SYSTEMS AND METHODS FOR COOLING POWER ELECTRONICS IN AN ENERGY STORAGE SYSTEM

Abstract:

An energy storage system is provided. The energy storage system includes a first housing comprising thermal insulation, the first housing defining a lower temperature region, at least one energy storage module positioned within said first housing, and an electronics assembly positioned within the lower temperature region of said first housing. The electronics assembly includes a second housing comprising thermal insulation, the second housing defining a higher temperature region that is thermally isolated from the lower temperature region, at least one power electronics component positioned within the higher temperature region of the second housing, and an air conduit extending through said second housing, the air conduit configured to channel ambient air external to the first housing through the higher temperature region to cool said at least one power electronics component.
