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) sysem, 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: A heat removal assembly for use with a power converter that includes a condenser and an evaporator coupled in flow communication with the condenser. The evaporator is configured to channel working fluid therebetween. The evaporator includes a supply housing, a receiving housing, and at least one expansion housing extending between the supply housing and the receiving housing. The at least one expansion housing includes a flow inlet defined at the supply housing and a flow outlet defined at said receiving housing, and the flow inlet is sized smaller in cross-sectional size than the flow outlet.
