Abstract: An energy storage system (ESS) deflagration and thermal propagation mitigation method and corresponding systems prevent and, if necessary, suppress fires in ESS containers. The method uses a gas detection system, a smoke and temperature detection system, and a fire suppression system. The gas detection system opens a vent in response to detecting a concentration of gas that meets or exceeds a threshold concentration. If needed after venting the container, the smoke and temperature detection system closes the vent and activates the fire suppression system in response to detecting both the presence of smoke and a temperature that meets or exceeds a threshold temperature.

Abstract: A micro grid power system includes a plurality of generator sets, a photovoltaic system, an external load, and a controller. Each generator set includes an engine and a sensor to determine a temperature of exhaust gases exiting the engine. The photovoltaic system includes a plurality of photovoltaic panels for generating power. The external load is powered by the plurality of generator sets and the photovoltaic system. The controller is configured to determine the external load, and control the plurality of generator sets to maintain the temperature above a threshold temperature. The controller is further configured to determine a remaining load which is the external load subtracted by a portion of the external load powered by the plurality of generator sets, and control the photovoltaic system to power the remaining load.

Abstract: A variable speed genset system is provided that may include a primary power source, an electric machine, an energy storage device, a boost converter, and a controller. The electric machine may be coupled to the primary power source and electrically coupled to a load through a common bus. The boost converter may be in electrical communication with the common bus and the energy storage device. The controller may determine a State of Health (SOH) for the energy storage device, selectively engage the energy storage device to provide a first power amount to the common bus, and selectively change the operating speed of the primary power source to provide a second power amount to the common bus, the speed based on the SOH, a temperature of the energy storage device, and the load demand. The combination of the first and second power amounts substantially meet a load power demand.

Abstract: An energy storage device cooling system includes a housing, at least one energy storage device within the housing, and a coolant circuit including a first flow portion extending through the housing, the coolant circuit configured to supply coolant for heat exchange with the at least one energy storage device. The energy storage device cooling system also includes a chiller system including: a coolant supply, a heat exchanger, and an outlet in fluid communication with the first flow portion. The energy storage device cooling system also includes a controller configured to alter a function of the chiller system when a sensed temperature does not exceed a first temperature threshold.

Abstract: In one aspect, a thermal management system includes a first coolant circuit, through which a first coolant circulates, and including at least a radiator for cooling the first coolant, a storage containing one or more power electronics, a heat exchanger, and a thermostatic valve that outputs the first coolant to at least one of the storage containing the one or more power electronics and the heat exchanger. A second coolant circuit, through which a second coolant circulates, includes the heat exchanger configured to cool the second coolant using the first coolant, an energy storage unit cooled by the second coolant, and a refrigeration unit configured to cool the second coolant. A coolant temperature sensor outputs a temperature of the coolant in the second coolant circuit, and a controller controls at least the refrigeration unit based on the temperature of the coolant output by the coolant temperature sensor.
