Patent number: 10920665Abstract: A method and system for exercising a standby generator is disclosed. The standby generator can be exercised in at least two different exercise cycles, including an express exercise cycle and an extended exercise cycle. The system and method operates the generator for an express exercise cycle having a first duration when the ambient temperature at or near the standby generator exceeds a minimum threshold temperature. If the ambient temperature does not exceed the minimum threshold temperature, the express exercise cycle does not begin. In addition to the express exercise cycle, the engine of the standby generator is started and run for an extended exercise cycle having a duration that exceeds the duration of the express exercise cycle. The extended exercise cycles are separated by a first interval while the express exercise cycles are separated by a second interval, where the first interval is longer than the second interval.Type: GrantFiled: July 25, 2019Date of Patent: February 16, 2021Assignee: Briggs & Stratton, LLCInventors: Michael Miller, Dean Weigand, Rick Jungmann, Robert Townsend
