Patent number: 12630035Abstract: Systems and methods are provided for managing Electric Vehicle Supply Equipment (EVSE) for use with a generator back-up. The EVSE can receive electrical power to generate an electrical load while monitoring a frequency of electrical power. The EVSE and/or another system may determine the generator back-up is supplying power based on the frequency. In response to determining the generator back-up is supplying power, the EVSE can operate at percentage of full power. The EVSE may attempt to reconnect and/or increase the percentage of full power in multiple ways based on a mode the EVSE is operating in. In a lock-out disabled priority mode, the EVSE can attempt to reconnect and begin operating at full power. In a lock-out mode, the EVSE can attempt to reconnect at a percentage of full power and incrementally increase the percentage of full power until full power has been reached.Type: GrantFiled: May 9, 2024Date of Patent: May 19, 2026Assignee: Generac Power Systems, Inc.Inventors: Austin George Baeten, Nicholas Scott Karfonta, Brandon Michael Schmidt, Daniel Luke Kempema, Samuel Benjamin Desens, Nicholas James Schmidling

Publication number: 20250321018Abstract: Systems and methods are provided for managing electrical devices for use with a generator, and, particularly, climate control (e.g., Heating, Ventilation, and Air Conditioning (HVAC)) management systems and methods for use with a generator. A climate control energy management system or controller, such as a thermostat, can monitor the frequency of the source power to determine if power is supplied by a generator or a utility. If the thermostat determines that the source of energy is generator power, the controller can determine whether the generator is reaching full capacity. If the generator is reaching full capacity or is at full capacity, the thermostat can reduce the climate control load or otherwise adjust the operation of climate control system.Type: ApplicationFiled: April 11, 2025Publication date: October 16, 2025Applicant: Generac Power Systems, Inc.Inventors: Joshua Stangel, Nicholas J.
