Patent number: 9913406Abstract: A system and method for controlling ambient temperature at a power-consuming site includes a hybrid generator-battery power system. The generator-battery power system includes an engine-generator set and one or more DC-powered batteries that alternately share the site load. Thus, the method includes providing one or more temperature sensors communicatively coupled to a battery management system at the power-consuming site. Another step includes monitoring the ambient temperature of the power-consuming site via the one or more temperature sensors when one or more of the DC-powered batteries are discharging (i.e. when the engine-generator set is off). The method also includes sending, via the battery management system, a start-up command to the engine-generator set when the ambient temperature of the power-consuming site reaches a threshold temperature such that the engine-generator set can provide AC power to an air conditioning unit at the power-consuming site.Type: GrantFiled: July 31, 2014Date of Patent: March 6, 2018Assignee: General Electric CompanyInventors: Christopher James Chuah, Mark Edward Gotobed, Shanon Kolasienski, Scot Sakolish

Patent number: 9692245Abstract: Example aspects of the present disclosure are directed to an improvement of an energy storage system. The energy storage system includes a power connector and a battery management system (BMS). The power connector includes a connector body having a first face and a second face which is disposed oppositely to the first face. A first terminal and a second terminal can be disposed on the first face. The first terminal and the second terminal can be configured to electrically couple the BMS to a positive conductor and a negative conductor to form a power connection, Moreover, a first current shunt can be disposed on the second face and electrically coupled to the first terminal, while the second current shunt can be disposed on the second face and electrically coupled to the second terminal.Type: GrantFiled: August 31, 2015Date of Patent: June 27, 2017Assignee: General Electric CompanyInventors: Michael Stanley Zanoni, Christopher James Chuah

Patent number: 9496748Abstract: Systems and methods for controlling a hybrid power architecture to provide fuel or energy savings. Recharge time of an energy storage device (ESD) is reduced through the application of a controlled potential and ESD recharge time management over the life of the hybrid system through manipulation of the ESD charge state window of operation. Fuel or energy savings is achieved by controlling the partial-state-of-charge (PSOC) window of the ESD based on a recharge resistance profile of the ESD and by controlling a charging potential applied to the ESD based on a recharge current and/or the estimated recharge resistance profile of the ESD.Type: GrantFiled: July 12, 2012Date of Patent: November 15, 2016Assignee: General Electric CompanyInventors: Christopher James Chuah, Herman Lucas Norbert Wiegman, Donald Wayne Whisenhunt, Jr., Roger Neil Bull, Kalyan Bukkasamudram, Connor Brady, Mark Gotobed

Publication number: 20160061173Abstract: The present disclosure is directed to systems and methods for determining health of an engine-generator set of a hybrid power system having at least one battery power source. For example, in one embodiment, a battery management system sends a start-up command to the engine-generator set. After sending the command, at least one start-up condition (e.g. a start-up time lapse, a start-up voltage parameter of a starter battery of the engine-generator set, or a voltage of the battery power source before sending the start-up command) is determined for the hybrid power system. Next, a start-up condition trend is generated based on a plurality of the start-up conditions over multiple start-ups. Thus, the engine-generator set health can be determined based on a comparison of the start-up condition trend and a threshold start-up condition for the engine-generator set.Type: ApplicationFiled: August 27, 2014Publication date: March 3, 2016Inventors: Christopher James Chuah, Shanon Kolasienski, David E.

Publication number: 20160043580Abstract: The present disclosure is directed to a system and method for reducing current variability between a plurality of energy storage devices, e.g. battery modules. In one embodiment, the method includes determining a resistance of at least two of the plurality of energy storage devices. Another step includes modifying an operating temperature of one or more of the plurality of energy storage devices when the resistance of one or more of the energy storage devices is outside of a predetermined tolerance range for the energy storage devices. Thus, the step of modifying the operating temperature of one or more of the plurality of energy storage devices causes the plurality of energy storage devices to operate within the predetermined tolerance range.Type: ApplicationFiled: August 7, 2014Publication date: February 11, 2016Inventors: Kenneth McClellan Rush, JR., Christopher James Chuah, Chester Stanley Jezierski, JR., Leng Mao, David E.

Patent number: 9147910Abstract: A system and method of use including a controller responsive to a deviation in absolute value or relative slope and operable to terminate a discharge operation in an energy storage device is provided. The absolute value or relative slope is determined at sampling frequency based upon a combination of measured operating parameters, for example, potential and current. Any deviation in the absolute value or relative slope indicates that a threshold limit in the available energy of the system has been reached, for example when active materials in the device are at a point of depletion, indicating a need to cease the discharge operation. The system and method operate on a real-time basis, providing instantaneous SOH information with regard to the device.Type: GrantFiled: December 28, 2011Date of Patent: September 29, 2015Assignee: General Electric CompanyInventors: Christopher James Chuah, Roger Bull, James Sudworth, Vincent Boccanfuso, David James
