Patent number: 9007027Abstract: Charging and discharging an energy storage device (ESD) generates heat and may prevent its temperature from dropping to unsafe levels. By monitoring and managing the charge and discharge of an ESD with respect to the periods of time in which demand charges are determined, the heating will have minimal adverse effect on demand charges. ESDs may also exchange energy in a controlled manner for heating purposes and reduce reliance on utility grid-based energy sources. ESD heating may also be made more efficient by offsetting the heating with load shedding during charging periods. Precharging the ESD while heating or preheating the ESD by charging and discharging can prevent new maximum demand levels from appearing and thereby limit increases in demand charges.Type: GrantFiled: January 31, 2012Date of Patent: April 14, 2015Assignee: Green Charge Networks LLCInventor: Ronald D Prosser

Patent number: 8829855Abstract: Some embodiments relate to a power generation system. The power generation system includes a first generator and a first battery charger. The first battery charger is adapted to charge a first battery and a second battery. The first battery and the second battery are each adapted to provide power to start the first generator. The power generation system further includes a controller that determines a state of charge for each of the first battery and the second battery. Based on the state of charge for each of the first battery and the second battery, the controller determines which of the first battery and the second battery receives charging current from the first battery charger.Type: GrantFiled: September 26, 2012Date of Patent: September 9, 2014Assignee: Kohler Co.Inventors: Eric D. Albsmeier, Richard A. Mauk, Harrison C. Chiu
