phase relationship. A switch and the field coil are connected in series between the nodes. A controller renders the switch conductive for a time period specified by a received control signal. The switch is rendered non-conductive at the first occurrence of a minimum current level after the time period ends. The predefined phase relationship enables the minimum current level to be detected by sensing the voltage.Type: GrantFiled: May 23, 2014Date of Patent: June 14, 2016Assignee: Kohler Co.Inventor: Eric D. Albsmeier

Patent number: 9293914Abstract: Some embodiments relate to a power management system that includes an engine-driven generator and a plurality of load switching and sensor modules that are located remotely from the generator. The load switching and sensor modules include power switching devices and/or sensor circuits.

Patent number: 9281716Abstract: A power management system may include a generator controller. The generator controller may (i) operate the generator; and (ii) prohibit a transfer switch from supplying first or second power to an output of the transfer switch. In some systems, the first power may be primary power (e.g., from a primary power source such as a utility) while the second power is secondary power (e.g., from a secondary power source such as a generator). In other systems, the second power may be primary power while the first power is secondary power, or both the first and second power may be secondary power.Type: GrantFiled: January 9, 2013Date of Patent: March 8, 2016Assignee: Kohler Co.Inventors: Eric D.
