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.

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.

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.

Integrated power system control method and related apparatus with energy storage element

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.

A system and technique for purging condensate from an electrochemical cell stack prior to operating the stack in one of a power producing mode of operation and an electrochemical pumping mode of operation is provided. The system and technique include storing hydrogen in the anode and cathode chambers of the stack to place the stack in a shutdown state, purging the anode and cathode chambers of condensate prior to starting operation of the stack, and preventing a fuel starvation condition in the stack while purging by sequencing communication of a fuel flow and an oxidant flow to the anode chamber with an oxidant flow to the cathode chamber while purging the condensate.
