Abstract: An energy storage system includes a DC bus; a plurality of battery strings, each battery string comprising batteries coupled electrically together; a plurality of DC/DC converters electrically coupling respective battery strings to the DC bus; an enclosure housing the battery strings and the DC/DC converters; and a temperature control system. The temperature control system includes at least one heating, ventilation, and air conditioning (HVAC) system, and a controller. The controller is programmed to execute a method of predicting heat loads for respective battery strings within the enclosure, wherein the heat loads comprise external heat loads and internal heat loads; determining one or both of DC/DC converter operating commands and HVAC operating commands based on the respective predicted heat loads to control the actual heat loads of the respective battery strings; and operating one or both of the DC/DC converter and the HVAC system in response to at least one of the DC/DC converter operating commands and the HVAC operating commands.

Abstract: An energy storage system includes a plurality of battery strings, each battery string including a plurality of batteries coupled electrically together; a plurality of temperature sensors; an enclosure housing the plurality of battery strings and the temperature sensors; a plurality of fans positioned in different locations within the enclosure; and a temperature control system. The temperature control system includes a heating, ventilation, and air conditioning (HVAC) components, and a controller. The controller is programmed to execute the method that includes determining fan speed operating commands based at least in part on sensed temperatures at the different locations, and operating the fan speed in response to the operating commands provided to the respective fans.

Abstract: A heat transfer assembly useful for dissipating heat from the heat emitting device is disclosed. The assembly includes a module inlet for receiving a coolant, at least one module having a first part with a recess to receive a portion of the heat emitting device, and a second part having a shaped cutout portion and a solid portion, where the second part allows a uniform compression of a seal component disposed on the first part. The first part and the second part are mechanically connected to each other; and a module outlet is used for discharging a heat absorbed coolant after absorbing heat from the heat emitting device, where the at least one module is connected to the module inlet and the module outlet. In another embodiment, multiple modules are configured in a symmetrical layout to provide a balanced flow of the coolant in the heat transfer assembly.
